Yet, many homeowners unknowingly make mistakes that reduce solar performance—or worse, put their investment at risk.

 

If you already have a solar energy system—or are considering installing one—watch out for these common solar panel maintenance mistakes and follow our expert tips to keep your system running at full capacity.

1. Skipping regular solar panel maintenance

 

One of the biggest misconceptions is that solar panels are “maintenance-free.” While they’re built to resist weather, dirt, dust, bird droppings, and leaves can block sunlight and lower efficiency by up to 25%.

 

✅ How to avoid it:

Set up a maintenance schedule based on your region:

  • 🌦️ Rainy climates: once a year

  • 🏙️ Urban areas with pollution: every 6 months

  • 🌵 Dry or bird-heavy zones: every 3–4 months

If you notice a drop in energy production, your panels might need cleaning sooner than expected.

 

 

2.  Using the wrong productos for cleaning solar panels

 

Cleaning panels with abrasive products or rough tools can scratch the glass surface and reduce light absorption. Harsh detergents can damage the protective coating, shortening your system’s lifespan.

 

✅ How to avoid it: 

A soft rinse with water and a microfiber cloth is fine for basic cleaning. But for best results, professional maintenance is highly recommended.

3. Ignoring your solar energy system’s electrical connections

 

Maintenance isn’t just about clean panels—it’s also about system health. Loose or damaged wiring can lead to energy loss or pose a fire risk.

✅ How to avoid it:

Do visual checks, and at least once a year, have a certified technician inspect connections, inverters, and battery health.


👉Zolarzo’s inspections include a full diagnostic of your system to catch problems early.

 

 

4.Doing all your solar panel maintenance yourself

 

It’s tempting to handle everything on your own—but DIY maintenance can lead to accidental damage or voided warranties.

Cleaning is one thing. Diagnosing inverter errors or checking voltage is another.
