Challenge
Consumption was concentrated in the summer months — exactly when the energy bill was putting pressure on the winery's margin.
Solution
81 bifacial panels on a flat-roof mounting structure, two three-phase inverters and monitoring for each production circuit.
Result
A 68% reduction in the annual bill and a projected payback of just over three years, with the investment depreciated for tax purposes.
“It was the investment with the best return we've made at the winery in the last ten years.”
