Solarsense Install UKs Largest Local Authority Rooftop PV System

Solarsense has completed the largest Local Authority owned PV system in the UK on the roof of the Northacre Resource Recovery Centre (RRC).

The 1,248 Vikram Eldora solar panels (318.24 kWp) – covering an area equivalent to more than seven tennis courts – will generate over 280,500 units (kWh) of electricity each year. The electricity, all of which will be consumed on site, will help to power the mechanical biological treatment process used to turn household waste into solid recovered fuel (SRF) in place of it being sent to landfill.

The benefits of the solar panel system to Wiltshire Council are significant, with annual bill savings and income from the Feed-in Tariff of over £55,000, as well as annual CO2 emission reductions of 148 tonnes. Over 20 years the benefits are expected to exceed £1.5 million, and avoid CO2 emissions of over 2,720 tonnes.

Crucially for a plant such as Northacre RRC with a high energy requirement, the unit price of electricity produced by the panels over the system’s 25 year life is significantly less than the current rate for grid supplied electricity.

Toby Sturgis, cabinet member for waste said: “As a council we are committed to finding sustainable solutions to our energy requirements as well as cutting costs where possible so more can be spent on frontline services. This is an ideal oppor tunity to use renewable energy to power a site which uses innovative technology and I’m delighted that we are
leading the way in doing this.”

David Snape, Commercial Manager at Solarsense, the company responsible for the design and installation of the syst
em said: “The Northacre RRC project is a great example of how solar PV can significantly reduce consumption and deliver long-term cost savings for industrial processes. As the developer of the largest Local Authority rooftop PV installation in the UK, Wiltshire Council is making a very clear long-term commitment to carbon reduction
and sustainability, as well as a very sound investment which will benefit the county.”
