Sun create two types of energy. -Light and heat.Plants use theese energy for Photosynthesis.We can convert these energy to Electric energy.
Solar energy meanse Converting Sunlight energy to Electrical energy.Photovoltaic cells are used to convert sunlight into electricity.
Usage of solar energy
Solar panels are devices that convert light into electricity. either directly using photo voltaics (PV), or indirectly using concentrated solar power (CSP).
Photo voltaics (PV) convert light into electric current using the photoelectric effect.
Concentrated solar power systems (CSP) use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.
How much electricity will get from a solar panel
The amount of electricity a solar panel produces is depends on three factors:
solar cell efficiency, solar panel size and the amount of sunlight directly hitting the panel.
Each solar panel should have a number listed on the back identifying how much power will be made during peak conditions, also known as a max power rating. All solar panels are rated by the DC power produced in standard test conditions. A typical solar panel produces about 200 watts of electricity based on the efficiency and size of what’s installed. For example, if you have 25 panels installed, you may have an output of about 5 kilowatts (kW).
Length and Width – The most typical size used for residential installations is 65 inches(162.5 cm) by 39 inches,(1 m) while the common size for commercial applications is 77 (192.5 cm) inches by 39 inches. it may have slight variation.
