3 Cool Things About SolarWorld Solar Panels
Here at the alte store, we sell several quality brands of solar panels.I wanted to share with you 3 reasons that make solarworld brand of solar panels so darn cool.Number 1 solarworld has been manufacturing solar panels in the usa for 40 years.They’ve been making panels in the usa since 1975.Yes, making solar in the usa since 1975, the same year that bic invented disposable razors, sony introduced betamax tutorialtapes, and ‘one flew over the cuckoo’s nest’ won the oscar for best picture.As of now, in 2015, they employ over 1300 people in america.
That’s 1300 jobs in the us clean energy market! number 2 solarworld’s solar panels are really strong.Their new version 4 frame provides increased load ratings, reduces the impact of scratches, and drains water faster.As a result, you can mount the solar panels in any orientation, portrait or landscape, and it can withstand a static load of up to 113lbs per square foot.Solarworld voluntarily puts their panels through extreme tests that go far beyond what is required by international standards.They test for hail, salt spray, snow and wind load.They repeatedly drop a 99pound, leadfilled.
Sack from a height of four feet onto the middle of vertically positioned solar panels.They put their solar panels through extreme temperature fluctuations in order to emulate 25 years of weather changes.In the climate chamber, they cycle from 40 degrees to 185 degrees fahrenheit.Not just the for required 200 cycles, but 9,125 cycles.Number 3 you get more than you pay for.Solarworld plus sorts each solar panel off the assembly line.What that means is every single panel gets tested under standard test conditions.They get sorted in 5 watt increments, always rounded down.
So if a panel measures at 264 watts, it will go into the 260 watt bin, it doesn’t round up to 265 watts.If it is 269 watts, then it goes into the 265 bin.So you are guaranteed to get at least the rated wattage, not plus or minus, only plus or equal to.Their efficiency has gotten so good, that they are are currently making solar panels of up to 340 watts! solarworld solar panels come standard with a 25year linear power performance guarantee.This guarantees that for 24 years, the solar panels will not lose more than 0.7 of their.
Solar Panel Installation Which guide
Are you thinking about installing solar pv panels at your home producing your own electricity from solar is not any great only to the environment but it can also save money to the long term thanks to the feed in tariff and it can protect you from rising electricity bills.But the decision to install solar pv panels on your home is a big one.It can be nerve wracking when you’ve never seen how it’s done.So we filmed a solar panel installation to show you what happens and the answers to some of those common questions.
But first, let’s find out how the system works.Solar photovoltaic panels generate electricity whenever it’s light.Light energy from the sun hits the photovoltaic cells on the solar panel and is transformed into electricity.Conducting wires carry the electrical current from the your panels to the inverter and then into your home.When it’s light and you turn your electrical appliances on they’ll be powered by electricity your generating.Any excess electricity will be exported to the national grid.If you turn your appliances on when your panels aren’t producing electricity, you’ll use electricity from the grid as usual.
Before the installation process can again will have to arrange a survey with a reputable solar panel installation company.And the number of panels that you put on your roof depends on a number of factors the size of your roof, the direction which it faces, the amount of electricity that you wish to generate and how much you wish to spend.The installation will be done in stages.The whole process can take as little as one day, depending on the size of the system.We caught up with solar panel installation company manager guy hewitt to see an installation.
In process the process is quite straightforward actually.Before we get to the site we would have already surveyed it, so we’ll have produced a detailed plan of what we’re going to do on the roof.When we arrive if the scaffold tears up than the towers will be up.The next phase is to mark out and set out the array on the roof so then we’ll be taking the dimensions that we’ve got be lifting tiles, finding the rafters and setting out where we actually are going to insert the roof hooks into the roof.
the stage after that is, we start installing the roof hooks.So we lift the tile up, we find the rafters, we then insert the roof hook into the rafter, then the tile would sit back down and be weathered if necessary, and that goes all the way along the roof to create, if you like, parallel lines of roof hooks.After that the rails are bolted onto the roof hooks and when they’re fully secured and in position then the panels can be installed onto the rails.The vast majority of roofs in the united kingdom are able to take solar panels.They.
Need of course to face the right way.We wouldn’t be installing solar panels on a north facing roof.We’re really looking for somewhere from east to west or south of that.One of the concerns a lot of people have is that there’s a possibility that installing solar panels could actually damage your roof.That is not the case.Provided the right roof bolt is used for the type of tile that’s on the building, and the roofers have done a professional job, then the roof will be weather proofed..
In the house, the direct current from the solar panels comes in through this cable and it goes into an inverter box which converts the direct current to alternating current, which is safer for your home.And there are two isolator switches there’s a direct current isolator switch and an alternating current isolator switch as safety measures.From here the power is passed around the house and here you have the generation meter which indicates how much power your solar panels have created.As long as there is enough light the panels start producing electricity immediately.

Bill Nye Presents Rayton Solar
we can convert sunlight into electricity with a couple of thin silicon wafers in a sandwich, laughs a very thin one.For decades, to get a thin piece of pure silicon we had to saw it off a thick piece of pure silicon.The saw turns a lot of that silicon into dust.This process is fine for making integrated circuit chips for computers or smartphones because the amount of silicon used is so small.But for manufacturing big solar panels out in the wide open spaces, it costs a lot to waste a lot of pure silicon.
The gang at rayton solar has come up with a way to chip off an extraordinarily thin piece of pure silicon not with a saw but with a subatomic particle accelerator, an atom smasher.Well, it doesn’t smash atoms as such it smashes protons into the atoms of a chunk of silicon.Technicians can control the depth to which these particles penetrate with precision so they can place the particles perfectly.Once the particles are perfectly in place, rayton gives them a nudge, using a little bit of heat of just the right magnitude,.
And a perfect superthin slice of pure silicon is set free.A little bit of pure silicon goes a long way, so rayton can use the very purest silicon, which makes for a much more efficient conversion of light into electricity.Rayton then makes the silicon slices into solar panels in the conventional fashion a smidgen of phosphorous and a dash of boron, and there we go, a perfect panel with 90 less pure silicon than the good old days, which are actually right now and they’re really not that good.
With its patented technology, rayton solar is capable of making 100 times as many solar panels with the same amount of silicon as its competitors use to make just one panel.Rayton’s technology can produce electricity that’s clean and cheaper than electricity produced with greenhousegasemitting fossil fuels.It’s new.It does more with less.It’s less expensive and much more efficient.In the coming years, the sun will be a mainstay of the world’s energy.With rayton solar’s technology, solar power can be far less expensive than combustible fuel.Once panels are in place, the clean energy is free!.
For decades.We’re at the beginning of a new age, a future powered by clean renewable energy.The international energy agency predicts that solar energy will be the world’s largest source of electricity by 2050.Right now it’s less than 1.We stand on the cusp of a new era in which the paradigm for energy is changing.The last similar moment in history was over 100 years ago when oil became the new main energy source, replacing coal.An opportunity to back a disruptive solar technology represents a path to enabling change to a renewable future.
VISIONS CTRLP Australias Largest Solar Cells
Melbourne researchers have successfully created australia’s largest and most flexible solar cells, with the aid of a new printer located at csiro.The scientists are part of a collaboration between research and industry partners called the victorian organic solar cell consortium vicosc.This was achieved through the collaboration between the university of melbourne and the bio21 institute, csiro, monash university and industry partners including bluescope steel and security printing firm innovia security.In just three years the consortium has gone from making cells the size of a fingernail, to cells 10 centimetres square.
They are now able to print organic photovoltaic cells the size of an a3 sheet of paper.The consortium is now leading the world in the ability to print solar cells and using different printing technologies, but this is the beginning of the story.We’re still developing the technologies, still developing the materials to enable us to print in a number of different ways for different applications.The new printer can roll out 10 metres of solar cells per minute, which is equivalent to producing one cell every two seconds.Using semiconducting inks, the researchers print the cells.
Straight onto paperthin flexible plastic or steel.So what we’re looking at is, how can we use this technology in the short term, how can we print solar cells to enable advertising, can we put solar cells on to advertising material in shopping centres to drive an active display.So if somebody wants to advertise something with nice flashing lights then at the moment they drive that with batteries.In the longer term we see these materials being able to be coated on to buildings, into windows and on roofs to provide.
Power in a wide variety of locations and circumstances.As part of the consortium, graduate students working alongside scientists are involved in training and development programs to improve the technology in the long term.We’re now right up there with the rest of the people in the world but we’ve also got a facility which is different.We now have a process through our collaboration where we take things from the very very beginning, from designing materials, from making devices in the lab scale right through the large scale printing, which is very very unusual in the world context.
Solar Panels Batteries Solar Power Components Part 1
Hi.I’m amy beaudet from the alte store.Thank you for watching our tutorial series.This third tutorial is called solar electric components , and we’re going to break it down into multiple parts to keep it manageable.If you missed our earlier tutorials, i recommend you go back and watch the earlier ones in the series to get a good foundation.We regoing to go over some of main components in a solar electric system the solar modules, batteries.Keep in mind that technology is moving forward at an incredible rate, so i’m going to make.
Some generalities that are true today, but there are likely to be exceptions to most rules discussed.Before we go further, i want to go over a quick reminder on wiring in series vs parallel.Wiring panels in series, where the negative of one is wire to the positive of the other, results in the current staying the same, but the voltage increases.Two panels in parallel, where the two positives are wired together and the two negatives are wired together, results in the voltage staying the same and current increasing.It s important to note.
That regardless of the way it is wired, the power, or watts, remains the same.Since watts equals volts x amps, it doesn’t matter if it is series or parallel.Likewise, when batteries are wired in series, their voltage increases, and when wired in parallel, amp hours are increased.You’ll often see multiple rows of panels or batteries wired in series, each row is a string.You can then wire multiple strings in parallel.This allows you to get both higher voltage with series strings and higher amps or amp hours with parallel.
In this example of 2 parallel rows of 4 batteries wired in series is called 2 strings of 4.You can see that wiring 4 12v batteries in series equals 48v, and wiring those 2 strings in parallel doubles the amp hours to 160ah.The power of this array is 160ah x 48v, which equals 7680 watt hours.Let’s start with the solar panels, or pv modules.Solar panels generate dc electricity when exposed to sunlight via the photovoltaic effect, first observed by a french physicist in 18′.A simple explanation is that the photons from sunlight are absorbed.
By a semiconductor material, generally silicon.The negatively charged electrons are knocked loose from their atoms, and flow from the negative side to the positive side to recombine with available holes there.This creates a direct current flow.This flow of electrons can then be used to either directly power a dc device, like a pump or a fan, it can be used to charge a battery bank, or it can be inverted to ac power to use in your home.Each solar cell generates about 12v.That’s not much for practical use.So multiple cells.
Are wired together in series to create higher voltage, creating a solar module, commonly referred to as a solar panel.A typical 12v solar panel has 36 cells in series.The larger a solar cell is, the higher the current.So the cells of a 200w panel are generally bigger than a 100w panel.Multiple solar modules wired together then creates a solar array.You can see the difference in the look of a 12v module compared to a 24v module.As with anything, there are exceptions.We do have some 12v modules that have 72 cells,.
But the cells are wired in 2 parallel strings of 36 in series, creating the 12v.Each module has a label on the back, stating their specs.Here s an example of a kyocera 140w 12v module.It lists the rated outputs for the panel, as well as any certification it has.The ratings are actual outputs under standard test conditions, so the numbers you measure in the real world may be slightly different.Let s go over each of the specs for a solar module.Open circuit voltage is the voltage you will measure when nothing but a voltmeter is connected to the.
Solar panel.This is the highest voltage the module will output at 77 degrees fahrenheit with the sunlight intensity at 1000 watts per square meter, which are just a few of the details of standard test conditions, or stc.The voltage will be higher when it is colder out, and lower when it is hotter.Short circuit current is the amps output with no load on the panel.It is the highest current possible at stc.There are times when the output could be higher, for instance when the sun is coming out from behind a cloud,.
You can see the silver lining , where the edge of the cloud is magnifying the sunlight, causing the intensity to be brighter than stc.This brings us to the two specs which are when the module is connected to a load, so more real world conditions.But still at the temperature and brightness listed under stc.Maximum power voltage is the actual voltage the module will output when connected, and maximum power current is the amps output while under load.Pv modules were originally designed to charge battery systems, so it is typical.
To see panels listed for what voltage battery bank it is able to charge.Nominal voltage is a shorthand grouping term, originally based on battery voltages for example, 12v, 24v, 48v.To charge a 48v battery bank, you simply wire four 12v modules or 2 24v modules in series to add up to 48v.In general, you can determine what nominal voltage the module is by the number of cells on the panel.A 12v nominal panel usually has 36 cells, and its open circuit voltage is about 22 volts, and its maximum power voltage is around 17.
Volts.However, as gridtied solar systems that don’t use batteries have become more popular, you start to see different size nominal panels that don t logically line up with battery bank sizes.The most popular size modules used in gridtied systems today are 60 cell, 20v modules.The wattage of available panels has been increasing, and many manufactures are achieving that by increasing the number of cells, increasing the voltage of the panels.As you recall, watts equals volts times amps, so increasing the volts while maintaining the same amps increases the watts.As such, there are 80 cells and higher available these.
Days.Let s move off pv modules onto batteries.Solar panels have no way to store power, you use it or lose it.Batteries allow you to store power to use later, by using the power generated by the module or other power source to charge the batteries.Batteries used in a solar system must be deep cycle batteries.These are made very differently from car batteries.A car battery has the internal plates designed to send a short, high current blast to start the engine.It then gets recharged quickly by the alternator to send another short blast.
Hours later.A deep cycle battery is designed differently.It is designed to be gradually charged and discharged over a course of hours.If you try to use a car battery for an offgrid system, it will work for a short amount of time, but you will very quickly kill the batteries.Pv systems can have many batteries, each of them can weigh 50, 100 pounds, or much more.Additionally, there are losses inherent in batteries as they convert electrical energy to chemical and back to electrical 515 of energy lost to storage and extraction.
Additionally, you should never use more than 50 of the rated capacity, or you will quickly reduce the battery s ability to hold a charge, and have to replace the bank.These losses need to be taken into account when calculating the size of your battery bank.When selecting a battery for your system, there are 2 primary types of batteries available, flooded or sealed.A flooded lead acid battery has removable vents that you must remove to check the specific gravity of the acid and add water on a regular schedule, usually once a month.Because it.
Is not sealed, it is designed to output the hydrogen gas that is created during its charging process.Therefore the battery bank must be properly vented to the outside.If you are looking to have flooded batteries shipped, be aware that they are considered hazardous material by the department of transportation, so additional precautions and expenses may be required.The advantage of these flooded batteries is that they are less expensive than a typical sealed battery, and a well maintained flooded battery will generally last longer than a typical sealed battery.But if you neglect the battery and do not.
Handle the maintenance, you will quickly have a dead battery bank on you hands.Sealed lead acid batteries are most commonly available as either agm or gel.This refers to the form of the electrolyte.An agm battery has the electrolyte in a spongey mat, and the gel batteries have a thicker gel that keeps itself distributed within the battery.There are pros and cons to each of these designs that we won t get into, but in general , both types of sealed batteries are very similar.The biggest pro of sealed batteries is that since.
They are sealed, they won’t spill or outgas.This makes it a safer option than flooded batteries.They also don t require the monthly maintenance, just occasionally inspect them to see that they look to be in good shape.Sealed batteries are an excellent choice for battery backup systems that aren’t charged and discharged every day, but require a long standby period.They also do better in extreme cold.The downside to the sealed batteries is that they tend to be more expensive than a flooded battery, and have a shorter life.
Than a well maintained flooded battery.But it you are not able or willing to maintain a flooded battery, sealed is definitely the way to go.Just as watts volts x amps, watt hours volts x amp hours.This will come in handy when we size our battery bank.Many people ask how long they can run things from a battery.This depends on how deeply you discharge the battery, known as depth of discharge, and how quickly you are drawing current out of the battery.If you are drawing 2 amps out of a battery for 4 hours, this is using.
8 amphours.As i mentioned before, you don t want to use more than of the stored power in a battery, so the most power you want to take out of a 92 amp hour battery is 46ah.So if you are running that same 2 amps for 23 hours, you would have drained the 92 ah battery to 50 depth of discharge.The amount of power that a battery can store varies based on a number of variables, including how fast you charge and discharge the battery.In this example, you see that if you charge andor discharge the battery over 5 hours and a rate.
Of 49 amps, it can store half the power than if you did the same over the course of 100 hours at 4.6a.Most batteries are rated at 20 hours, basically how much power you can use during a day.If you are using power faster or slower than 20 hours, you must adjust the sizing accordingly.The amount of power that a battery can store varies based on a number of variables, including how fast you charge and discharge the battery.In this example, you see that if you charge andor discharge the battery over 5 hours and a rate of 49 amps, it can store half the.

Solar panels for the beginner part 6 Missouri Wind and Solar Harbor Freight
Hi everybody, i’m jeff from missouri wind and solar and this is another part of solar panels for the beginner.I know all the guys that are just beginning are probably really confused about all the different types of solar panels out there and all the different voltages so i’m gonna kind of explain, and i’m not gonna get really in depth, i’ll just give you an idea of the difference between one over the other.What i’ve got right here is a one hundred watt solar panel, and this is a.
Hundred watt solar panel, and that is a 15 watt solar panel over there.This is a monocrystalline, and that’s a polypolycrystalline, that over there is called a thin film amorphous solar panel.So how can you tell the difference well, monocrystalline solar panels are usually black like this and they will have these little cut corners, the diamonds in here, they’re really easy to spot as you can see see the shape them.Now, polycrystalline will always be rectangular cells and they’ll be different shades of blue.Sometimes you’ll see little chips through the.
The cells like that.Now, amorphous or thin films will be just a black panel like this and you’ll see a little thin wire going through it.People ask me all the time which solar panel is better.Well, none is really better than the other as it depends on your application where you are, what you doing with the solar panel, how much you want to spend.So, if you use the thin film panels, now that is a 15 watt panel keep in mind, this is a hundred watt and this is a hundred watt.The monocrystallines are more.
Efficient than the polys and more efficient than the thin film.The monocrystalline panel, 100 watt, will be smaller in size than a polycrystalline will be.Polycrystalline of the same wattage will be bigger.Now, thin film amorphous of the same wattage if it was a hundred watt will be even bigger, quite a bit bigger than a polycrystalline or monocrystalline, so room is a factor, say if you’re doing a roof or something and room is a factor for you, you don’t have much room, you definitely wouldn’t want to go with thin film.You’d want to go with.
Polycrystalline or monocrystalline.Mono will take up the least amount of room.Now, here’s another difference between these panels monocrystalline is really great for low light conditions over polycrystalline and by low light i mean, say if you live in the northern states or if you live in canada where the where it’s overcast quite a bit and lower light up in alaska, monocrystalline would be what you would want to use.They’re more efficient and work much better in low light conditions than poly does or amorphous.Which solar panel costs more.
Well, if we’re talking about a hundred watts and a hundred watts and a hundred watts, then monocrystalline will cost the most, polycrystalline will be cheaper than mono and amorphous, or thin film, will be the cheapest of all.Now, why is that well, the monocrystallines just simply cost more to manufacture.The cells are more even and this is a much more efficient panel than the polycrystalline and it takes more time to do the monocrystalline than it does to do a poly.Well, there’s nothing wrong with polys, but the way these are manufactured is just.
Simply cheaper to manufacture than the monocrystalline is.Now, the amorphous or thin film is absolutely the cheapest to manufacture.Monocrystallines are 10 percent more efficient over polys.Now, that number changes a little bit and you have to also keep in mind manufacturer.We’re talking about if these were all the same manufacturer of highquality panels, this could be 10 percent more efficient and actually this monocrystalline can put out four times as much power over the same size in a thin film amorphous.Now, if you’re concerned about aesthetics on your roof.
And you want uniform color in your solar panels on your roof, monocrystalline would be what you would use.There are color differences in polycrystalline and they’re not as uniform in color at all.The thin film amorphous, those are usually the same color and they’ve got a pretty uniform color.So if aesthetics is an important factor to you, you’d want to use monos.Economy is an important factor to you, using thin film amorphous is where you’d want to go.Efficiency of each one of these panels, now this number will vary also.
With manufacturers, but the mono’s efficiency is 15 to 20, poly is 13 to 16 and the thin film amorphous is 7 to 13 efficient.So there’s your efficiency.Life expectancy what do you expect to get out of solar panels the monos don’t really last any longer than the polys, they might last a little bit longer but now the polys have caught up and they last pretty much the same amount of time as the monocrystallines do.The amorphous thin film are the worst.They will live the least amount of time, their life.
Can be short.25 years on the mono, 25 years is what people are giving the polycrystalline and i’m not sure the years anybody gives on the thin films.Basically what that means is at the end of twenty five years, the numbers go up and down a little bit but they can lose 30 of their.10 to 30 of their efficiency.See, those numbers are all over the place.Everybody has their own opinion on that so i’m just gonna go on some of the different articles i’ve read as to how long do they last.
They say the solar panels can last up to 75 years, so i don’t know and that’s just what they say.Of course, they’ve got to be around seventyfive years first us find out.But fifty years, i guess, is supposed to be the life expectancy of solar panel and do they go dead at the end of fifty years that i don’t know on that question.There are solar panels that were made back in the 1970’s and i’ve seen a few of them and even the 1980’s and those guys said.
Their power output today is down 50, half of what it was.So out of a 100 watt solar panel from the 70’s80’s, they’re getting 50 watts out of today so that’s all i can tell you on their length, their longevity.For most residential use where you’re just a homeowner, most residential uses, those people really get polycrystalline.For the people that are really interested in, i mean, the highest efficiency and uniform color, you see a lot of the stuff on government buildings in states and that sort of thing, they get monocrystalline.The thin film.
Amorphous solar panel, i have to show you something here.Okay, to give ya the idea of the size difference this is a fifteen watt this is part of a 45 watt harbor freight solar panel kit i know you guys have seen them, they come with three panels like this.This is this is a 15 watt thin film amorphous panel, this is a harbor freight panel.Now you can size difference up against a hundred watt poly, okay, so it’s quite a bit of size difference here.Now a lot of people.
Run to harbor freight when they get shot coupons and they think, what a great deal, harbor freight solar panels, because they get all these cool lights and a little charge controller and stuff, but it is a horrible deal! it’s an absolutely horrible deal to mess with getting a harbor freight solar panel kit and let me tell you why.I was just at harbor freight myself and this is november 2015 the 45 watt solar panel kit from harbor freight 45 watt was $189 here in springfield, missouri.They’ll shoot you out a coupon for a hundred and fifty bucks.
It varies upanddown and depends on where you live.So now you’re talking about, with a coupon $150 for 45 watts.A hundred watt solar panel will cost you a hundred and twenty to a hundred and thirty dollars for a hundred watt, okay so you’re getting twice the wattage and a long lasting solar panel for the same money and that’s a lot.The other problem these harbor freight solar panels have is the charge controller that comes with them is usually only for 45 watts.So that little cheapie charge.
Controller that comes with them 45 watts.You can’t upgrade those at all.The problem that harbor freight is always had, unless they have changed it, is the wiring on the back of their solar panels is too small and it has always choked the power out of the harbor freight panels.So typically what people have done, and what you can even do yourself if you do have a harbor freight kit, is take this wire out of there and it’s usually like a 16 gauge wire even 18 gauge sometimes wire.
That’s out of the back of these, you can take this panel off and replace the cable that’s on your harbor freight panels with a 12 gauge wire and you’ll see an amperage increase out of that 45 watt panel kit.So my suggestion is do not buy the harbor freight solar panel kit unless that’s something you want for camping or whatever because, dollar for watt, it is a horrible value.It’ll go to $189 typical price, $189 for 45 watts or $130 bucks for 100 watts.These panels will last you.
Twentyfive years, these will not.I have seen a lot of these burn out in two to five years, burned out.It is a bad value and i’ve seen other people that have promoted these a long time ago when they first came out and later on they were sorry they did it.So we have a hundred and thirty dollars for a one hundred watt panel and you say yeah, but it doesn’t come with a charge controller.Well for 10 or 20 bucks, you can buy a 10 amp charge controller for a one hundred.
Watt panel and a hundred watt panel puts out 5 amps, you know, 5 point something amps.So pretty much you can get even a twenty amp little cheap charge controller for 20 bucks, 20 amp, alright so you can put three to four of these hundred watt panels on it.But anyway, a hundred thirty for a poly panel, hundred watter, 10 to 20 bucks for the charge controller now you have a hundred and forty or fifty dollars into this solar panel and charge controller.Compare that with $189.If you get the coupon and they sell it to you for $130$150, it’s.
Still a horrible deal.It is not a good deal at all, so stay away from the harbor freight 45 watt solar panel kit.We’re back to the panels and what i mean by 12 volt solar panel is that these aren’t actually twelve volt, they’re meant for 12 volt battery charging.When you flip them around the actual voltage is like 21 volts on it.That’s meant for charging a 12 volt battery.Well, i think that’s it for now.I don’t want to go any further into this except one more thing people always ask me, do i need diodes for my panel solar.
Panels come with diodes, they’re already built in you don’t need them.These panels don’t need diodes, the diodes are in this junction box here and this is what’s called mc4 connectors.That’s what a pair of mc4 connectors look like.I’ve already showed this in another tutorial but i’ll do it again.See down here, this one, the female is negative and this one, the male, is positive.All the ratings are on the back of a solar panel.Anyway, this is a typical one hundred watt solar panel and.
Why Should We Launch Solar Panels Into Space
This episode of dnews is brought to you by full sail university.This week the japanese aerospace exploration agency announced it wants to get solar power from space.I’m having flashbacks to disasters from simcity2000.Hello! i’m trace.Thank you for watching dnews.Back in the 1960s, american aerospace engineer peter glaser proposed launching solar panels into space, and beaming the power they collect back to the surface for our use.Since the late 60s the idea has been in a holding pattern mainly because of the expense and worries about maintenance and equipment, but thanks.
To recent developments in solar panel tech the japanese space firm jaxa says they can finally try it.The plan is ambitious at minimum and cost hasn’t yet been calculated, but jaxa is determined, and they’re not the only ones.The u.S.Naval research laboratory is also interested in spacebased solar.The reason everyone’s looking up, is because that’s where the sun sits! if we can put a satellite in orbit to collect the sun’s rays before the atmosphere filters them out, and without the worry of a cloudy day, that would be rad.The jaxa space based power system.
Or sbps will orbit 22,400 miles up, and if done to their specs, would completely replace a nuclear power plant by producing 1 gigawatt of electricity enough to power halfamillion homes.Their plan uses a 10,000 metric ton system, which is.Well pretty ridiculous.The largest rocket ever launched was the saturn v it took our boys to the moon and could only lift about 130 metric tons.Once the power is gathered, a converter in space will convert the electricity into a microwave beam not like in your house, literally waves of energy that are.
On the micro scale.Microwaves can be converted from energy at 80 percent efficiency, which means there would be some loss, but it would be pretty damn efficient about 48 of the power collected would reach consumers.Which doesn’t sound great, but it really is.To make sure the array is getting sunlight 24hours a day, jaxa plans to put mirrors on either side of the planet to reflect sunlight at the collector all the time.The japanese are announcing their plan so far in advance in the hope other countries.
Will gather and help realize the dream of solar from space.Once created, it could provide clean, unlimited energy anywhere on the planet, regardless of remote location.Here’s the kicker.It would cost about a trillion dollars.Which sounds like a lot, but it’s like 125 bucks per person on the planet in 2030.And that’s way more than you’re paying doe your power bill.Not to mention oil wars and all the pollution, ecological damage, mining and drilling that goes with fossil fuels.We’ve got commenting areaaassss, check them out and type your feelings on spacebased.
Solar so we can all talk about it! none of this would be possible without computers to run the system, and we need people to write the computer programs.Full sail university in florida offers courses to help train tech professionals by blending code and realworld experience.Students of full sail have handson access to technology on their first day, get a discounted laptop and all the software they’ll need to earn degrees in software, mobile and web development.To find out more and support the show go to fullsail.Edudnews! thanks.
