UK's second greenest company goes even greener and saves over £14,000 per year
Wiles Greenworld - 81kW solar PV installation
The Sunday Times described Wiles Greenworld as the second greenest company in the UK and the more we
learnt about them the more we understood why. Operating from their offices and warehouse in West London they provide supplies and services to offices in Central London, adding value to the relationship through initiatives such as the free of charge collection of recycling.
Universal values around low carbon working have been embedded in the organisation. Completely committed to reducing their own environmental impact and a transition to a zero carbon operation, Wiles Greenworld commissioned Mypower to install a 81.8kW commercial solar panels system on the roof of their warehouse.
NE facing roof, no problem
Their roof is South West and North East facing. Usually the NE facing roof is not used as the yield is less than
a SW facing roof but with a pitch of only 10% they were keen to explore the feasibility of covering both sides to maximise output and CO2 reduction. The predictions were to produce 35,300kWh from the SW facing roof and 30,900kWh from the NE roof. With scaffolding and overhead costs already covered, it was an easy decision.
Toby Robins, Sustainable Development Director at Wiles Greenworld explained: "This investment not only supports our zero carbon operation goals but also demonstrates the scale of our commitment to a move to a sustainable economy. Currently my Tesla is the only vehicle that runs on electricity but as we electrify more of our distribution fleet we are likely to be back for an extension to the installation to cover the flat roof over the offices".
Ben Harrison who heads up Mypower commented: "This project at Wiles Greenworld is proof you don't need a roof facing south to benefit immensely from solar PV. They have utilised roof space to secure their future energy and protect their business from rising energy costs. But most importantly for Wiles Greenworld this 81kw system has reduced their carbon emissions by 28 tonnes each year whilst giving an excellent ROI".
For Wiles Greenworld it is important that every customer of theirs can see that it is not 'just talk' for them, explains Toby. "Our PV array not only makes financial sense but also differentiates us in the marketplace extracting further commercial value from the initiative. Credit must go to the whole team at Mypower who calmly delivered the project against the inevitable FiT revision deadline".
Key facts and predictions - amended to March 2017 rates
• CO2 reduction of 28 tonnes per annum
• Predicted income and savings over £9,000 per annum - assuming 75% on site usage
• Pay back is 9 years
• ROI 11%
• 81.8kW half facing SW and half NE
• 20 year projected income equals £315,700
In the first 12 months the system produced 73,556kWh of electricity compared to the predicted level of 66,383kWh - over 10.8% more than projected.
All this despite half of the system facing NE.
