The best approach for cleaning involves using a soft brush or sponge and gentle soapy water. Avoid chemical solutions that can harm the panels. Ensure safety protocols are followed when accessing the roof or installation area. Maintaining clean solar panels maximizes light absorption and boosts energy production.

5. ASSESS SHADING IMPACTS

Solar arrays need unobstructed sunlight to function effectively. Assessing the surroundings is essential; ensure no new obstructions, like overgrown trees or newly constructed buildings, are casting shadows over the panels. Seasonal changes may affect sunlight exposure, drastically controlling energy output.

Shading can create “hotspots” on solar panels, causing malfunctions. Ensuring adequate sunlight exposure can mean relocating the panels or pruning surrounding foliage. Implementing this preventive measure guarantees uninterrupted energy production over the lifespan of the solar system.

6. DETERMINE THE CONDITION OF THE BATTERY

In systems utilizing battery storage, the battery’s condition may significantly impact overall performance. A faulty or nearly depleted battery can lead to the system’s inability to operate efficiently. Regularly monitoring the battery voltage ensures it is charging properly when solar energy is produced.

If the battery condition deteriorates, it can severely limit the ability of the solar panels to light up. Consideration should also be made for battery lifespan, which can vary based on cycling and maintenance. If the battery has reached the end of its operational life, replacement should be undertaken promptly to restore full system functionality.
