Several hybrid RE technologies have been also studied and compared, to improve the overall performance of RE in generating electricity.

Hybrid power

Another example of a hybrid energy system is a photovoltaic array coupled with a wind turbine. [7] This would create more output from the wind turbine during the winter, whereas during the summer, the solar panels would produce their peak output. Hybrid energy systems often yield greater economic and environmental returns than wind, solar, geothermal or trigeneration
