By its very name, a hybrid solar hot water system relies on a combination of systems or technologies as means to boost or ensure optimal heat-sustaining efficiency. The solar water heater may source its power from solar panels, a natural gas back up, or through micro-grid inverters. An electric water heater may also derive power from solar wave sources, making it a hybrid system.
An example of a hybrid solar hot water system is a technology that combines the installation of solar PV panels on the roof of a home or building and the setting up of a solar hot water heater directly underneath it.
Oftentimes, this hybrid technology is put up as a way to address the excessive heat being absorbed by the panels. Too much heat absorption can potentially damage the panels over a period of time. Diverting heat into the water system can effectively manage excessive heat absorption and prevent solar panel failures.
