Your solar panels aren't working as well as they used to. What can you do to improve their performance?

1 Clean your panels

One of the simplest and most effective ways to boost your solar panels' performance is to keep them clean. Dust, dirt, bird droppings, and other debris can accumulate on the surface of your panels and block some of the sunlight from reaching the cells. This can reduce the output and efficiency of your system by up to 25%. To clean your panels, you can use a soft brush, a hose, and some mild soap. Avoid using harsh chemicals, abrasive materials, or pressure washers that can damage your panels. You should also check the manufacturer's instructions and warranty conditions before cleaning your panels. Ideally, you should clean your panels at least once or twice a year, or more often if you live in a dusty or polluted area.

4 Upgrade your components

Another option to improve your solar panels' performance is to upgrade some of your components to newer or more efficient models. For example, you can replace your old or faulty inverter with a more advanced one that has a higher conversion rate and better features. You can also add optimizers or microinverters to your system that can increase the output of each panel individually and reduce the impact of shading or mismatch. You can also install a battery storage system that can store the excess energy you generate and use it later when you need it. Upgrading your components can increase your system's performance, resilience, and value, but it can also be costly and complex. You should consult with your installer or service provider and weigh the benefits and drawbacks of each option.

5 Maintain your panels

Finally, one of the best ways to improve your solar panels' performance is to maintain them properly and regularly. Maintenance can help you prevent or fix any issues that might affect your system's operation and safety. You should inspect your panels for any cracks, chips, or corrosion that might damage the cells or the glass. You should also check the wiring, connectors, and mounting systems for any loose, broken, or worn parts that might cause electrical or fire hazards. You should also follow the manufacturer's recommendations and schedule for maintenance and service. You should also keep a record of your system's performance, maintenance, and warranty details. Maintaining your panels can help you extend their lifespan and ensure their optimal functioning.
