Solar Energy?

1. Hydro power, Wind & Rain x Solar
2. 175 W/pe
3. ground- rather than on rooftop-mounted?

1. PV installed capacity will be expanded to 20GW
2. low-capacity heaters in 2003
3. Baoding new 800 MW solar cell production capacity
4. 2010 the 4th International Solar Cities Congress
5. All in all, Himin's production capacity at Denzhou amounts to more than 1 million solar water heater units per year
6. “China Solar City” with 5.6 million inhabita
7. Capacity:100-300 liter. Life span:15years. Freeze protection:-25℃. Product Feature High solar-thermal conversion and low heat loss
8. My cheap zero maintenance silicon PV panels installed two months ago on my home ( $4.3 / Watt all-in) achieve 15%, I could have purchased other China made models achieving 18% plus if I had paid more per watt, which I wasn't willing to do.
9. project’s price ($4.66 million) by the power output over 25 years (54.76 million kWh) and arrives at 8.5 cents per kWh
10.
11. 13% conversion efficiency is low compared to other concentrated silicon solar alternatives available on the market right now, that achieve 26%
Many experts predict a transition toward solar power as a primary energy source in ... By 2030, the country's annual installed PV electric generating capacity could .... That's an annual growth rate of 35% – not bad for many industriesReputable silicon panel makers were selling their products at around € 1.2 [US $1.19] per watt during the first quarter of this year, Chase added. The prices have gone up to about € 1.70 per watt since then because of a rush to build projects in Germany ahead of an anticipated fall of the country’s feed-in tariff in July, but the prices could fall back to the first-quarter levels or drop even lower over the next 12 months, she said.SolFocus’s showcase project at the Victor Valley College provides some insight. The public college spent about $4.66 million from a voter-approved construction bond and other funds for the 1-MW project.To calculate the levelized cost of energy, the college divides the project’s price ($4.66 million) by the power output over 25 years (54.76 million kWh) and arrives at 8.5 cents per kWh, McQuilkin said. The LCOE doesn’t include the operational and maintenance costs. The LCOE would go down to 1.5 cents per kWh if you include incentives that will be based on the amount of energy the power plant produces.SolFocus is using highly efficient cells of gallium arsenide on a germanium substrate, which can convert close to 39 percent of the sunlight that hits them into electricity (under high concentration). By concentrating the sun 650 times, each SolFocus panel can achieve 26 percent efficiency.
