Project Overview
Thompsons was approached by the building landlord to provide an investment model which would benefit both owner and tenant. A solar scheme was proposed that would enable the landlord to receive an income from the generated power used on site thus providing them with a return on investment.
In turn, the tenant would benefit from lower carbon technology without an initial outlay for installation. The installation will enhance their environmental credentials and provide them with greener power at an agreed, fixed rate.

Installation
The building has a flat roof with several vents and obstructions. A system was designed that would work around these elements whilst making best use of the space available. As there is some overshading on the roof, solar optimisers have been included to ensure optimal yield from the installation.
The Esdec wave mounting system was used to provide the required pitch of the panels. Prior to installation, a structural assessment was carried out to ensure the roofs stability following installation of the generational equipment along with ballast required.
Technical Information
Electrical consumption prior to solar installation: 208550kW hrs PA
Installed Solar Capacity: 127.02kW
Projected yield from installed solar: 108,002W hr PA
Net Rate of return on investment: 33%
System Performance warranties (manufacturer) 25yr – 80% original performance
Environmental Benefits
Annual CO2 saving: 27tons
Equivalent trees planted: 263
Completion Commissioning, Performance
The system was commissioned in December before the holiday shutdown and so savings won’t be known until the new year. Once the factory is back operational, the installation is expected to generate the equivalent of over 50% of current on-site usage.
