How to Install Solar Panels Battery Banks for Solar Energy
Now we come to our battery bank for our Solar system. This one is made up of six volt cells combined in different ways to get the voltage we need for our individual inverters. We're going to be using the big Zantrax 1,000 watt this time, so we'll need two six volt cells, in series, to come up with that twelve volts. If you take your battery and connect a positive to a negative terminal that leaves you with a positive and negative terminal and you can get your twelve volts here. If you connect four batteries in series, positive to negative,.
You come up with twentyfour volts. And if you needed a fortyeight volt system, which is not uncommon, you'd simply expand and use more batteries. But for a twelve volt system we'll just use two. And, they're really the most dangerous part of the system. If you look down inside there, you can see a liquid and that liquid is sulfuric acid and will really seriously burn you and that's why we have a base here, Baking Soda, and if you get that acid in your eyes or in your clothing you can neutralize it with this. So, very.
Important to have this for safety. We can get a look at some of that acid here with the hydrometer, this is what you measure the actual specific gravity of the acid inside. And you can see we have several of these disks floating. We have about three disks floating with one at the bottom. So we know that this two batteries, or at least this battery, is about seventyfive percent charged. So, we're going to be very careful with that acid and stick this back here in our little cup. It's also important to note that the gases that.
Why Teslas Powerwall Battery Is Amazing
All of humanity just won a really important victory in our battle to lower the CO2 emissions that are causing climate change. Tesla CEO Elon Musk introduced the world to the Powerwall, a wallmounted battery for your house which aims to accelerate our transition to clean solar and windpower. Before the powerwall, there was no way to store the energy generated from the panels that capture sunlight on our roofs. So during the day they could give you the power you needed, but at night, you had to rely on the grid, which gets most of its.
Electricity from coal, natural gas, and nuclear reactors. There had been some early home batteries out there, but nothing that was nearly this affordable. But Tesla, which has built thousands of large, lithiumion battery packs for its growing electric car business, was able to produce a similar battery for buildings at a scale that dropped the production costs dramatically. The lowest capacity model will cost just $3,000. And this is the first generation of the productbefore Tesla's even completed building its massive new Gigafactory, or any real competitors have entered the market, events that will surely push the price down.
Even further, while increasing the energy storage capacity of the Powerwall. Here's how it works. When the sun is out, solar panels will power your house and charge the Powerwall at the same time. And when the sun goes down, this charged battery will kick in to meet most or all of your electricity needs until the sun comes back up again the next morning. This is gamechanging. More and more people will go completely offgrid. Every building whether it's a home, office, business, warehouse, factory they can all.
Install solar panels and some Powerwalls and instantly see their fossil fuelgenerated electricity needs drop significantly. Not every building will be able to go completely solarpowered, but most will get pretty close, especially as our appliances become more and more energy efficient. And it gets even better. The powerwall will be connected to the Internet and the rest of the energy grid. Here in Southern California, and most other heavily populated places, the electricity company charges us a lot more when we use electricity during peak timethat's in the afternoon and early evening when the temperatures are warmest and most of us are.
Home and still awake. The Tesla battery is smart, and knows when electricity is cheapest, so that's when it will draw from the grid to charge itself. And then, during peak time when you need electricity, the battery will power the house. Sometimes, you'll be able to sell back unused power to the utility company during peak time to even make a profit. It's basically going to make each individual building its own power station. Overnight, Tesla seems less a futuristic car company, and more like the man who inspired the company's name, a revolutionary electricity engineer named Nikola.

How Solar Energy Is Converted To Electricity Through Solar Panels
Sunlight is made up of tiny packets of energy, called photons. Every minute, enough of this energy reaches the earth to meet the world's energy demand for a whole year. Photovoltaic panels consists of many solar cells, these are materials made like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in the battery. As photons are absorb in the cell, their energy causes electrons to come free. The electrons move towards the bottom of the cell, and exit through the connecting wire. This flow of.

Top 5 Power Banks of 2015!
Hey guys AppsOnFire here and today I'm gonna be counting down the best power banks that I have seen this past year. This is the top 5 power banks of 2015. So first on our list is the ravpower 3200mah power bank with UV flashlight. This is pretty much your average mini power bank except for the fact that instead of the usual flashlight it comes with a built in UV light which is useful for a lot of different things. It is really good at catching stains that you wouldn't see with the regular eye. I found this fun to play around with at times.
But haven't used the UV light much. But still this power bank from ravpower has a solid design with the matte black finish and a special shaped ergonomic design that is different from most power banks. You get one smart charging port and you get some LED indicators to tell you how much power is left. Moving on to the second power bank on our list I have one with probably the best build quality out of all of them. The jackery giant plus has just an awesome build and a lot of power. It is packing a 12000mah battery and has two fast charging.
USB ports. The battery pack itself is not the thinnest but still remains light and compact. With an aluminum build and this much power, it is one of my favorite power banks. It also comes with three LED indicators as well as a flashlight. So this is one of the more traditional lipstick power banks. This design is probably the most popular design because it is very compact and you can fit it almost anywhere. If you search for portable chargers chances are that it is going to look like this one right here. Small chargers like this usually.
Come with 1 to 2 charges for your phone. This one comes with 3200mah. Anker is probably the leading company in portable chargers and that's because they are just very good at what they do and you know that with every product you get from them, you can expect quality. So this is actually one of the biggest power banks out there coming from a company called Avantech. This may not have the best build quality but it is packing a huge amount of power. You can probably charge two devices at least 5 or 6 times without even recharging.
The power bank and that is amazing. It is a bit bulky and heavy but it is definitely worth it if you are looking for the power. Again you get some LED indicators and you get a plastic design with a matte finish. Now finally we have my favorite power bank out of all of these and that is the elivebuy 10,000mah portable charger. It is my favorite because of its really cool two tone color and that it is packing a huge amount of power into a very thin package. I mean this is just a little bit bigger than my phone. It also.
Mini Digital Volt Meter Ideas
I've got this homemade power supply that I've been wanting to put a meter on for a long time and in the past I had choices like analog meters and the they look like this minus the control down here. As you can see it's just too big, they take up a lot of space and they are not all that accurate. and then there's this bar type but the bar type well frankly it'll also take a lot of space and to not all that accurate. So the other day.
These have been out for a while, but the other I found one of these Thought I would put it on here. Let me tell you a bit about them They are rather interesting, little selfcontained digital volt meters This is a 3wire system and what that means is that you power the meter with voltage between the red and the black It can vary a lot. This particular one is between 3 and 30 volts it operates And that is these 2. And the sensing is a between the black wire over here and the white wire.
And it will sense the voltage and that's what comes out on the readout, what's between the black and white wires and ths one they told me will sense between between 0 and 50 volts. Right now I'm running it on a battery pack but by simply touching the white wire on the red wire I can measure the voltage of the battery pack which is showing 2.9 volts. I can power it with 1 power and measure something completely different. I can show you and example of that with a quick and dirty volt meter. Also this is all.
Selfcontained very tiny you can see. I can mount it on the outside It's got little ears. I've got lots of space for it right here. It not going to be an issue With the 2 wire system it takes about 3 volts before the display cames on So it obviously will not measure anything less than 3 volts but with this one I can measure, well right now I'm getting zero volts The power is on so clearly I can measure measure a lower voltage than it takes to operate the display LEDs.
That is the benefit of the 3 wire system. I can read much much smaller voltages down to 0.1 volts in this case As an example of what you can do with these digital volt meter displays I taped one you could mount it permanently on to a battery holder, there are a couple of battieries in there turned it on and then just connect the common black and the sensing on to my target and 1.50 volts and that's correct for this battery So now I have mounted this digital volt meter on to my power supply.
Turning Salt water into Drinking water using Solar power
According to the Securing Water for Food agency, between 2000 and 2050 water demand is expected to increase 55 percent globally, meaning the number of people affected by water scarcity will continue to grow. By 2025, twothirds of the world's population could be living in severe water stress conditions. Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water and much of that area is not served by an electric grid that could run conventional reverseosmosis desalination plants.
To find solution for this drinking water issue in developing countries, USAID the U.S. Agency for International Development had run a global competion for Desal prize. The idea for the competition was to create a system that could remove salt from water and meet three criteria it had to be costeffective, environmentally sustainable, and energy efficient. The winners of the $140,000 first prize were a group from MIT and Jain Irrigation Systems. The group came up with a method that uses solar panels to charge a bank of batteries. The batteries then power a system that removes salt from the water through electrodialysis,.
That means that dissolved salt particles, which have a slight electric charge, are drawn out of the water when a small electrical current is applied. Using the sun instead of fossil fuels to power a desalination plant isn't a totally new idea. Larger solar desalination plants are being seriously investigated in areas where water is becoming a scarce resource, including Chile and California.But the current technology is expensive. The MIT team's this new desalination technology electrodialysis is comparatively less expensive. Both electrodialysis and reverse osmosis require the use of membranes, but the membranes in.
