Selected work

Less talk. More watts.

A few rooftops, a lot of teamwork, and solar that’s ready to work for your home and business

Utility scale

Rooftop generation measured in acres, with dedicated maintenance walkways — because an array nobody can safely walk is an array nobody maintains. Our largest to date is a 16.8 MWp roof, the biggest single-roof installation in Africa, where we ran the installation with over seventy installers on site as installation subcontractor.

And what scheduled cleaning looks like — the maintenance most systems in Ghana quietly need and rarely get.
