Hybrid PV systems are designed to increase the reliability of solar. In hybrid PV systems, the most used conventional source is a diesel generator. The benefit of integration of photovoltaic energy with conventional fossil fuel based generator is that the weakness of solar are complemented by the strength of the generator and conversely. Solar resource, as all other renewable source of energy, is variable in nature; it’s can’t all the time and everywhere be reliable. A generator which can locally produce enough power to supply the load makes hybrid systems more reliable.

Hybrid PV systems are suitable for off grid or unreliable grid areas, they are the best solution:

*Where a generator could be used 24h/7;
*When the effective cost of fuel at the point of consumption, including transportation and storage, exceed one dollar per liter;
*Where there is willingness to save operational expenditure or to reduce on CO2 emissions and going green.

This short course provides a quick recap of Solar PV basics and then walk you through the main planning steps of a Diesel - PV hybrid system.
