how can you harness solar energy ? give and explain three methods.
Answers
Answer:
There are three primary technologies by which solar energy is harnessed: photovoltaics (PV), which directly convert light to electricity; concentrating solar power (CSP), which uses heat from the sun (thermal energy) to drive utility-scale, electric turbines; and solar heating and cooling (SHC) systems, which collect thermal energy to provide hot water and air heating or conditioning.
There are various methods for the harnessing the solar energy as mention below some methods
Explanation:
1. Solar Thermal Electricity – Solar energy used to heat the water and run turbines for the production of clean-electricity.
2. Photo-voltaic Systems – These panels made from different materials and when exposed to sunlight, use heat and light to excite electrons loose and create an electric current in a process called the photo voltaic effect.
3. Solar Water Heating – In this methods Solar panels terms as solar collector are used, they are usually have a rectangular chambers with multiple small tubes called flat-plate collectors, which circulate water or another fluid by means of this energy is transmitted to liquid and its becomes hot. This method widely used in hotels ,large offices and building.
