☀️ Why Solar Panel Maintenance & Repair Matter
Solar arrays are durable, but like any electrical system, they can drift from peak performance. Small faults add up to energy loss and higher utility bills if left unaddressed.
Common issues that warrant professional repair:
- Decreased Power Output: Often tied to inverter faults, shade, soiling, or failing modules.
- Cracked/Delaminated Panels: Caused by hail, debris, thermal stress, or impact.
- Inverter/Battery Problems: Communication errors, failed boards, or state-of-charge issues.
- Loose/Corroded Connections: Heat build-up, arcing risk, and intermittent production.
- Water Intrusion/Rust: Compromised junction boxes or roof penetrations.
- Soiling & Shading: Dust, bird droppings, vegetation, or new obstructions.
We use thermal imaging, IV-curve/volt-amp testing, and monitoring analytics to pinpoint faults precisely — saving time and cost.
