Solar assisted heat pumps (SAHP) combine an air-to-water heat pump with a Thermodynamic panel and heat pump are usually linked directly, sharing the same refrigeration circuit. Heat from the outdoor air is absorbed by the solar collector into a refrigerant gas.

Solar assisted heat pumps are becoming more common in households because they have many advantages over traditional mechanical systems. Solar assisted heat pumps have the ability to operate in climates that are unsuitable for traditional mechanical systems, such as cold weather and high altitude. They also have low operating costs, because they use solar energy to convert thermal energy into mechanical energy.
