Solar energy : 

Solar energy Every day, the sun radiates an large amount of energy- called solar energy. It radiates more energy in one second than the world has used since time began. Solar energy can be used as a source of heat and light and can be used to generate electricity.

Solar water heater : 

Solar water heater Solar energy can be used to heat water. Heating water for bathing, washing, dishwashing and for cloth washing. This is all through solar collector…

Solar energy as electricity : 

Solar energy as electricity Energy from the sun can be used to make electricity directly with photovoltaic panels or indirectly using concentrated sunlight to heat a liquid, which produces steam to turn electrical turbines. Concentrating solar plants can be built to store heat and deliver power for several hours without sunlight.

Power plants and their capacity : 

Power plants and their capacity SOLAR THERMAL POWER PLANTS 10 MW Solar II Engine System, Experimental Power Plant, California 25 kW Dish/Stirling Arizona 350 MW Parabolic Trough Power Plant, California

Slide 10: 

1900 heliostats, each 20 ft by 20 ft. A central 295 ft tower. It produces 10-MW solar power. Capital cost is greater than coal fired power plant, despite the no cost for fuel, ash disposal, and stack emissions. This is One of the way to reduce cost is to use the waste steam from the turbine for space heating or other industrial processes. pollution free, indefinitely sustainable.

Charging time of the battery of the Solar Tablet (for 1500 mAh battery): Solar energy = 6 hrs Wireless charging . Slim and light for out door activities.

Parabolic Dishes and Troughs : 

Parabolic Dishes and Troughs Because they work best under direct sunlight, parabolic dishes and troughs must be steered throughout the day in the direction of the sun. Collectors in southern CA.

Contribution of solar power : 

Contribution of solar power Global power consumption is estimated to total 150 trillion kilowatt-hours in 2010. Nearly half of that was produced by coal, while solar power contributed less than 0.1%. In Europe, nearly 92% of total solar power capacity is accounted for by just Germany and Spain. In July 2009, India unveiled a $19 billion plan to produce 20 GW of solar power by 2020. Under the plan, solar-powered equipment and applications would be mandatory in all government buildings including hospitals and hotels.

life : 

life Average 20-30 years Efficiency of solar cells is 30 % and it decreases 1% per year. Research on manufacturing and output efficiency and recycling ongoing. Payback or energy break even - 15 years.

cost : 

cost The cost of solar installations has fallen in recent years, but remains high, partly because demand continues to keep pace with supply. And like wind farms, utility-scale solar photovoltaic and concentrated-solar projects also require additional transmission connections.
