Garsdale Head Depot
Thirty-five panels over a workshop and vehicle bay that draws hardest between nine and four, which is the shape of load solar is actually good at.
A workshop, a vehicle bay and a compressor that cycles all day. Seventy-four percent of what this array makes is consumed on site before it reaches the meter.
Commercial load, domestic array size
Fifteen point four kilowatts is a small commercial system. It is sized to the base load, not to the roof, so that almost nothing is exported at five pence.
Payback
Under eight years on the figures at the time of install, against the twenty-plus you would see on a domestic roof with the same array and a third of the daytime load.
The system
GBP 18,200
GBP 6,480
GBP 1,930
Seventy-four percent of it never leaves the site. That number is why the payback here is under eight years and not over twenty.
