01
The problem
Grid interruptions during the plucking season were stalling withering lofts mid-cycle, and a stalled loft costs a whole day's leaf.
02
What we built
A 22 kW roof and terrace array across two factory blocks, a 60 kWh bank in a purpose-built ventilated room, and 20 kW of hybrid inversion split across critical and non-critical boards.
03
The result
Withering and rolling now ride through every dropout. The estate reports no leaf loss to power failure across two full seasons.
