Pioneering renewable energy for business and communities & more

Walking the walk

WolfeWare operates from premises with no gas supply, heated and partly powered by renewable energy

Solar panels in front of our premises

Ground source heat pump

Renewable heat

Heat store cylinders

All the heating and hot water for Rose Cottage comes from solar thermal panels and a ground source heat pump. The heat pump extracts heat from fluid pumped through four 30m boreholes in the front driveway. The heat pump itself (left) is the size of a large boiler.

This heat store (right) with two large cylinders and various expansion vessels makes sure we have plenty of hot water and the heat is used as efficiently as possible.

Solar thermal system controls

The solar panels are mounted on a frame in the garden (see picture below), with the controls shown on the right in the garage.

Air source heat pump

The heating circuit for the house is partly underfloor heating, and partly standard hot water radiators.

We disconnected the gas when the ground source heat pump and solar thermal systems were installed. Through a minor oversight, that left the swimming pool unheated, so an air source heat pump has now been fitted.

 

Photovoltaic and solar thermal panels

Solar panels

 

These solar panels mounted in the garden face almost exactly due South and provide both heat and electricity.

 

We found solar panels with sizes and frames that matched so you can hardly tell the electric panels (on the left) from the heating panels (the three on the right) ... and yes, we did cut back the hedge to avoid shading!

 

Renewable power

Part of the electricity is produced by the photovoltaic panels alongside the solar thermal panels. We would have liked to install a wind turbine, but wind-speed monitoring show that our site is not windy enough.

PV system inverter
Repeater unit for PV system inverter

Because the inverter (left) for the PV panels is in the shed under the array, we hardly ever see it, so we have a wireless repeater in the house (right) to see how the system is performing.

It shows a maximum output of 1,463 watts (so far) - not bad for an array rated at 1,280W.
