  energy falling on the earth is given by the solar
  constant, but very little use has been made of
  solar energy

Uses

• Solar energy is used for heating water for
  domestic use, space heating of buildings, drying
  agricultural products, and generating electrical
  energy.

Inventors Of The Solar Cell

• Daryl Chapin, Calvin Fuller and Gerald Pearson of
  Bell Labs were not planning to invent a solar
  cell that would revolutionize the PV industry.
  There wasnt even a PV industry to revolutionize
  when their work commenced in 1952.

5
Cost

• The best current deal on new 50 watt solar panels
  is about 4.25 a watt--212 for a 50 watt panel,
  in quantity
• Other new panels of about the same size can
  produce 120 watts, but cost 700--5.83 per watt.

6
Buyers Of Solar Panels

• People in general that dont really like their
  heating system, many big companies, Factories,

Is it in Use now?

• Yes it is.
• We use it to power cars.
• We use it to heat homes.
• We use it to heat schools.
• We use it to heat company's.

When is it Useful

• It is very useful in the winter when its cold.
  (Solar Heating)
• It is least useful in the summer when it is hot.
  (Solar Heating)
• In the summer when you have lots of sunlight its
  more useful. (Solar Power)
• In the winter when there's not sunlight its less
  useful. (Solar Power)

10
Advantages-Disadvantages

• Advantages Its Clean, doesnt cost much when its
  started, renewable.
• Disadvantages Start up could be costly, you need
