Solar Panel Case Study - Solar and air source heat pump


These Velux flat plate collectors (lower centre) are integrated into the zinc roof of this eco-build property. The solar heat is delivered to a 185 litre pressurised hot water cylinder with a 120 litre pre-feed cylinder which is also connected to a Genvex air source heat pump and MHVR system.

The solar PV installation above helps to off-set the electricity required by the ASHP and MHVR system. 



Feed in Tariff scheme

The FIT is a scheme in which owners of PV systems are rewarded for every unit of electricity they generate, irrespective of whether they are used on site or not.

This is known as the Generation Tariff and is currently under review. Payments are also made for 50% of every unit generated by the PV system. This is known as the Export Tariff and is currently under review. These payment rates are fixed for 20 years, linked to the Retail Price Index (RPI) and are tax-free. PV systems installed from 1 August 2012 will be subject to an approximate 7% decrease in the FIT rates.
