Maintenance:
What to Know

Many people are turning to solar panels because of their cost-saving benefits. However, solar maintenance is something many homeowners overlook. If you invest in solar, your system will need regular maintenance to ensure optimal performance. In this guide, we’ll discuss everything you need to know about solar panel maintenance, from how to monitor your system and perform inspections to costs associated with solar panel services. Let’s get started!

Do Solar Panels Require Maintenance?

Yes, solar panels need regular maintenance. While panels are designed to be durable and require minimal upkeep, regular solar maintenance is essential to maximize their efficiency

How to Monitor Your
Panels’ Health

It’s important to regularly monitor your system’s health to quickly address potential issues before they become significant problems. You can use monitoring software, inverter monitoring, remote monitoring systems, and energy consumption tracking to gather data and assess your system’s overall health. By monitoring your panels, you can detect problems early on, ensure efficient energy production, and take necessary actions to extend their lifespan.

How to Maintain Solar Panels

Proper solar maintenance requires regular cleaning, inspections, and addressing repairs. Periodically cleaning your panels to remove dirt and debris helps them operate efficiently. Conducting inspections helps identify signs of damage or issues that need repairs. Quickly addressing repairs, such as fixing loose wires or replacing faulty components, ensures your panels have optimal performance. Regular maintenance helps extend the system’s lifespan and maximize the energy output of your panels.

Ground-Mounted Panel vs. Rooftop Panel Maintenance

Though they are very similar, maintaining ground-mounted solar panels and rooftop ones requires slightly different approaches. For ground-mounted panels, it’s essential to regularly inspect the mounting structure, such as checking for stability and ensuring proper alignment. It’s also important to trim trees or plants that could cast shadows or damage the panels.

Rooftop panels require regular inspections to ensure they’re free from debris like leaves or dirt. It can be challenging to access rooftop panels, so hiring a professional for cleaning and maintenance may be best.

How Often is Solar Maintenance Necessary?

How often you need to maintain your system depends on several factors, such as the specific system, weather conditions, and manufacturer recommendations. As a general rule, scheduling routine maintenance visits at least once a year is recommended. However, certain factors may require more frequent maintenance. For example, more frequent cleaning may be necessary if your panels are exposed to heavy dirt or dust. Also, if you live in an area where extreme weather conditions are common, additional inspections and maintenance may be needed.

Cleaning Your
Solar Panels

Cleaning is an important part of solar panel maintenance. To clean your solar panels, turn off the solar system and disconnect it from the power source for your safety. Use a soft brush or sponge and mild detergent to gently scrub the panels, avoiding excessive pressure. Rinse off the soap with clean water and let the panels air dry, or use a soft cloth to pat them dry. If you want to avoid rapid drying and streaking, try cleaning your panels during cooler parts of the day.

Cleaning in the Winter

Cleaning solar panels in the winter requires a few more precautions and steps because of the snow and cold temperatures. First, prioritize safety and avoid climbing on the roof or attempting to remove snow directly from the panels. Instead, focus on clearing any obstructions around the panels, like branches or icicles, that may cause shading.

If heavy snow accumulates on the panels, use a long-handled soft-bristle brush or a non-abrasive snow removal tool to gently sweep off the snow. Avoid using sharp objects or excessive force that could scratch or damage the panels.

How to Know When Solar Panel Maintenance Is Needed

Monitoring your system, inspecting it for damage or shading, and paying attention to system alerts will all help you determine when solar maintenance is needed. Monitoring energy production and comparing it to expected output can show significant drops, indicating a potential problem with the system. Inspecting your system can help detect cracks, loose wiring, or shading caused by nearby objects. System alerts also provide valuable information about any system errors.

By regularly monitoring and inspecting your system and paying attention to system alerts, you can determine when solar panel maintenance is needed. Being vigilant and responsive to maintenance indicators helps prolong your system’s lifespan.

Cost of Solar Panel Maintenance

The cost of solar maintenance can vary depending on factors such as the type of maintenance needed and the size of the system. Generally speaking, most homeowners can perform routine maintenance like cleaning and visual inspections at no additional cost. However, if more specialized maintenance or repairs are needed, it may be best to contact a professional. The cost of professional solar panel services will vary depending on the provider.

What is the Typical Warranty for Solar Panels?

Most solar panel manufacturers offer warranties that range from 20 to 25 years. These warranties typically cover the costs of defects or performance issues during that period. However, it’s important to review your warranty's specific terms and conditions to understand what’s covered and what isn’t.

Factors Affecting Solar Panel Maintenance CostSevere weather conditions are one of the biggest factors that affect the cost of solar maintenance. Extreme weather events like storms or heavy snow can damage panels, requiring additional maintenance and repairs. Environmental factors like high dust or pollution can increase cleaning frequency, while snowy regions may need extra measures to clean panels. Older systems and larger installations may also lead to higher maintenance costs.

How to Repair or Replace Solar PanelsTo repair or replace solar panels, first, identify the issue and assess system performance. For minor repairs like loose wires, carefully reattach or replace the faulty components. When it comes to more significant damage, such as cracked or damaged panels, it’s best to seek professional help. Certified solar technicians can safely remove and replace damaged panels while ensuring proper installation.

Tips for Extending the Lifespan
of Solar PanelsBesides regular solar maintenance and inspection, there are a few other ways to extend your system’s lifespan. First, keep panels free from shading by monitoring the surrounding area and removing obstructions. Protect your panels from extreme temperatures by ensuring proper ventilation and using insulation and snow guards when necessary. Handle your system with care during cleaning to prevent damage. You should also invest in high-quality panels and components
