What the client wanted

The RSPB have recently called for a ‘renewable revolution in harmony with nature’.  And they are not just talking about it.  In April 2013, Prescient Power helped them to achieve their targets with a 10kW solar panel installation on the roof of the Frampton Marsh visitor centre in the East of England.

The challenges

The site is remote and off grid.  The solar installation will help replace the demand on the diesel generator installed on site and has been configured to charge a bank of batteries during the day, to be released as demand requires.  Despite not being connected to the National Grid, the RSPB still benefits form the Feed in Tariff, inappropriately named in this instance as the tariff pays for the generation of energy, not the feed into the grid.

The end result

The installation will receive 13.50p/kWh for this tariff, which should be in the region of £1038 per year, increasing annually with inflation.  There will be the added cost saving from not having to run the diesel generator, and not to mention the reduction in noise pollution too.

This installation used a Renusol Metasole mounting system installed on a trapezoidal roof (more information on Renusol can be found on their website).  Due to the windy location quite a number of fixings were used.  The building was built to a very high specification and with solar panels in mind so no structural reinforcement was required.  The EPC rating of the building is now A+.

John Bradley, Warden of RSPB Frampton said:

“We chose Prescient Power for several reasons.  Firstly, they had an impressive pedigree, having worked on numerous successful projects for a variety of customers in the environmental sector.  Secondly, I was assured that they had the technical understanding of our complex off-grid set-up and throughly understood the many options for us regarding renewables.  And finally, I was impressed at the genuine commitment towards us as a customer.  We felt we could trust Prescient Power, they are nice people.

I was very impressed with the installation of our solar panels.  It looks in keeping with the building and, most importantly, performs as well as they said it would.  The engineers who visited were capable, personable and even collected up all the packaging and took it away for recycling.  So for someone who is used to tidying up after contractors this was quite a pleasant surprise and showed their commitment to doing a thorough job.”
