Description:
Yes! Solar energy is the most abundant and clean energy source out there. There is no energy shortage and there need not be. We just have to learn to capture the sun's energy more effectively. Necessity is the mother in invention. We would do it if we felt that we had to. Wind resources and solar resources could easily replace all our power plants if we put a little effort into it.
Grid-tie solar power system
Most modern PV systems are grid-connected, meaning electrical energy is directed into the existing municipal power grid.
Energy is effectively stored in the grid. When a grid-tie system is generating more energy than you need: your electrical meter turns backwards. Many large arrays are intended solely for use as power plants, enhancing or supplanting the need for conventional power plants. Grid application systems do not need large batteries.
Off-Grid solar power system
Many PV systems are used to energize remote homes, facilities, and devices.
Energy is gathered from solar modules and is directed into energy storage devices for use when needed. These systems often supply the entire amount of energy required.
