Product Description:

1. Structure of Monocrystalline Silicon Solar Wafer 125*125mm Description

A wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the

 fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells. The wafer serves as the substrate for

 microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation,

etching, deposition of various materials, and photolithographic patterning. Finally the individual microcircuits are separated (dicing) and

packaged.

Q:how to build a solar panel?
Search Yahoo Answers or the internet first, this question is common. It is possible to build a solar thermal panel, to heat either water or air. You can just search YouTube to see how people did it. Try searching solar water heater. If you build a photovoltaic (solar electric) panel on your own, it will only be good for demonstration purposes. The homemade type I've seen produces only microamps of current - not even enough to run an iPod. Be wary of sites advertise you can make your own panel for less than $200 (or some figure), and try to sell you the plans. This is the same information that is posed on other sites for free.
Q:How much energy would this solar panel produce?

Where are you located?
Q:electronics help solar panel?
[] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
Q:45 Watt Solar Panel -?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:What Size Solar Panel Would I Need?
I know that in Texas we wouldn't even try to run an air-conditioner on a generator without at least a 6,000 watt generator and we would prefer a 0,000 watt generator. The calculator on the Kohler website says it'll be 7,500 watts. At $5 per watt to install a solar photovoltaic system and assuming you also need to run it through the night and taking into account that an inverter can be as bad as 60% efficient, you're talking about $87,500 just to run your AC for 25 years. The first step in going solar is to significantly reduce your energy use. You're not going to maintain your current energy use on solar, at least not cost effectively. If you did want to run an AC on solar power, you may want to look at absorption air conditioning and use evacuated tube solar thermal collectors instead but don't expect it to be cheap and it usually only augments the use of natural gas in the absorption chiller.
Q:Why do solar panels burn out?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:i want to light up a building using solar panel what do i need?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q:Using solar panels to replace electrical wiring?
No. solar panels would not solve your problems and are usually not cost effective. Solar panels will not help to compensate for undersized electrical service. You would still have to upgrade the existing service. Once that is done you should have no problems and all the electricity you need would come from your power company. Have an electrician come out and do an inspection and tell you what all needs upgrading. Solar panels would save you money on the monthly power bill but the cost to install them would be higher than your savings. If it made economic sense to have solar power then everybody would be doing it. That's why you see very few houses with solar panels on top.
Q:What is the most efficient solar panel?
Of okorder.com/... , and shop the web for the best panels for yourself. p.s. I'd avoid amorphous silicon panels. They may be cheap, but they'll go bad or seriously degrade in just a few years. p.p.s. I'd also avoid internet guides that claim you can make your own panels very cheaply, if you'll just pay them $$ for the information. Those guides don't live up to their advertising.
