Solar power project

  1. 1. Solar Power By Zach Amaral
  2. 2. What is Solar Power? • Solar Power is the conversion of sunlight into electricity. • It directly uses photovoltaics (PV) or indirectly uses Concentrated Solar Power (CSP). • CSP uses lenses, mirrors and tracking systems to focus a large area of sunlight into a small beam. • CSP's were first developed in the 1980's.
  3. 3. • The concentrated heat from a CSP is used as a heat source for most power plants. • PV's were invented to be used for small and medium sized applications and still are. • Some examples of PV's are calculators, microwaves, and radios. • PV's are an important and inexpensive source of electrical energy. • PV's covert sunlight into currents by using the photoelectric effect.
  4. 4. How Solar Power Works • Solar panels convert the sun's energy into electricity. • Then a controlled device converts the electricity so it is able to power electrical items in your house. • The electricity then passes through a breaker box which distributes the electricity into your house. • Then all items plugged into electrical outlets have power.
  5. 5. History • 1767- The first solar collector was created by a Swiss scientist named Horace-Benedict de Saussure. • 1839- A French scientist named Edmond Becquerel discovered Photovoltaics which was a huge milestone at the time. • 1916- The scientist Robert Millikan found experimental evidence on the photoelectric effect. • 1947- Solar Power started to become more popular in the USA after the Second World War. There was a huge demand for Solar Power from the people. • 1958- Solar Power was used in space to power things such as satellites and space stations.
  6. 6. • 1981- Paul Macready made the first solar powered aircraft. The aircraft flew from France to England. • 1982- The first solar powered car was made in Australia. • 1999- The largest Solar Power plant was made at its time producing more than 20 Kilowatts. • 2012- There have been record breaking solar plants in China and India.
  7. 7. Pros for Solar Energy • Solar power itself is free but the equipment needed is not. • Does not cause pollution. • Can be used in remote areas. • Many everyday items are powered by solar power. • Solar energy will never end unlike other types of electricity. • Solar Power can be installed on many rooftops so you don't have to find the land for solar power placement.
  8. 8. Cons for Solar Energy • Solar power only works in daytime when it is sunny. • Solar panels, collectors, and cells are relatively expensive. • Solar power stations are very expensive and do not match every single power station. • In countries that have unreliable climate, solar power would be an unreliable source of electricity. • Large areas of land are needed.
  9. 9. Cost of Solar Power • Depending on the location and the design, the typical installation rate is 3-7 kilowatts and costs between 18k and 40k. • All of the equipment costs take up 45% of the final price. • Solar Panels(4.5k-12k), Power Inverter(1k-3k), mounting hardware(800$-2k), and Wiring(1k-2k). • Installation and permitting costs take up 25%. • System Installation(2k-4k), and permits and fees(3k-6k).
  10. 10. • Sales, marketing, and operational costs is 30%. • Monitoring(1k-3k), maintenance and repairs will depend on the part that is needed to be fixed. • Additional operational and overhead costs is 4k-9k.
  11. 11. Solar Power in British Columbia • Solar Power in BC is growing very quickly because of the locally developed leading edge technologies. • BC's best solar energy resources are located in the northeast and southern part of the province. • BC is trying to have more of the province use solar power. This is an example of a solar photovoltaic trash compactor. These are found in Victoria and Vancouver.
