Proper Repairs Protect Your Roof

Expert Care for Your Solar Investment

Is your solar energy system underperforming, showing an app alert, or inverter error code? At Marcor Solar, we specialize in bringing residential and commercial solar arrays back to peak performance. Solar panels are a long-term investment, but environmental wear, technical glitches, or workmanship mistakes can affect your return on investment. Our team of certified technicians provides comprehensive diagnostic analysis and troubleshooting to pinpoint exactly where your system is losing energy, ensuring you aren't left in the dark—or stuck with a high utility bill.

Comprehensive Repair Solutions

From the roof to the electrical panel, we handle repairs on every component of your solar infrastructure. Our services include inverter repair and replacement, fixing faulty wiring, replacing cracked panels, and resolving complex electrical issues that stop your system from communicating with the grid. Beyond the tech failures, we are also prepared to also address external threats to your system. We recommend installing high-quality critter guards to prevent nesting pests from damaging your wiring. No matter the scale—whether it’s a backyard residential setup or a sprawling commercial rooftop—we have the tools and expertise to get the job done right.
