The installation of residential solar panels is a significant investment that promises long-term benefits, including reduced electricity bills and a smaller carbon footprint. To ensure that your solar panels continue to operate at peak efficiency and provide you with the maximum return on investment, proper maintenance is crucial. In this blog post, we will explore a comprehensive set of maintenance tips to help you keep your residential solar panels in optimal condition.

Regularly clean your residential solar panels

Solar panels are exposed to various environmental elements, such as dust, pollen, bird droppings, and pollutants, which can accumulate and reduce their efficiency. Regular cleaning is essential to remove these contaminants. Use a soft brush or sponge and a gentle detergent to avoid scratching the surface of the panels. Cleaning should be done at least twice a year or more frequently if you live in an area with high pollution or bird activity. You can find a solar panel cleaning or roof cleaning service in your area that will be able to do this for you. 

Monitor for shading and keep surrounding vegetation in check

Shading can significantly impact the performance of solar panels. Even partial shading on a small portion of a panel can reduce overall system efficiency. Regularly monitor your panels to ensure they are not shaded by nearby trees, buildings, or other obstructions. 

When installing your residential solar panels, The Little Green Energy Company takes shading into account, as well as the angle of the sun and any other potential obstructions. You should not have to worry about shading, but it is worth keeping in mind in order to ensure optimal efficiency of your solar panels. 

Ensure that trees and bushes around your solar panels are well-maintained. Overhanging branches can drop leaves, debris, or sap onto the panels, reducing their efficiency and requiring more frequent cleaning. Trim any vegetation that may cast shadows on the panels during peak sunlight hours.

Check your solar panels for damage

Checking your residential solar PV system for damage is a good idea to be doing regularly, much like you would check on any LCD display. Checking your solar panels for visual signs of damage is the best way to identify obvious issues. If your residential solar panels do appear to be damaged, you can always get in touch with our friendly team of experts. 

Update firmware and software 

Many modern solar panel systems come equipped with monitoring software that allows you to ensure that everything in your system is running smoothly. It is common for monitored systems to automatically update software and firmware so you will always have access to the best information about your system. If you have a Tesla Powerwall linked to your solar panel system you can monitor the whole energy ecosystem in your property through the Tesla App, and Tesla will frequently update their system to keep it working to the very best standard.

Protect your solar panels against wildlife

Birds, rodents, and insects may be attracted to the space beneath solar panels for nesting or shelter. Use mesh or other deterrents to prevent pests from nesting beneath the panels, as their presence can lead to a build-up of debris and potential damage.

Schedule professional inspections

While regular homeowner inspections are beneficial, it’s essential to schedule periodic professional inspections. The qualified technicians at TLGEC can conduct a thorough examination of your solar panel system, checking for issues that may not be immediately apparent to the untrained eye. Professional inspections and servicing can catch potential problems early on and ensure the continued efficiency of your solar panels.
