By rss@youtube.com (Elzon1) CoolEarthSolar.com has a patented idea for inflatable solar collectors that are much cheaper than polished mirrors to concentrate sunlight onto Photovoltaic chips. Their design is 400x cheaper than polished aluminum mirrors, will withstand 130 mph winds, lasts a year, repairs with t...

By rss@youtube.com (LandmarkMediaInc) Solar Power is part of a Five Part Series: Solar power is defined as the energy we produce by converting sunlight into heat or electricity. It is one of the most abundant and affordable sources of energy available. However, it is difficult to harness and impractical in some parts of the world....

By Andrew Liszewski A built-in solar panel will fully recharge the battery in about 8 hours (in full sunlight at 25 degrees celsius) or it can be plugged into AC and recharged in just 4 hours. The whole idea of the lamp is to provide a highly affordable and easy to use light source for developing countries and low-...

By Chris Scott Barr As long as you don’t need fresh batteries on a daily basis, this little charger should do the trick. With full sunlight, you can recharge a set in just two days. However, if it is indoors getting 2-3 hours of sunlight each day, it might take more like 5 days. My biggest complaint with this product...

By Mike Millikin Solyndra’s panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. Solyndra’s panels perform optimally when mounted horizontally and packed closely toget...

By Mike Millikin The STEP (Solar Thermal Electrochemical Photo) process fundamentally captures sunlight more efficiently than photovoltaics by using the full (UV, visible and infrared) sunlight. More than 50% of solar energy is captured and used. Conventional photovoltaics lose much of the visible...

Sanyo HIT solar panels already had the highest efficiency of any solar panel for the home solar power market. With recent refinements, the company says it has achieved a conversion efficiency of 23.0%; that is, 23% of sunlight hitting the panel cells ...

The multicrystalline solar cells inside each panel can convert 16.5 percent of the sunlight that hits them into electricity, the company said. Last year, Toyota talked about using solar power to run some of the on-board electronics for Prius, ...

By Mike Millikin The Solar Hybrid model joins three other Husqvarna Automower battery-powered units. The Solar Hybrid mower has a maximum working area capacity of 2,220 m2 (0.65 acre). The size of the area mown by the Solar Hybrid mainly depends on the available sunlight, but also on the condition of the bla...

By Eliot Phillips In conclusion, [script] stated that he was happy with his experience, but that it was still impractical to use the portable panel in anything other than direct sunlight.        The 25th Chaos Communication Congress is underway in Berlin. One of the first talks we dropped in on was [script]...

By Mike Millikin An untreated silicon solar cell only absorbs 67.4% of sunlight shone upon it. From an economic and efficiency perspective, this unharvested light is wasted potential and a major barrier hampering the proliferation and widespread adoption of solar power.

By Mike Millikin Using a volatile electrolyte, DSC technology has delivered efficiency of up to 11.0-11.3% measured under the standard air mass 1.5 global (AM 1.5G) sunlight—about half that of the best silicon solar cell. [AM 1.5G is the intensity of insolation equivalent to the sun shining through the atmos...

By TravelGolf.com - Dave Berner Do you wear sunscreen on the golf course? You better, says Dr. Beth Lang, senior director of the Coppertone Solar Research Center. “I think people are aware of the risk, but I think golfers are particularly at risk because of the amount of time you’re in direct sunlight,” Lange says. “That fou...

By Mike Millikin Choosing the right semiconductor is also critical to making carbon dioxide splitting practical say the researchers.  Semiconductors have bands of energy to which electrons are confined.  Sunlight causes the electrons to leap from one band to the next creating an electrical energy pot...

By Mike Millikin Ascent Solar produces thin film solar cells by applying a layer of copper, indium, gallium and selenide (CIGS) to a flexible foil that is encapsulated in a protecting material. The resulting solar cells are extremely thin. The active layer that converts sunlight into electricity is no mo...
