1. GMM Solar Energy by Rob Smith GMM Committee on Climate Change

2. Solar energy is the world's most important energy resource. But the balance of absorption and radiation is critical.

3. The energy available from the sun can suffice for our needs. We can make use of it from wind-power and solar collectors.

4. Solar installation of a GMM member

5. Two grid-tie DC-AC inverters

6. A sunny day, 2026 watts, January, 2012

7. Power: 32 Solar Photovoltaic Modules @ 190 Watt=> 6000 Watts Energy: 6000 Watts x 90% efficiency x 3.5 hours / day=> 19 kWh/day Cost: $1.65 per watt 32 Modules x $315/module =>$10,000 Electronics & wiring$10,000 Installation$10,000 ----------- $30,000 Federal Tax Credit (30%) $9,00----------- Total after credit$21,000 Payback: At $0.15 per kWh: 19 kWh / day * $0.15 / kW=> $2.85 / day $21,000 / $2.85 / day=> 20 years Longevity:30 years or more

8. Power: 32 Solar Photovoltaic Modules @ 190 Watt => 6000 Watts Energy: 6000 watts x 90% efficiency x 3.5 hours / day=> 19 kWh/day to Power Grid 19 kWh / day x 365 days / year=> 7000 kWh / year Global Warming Savings: 1.9 lbs CO 2 per kWh generated (US average) 7000 kWh / year * 1.9 lbs CO 2 / kWh=> 13,300 lbs CO 2 /year => 6.65 tons/year CO 2 saved ! Over 20 years:=> 133 tons CO 2 saved ! => more than weight of house !
