Villages can now have access to electricity by investing in their own micro-grid power plant. The size of a solar microgrid depends upon the number of solar panels and wattage comprising the solar array. The requirement and size of a micro-grid is calculated by adding the power needs of individual homes in the village that will be connected together.
A typical solar micro-grid can range from 1 KW to several megawatts. A typical rural house requires approximately 2 units of electricity and so, for a village of 100 homes, a 4 KW micro-grid is sufficient. A 4 KW plant helps generate electricity worth Rs 33,000 per year.
