The power developed by the solar microgrid is not constant for a particular year, it depends upon the weather conditions around the year of the specific location where the solar microgrid is operating. It is however necessary to estimate the annual average power developed by the particular microgrid before physically installing microgrid at that location. The programming based model of the photovoltaic...
