The house solar battery provides many benefits. First of all, it reduces or even completely eliminates electricity bills by taking in free energy from the sun. Second, it offers a reliable power supply during power disruptions from the grid bringing greater safety and comfort to homes. Third, reducing reliance on fossil fuels and emitting far less carbon than can a conventional power plant, it contributes even more to our living environment. In addition, these batteries are quiet in operation since there are no moving parts and they require only minimal maintenance. Furthermore, government incentives and the falling cost of solar technology make investing in a solar battery economically viable. Finally, the opportunity to store surplus electricity meant homeowners could even sell power back to the grid -- yet another source of income.
