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.
