Q:What ever happened to solar powered panels?
I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.
Q:Solar Panel questions...?
Just think about it and don't do it unless Ontario and the Utility companies give a huge rebate. Forget tax credits. Solar voltaic panels generate electricity...it will take more than 20 years to break even...assuming they last that long. Solar panels that generate hot water may be OK but will take about 0 years for a payback.
Q:How much would solar panels cost for these?
They would cost quite a bit but the user would likely be eligible for some energy credits from the power company and their cell phone carrier which would bring down the costs
Q:How many volts does an average solar panel produce?
2 volt and 24 volt are both common sizes. They are rated in voltage and watts. So you add the watts of the panels and buy enough to produce the amount of watts you need. For example, if you need 400 watts of power at 2 volts, you would buy four 00 watt 2 volt panels and connect them in parallel.
Q:Which spectrum of sunlight generates the electricity in a solar panel?
I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.
Q:How energy-productive are solar panels, compared to natural gas?
Solar thermal in commercial applications is more productive than natural gas, taking in consideration the sun must be out. the reason being is when natural gas is exposed to a heating element(boiler, hot water heater) it loses efficiency. lets say solar thermal can produce a therm of hot water, but that would equal .2 therms of natural gas using an 80 percent efficient boiler. solar being close to 95 percent efficient. No boiler can do that. now when the sun goes down, fossil fuel can beat electrically stored energy, not stored steam energy in a thermal plant for example. but that all depends on efficient steam generators.
Q:how much does solar panels cost for you home?
Depends on the size of your home, how many appliances you want to run at one time, and how much sunlight you get because all of that determines how many panels you need and how many batteries you need to install. I checked into it earlier this year and it was going to take almost 25 years to pay for itself. They aren't cheap.
Q:Does making solar panels cause more pollution than they take away when used?
It depends on what type of pollution you are talking about. Some of the newer cells that don't use silicone are made with dangerous chemicals that are just dumped into the local water supply when made in China or other places with no real environmental controls. No matter how much carbon free energy the cells produce they will never clean up the mess people made when building them.
Q:What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
325 mAh+ losses so maybe 3.2Ah to 3.5Ah.
Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
