Common Questions About Solar Maintenance
For most residential and commercial solar installations, we recommend a comprehensive professional maintenance check at least once per year. However, systems in areas with heavy pollution, dust, pollen, or bird activity may benefit from bi-annual servicing. Our monitoring systems can also alert you to performance drops that might indicate a need for maintenance outside of regular schedules.
While basic visual inspections can be performed by homeowners, professional maintenance is strongly recommended for safety reasons and to protect your warranty. Solar systems involve high voltage electricity and are typically installed in hard-to-access locations. Our technicians have the proper safety equipment, specialized tools, and expertise to safely maintain your system without risking injury or damage to the components.
For clients on our maintenance plans, we offer priority service with response times typically within 24-48 hours for most issues. Critical system failures receive even faster attention. For non-plan customers, our response time is generally 3-5 business days depending on current service volume and the nature of the problem. Emergency service options are available at additional cost for situations requiring immediate attention.
Importance of Solar Maintenance & Repair
- Maximizes Efficiency
- Dust, dirt, bird droppings, or shading can reduce energy output by 10 – 30%. Regular cleaning restores peak efficiency.
- Extends Lifespan
- Well-maintained systems last longer, protecting your investment.
- Prevents Failures
- Early detection of loose wiring, inverter issues, or panel degradation avoids costly breakdowns.
- Ensures Safety
- Prevents overheating, electrical hazards, or fire risks.
- Maintains Warranty
- Many manufacturer warranties require documented professional servicing.
- Improves ROI
- Keeps generation consistent, ensuring expected financial returns.
Key Maintenance Services
- Solar Panel Cleaning
- Removal of dust, leaves, bird droppings, and pollution build-up.
- Can boost generation by 10–15%.
- Methods: manual cleaning with water/soft brushes, robotic cleaning, or waterless nano-coating.
- System Inspection
- Visual check of panels, frames, junction boxes, wiring, and mounting structures.
- Identifies cracks, corrosion, or loose parts.
- Electrical Checks
- Inspection of wiring, connections, isolators, and circuit breakers.
- Thermal imaging to detect hotspots.
- Grounding and earthing checks.
- Inverter Servicing
- Inverters are the heart of a solar system and often fail before panels.
