Signs Your Residential Solar Panels May Need Repair

How to Detect and Address Solar Panel Issues for a Longer Lifespan

As homeowners, we invest in solar panels to reduce our dependence on non-renewable energy sources and to save money on electricity bills. However, solar panels can develop issues over time like any other appliance.

As solar energy becomes more popular, homeowners should understand the importance of detecting and addressing potential issues to keep their panels functional and efficient. This blog will highlight ways to detect and address solar panel issues to extend their lifespan and performance.

Physical Damage

Solar panels can sustain physical damage from weather events, such as hailstorms or high winds. A common sign of physical damage is cracks on the panel's surface. Homeowners can also check for discoloration and broken glass.

If physical damage is detected, contacting a professional technician for solar panel repair is necessary to repair the damage properly. Attempting to repair physical damage alone can cause further damage and void your warranty.

Dirty Panels

Dirt and debris can accumulate on solar panels, reducing their power output by up to 25%. Upkeep is important, so contact your solar installation company to regularly to keep them free of dust, leaves, and bird droppings. Solar panels can be cleaned using a soft-bristled brush or a cleaning solution recommended by the manufacturer. In most cases, the technicians will have access to materials necessary to upkeep maintenance.

Faulty Wiring

Faulty wiring is another issue that can reduce solar panel performance. Homeowners can detect faulty wiring by checking the junction box on the back of the panel or the inverter. If these components show signs of rust or damage, you may need to contact a professional to replace them. It would be best never to attempt to repair electrical issues independently, as they can be dangerous and potentially deadly.

Inefficient Inverter

The inverter converts the DC power generated by solar panels into AC power used by households. Inverters are prone to faults and may need replacement after a few years. You can detect faulty inverters by checking if the AC power output is less than expected. If the inverter is not working efficiently, it can cause damage to the system and reduce the panel's lifespan.

Shading Issues

Shading is a common issue that reduces solar panel efficiency. Even one partially shaded panel can decrease the system's output by 50%. A professional installation technician will ensure that your solar panels are installed in areas that receive maximum sunlight and are free from shading issues caused by nearby trees or buildings.


Corrosion can occur on the metal frame holding the solar panel. Homeowners can detect corrosion by checking for rust or staining on the frame. If corrosion is detected, it must be addressed immediately, as it can lead to structural damage and impact the panel's performance.


Regular maintenance is essential to extend the lifespan of solar panels. Homeowners should inspect their panels regularly for any signs of damage or issues. They should also schedule yearly maintenance visits with a technician to check for problems and ensure the system runs efficiently.
