Clear answer, explained.

Yes — we provide operations and maintenance services for commercial solar systems installed by other contractors. The starting point is a full system inspection to establish the current operating condition, production baseline, and any immediate maintenance or performance concerns.

We work with all major commercial inverter platforms commonly used across Canadian C&I solar installations, including Fronius, SolarEdge, Solis, SMA, and others. Following the assessment, we provide a documented inspection report, identified corrective actions if required, and a forward maintenance plan structured around the long-term operation of the system.
