What is solar energy?

• a) Solar power is harnessing

the radiation from the sun and using

it as an energy resource. • b) Sunlight hits the silicon cells in the solar

panels and excite electrons to form an electron current.

• PV, or photovoltic, refers to a unit of electrical force.

Solar Thermal Power Plants

• The power plants generate electricity using the heat from sun to heat water and produce steam that is used to power the generator.

Solar Power Advantages• It is a renewable resource.

• Solar energy is a non-pollutant resource.

• Solar cells last a long time.

• Money will be saved in the long run.

Solar Power Disadvantages

• Equipment is very expensive at first.

• Space is needed to install solar panels.

• Only useful when the sun is shining.

• Need to be in a place with little obstructions.

Where is solar energy most accessible?

•The map of the United States shows the amount of kilowatt hours of solar energy potential per year for a kilowatt of solar installed.

•The map of the world shows the average daily solar radiation measured in watts per square meter per day.

Benefits

• It saves you money because solar panels are used to convert the suns energy in electricity.

• It will cut your carbon footprint.• The price of Solar Panels are approximately

$30-40,000 for a single family house.• It would take 5 to 8 years to make your

money back.• The power company may pay for your extra

electricity. It depends what company you have. Some companies will send you a check for every $25 mark.
