Frequently Asked Questions
How were these numbers calculated?
All numbers in this case study are taken from real installed-fleet performance — not modelled forecasts. Generation data is from the inverter monitoring system; savings are calculated against the customer's actual electricity tariff at the time of install.
Can you build a similar system for my business?
Yes — every case study profile is replicable on similarly-sized properties. Send us your half-hourly meter data and a roof sketch; we'll return a free desk feasibility within 5 working days.
Why use representative case studies?
Some customers prefer not to be named publicly for commercial reasons. Where the customer wishes to be named, we publish full attribution. Where confidentiality is preferred, we publish the project at the same scale and with the same financial structure as the original.
How does payback compare across our other installs?
Across our installed fleet of 350+ commercial systems, payback typically falls in the 3.5–5.5 year range. The 25-year cumulative saving runs 6–10× the original capital outlay.
Can I visit a similar live installation?
In many cases, yes — subject to host customer agreement. Reference visits are arranged where the host customer is willing and where commercial sensitivities don't prevent it.
