Hybrid systems come in many sizes to fit the need for energy and the resources available to
the end users. Solar PV panels and gas/diesel gensets generally give good performance
where fuel is readily available but utility power is not. Sizes of systems range from home
sized (1 kW) up to village systems of megawatts with 500 kilowatts of renewables added to
the generation mix. The expected contribution of the renewable energy was to reduce the
dependence on the conventional fuel source and to stabilize the performance of the grid by
making it less “one-dimensional” in its dependence on single sources of energy or to
provide electrical power where none was available before. Small, single source, electrical
power is generally PV (50 to 100 W) or, in some cases, a small wind turbine (100 to 300 W)
and are not hybrid systems.
