The sun is the primary source of energy. The solar panel is made from silicon and a large amount of crystal. Solar panel are absorb the sun rays and generate the electricity. Solar cells have many applications but solar water heating system is the common application of solar panel. Solar panel can be calculated by MPP. The solar cells convert the sun’s energy into electricity. The solar energy is a renewable energy. The renewable energy is clean, affordable and domestic. The solar power is cheaper than ever. The solar panel is also called modules. A single solar component can manufacture only a restricted amount of supremacy; most installations contain numerous modules. Several companies contain begun embedding electronics into PV modules.
