Why maintenance matters
Find out why your solar output has changed.
A higher bill can come from lower generation, higher consumption or a metering issue. Dust is one possible cause, alongside shade, inverter downtime, electrical faults and seasonal weather. A useful inspection separates these before recommending cleaning or repair.
Bring recent inverter generation records and electricity bills where available. We compare the same periods, note changes in weather or consumption, and record the condition of panels, wiring, structure and inverter. Before-and-after output is useful only when the measurement conditions are comparable.
