What We Offer
Solar Maintenance Services
Solar Panel Cleaning
Dust, pollen, bird droppings, and grime can reduce solar output by 15–25%. Our professional cleaning service restores peak performance using deionized water and soft-bristle tools that won't scratch panels.
Annual System Inspection
Comprehensive inspection of panels, racking, wiring, inverters, and monitoring systems. We identify degraded components, loose connections, and potential safety issues before they become costly failures.
Inverter Diagnostics & Repair
Inverter faults are the #1 cause of solar system downtime. We diagnose string inverters, microinverters, and power optimizers — and repair or replace failed units to restore full output.
Performance Monitoring Review
We analyze your system's production data to identify underperforming strings, shading issues, or degraded panels — and provide a clear action plan to maximize your energy yield.
Wiring & Connection Inspection
UV-degraded wiring, loose MC4 connectors, and corroded junction boxes are common in older systems. We inspect and remediate wiring issues to prevent arc faults and production losses.
Panel Replacement & Upgrades
Damaged or degraded panels replaced with current-generation modules. We handle the electrical work, permitting, and utility notification so your system stays compliant.
