Can photovoltaic and air source heat pump be combined?

Combining photovoltaic (PV) with air source heat pump (ASHP) yields a great potential in providing heating and domestic hot water (DHW) supply in non-central heating areas. However, the diurnal and seasonal inconsistencies between solar availability and building heat load can severely affect the efficacy of solar energy systems.

What is solar assisted air source heat pump?

Evolutions require new-generation energy efficiency and green refrigerants. Solar assisted air source heat pump shows great potential as a promising energy-saving heating technology, which integrates solar collector and air source heat pump.
