Solar Panel Maintenance & Cleaning in Franklin
Protect your solar investment with Lehmann Electrical’s maintenance programs. Franklin’s mature tree canopy and seasonal pollen make regular professional cleaning essential for peak performance.
Panel Cleaning & Soiling Recovery
Pollen, dust, bird droppings, and leaf debris reduce output by 5% to 25%. Professional cleaning with deionized water restores production. Recommended once or twice per year for West Allis homes.
Annual System Inspection
Verify wiring connections, inverter performance, and overall system health. Catch micro-cracks, hot spots, and degradation before they reduce output or void warranty coverage.
Critter Guards & Pest Prevention
Birds, squirrels, and other wildlife nest under panels, damaging wiring and reducing airflow. Critter guard mesh prevents nesting without affecting performance.
Inverter Maintenance
Inverters last 12 to 25 years. Monitoring catches error codes, communication failures, and production drops. Connection tightening prevents arc faults.
Degradation Monitoring
Panels degrade at approximately 0.5% per year. Production monitoring through Enphase or SolarEdge tracks actual vs. expected output for early issue detection.
Seasonal Franklin Maintenance
Spring: clean pollen and winter debris, inspect for storm damage. Fall: clear leaves from the mature canopy along the the Root River Parkway and the Root River, check connections before winter.
