One hundred and twenty panels across a cattle shed, sized for daytime cooling loads.
The brief
Milk cooling and water heating run through the day, so Gerry needed generation, not storage.
What we fitted
One hundred and twenty panels on two shed roofs feeding a 50 kW inverter, with export limited to the farm’s grid connection.
Twelve months on
The system beat its yield estimate by 6%. Grid paperwork added a week to the job, and we handled it with the network operator.

In their words
It took a week longer than planned because of grid paperwork, but they chased it, not me. Yield is 6% over the estimate.
