Solar Energy?

We Answered:

In order to figure out how much "load" your house is going to need, you'll need to add up all the projected electrical use that your future home will consume. You'll need to add up things like the fridge, washer, dryer, dishwasher, water heater (could be solar), TV, computer(s), all other misc electronic stuff will really suck up the power. Don't forget about the lights-think LED or compact flourescent. Also-think about adding more insulation than that which is required by your local building codes. A high-effeciency HVAC system will also help curb the electrical usage.

Who else uses solar energy?

We Answered:

Most countries in Europe make some power with solar panels. Japan and India do too. I use solar energy to heat my home (big double paned windows) and grow my garden.

Heather Said:

Is there any thermal power plant that uses solar energy converted into energy?

We Answered:

Yes!....and NO its not true!

A new 12 MW power plant was just put online last year in June. It is located just outside Phoenix, AZ, and it provides all of its power to Sempra Energy in San Diego for distribution to all those power hungry folk in the so-called nation's finest city. Go to the Sempra Energy site and check it out...its in their news releases.

Sam Said:

Solar energy uses what types of cells to convert the suns energy to electricity?

We Answered:

Photovoltaic Conversion

Uses sheets of special materials to create electricity from the sun. "Photo-" means "light," and "voltaic" means "producing electricity."

A “cell” is a device that produces electricity. An example of an electrical cell is a flashlight battery. Photovoltaic cells produce electricity when they are exposed to light. They usually consist of panels. The panels contain two layers of different materials.
