You probably know by now that panels are a great source of alternative energy. Private users use this as well as big corporations in order to conserve energy and cut on costs. Because of the nature of panels that are solar that is highly dependent on solar energy that comes from sunlight, it is best to position the panels up on the roof where it can get maximum solar exposure.
Roof panel systems are two kinds. One is the off-grid solar power system and the other is the grid-tied solar power system.
The off-grid power system is a roof panel system that is independent. It only supports the area or the building of its owner. It's typically used for remote places that are not reachable by power grids. In this case, solar panels are used to generate electric power for lights and other uses.
The grid-tied solar power system is where the solar power is connected to the local electric utility's grid. In this case, excess power from the personal solar power system is directed to the local grid to be distributed to others in the area. In essence, your neighbors are also benefiting from your solar energy.
It's not that they're getting it for free. If you agree to tie your solar energy to the local power grid, the electric company will pay you for that. Is not that a great way to use roof solar panel systems? Installing roof solar panels can be quite expensive so if you share and earn, you benefit from it twice: you conserve energy and earn some cash.
