Solar Panel Maintenance & Aftercare Tips

People often wonder how much effort goes into maintaining a brand-new solar panel system, and the honest answer is: not much at all! One of the biggest perks of solar panels is their minimal upkeep, thanks to the fact that they have no moving parts. While we at Project Solar always recommend professional servicing, there are still some simple steps you can take to keep your system operating at peak efficiency.

 

Regular Inspections

It's not uncommon for critters like birds, squirrels, and other small animals to view solar panels as cozy shelters, especially since they emit warmth as part of their energy production process. To prevent these furry intruders from causing damage, consider installing solar panel mesh during installation. This creates a barrier that keeps debris and pests out. Alternatively, you can purchase and install it later on your own. Regular checks can help spot any potential issues early on, ensuring your system remains undisturbed.

 

Keep Your Panels Clean

Even without moving parts, solar panels require attention to keep their surfaces free of debris like twigs, leaves, pollen, and dust. Accumulated grime can block sunlight from reaching the cells, reducing your system's efficiency. If you're planning to clean your panels yourself, avoid using abrasive materials to prevent scratching the protective glass over the solar cells. A mixture of rubbing alcohol and water, paired with a soft cloth, works well. For safety, use a long-handled wiper while standing on the ground. If you must climb onto the roof, wear proper safety gear like a harness and non-slip shoes, as the roof can get slippery after cleaning.

Optimal cleaning times are early morning or on overcast days to avoid burns from overheated panels. Depending on your location and environmental factors, cleaning your panels once or twice a year is usually enough. However, areas prone to pollution or heavy vegetation might benefit from seasonal cleanings. Interestingly, solar panels are somewhat self-cleaning due to rainfall, so unless you notice visible buildup, they may only need occasional attention. Still, periodic inspections are crucial to catch any performance dips before they significantly impact your energy bills.

 

Monitor Sunlight Exposure

During installation, our team ensures optimal placement for maximum sunlight absorption. However, natural growth or new structures can cast shadows over time. Regularly assess whether any obstructions are blocking sunlight from reaching your panels. If you find anything hindering their performance, take prompt action to clear the obstruction.

 

Signs It’s Time to Clean Your Panels

While visual inspection is straightforward, identifying dirt from ground level can be challenging. A more reliable method is checking the accompanying solar panel app, which tracks energy output. On sunny days, if production falls below expected levels, it's likely time for a thorough cleaning.
