Solar Energy News Thursday September 7th 2006
Desperately seeking silicon
In a world of silicon scarcity, many solar energy companies are trying to find ways to stretch, cut back on, or even cut out the traditional photovoltaic panel's main ingredient. Solar companies from around the world met in Dresden, Germany, this week at the 21st annual European Photovoltaic Solar Energy Conference and Exhibition, where several announced innovations that would allow panel makers to increase their production capacity. Midland, Mich. based silicon maker Dow Corning unveiled PV 1101 - a feedstock material that can be blended with solar-grade silicon to stretch the dwindling supply.
Solar power can be pricey
If solar energy can run everything from parking meters to pay phones and spacecraft to car battery chargers, why can't it power your home? And while we're at it, why can't we all harness the wind as an energy source? It's free, too. The reality is that renewable energy sources work but are among the most expensive forms of power on the market today when the cost of buying and installing the equipment is factored in.
Family Converts To Solar Power
Jack and Cheryl Hawkins have a new addition to their 5-acre ranch in Santa Clarita, a 72 photovoltaic solar panels rigged to catch the sun's rays from sun-up to sun-down. "The way these panels work, I can still get 40 percent efficiency out of the panels on a totally overcast day even if it's raining. So it's still going to put out juice. The PV panels convert sunlight to electricity using semiconductor devices called solar cells. The photovoltaic conversion process creates no pollution."
Solar Energy for the Poor
Photovoltaic electricity might one day be a profitable business, even in developing countries. While the biggest markets for solar power continue to be Germany, Japan, and the United States, some researchers said Wednesday evening that they soon hope to target developing countries. “There have been past failures,” said Bernard McNelis, managing director and co-founder of renewable energy consultancy IT Power, at the European Photovoltaic Industry Association’s industry forum Wednesday. “But the programs going on now recognize the failures of the past and plan to tackle the problems in a long-term, sustainable way. I think the tide has turned.”
Poor people get solar power
Solar power generation systems have been installed in the homes of 351 poor families in Phuket as part of a nationwide project to bring power to areas not yet connected to the main grid. Announcing this at a meeting at the Thavorn Grand Plaza hotel on September 4, Prawat Siripatrodom of the Provincial Electricity Authority (PEC), said that a further 100 householders have applied for solar power but were disqualified because they lack house registration documents. The PEC and district authorities will work together to try and solve that problem, K. Prawat said. He explained that the Solar Home System project has a budget of more than 5 billion baht from the central government, sufficient to install solar power in about 203,000 households around Thailand. “So far we have installed systems in 180,000 homes. The remaining homes are mostly in the North and the Deep South,” he said.
