Solar hybrid systems generate power using a solar power generator like photovoltaic (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.
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.
PV-Diesel Hybrid Mini-Grid
A first evaluation of one of the possible appliances of Solar Hybrid Systems is given regarding GIZ experiences in Senegal: PV-Diesel Hybrid Mini-Grid.
