The good news: a solar array has no engine, no oil, nothing to wear out monthly. The honest news: neglect still costs you 5–15% of production. Here is the routine we teach every customer.
Monthly (30 minutes)
- Rinse the panels early morning or evening — never spray cold water on hot glass. Soft brush for bird droppings; they cause hot-spots.
- Check the app. Compare this month's generation to the same month last year. A sudden drop means shade, soiling, or a fault.
- Look and listen at the inverter: green light, no error codes, vents free of dust and wasp nests.
Yearly (professional visit)
- Torque-check DC and AC terminations (loose lugs are the #1 fire cause).
- Thermal-scan the array for hot cells.
- Test earthing and surge protection.
- Inspect structure bolts and roof penetrations for corrosion.
Every Sun Power Solution installation includes first-year service free, and our O&M plans keep institutional plants at contract-guaranteed performance ratios.
