Frequently Asked Questions about Solar Panel Maintenance

Solar Panel Maintenance

Do solar panels need cleaning often?

You should clean your panels once or twice a year for optimal performance, depending on the weather and environment. If you live in a town or city with lots of pollution, dust, or pollen, they may need cleaning more often. Regular cleaning maintains the performance of the panels.

Can I clean my solar panels myself, or should I hire a company?

Cleaning solar panels, yourself is possible if they are within easy reach, but remember to follow safety precautions. Use a soft brush or a sponge and a non-abrasive cleaning product. If your panels are very high up or on a steep roof, it’s best to get a professional in for safety reasons.

What should I do if my solar panels are not generating as much electricity as expected?

If you see a decrease in the power output of your solar panel system, inspect the panels for obstructions caused by tree branches and clear them to improve performance. Also, check for any damage or debris blocking the sunlight. If the problem persists, contact an expert solar company to check the system for technical issues.

Do I need to do any specific maintenance tasks on my solar panels?

Solar panels are low maintenance, but it is good to do some routine checks can keep them in good condition. Regularly look for signs of damage, such as cracks or loose wiring, and fix them. Also, check for dirt and clean the panels if necessary. If available, monitoring your solar panel’s performance through an app can help you spot any issues early on.

How long do solar panels last, and do they come with guarantees?

Most solar panels have guarantees ranging from 20 to 25 years. But they can last well beyond the warranty period, often producing electricity for three or even four decades. It is important to choose high-quality panels with proper installation and maintenance to maximise their lifespan. Regular maintenance and addressing any issues quickly can prolong the life of your solar panel system.

Is it necessary to disconnect the solar panels during maintenance?

You don’t usually have to disconnect the solar panels when doing regular maintenance or cleaning since they work at low voltage, which is safe to handle.

Can I use a pressure washer to clean the panels?

Using a pressure washer to clean solar panels usually is not recommended. High-pressure water can damage the panels’ surface and electrical components. It’s best to use a mild stream of water from a hose and a soft brush or sponge to clean the panels. If there are stubborn stains, consult the manufacturer’s guidelines for appropriate cleaning solutions.

Are there any precautions to take during extreme weather conditions?

Solar panels will withstand most weather, including heavy rain, snow loads, and wind. However, proper installation minimises the risk of damage during extreme weather. You might need structural reinforcement if you live in a place prone to hurricanes, tornadoes, or heavy snowfall.

Should I be concerned about bird droppings on my solar panels?

Bird droppings, although unsightly, do not pose a significant risk to the performance of panels. Rainfall can often take care of little droppings. However, if you notice an accumulation of droppings, clean the affected area with water or a mild detergent solution.

How can I monitor the performance of my solar panel system?

Many solar panel systems come with built-in monitoring to track the output of your panels. These systems provide real-time energy production data to identify performance issues or fluctuations. You can usually find this information through an online portal or phone app. You can track performance with a third-party app if your system doesn’t have a built-in monitoring system.
