Solar is an efficient way to generate free electricity for your home without putting a strain on your wallet. Both households and businesses are opting for home solar systems in large numbers. Solar is likely to replace conventional energy sources in the near future. A 3kW solar panel system can generate enough power to meet the energy needs of a small house or business. A 3kW solar system generates 12–15 units per day. You can save between Rs. 66 and Rs. 90 per day, and between Rs. 1,650 and Rs. 2,250 per year. Within three years, the collected savings can help pay for the entire installation. You can become self-sufficient from the regional utility grid by using solar power.
