Drivers for the project

To reduce Carbon Emissions and help save on energy costs.


As part of the initial design phase our design engineering team reviewed the clients half hourly electrical data in order to size the solar system appropriately. A number of options were presented to the client based on current and future electrical consumption usage on site.

A 29.945 kWp system was chosen comprising of 113 No. 265Wp panels and 2 No. 12.5kW Fronius inverters. Suitable isolators, a new dedicated PV distribution board and generation meter were installed and fitted seamlessly into the sites existing electrical network.

The system will produce enough electricity (26,419 kWh per annum) to power around 7 residential houses per year and 12 electric cars. After 25 years in operation the project is predicted to have saved 52.6 tonnes of CO2e, an equivalent of 272,223 fossil fuelled car miles, 35 fossil fuelled cars off the road and 210 pine trees planted.


A large amount of scaffold was required at the site, AC cable run’s through the building was complicated but overcome. Extensive analysis was required to correctly match array sizes to inverters for optimum efficiency.


The initial programme was to complete the installation within three days and we successfully delivered a fully commissioned system following a client handover within this period.
