A thermodynamic solar panel is a type of air source heat pump. Instead of a large fan to take energy from the air, it has a flat plate collector. This means the system gains energy from the sun as well as the air.

Renewable Heat Incentive
In the UK, thermodynamic solar panels cannot be used to claim the Renewable Heat Incentive. This is due to the lack of technical standards for the testing and installation. The UK Microgeneration Certification Scheme is working to develop a testing standard, either based on MIS 3001 or MIS 3005 or a brand new scheme document if appropriate.
Performance
Lab testing has been carried out by Das Wärmepumpen-Testzentrum Buchs (WPZ) in Buchs Switzerland on an Energi Eco 200esm/i thermodynamic solar panel system. This showed a Coefficient of performance of 2.8 or 2.9 (depending on tank volume).
In the UK, the first independent test is under-way at Narec Distributed Energy. So far data is available for January to April 2014.
