Solar Panel Maintenance Services in Southern California
Serving Corona • Inland Empire • San Bernardino • Orange County • San Diego • Los Angeles
For over 33 years, Aztec Electric & Renewables has been the trusted provider of code-compliant, high-performance solar throughout Southern California. While installation is important, long-term maintenance of solar panels is the most crucial factor in ensuring that your system operates at peak efficiency for years.
Unlike national solar sales companies that subcontract or disappear after installation, we are licensed C-10 electrical contractors and renewable energy specialists. Our solar maintenance services are built on deep technical expertise in wiring, load management, troubleshooting, diagnostics, and long-term performance engineering.
Your solar panels work hard in the extreme conditions of Southern California: heat, dust, humidity, salt air, seasonal winds. They need periodic maintenance to keep output at its highest. A well-maintained system can deliver 15–25% higher production compared to a neglected one.
Aztec Electric & Renewables provides full-service professional solar panel maintenance services, including inspection, cleaning, repair, diagnostics, inverter check, monitoring, and corrective maintenance within all six major regions of SoCal.
Why Solar Panel Maintenance Matters in Southern California
While modern solar panels are very durable, Southern California does pose some unique challenges:
✔ High temperature & UV radiation (260–300 sunny days/year)
Sustained high temperatures decrease the panels’ efficiency over time.
✔ Dust, airborne debris & pollution
IE, San Bernardino, and Corona have high amounts of dust, which decreased production.
✔ Corrosion of coasts by salt
San Diego and Orange County have coastal homes that require corrosion-resistant maintenance.
✔ Frequent power surges & grid instability
Additional stress on inverters and batteries.
✔ Accumulation of ash from wildfire
Ash and soot drastically reduce the penetration of sunlight.
✔ Rooftop Pests: Birds nesting, squirrels chewing wires
One of the most common causes of panel underperformance.
Since these solar panels operate silently, most of their owners never notice a drop in production until the electric bill increases.
Routine solar maintenance ensures that:
- Maximum energy production
- Higher ROI
- Longer asset life
- Identifying problems before they become expensive
- Warranty observance
- Electrical performance safety
Solar panel systems are long-term infrastructure — they require periodic inspection much like HVAC systems, roofs, or electrical panels.
