How to Maintain Solar Panels: Tips and Tricks

For the solar panels and cells to last longer, you must clean them at least 2-4 times a year. If your solar panels are tilted, it is easier for the rains to flush off the debris from the panels. However, you cannot always be that lucky.

During the dry season, you must clean the panels manually to clear off the surface’s dust and dirt. Here are a few cleaning and maintenance tips for your solar panels that will keep them in top condition:

Maintenance of Solar Panel

• Servicing: It is advisable to get your solar panels serviced at least once a year to be safe from situations of faulty performance.
• Inverters: The life expectancy of the inverters is no longer than that of the panels. Hence, you may have to keep an eye on their proper functioning.
• Documentation: It is vital to note the everyday energy production of the panels to improve their subsistence. Also, do ensure that you follow this on cloudy days without fail.
• Avoid Shading: For acquiring higher performance results and energy production, you should avoid placing the panels under the shade. This step is needed for the maximum sunlight absorption to generate enough electricity for your house.

Cleaning Tips for Solar Panels

• Cleaning Kits: A solar panel cleaning kit is perfect for maintaining the cleanliness of your solar panels at all times. You will find a small brush, wiper, and biodegradable soap. You can follow the instructions provided for cleaning the panels seamlessly.
• Avoid Harsh and Abrasive Materials: It is advisable to avoid these materials to protect the panels from damage, such as a scratch. Make use of soft cloth and rags for smooth cleansing of the panels.
• Avoid Hot Water: To clean the panels, you should avoid hot water since they are tempered glass and can break.
• Long Handle Wipers: For your convenience, you should use a wiper with long handles to help you reach the corners of the panels.

Do Solar Panels Require Repairs and Replacements?

Usually, solar panels come with a warranty of 25-30 years, and many manufacturers offer this to their customers. Repair and fixing costs may be needed if any part of the solar panel stops functioning or is subjected to wear or tear. So, what should be your next step if this happens?

It is recommended to contact a professional who can fix any damage your solar panels face. If the solar panel inverter fails to support the system, it may need fixing, for which you may have to spend around £500-£1,500 to replace them.

If you presume any fault in the grid or the panels are broken, you should report this to an engineer or your solar service provider to fix it immediately. However, if you take good care of the solar panels, you can avoid this hassle and save extra pounds from repairs.

How to Know If Your Solar Panel is Faulty?

Even though solar panels are known for their low maintenance, they may require repairs and replacements from time to time. However, what qualifies for repairs and faults in solar panels?

Discolouration of Solar Panels

Discolouration or snail trails in solar panels often happen after years of usage. This usually occurs when a defective silver paste is used for the manufacturing process of the panel. Snail trail often leads to minute cracks on the panels and gravely affects the performance of the solar panels.

Inverter Issue

Most solar panels have a longer expectancy of 30 years; however, that is not the case with the inverters. If you face any energy shortage on any typical sunny day, the reason could be your inverter.

It would be best to avoid overheating; you keep the solar panel inverters in a well-ventilated box. This pointer is highly crucial for maintaining the endurance of the inverter. Keep the inverters clean, as dust and dirt may clog up the vents, resulting in overheating.

The inverters usually last up to 10 years, and any fault detected should be reported to a professional.

Cracks and Tears

Small cracks and breaks can occur on the surface of the solar panels during the production or shipping of the panels. Though micro-cracks may not lead to significant energy loss, they may have severe repercussions in the future.

In cases of more significant cracks on the panels, it may cause considerable energy loss and may result in lower performance of your solar panels. It could also interfere with the daily electricity generation and affect your everyday routine.

Dark Spots

Solar panels are made both air-tight and water-tight by laminating the glass layer and solar sheets. However, if this is not done correctly, the solar panels may have gaps for the air or water to enter them.

It can spread darker spots around the panels due to internal corrosion. It would ultimately hamper the energy production of solar panels and reduce their efficiency immensely.
