Utility offers deal for solar panels
Tuesday, September 25th, 2007Have a solar panel? Been thinking about getting one?
A new program through Santee Cooper would allow you to reduce your electricity bill or get paid for the electricity you produce if you use a solar panel.
The program, called net billing, works like this: Santee Cooper buys electricity from you, and you [...]
new solar panels
Wednesday, August 29th, 2007British researchers are developing thin-layer solar cells that may make it less expensive to use solar energy to power homes.
Durham University scientists are using materials such as copper indium diselenide and cadmium telluride to find an affordable and more sustainable way to make solar panels to convert light energy into electricity, the university said in [...]
Researchers Develop Solar Cell That Can Be Painted or Printed on Plastic
Saturday, August 18th, 2007Researchers at New Jersey Institute of Technology (NJIT) have developed an inexpensive solar cell that can be painted or printed on flexible plastic sheets. “The process is simple,” said lead researcher and author Somenath Mitra, PhD, professor and acting chair of NJIT’s Department of Chemistry and Environmental Sciences. “Someday homeowners will [...]
Roof Space Saving
Thursday, August 16th, 2007Have you estimated how much roof space you would need to have enough power for the whole house? The following info will give some idea about that.
The solar panel shown in that article contains 4 cells, and each of them can produce 0.45 volts and 100 milliamps, or 45 milliwatts. Each cell measures 2 inches [...]
Solar Distillators
Friday, August 10th, 2007In the old days, when the sailors sailed the seven seas, there was a big lack…of water.
Now people have once more used solar power and came up with solar distillators, which use suns energy to heat up any kind of water, including salt water into pure fresh water. No chemicals, no more salt… nothing but [...]
Solar Cookers
Thursday, August 9th, 2007In Africa, fuel for cooking is rare, and if not, is always expensive. But there is plenty of sun, and people have tried to adapt the sunlight to suit the Africans. Not solar panels this time but solar cookers.
There lots of solar cookers, with mirrors which concentrate the sunlight into one spot, others with black [...]
Solar power attic fans
Sunday, July 29th, 2007 Even a few days of unexpectedly hot weather, given the soaring costs of energy, can send even the best-planned home energy budget into a tailspin. Homes with air conditioning units have barely livable interiors, and those without them are simply unlivable. But there is a bit of hope, in the solar powered attic fan.
Attics, [...]
Solar heating systems
Monday, July 23rd, 2007Solar hot water systems use sunlight to heat water. Solar hot water systems were used extensively in the United States up to the 1920s until replaced by relatively cheap and more reliable conventional heating fuels. The economic advantage of conventional heating fuels has varied over time resulting in periodic interest in solar hot water; however, [...]
Solar Panels Creativity
Saturday, July 21st, 2007Think about all the things that use energy; practically anything: cars, boats, factories, planes, ships, helicopters, and of course homes: air heating, water pumps, wall outlets, stoves, fridges, computers, etc.
Imagine of most of these things using solar power — great, eh? In a few year’s time, solar powered cars would be quite possible. Even [...]
