New solar and battery systems across one South West estate: a ground mount and a rooftop array at the main winery, plus off-grid systems for the back shed and Wise Winery House.

The challenge
Wise Winery isn’t one building. The estate takes in the main winery and restaurant, a new shed with workers’ accommodation behind it, and Wise Winery House. More chalets are on the way.
The winery already had about 100 kW of solar, installed bit by bit between 2012 and 2015. It was getting old, and the ground-mounted array couldn’t get any bigger because the new cabins were going in right next to it. A backup generator only covered the restaurant.
What we did
We started with a full site feasibility study. We mapped every switchboard, meter and existing system, then designed each site to suit how it actually uses power.
We managed the whole job from design through to installation, network paperwork and monitoring setup. We worked closely with our local install partners the whole way.
