Following in-depth discussions with the Distribution Network Operator (DNO), it became apparent that there would be significant extra costs involved to upgrade the connection for a large installation. We recommended a slightly smaller installation, as the upgrade would have cost several thousand pounds and required additional metering to be installed. The balance was found with a 42.12kW system and we were able to connect the system and avoid significant increased installation costs.
Panels were installed in rows, without covering any clear roof sheets. This meant that natural daylight could still enter the shed.
The inverters were wall-mounted externally within a purpose-built weather-proof structure. Each pair of panels has a power optimiser connected to ensure that the system delivers the maximum amount of electricity. From these the DC cables are connected to the inverters, and a new AC cable then runs across the other buildings back to the connection point. Merryfield Farm is now benefiting from a tailored design resulting in a good return on investment, thanks to the know-how of the experts at NWT Energy.
