Rooftop thermal collector
A solar water heater is a system that uses sunlight to heat water for domestic or commercial use.
Rooftop panels absorb solar energy and transfer it to water stored in an insulated tank: We installed a solar water heater to cut our energy bills.
The technology ranges from simple passive systems to more complex active ones with pumps and controllers.
