Think of solar greenhouse heaters as a way to supplement existing heating systems. They're out there, but some assembly may be required.

A passive solar-heated home needs no solar panels to heat or cool it. Rather, the energy used to heat and cool a house comes directly from the sun through skylights and windows. Some of that energy is ...

Solar heaters use energy from the sun to create heat. These heaters encompass a variety of products, such as solar hot water heaters, solar pool heaters and solar space heaters that can warm up small ...

Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling ...

A group of researchers in Iran has analyzed the coefficient of performance and the energy consumption of a solar-assisted heat pumps and an air-source heat pumps and has found that three factors are ...

Pairing solar with reverse-cycle heating can cut winter costs significantly, but timing matters. Daytime heating shines on ...

A new solar device generates 15 times more energy: a breakthrough in thermoelectric generators converts solar heat into ...
