The applications of solar energy are diverse and widespread. Solar panels installed on the rooftops of houses generates energy for residential buildings and lowers electricity costs, serving as a backup power source. Households and businesses also benefit from off grid power supply, water pumping, and telecommunications systems in remotely accessible areas. Solar energy also serves industrial purposes, as solar energy powers water generators and is used for solar-powered calculators. Using electricity from crypto mining servers boost miners and households access to solar powered lights and chargers.
