Bristol’s biggest solar PV system exceeds expectations

By Katie Anderson on March 1st, 2013

Bristol’s science and technology centre is celebrating after discovering that its solar panel system is exceeding all expectations in terms of the amount of power the panels have generated over the past 12 months.¬†

In a move designed to help cut its carbon footprint, At-Bristol contracted local solar energy company Solarsense to install a 208 solar PV panel system in February 2012. Supported by a grant from EDF Energy’s Green Fund, the solar array proudly adorns the popular science centre’s rooftop, approximately the size of two tennis courts.

At the time of installation it was estimated that the solar panels would be capable of producing around 47,000 kWh of electricity annually. However the leading science centre has revealed that the 50 kWp system has in fact managed to exceeded all expectations, generating 48,637 kWh. The system had its best month last May and produced 6,791 kWh of solar electricity.

Commenting on the results, the centre’s Sustainability Manager Chris Dunford said the were delighted by the revelation that the solar system had produced more solar power than originally hoped. “The results we’ve produced over the year have been brilliant, and exceeding what we planned is fantastic.”

Perhaps most interestingly the solar panels performed best on days which were cool and bright, at opposed to really hot days which, let’s face it, are few and far between in the UK.

“It’s not actually the hottest days that produce the most amount of energy as there’s almost too much heat for the panels to cope with, instead it’s bright but cool days they work at their most efficient,” explains Chris.

Consequently, At-Bristol has also managed to reduce its carbon footprint even further. The centre had aimed to cut carbon emissions by around 25 tonnes of carbon dioxide annually, but that target has been well and truly met by almost 3,000 kg of CO2.

Earn Money via the Feed-In TarrifThe Government's Feed-In Tariff was launched on April 1st 2010 to encourage homeowners to generate their own electricity - it is split into two methods of revenue.

The Generation Tariff earns you a fixed income for every kilowatt hour of electricity you generate. And, The Export Tariff earns you income for every kilowatt hour you generate and sell back to the grid.

An average 3/4 bedroom house fitted with 2.5kw Solar PV panels and normal electricity usage would earn over £850 p/a tax free!

Add this to an approximate £145 reduction in your electricity usage and you could benefit by over £1,000 per year.
