Dear Friends, I am very much worried about Global warming, So to contribute something for reducing Global Warming I have decided to use Solar Panels. Can anybody tell me what is the price of these Solar Panels and why people are not using them when they are environment friendly. What are the Pros and Cons of these Solar Panels?
here's lot of articles about the questions you just asked about solar panels, enjoy renewableenergyarticles.blogspot....
Solar panels are not environmentally friendly. They are expensive and inefficient. Dangerous chemicals that never break down in the environment are produced in the manufacture of solar panels. Their environmental footprint is larger on a per kilowatt basis, than conventional modes of electricity generation. And, because of their unreliability, they have to be backed up by conventional sources. Well-intentioned, but gullible, people the world over have convinced themselves that solar power is our salvation. Nothing could be further from the truth. As an example, check out Margaret Wente's recent column in the Globe Mail after Ontario's recent decision to go green. Also check out George Monbiot's critique of the UK experiment.
In the US and western Europe, the average cost to install a solar system.....panels, wire, battery bank inverters and all of that is $5 ( five) US a watt. ( One panel, 2 x 3 feet putting out 75 Watts costs $700-800 US ) Mos American homes use about 000 kilo Watt hours of electricity a month.. oking, heating, cooling, refrigeration, water lights and all that. that is 2,000 kilowatts a year. A solar panel system would therefore cost $60,000 US to install. That is WAY beyond almost everyone's means, which is why the US and Europe is not covered in solar panels. There is also the amount of sunlight per day and the height of the sun in the sky. There is a formula to figure out how much usable sunlight a day you get; the further north the less......and that number averages out to about 5 hours a day year round. So back to the 000 kW a month.......30 + kWh a day.......in 5 hours a day you have to generate 6,000 watts .... divide by 75 watts a panel = 35 panels x 75.00 per = 25,000 $ US plus wiring, batteries and all that........
A 35 Watt Solar Panel cost between 400 and 500 depending on where you make the deal. I live full time in an RV and I get all my electric from the Sun. I am sold on solar but I move around to places, according to the season, where I will have full sun most of the time. I also have a small generator as a back up but rarely use it. The amount of direct sun and angle of the panels will determine how efficient they are. For some one living in an apartment with only a few hours of sun then solar would not be good for them.
Solar okorder / And thin film solar panel power stations are about 50-60% cheaper now than solar power was in 2000. But they're still not economic in most places. Mike K's claim that solar panels produce more pollution than 'traditional' power is wrong. Coal is over 900g CO2/kWh, plus loads of pollution. Gas is ~400g CO2/kWh.
