So you’ve got solar panels on your roof—awesome! But did you know that regular solar panel service can keep your system performing at its best for 25 years or more? If your answer is “not really,” you’re not alone.
Many homeowners mistakenly believe that solar panels are maintenance-free, but similar to your car or air conditioner, they require periodic maintenance. In this guide, we’ll break down everything you need to know about maintaining your solar panels, spotting problems early, and when to call in the pros.
Let’s make solar service simple.
What’s a Solar Panel Service?
A solar panel service is a routine inspection, cleaning, and performance check of your solar power system. While panels have no moving parts and are incredibly durable, they still need care to ensure optimal energy production and long-term reliability.
Think of it like a health check for your energy system. It’s important to maintain your solar panels just as you would regularly service your car’s oil changes.
Why Solar Panel Maintenance Matters
Even a small issue—like dust buildup or a wiring fault—can cause a noticeable drop in your system’s efficiency. Over time, this can affect your electricity savings and potentially damage system components like your inverter.
Regular servicing can:
Maximize energy output
Identify faults early (before they get costly)
Extend the life of your solar equipment
Validate manufacturer warranties
Keep your air monitoring system and smart home integrations working smoothly
What’s Included in a Typical Solar Panel Service?
Most professional solar panel contractors offer a service package that includes
Visual inspection of all panels for cracks, dirt, or shading issues
Inverter check for error codes or inefficiencies
System performance testing (voltage, amperage, string current)
Wiring and connection check for loose or damaged parts
Cleaning of solar panels using safe, non-abrasive methods
Reporting with recommendations for repairs or upgrades
How Often Should You Service Solar Panels?
A sensible rule of thumb is to get your solar panels serviced once a year. However, if you live in an area with
High dust or pollution
Heavy rainfall
Bird activity or tree sap
BIPV solar panel installations, which often have more complex designs integrated into building materials, may benefit from more frequent checks and specialized maintenance.
Signs Your Solar Panels Need Servicing
Watch for these red flags:
A sudden drop in your energy output
Inverter displaying fault codes
Physical damage (cracks, discoloration, or nesting birds)
Your panels look dirty and haven’t been cleaned in 12+ months
You’re experiencing outages or system shutdowns after weather events
DIY vs Professional Solar Panel Service
You can perform a basic visual inspection and gently remove surface dust, but avoid climbing on your roof or handling wiring without proper training.
Professional service is recommended because
It includes electrical diagnostics
