Mypower's Quercus House

Practicing what we preach...

Mypower are based in Toddington, Gloucestershire and this year sees us celebrate our 10th anniversary. 
On our own building we have a 50kW solar PV system which generates around 47,000 kWh of electricity per annum. Installed in early 2014, the projected annual electricity production figures that we produced at the time have proven to be remarkably reliable.  The actual solar electricity produced over the last 5+ years is just over 2% greater than our original projections! 

Over that time, the PV system has met over 50% of our electricity needs every year.  To achieve this high percentage, we opted to install a larger system (than we would normally recommend to clients), which meant that of the 47,000 kWh we generate per annum, approximately 54% of this is export and sold to the grid.  Whilst exporting electricity to the grid is not as commercially attractive as using the electricity onsite (we're selling at 5p/unit versus displacing grid supplied at 15p/unit), the slight increase in payback period was offset by the future potential to utilise this energy with either a battery installation or the increase in demand attributed to charging EVs.

Ready for the EV revolution

EV charging is an environmental and cost saving necessity for our business, at present we have 4 EVs and 1 Plugin Hybrid vehicle regularly charging at our offices, with more planned later this year.  We've just added a further two charging points to our parking area, and expect to see a higher percentage of our solar generation used by the business, improving the commercial returns our business has seen.

Annually we save over 15.5 tonnes of CO2 being released into the environment and with our plans for battery storage and a higher demand for EV charging we hope that within the next 3 years we will be 95% self-sufficient (as a business  you could never be completely independent from the grid!), operating completely with renewable energy.

Ben Harrison, Managing Director, Mypower...

"Solar PV continues to deliver environmental benefits and make savings for our business.  The original predictions of generation have proven to be very accurate, and the cost of the energy source (sunlight) has remained rock steady at £0! By the end of 2020 the system will have paid for itself, and will continue to produce free electricity for many years to come."
