Maintenance Myths - Solar Connection Solar Connection

Many solar owners believe once panels are installed, they can just “set it and forget it.” While solar systems are low maintenance, they are not maintenance-free.

If you want your system to produce at peak performance for 25+ years, proper care matters.

Let’s clear up the 5 biggest myths about solar maintenance:

Truth: Solar is low maintenance—but not no maintenance. Dirt, debris, wiring issues, or worn components silently reduce efficiency by 10–25%.

Small problems left unchecked could escalate into costly repairs, void warranties, and create safety hazards. Maintenance is essential to protect performance and ROI.

Truth: Small performance drops often go unnoticed without proper monitoring of each electricity bill – and comparing it month after month, which is very time consuming and hard to spot if you don’t know what to look for.

Truth: Solar systems can underperform for years without ever fully “stopping.” Unlike a car that won’t start when something’s wrong, solar systems often fail gradually and silently. As long as the inverter is on and numbers are showing in the app, most homeowners assume everything is working perfectly.

But “producing power” does not mean “producing optimal power,” and underperformance means less savings.

Truth: Preventive maintenance prevents small issues from turning into expensive repairs. The cost of a maintenance program is typically far less than the cost of replacing parts or lost energy production over time.

Truth: Many panel warranties require documented maintenance. Skipping it can void coverage, leaving you responsible for expensive repairs.

Even if a system appears to work, small problems like corrosion or minor electrical faults can escalate into major failures. Without documented maintenance, you may end up paying for repairs that the warranty would have covered.
