Photovoltaic-Thermal (PVT) Installation

In the heart of Gloucestershire Encraft was recently set a new challenge in the domestic photovoltaic market. An alternative energy source was sought not solely to provide electricity to the house, but also to provide heat for domestic hot water and a swimming pool.

With a South facing rear roof Encraft engineer Andrew Hanson began designing the project based around a series of AnafSolar H-NRG Photovoltaic-Thermal (PVT) panels. With a peak electrical output of 3.22kWp, and an average annual thermal output of around 8,917kWh, the system was designed to contribute towards both the domestic hot water load and the swimming pool itself.

The PVT panels not only provide the house and pool with electricity and hot water, but with the addition of an aluminium heat exchanger, which is applied on the back face of the collector, the solar thermal works as a cooling system for the photovoltaic collectors. This, in turn, improves the efficiency of the panels and thus increases the yearly kWh production.

With a nominal average electrical output of 2,122 kWh per year, along with gas and electric savings in the region of £650, and a Feed-in Tariff income of £918, the design, implementation and delivery was a great success.
