Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
Q:How do you set up 30w solar panel?
With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
Q:Solar Panel Efficiency?
When it exposed to light, it starts generate electricity. Now the 200W written on panel is not its all time power. Its Watt Peak (200Wp) , it means when sun is at peak. it is around PM - 3.30PM daily in India(plane area). And panel never give 200w for more than 5 years, the efficiency reduced up to 0% at completion of 5 years of panel and 20% up to 25 years of life of panel.
Q:How do you make a homemade solar panel?

Q:How to build a solar panel for lighting/heat source?

Q:solar panel in a grid tied system?
I just costed an 85W panel I found online as paying back in 30 years. And that's without the inverter. If you want to do it to save money, look on surplus sites for chipped cells and make your own panels. You can then get the pay back time down to about 5 years, even with the 9.60/kWh price here, which is lower than many places.
Q:How to make 2V 4.5A solar panel from solar cells?
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
Have okorder.com . It may extremely teach everyone!
Q:I would like some info on Solar panels and Wind Generators...please?
I okorder.com... to size a system for your home. There is a link on the page to a world solar insolation map so you know how many sun hours you have per day on an avg. Should not take you more then a half hour to get a good idea of what it will cost you and which package system should work. Good luck on going green and don't let the Oil and Nuke people bring you down. They are just looseing money when you make your own power and their nuke power plant goes off line and not replaced. Some one above said solar cost more.. That is not true. I don't know about other countries but here the cost of living is about 3.5% per year so it is compounded each year. Then there is the rise in fuel cost which is 6.5% per year which will increase. But think about it you are buying 30 years of electric for 34000 dollars. If your electric bill was at current prices 00 dollars a month you would pay 36,000 dollars in 30 years. Now add in the 3.5% cost of living compounded each year for 30 years and the fuel increses . You will pay the public utilie 00,000 in that time frame
