Introduction

Solar hybrid systems generate power using a solar power generator likephotovoltaic (PV)modules and additional renewable energy sources (e.g. wind, biomass) and/or a supplementary generator.

In remote rural areas, that are not connected to the national electricity grid, village mini grids consisting of PV hybrid systems might be less costly than grid extension. They can replace batteries and fuel electricity generators and reach more people than single solar home systems (SHS).


Function

During the day, when the Sun is shining, the photovoltaic modules generate electricity that directly powers appliances or can be stored in a battery bank. At night or during days without sunshine the stored energy can be used. The supplementary generator makes the system reliable, offering the possibility of producing power at any time. Therefore, solar hybrid systems can offer alternating current (AC) power for 24 hours a day.

The HOMER tool, developed by the U.S. National Renewable Energy Laboratory (NREL), is useful for designing and modeling hybrid systems. The HOMER tool automatically retrieves solar insolation information from NASA.
