Solar Minigrid Topology

Cluster micro hydro power plants has been a success story in Nepal, and various researches for stable and reliable mini grid for micro hydro is going on. But not all places of Nepal has favorable environments for micro hydro and are too far from national grid. In that case, solar mini grid can be economical and viable option in rural village far from national grid and where other alternatives like micro hydro, diesel generator are not possible or economical. Community based solar mini grid can be a a good idea to power household loads and few micro small mini enterprises. In today's society where communication devices like mobile phones has been inseparable part , rural telecommunication towers can also be benefited by such mini grids.

A simple topology for such system is presented here.
