GREYFUSION
Vast photovoltaic solar array at golden hour
Renewable Energy

Power that answers to engineering.

48MW deployed. 99.2% fleet uptime. Every system we ship is sized from measured load data and real irradiance — then guaranteed in the contract, not the brochure.

⚡ Engineering-grade sizing

Pro ESS — solar & storage sizing engine

Build your load profile and get a first-pass battery bank, PV array and hybrid inverter specification — sized with LiFePO₄ depth-of-discharge, West African peak-sun-hours and real system-loss factors, not thumb rules.
