Stand-alone Solar Power Systems, Stand-alone PV Systems and Off-grid Power Systemsoperate independently of the electric utility grid (off-grid) and are most often used in remote rural areas where the electric grid does not reach or where the connection fees for access to the grid are higher than the cost of an alternative energy system. The DC power generated by these systems is stored in batteries and converted to AC power for household or commercial use. Stand-alone Solar Power System are best suited for remote village and rural electrification projects, and provide a more affordable and reliable source of electricity, particularly in more remote rural areas utilizing only diesel generators.
Advantages of Off-Grid Solar Systems
1. No access to the utility grid
Off-grid solar systems can be cheaper than extending power lines or power diesel generator in certain remote areas.
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 solar systems.
