The problem

Solar O&M is stuck in 2014.

The inverters have telemetry. The roofs have optimisers. The data is flowing. It's just sitting in twelve different portals, in a spreadsheet nobody updates, and in the head of whichever engineer last visited the site.

01 / 04

You find out from the client

Performance drops 40%. The first email you get is from the Brewery asking why their bill went up. Inverter APIs already knew -- but nobody was watching.

02 / 04

Every inverter vendor is an island

SolarEdge in one tab. Sungrow in another. Huawei in a third. No unified view, no shared taxonomy, no way to compare a portfolio.

03 / 04

Spreadsheet-as-CMMS

Service visits live in a shared drive. Warranty claims are in someone's inbox. Historical faults vanish when the engineer who saw them leaves.

04 / 04

Client reports eat a Friday

Monthly PDFs. Copy numbers, paste numbers, export charts, fix the logo, attach, send. Forty sites times twelve months = a full-time job.

The product

Four surfaces. One workflow. Everything an O&M team does in a day.

Every site, one grid.

A portfolio that reads itself.

Twenty-eight sites, sorted by the one thing that matters right now: whose performance just dropped. Status dots. Power vs rated. Deltas. Open cases. No skim, no scroll.

Sort by performance delta, not alphabetical. Worst-performing first.

Real-time power, generation, revenue -- in the units your ops team speaks.

Our story

Built by the operators who got tired of the spreadsheet.

SolarFleet started life as an internal tool at InspireGreen -- a Welsh renewables company that installs and maintains commercial solar across the UK. After five years of juggling ten inverter portals and a shared Excel file, we built what we actually wanted to use.

In 2024 we spun it out. Today it runs on 340+ sites, from brewery roofs in Brecon to distribution centres in Dundee. Our engineers still use it every day -- which means every release gets the "is this actually better than what we had?" test.

Numbers that matter

Running live on 340+ UK sites.

These aren't projections. They're rolling 90-day averages across the portfolios currently running on SolarFleet -- same metrics the ops teams stare at every day.

“
Before SolarFleet, a string-level fault could sit for a fortnight before anyone noticed. Now I see it on my phone before I've had my second coffee. The brewery PM thinks we're wizards.
Rhys Prydderch
Head of O&M, InspireGreen
“We migrated 68 sites in a weekend.”
“I expected a two-month project. The SolarFleet team had our whole estate live by Monday morning.”
Mair T. · Ops Director, SunFirst
“Our client reports now send themselves.”
“I got a Friday afternoon back. Then I got another one. Then I stopped counting.”

Integrations

Plays nicely with every inverter you already own.

SolarFleet normalises telemetry from every major inverter vendor into one taxonomy. New brand on the roof next month? We probably already speak it.

Typical pilot: one site live in 48 hours, full portfolio in two weeks. We handle the inverter API credentials, taxonomy normalisation, and historical backfill. You keep drinking coffee.
