Collective Self-Consumption

The future of solar power: sharing energy locally.

Subsidies are gradually decreasing. Project profitability now relies on self-consumption, storage and local energy sharing. A single plant can supply several nearby consumers: businesses, public buildings, housing, shops or EV charging stations.

Why STEIM?

Because a photovoltaic project isn't just about mounting panels. You need to know how to connect, protect, supervise, operate and evolve the installation over time.

An integrator's approach

Our industrial DNA allows us to treat projects as complete energy installations: production, usage, safety, maintenance and control.

Your solar project deserves a complete technical approach.

STEIM designs, integrates and supervises sustainable energy solutions: photovoltaic production, self-consumption, storage, local energy sharing and usage management.
