FAQ

my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP

leave the car in the sun for a few hours to see if it charges. if not, the panel is defective. get it replaced b4 the science fair

Alright my family and i are buying a new home in Bradford,Ontario, we we thinking about solar panels and had a couple questions:. how much are they each?2. how many will we need to power a single family home(4 ppl)3. where can we find them in ontario?4.how much money do they really save you?5.what kind of energy do they providfe you withand other basic info or a website i can check out would be great!thanks in advance!

the first person is absolutely wrong. A 200 watt panel is $000US. By the time you buy mounting systems, wire, inverters, electric panels, interconnects, labor and permits/inspections, the cost is about $7/watt. if you use 700 kw-hr (please look at the units, you use kw-hr NOT kw) per month that 24 kw-hr per day. in your area, a pv system will supply about 4 hours at peak production of the panels, so you will need 6kw in panels, that's about 30 panel or $42,000 in equipment.

i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?

An LED requires an electric current to power it. A solar panel can most definitely power an LED, but LEDs don't store any power themselves. And solar panels aren't designed to be powered, they are designed to generate electricity. Rethink your premise from the start. It is as if you were asking if the electric wires in your home or community would be powered by the light bulbs and appliances you use.

i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.

Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.

If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.

Solar panels do not wear out the way machinery does. The semiconductors used give up electrons by receiving photons, and do not experience a net deficit of particles. However, if you placed a heat source such as a heat lamp too close to a solar panel, you could damage the panel by overheating it, which would denature the semiconductors or cause damage by scorching or melting. The problem would be the heat, not the light. Solar panels do have a finite life expectancy, though it is several decades under normal circumstances. The panels will eventually become scratched, warped, and dented. The electrical conductors will eventually be broken by metal fatigue as the panels heat and cool on a daily basis. So they will die of old age, but they don't wear out in an electrochemical sense.

Solar panels can be used in areas with high levels of vandalism, but additional security measures should be implemented to protect the panels from potential damage and theft.

There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Yes, solar panels can be installed on a retirement home or assisted living facility. In fact, many retirement homes and assisted living facilities are recognizing the benefits of solar energy, such as reduced energy costs and environmental sustainability, and are choosing to install solar panels on their buildings.
