Q:Can someone tell me about solar panels for homes?
Solar panels produce low voltage direct current electricity. To be used in a home that electricity must be stored in batteries and converted to 20-240 volts 60 hertz AC (alternating current). And its frequency must be synchronized to the electricity supplied by the power company. A 00 watt solar panel produces 00 watts of power, enough to power one 00 watt light bulb. To generate enough power to power a home, the solar panel must be capable of producing at least 500 to 2000 watts per hour (.5/2.0 KW/hrs) And you're quite correct, it's an expensive proposition to install a solar panel system... and it should be installed by experts.
Q:What is the difference between solar panels and light panels?
The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.
Q:How does solar panel help/affect the economy?
sounds like a homework essay question to me
Q:solar panels for my home.?
Either you, or someone else, asked this same question yesterday, and the answers given were that it is not possible for us to answer it. The costs depend on where your home is located, what prevailing local labor rates are, how difficult it is to get the equipment to the site, etc, etc. I think one of the answers was that for a 3 bedroom, 2 bath house the cost for all the necessary equipment listed would be in the neighborhood of 20 to 30 THOUSAND DOLLARS. I think that was an underestimate, and that it could be 40 to 50 THOUSAND!!!!! The answerer also pointed out that due to the exorbitantly high costs of the technical equipment that at this time the equipment will wear out BEFORE IT EVER CAN PAY FOR ITSELF IN SAVINGS for on the grid electricity. I agree with that. You need to discuss your wants with 3 or 4, even 5 or 6 LOCAL ELECTRICAL CONTRACTORS to get a reasonably accurate estimate of the costs!!!!!!

Q:What are your opinions on solar energy?
I have had my system for almost a year and love it. I got a 3.74 kwh/dc system, my highest electric bill was $35 in the dead of winter and last month was $6.. I paid $6K for the system and was told I would break even in my 6th year, that was factoring in a 5% annual rate increase. In my area the last few rate increased have been well over 5% and they are talking up to 2% next year. Just keep in mind the amount of energy you use will determine how large of a system will work best for you. My system is tied to the grid, so I don't need a storage system. My utility has net metering, so I sell them my excess during the day and buy back what I need at night.
Q:Is it worth installing solar panels on a house that has no South-facing roof?
The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.
Q:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
