Solar panels are a smart investment, but like any energy system, they need proper care to work efficiently. If you don’t maintain them, dirt, dust, and weather conditions can reduce their performance over time. But how often do solar panels need to be maintained? And are solar panels expensive to maintain?
How to maintain solar panels is easy because most times, they don’t require much upkeep. With occasional cleaning and regular inspections, you can keep them running smoothly for years. Whether your solar panels are on the roof or ground-mounted, understanding the right maintenance steps will help you get the most value from your system.
In this blog post, we’ll explore how to maintain solar panels, factors that affect their lifespan, and whether the cost of maintaining them is something to worry about but first, let’s look at how often you should do a maintenance routine on your solar panel.
Do Solar Panels Require Regular Maintenance?
When properly installed, solar panels don’t need frequent maintenance to keep generating power safely. However, scheduling a maintenance inspection every 12 to 18 months helps ensure your system runs efficiently throughout its 25 to 30-year lifespan.
During an inspection, a licensed electrician cleans the panels, checks for obstructions, tests connections and switches, and ensures everything is working as it should.
It’s also important to note that solar panels can sometimes develop issues without showing immediate signs. If left unchecked, this could lead to unexpected spikes in your electricity bill. When solar panels develop a fault or lose efficiency due to dirt, wiring issues, or inverter malfunctions, they generate less power. As a result, your system pulls more electricity from the grid to compensate, increasing your energy costs. Regular maintenance helps prevent this by ensuring your panels operate at full capacity.
How Often Do Solar Panels Need to Be Maintained?
Regular maintenance is essential to keep your solar panels functioning at their best. In most cases, solar panels require cleaning at least twice a year to remove dust, dirt, and debris that can block sunlight. However, the frequency depends on several factors. If you live in an area with high levels of dust, pollen, or pollution, you may need to clean your panels more frequently. Likewise, regions with heavy rainfall might require less maintenance, as rain can naturally wash away dirt.
Weather conditions also play a role. If you experience long dry spells, debris can accumulate faster. Similarly, if you have trees nearby, falling leaves, bird droppings, or sap can reduce the efficiency of your solar system, requiring more frequent cleaning. Regular inspections can help you determine the right maintenance schedule based on your environment.
How to Maintain Solar Panels on Roof
When your solar panels are installed on the roof, maintaining them requires extra care to ensure safety and efficiency. The first rule of rooftop solar maintenance is to use safe cleaning methods. Here’s how you can do that:
- Use mild soap and water for cleaning. The harsh chemicals in some soaps can damage the surface of the solar panel.
- Use a soft brush or non-abrasive sponge for scrubbing because it prevents scratches on the panel’s surface.
- A long-handled tool or hose with a gentle spray for reaching high areas is great because it helps clean hard-to-reach spots without climbing onto the panels.
- Use distilled water for the final rinse because it prevents mineral deposits and streaks.
- Clean in the early morning or evening. This prevents quick evaporation, which can leave cloudy lines on the solar panel.
Safety Tips
Cleaning solar panels on the roof can be risky, so it’s important to take precautions:
- Use a stable ladder and wear slip-resistant shoes for safety because it reduces the risk of falls.
- Have someone nearby for assistance because it ensures quick help in case of an emergency.
- Avoid walking on panels because they are fragile and could crack under pressure.
- Call a professional for maintenance if you’re uncomfortable working at heights, because safety is always a priority.
Are Solar Panels Expensive to Maintain?
One of the biggest concerns about solar panels is maintenance costs. Fortunately, maintaining solar panels is relatively affordable compared to other home energy systems. On average, professional cleaning service depends on the size of your solar array and accessibility. However, if you choose to clean them yourself, the cost is minimal, just the price of cleaning materials and your time.
Regular maintenance can actually save you money in the long run. By keeping your panels clean and free from debris, you ensure maximum energy output, reducing your electricity bills. Neglecting maintenance, on the other hand, can lead to reduced efficiency and even long-term damage, which could result in costly repairs or replacements.
If you’re trying to decide between DIY and professional maintenance, consider the risks involved. While DIY cleaning is cheaper, it requires effort, time, and safety precautions. Professional maintenance, though slightly more expensive, ensures thorough cleaning and early detection of potential issues that might go unnoticed.
Maintaining Solar Panels: Best Practices
To extend the lifespan and performance of your solar panels, follow these best practices:
- Regular cleaning: Remove dirt, dust, and bird droppings at least twice a year.
- Monitor energy output: Use a monitoring app to track performance changes.
- Check for damage: Look for cracks, loose wiring, or broken parts.
- Trim nearby trees: Prevent excessive shading that reduces efficiency.
- Keep panels free from snow and debris: Ensure uninterrupted energy production.
- Schedule professional inspections: Detect potential issues early before they escalate.
Monitoring tools or apps can also help you track your system’s efficiency in real time, alerting you to any significant performance issues.
