Off grid system diagram
ADVANTAGES OF OFF-GRID SOLAR SYSTEMS
1. NO ACCESS TO THE UTILITY GRID
Off-grid solar systems can be cheaper than extending power lines in certain remote areas.
Consider off-gird if you’re more than 100 yards from the grid. The costs of overhead transmission lines range from $174,000 per mile (for rural construction) to $11,000,000 per mile (for urban construction).
2. BECOME ENERGY SELF-SUFFICIENT
Living off the grid and being self-sufficient feels good. For some people, this feeling is worth more than saving money.
Energy self-sufficiency is also a form of security. Power failures on the utility grid do not affect off-grid wind systems.
On the flip side, batteries can only store a certain amount of energy, and during cloudy times, being connected to the grid is actually where the security is. You should install a backup generator to be prepared for these kinds of situations.
