Solar is converted solar energy into electrical energy .The conversion of solar energy we can used the solar panel or solar cell. In old section we can use the solar cell.so we can easy can use the solar energy .Its only depend upon the sun and sun rises. Sun oriented board transformation effectiveness, commonly in the 20% territory, is diminished by clean, grime, dust, and different particulates that gather on the sun powered board. "A messy sun oriented board can lessen its energy capacities by up to 30% in high tidy/dust or abandon ranges", says Seamus Curran, relate teacher of material science at the University of Houston and executive of the Institute for Nano Energy, which spends significant time in the outline, building, and get together of nanostructures. Paying to have sun based boards cleaned is frequently not a decent venture; analysts discovered boards that had not been cleaned, or rained on, for 145 days amid a late spring dry season in California, lost just 7.4% of their effectiveness. Generally speaking, for an average private close planetary system of 5 kW, washing boards part of the way through the late spring would convert into a simple $20 pickup in power generation until the point that the mid-year dry spell closes—in around 2 ½ months. For bigger business housetop frameworks, the budgetary misfortunes are greater yet once in a while enough to warrant the cost of washing the boards. By and large, boards lost somewhat less than 0.05% of their general productivity every day
