How to Install Solar Panels Thin Film Solar Modules
Now we have here a little different kind of panel. The latest manufactures have gone to what is called the thin film module where they are trying to use the smallest amount of the silicon. Which as it turns out is the most pure product and the most expensive. So with a smaller amount of silicon in the overall panel, one would hope the price would come down. This is a Kinoka Thin Film Panel. And it is designed to generate more like ninety volts DC and that is better off used in larger grid tie systems. Where as these smaller more.
Lower voltage forty volt panels are better for battery charging systems which is what we are putting in today. And as we are seeing here this Kinoka panel is rated at sixty volts or sixty watts. Excuse me ninety volts DC at only one amp. So we have got a little different style of electricity being generated. It still comes out the same way. Through a junction box and through very small gage wires. It is just used by the charge controller in a different way. So this Kinoka panel which is rated now at ninety volts at one amp DC.
Printing Australias largest solar cells
Dr Scott Watkins We're really pleased to commission what is now Australia's largest facility for printing thin film solar cells. This equipment that has been purchased over the last few months and commissioned in our labs here in Melbourne will enable us to print A3 size solar cells. We've rapidly scaled up making our devices from fingernail size in the lab to A3 size devices that are fully printed now. And at this size we're definitely up there with the best in the world. In the short term we're looking for applications in consumer devices.

In the short term we're looking for applications in consumer devices.
And small integrated electronics. In the longer term we see these materials being able to be coated onto buildings, into windows and on roofs to provide power in a wide variety of locations and circumstances. Dr David Jones One of the advantages of the technology that we're developing is we're actually using off the shelf printers, printers you can go out and buy. And therefore we're using a screen printer, one that you would normally use in label manufacture or screen printing of tshirts or other things. So these are commercially available printers.
So the outcome of this will be prototype demonstrators that we can give to a number of people to examine what the capability of the new technology is. Dr YiBing Cheng I do see this project is a very good example of a collaboration involves both, involves the CSIRO, Monash University and Melbourne University. And that we have a very close collaboration with people working each others laboratory and we have regular meetings every two weeks. We do see that through this kind of collaboration and we can build up a critical mass and.
Are Solar Panels Going To 300 Watts Soon
Right now solar panels are around the 200 watt range. Are they ever Going To 300 Watts is a question I asked John Shaw project engineer of Bella Energy. Absolutely, any manufacturer can do that right now. You shouldn't really look at how many watts a panel has rather how many watts per square foot can be attained. Behind you is a Sanyo 200, if you increase the foot print of that panel by 50 it is a 300 watt panel. The reality is what you need to be looking at to measure the level of progress of the.
Technology is how many watts per square foot. Instead of thinking will there ever be a 300 watt panel surely there will be even next year. To get at the point of your question is do you ever think we will be ever to achieve a 300 watt panel in 15 square feet And yes, I do. Right now standard efficiency panels are in the ballpark of about 12 watts per square foot, it ranges from 10 to 13. Standard efficiency panels Evergreens, Sharps, Kyocera, Shot , Suntech etc. Keep in mind this is the residential affordable panels, NASA works with panels that are about.
30 watts per square foot but you are talking a million bucks a panel. Then there are high efficiency panels of the ones we know of are SunPower and Sanyo. And Sunpower and Sanyo are approximately 15 watts per square foot. Both are very good products. Sanyo I believe has a little bit of an edge because they has an amorphous or thin film rap around the silicon cell which allows them to maintain high production in high heat. One more reason and I will tie this in. The Sanyo's are shipped with a minus 0 and a plus 5 percent so when you buy a 200 watt.
Sanyo panel you will get hypothetically in standard test conditions 75 degrees at sea level you will get 200 watts or up to 210 watts. All other panels including specifically Sunpower are or 5, so you could buy a 210 watt Sunpower cell and it could actually perform at 199 watts where you could buy a 200 watt Sanyo cell it could perform at 210 watts, but no less than 200 watts. So that and the fact the Sanyo's will out perform Sunpower apples to apples same azimuth and pitch in high heat because of this amorphous or thin film rap 10 in high heat peak days.
Stanford Start.Home Solar Panels
We decided to go with thin film. We liked that it was a pretty new technology that's actually getting better and better. There's a lot of great things about it. First, it's a lot cheaper than monocrystalline and it's also uses a lot less material. It's just a thin sheet of glass then, then the semiconductor layer. And so we really like that about these panels. And with a onthegrid system, like our house, you're actually selling electricity back to the grid. And then the great thing about it is that you produce the.
Most PV energy, photovoltaic energy during the day, when the sun's out. And that's actually when you would pay the most for it from the electric company. And so you're selling it back at those critical peak demand times, reducing the overall load on the system. We're using a standing steamed sheet metal roof, and it has these ridges in it so that you can actually use these clip products and just attach the, the PV panels to the roof. So that really reduces the amount of time it takes to install these PVs.
TE Connectivity SOLARLOK Micro Junction Box Introduction
My name is Greg Paukert and I'm a product manager with TE Connectivity and I'd like to introduce a new product in our 2rail product offering that typically gets used in our thin film industry. And what I would like to talk about first is the ability for our contacts to be either welded or soldered. And one important feature now and benefit to you as a customer is that on our contact tabs we have now solved the UL issue of mechanical strain relief support when you solder. So by having that feature will allow you then when you submit you product to UL for your.
UL submission to 1703, that will give you a good chance at passing. The second important feature on ours is this area here in the aperture area we have an aversion for potting or nonpotting. And the advantage for you there is that gives you a choice in your manufacturing processes of which one you want to use without have to change the profile format of the junction box body itself. The last important feature that we have on this is our wire entry seals, and the wire entry seal area here have been designed as a low cost but very robust system where we.
How to Install Solar Panels Solar Energy Change Controller
Now we'll get to know our charge controller. Today, we'll be installing a TriStar Charge Controller. This is pretty much standard device. It takes the power from the solar panels on the roof, and regulates it down to what our batteries can safely accept. It keeps track of it, and will output through these connectors, to computer controls, or monitoring systems. This is a fairly basic one, pulse wave modulated type. They now make maximum power point tracking charge controllers, a much nicer upgrade, and they are possibly $500, so you can make.
Your choices when you're starting your system. Start small, and add nicer components as you need them, so once you get the cover off of a standard charge controller, you see ports for your battery inputs, your solar inputs, and this one even has some DIP Switches that can be used to reconfigure this device, for different battery voltages. We can have a twelve, twenty four, or forty eight volt battery on this. We also have some multiple colored charging lights, to tell you when we've got power, when the batteries are needing charge,.
How to Install Solar Panels What is a Solar Panel
Well, today we are installing a small solar system on my personal residence. And we are going talk a little bit about what a solar panel is. This is of course a solar panel. A combination of silicon glass and aluminum. Precision components made in a factory. And able to take the photons coming from the sun and change it directly into electricity. Which then can be used any way we use electricity. So with our solar panel, there's lots of different kinds of solar panels and they are all designed for a little bit different applications. This.
How to Install Solar Panels Solar Panel Cable for Transferring Electricity
Alright, we've got our fat wire going over to our twelve volt batteries which we have saw earlier and will revisit again in a minute. This is a somewhat resistant low voltage landscape cable in size eight gage. So, we've got quite a bit of current carrying ability here and let's hook it up to our charge controller. We've got extra long wires here. This is eventually going to go in the laundry room because it's not an outdoor rated device. But, it's so pleasant to work out here in the sun, here we are. So now we've got our wire. The negative.
Is marked in white, as we know white is always the negative in this case. So, we'll take our positive wire over to the red connection inside this charge controller. And, here's our red connection and our nice fat battery wire going into it. Snug that little puppy down. It doesn't have to be terribly tight we're only talking ten amps, or charging here, so we're not really snugging these down. And, of course, we've got a common negative also going to the battery negative position inside our charge controller. We're back up on the.
Roof here and we're going to make this last negative connection, which is a white wire in this case. White is negative in DC systems or neutral in AC systems is a fairly. So now we're going to make our neutral or negative connection in this case with the white wire. Give it a good solid twist with our linesmen's and then add other wire nuts on top of that. Give it a little wrap of tape just to keep the weather out. There's other ways to make these connections. If it was.
