Solar panel material

1. glass

 Its main role is to protect the power generation ( solar cells ) , there is a selection of light transmittance requirements : 1 ) must be high transmittance (typically 91% or more ) ; 2 ) super white steel processing.


2. EVA

 For bonding glass and power generation fixed body ( such as cells ) , transparent EVA material directly affect the life of components exposed to the air EVA prone aging yellow , thus affecting the transmittance components , thus affecting in addition to generating the quality of the components itself, the quality EVA lamination process on the component manufacturers is also very large, such as EVA plastic viscosity of non-compliance , EVA and glass, back bonding strength is not enough, can cause premature aging EVA, the affected component life.


3. Solar cells

 The main role is to generate electricity , the electricity is the main market mainstream film crystalline silicon solar cells , thin-film solar cells , both have their advantages and disadvantages . Crystalline silicon solar cells , the equipment costs are relatively low , but the high cost of consumption and cells , photoelectric conversion efficiency is high, the next generation in outdoor sunlight is more appropriate ; higher thin-film solar cells , the relative cost of equipment , but the cost of consumption and battery low, relatively low photoelectric conversion efficiency of crystalline silicon solar cells , but the effect is very good low-light , in the ordinary light can also generate electricity , such as solar calculator .


4. backplane

 Sealing, insulation , water ( usually with TPT, TPE , etc. ) the material must be resistant to aging , component manufacturers generally have warranty for 25 years , tempered glass, aluminum is generally no problem , the key lies in whether the backplane and can meet the requirements of silica gel.

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:how much power do i need from my solar panels?
Very simple. Look at your bills from the past year and calculate how much power you used and see what you need to cover that usage. How are we supposed to know how much power you use? Maybe you live in a bdrm trailer or a 6000 sg ft house with 20 kids. Oh and remember a few things. There is more to ' going off the grid ' than just solar panels. When the panels work depends a lot on your climate. They kind of suck on cloudy days or if you live in the artic with 6 months of darkness.Also , you need an area for the (not so cheap) storage batteries. Learn to live by cooking with gas or wood as hydro is limited , so is heat. How do you plan on heating your home /water/ refrigerators and freezers? Off the grid means a lot of compromise. Even the amount of time you can spend on the computer asking these questions. You may be limited to no more than hr per day. Off the grid also includes removing any electronic influence. No cell phones , tv (cable/sat) internet. Grow your own food and live off the land. The amount of solar panels you would need to maintain even a current lifestyle as most of us know it would probably require at least /2 acre and the cost would take at least 5-25 yrs to recover. You really need to spend more time into looking at what the cost versus return is. Like I said before. Look at what you use and see what it takes to get that from your panels. You will be shocked. Currently the panels are very good. But they cannot produce what the average home needs per day every day, they are support systems. Much like a fire place. Now they are nice to have and are very efficient. 50 yrs ago you used to toss in 2-3' logs about 6 around into the only heat source in your home. A fireplace. And it sucked more cold air into the house than the heat it produced. History has a way of repeating itself. This stuff was out almost a decade ago, they just didn`t have batteries then
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:how do buildings circulate energy?
The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:Maintenance of Solar Panel?
I don't know if the guy is right about cells burning out if they are covered. You should look on the Internet for insolation tables for your area to see the effective hours of sunlight. Then guesstimate the percentage of time the panels will be shaded. Those trees may make the solar thing a poor idea. He is right about the trees reducing you efficiency. If a panel is shaded about 0 percent, its output drops to close to zero. My panels are five years old, and I have washed them twice. There as been no noticeable dropoff in output.
Q:how to power a 400 watt heater with solar panels and batteries?
You could do that, but it would be an expensive way to go. If what you really want is heat, consider heating water directly with conventional solar water heaters, and storing it in a large, insulated tank. You can then circulate the water through a conventional radiator at night.
Q:I need help with solar panels?
Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
Q:how much do solar panels cost?
The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.
