Solar panels are devices that directly convert sunlight (solar energy) into electrical energy based on the photovoltaic effect. Free electrons will move between the electrodes, generating electric current.

The junction box at the back of the solar panel is where the generated electrical energy is collected and transferred out. In unfavorable working conditions such as shading, prolonged dust accumulation, or equipment failures, and natural events like lightning strikes can lead to junction box damage or damage to the solar panels. Damaged solar panels, if not addressed, can significantly reduce the performance of the panel arrays, posing a risk of system explosions.

Common Issues with Solar Panels

Physical Damage

Harsh weather conditions can cause damage to solar panels. From hail to strong winds, natural factors can impact the integrity of solar panels. While solar panels are manufactured to withstand such weather, it is crucial to check for any potential damage after severe weather events.

Shading

Solar panels need unobstructed exposure to sunlight to operate efficiently. However, new structures or the growth of greenery can create shadows, affecting the efficiency of solar panels. It is essential to notice and manage new shading sources promptly to maintain system performance and optimize operating costs.

Deterioration

While solar panels are designed to endure for decades, system components may deteriorate over time. The inverter, connectors, or wiring system may need replacement or repair to ensure the optimal operation of the system.

Electrical Issues

Less common but potentially more serious are electrical issues. These problems can range from minor issues with the wiring system to more severe issues like inverter faults. Regular checks can help identify and address these issues before they significantly affect your system’s performance.
