Solar panels are remarkably low-maintenance, but some basic care can significantly improve their efficiency and lifespan. Here are our top tips from 22 years of experience in the solar industry.
Regular cleaning is the most important maintenance task. Dust, bird droppings, and pollen can reduce panel efficiency by 15-25%. We recommend cleaning your panels every 2-3 months, or more frequently during dry, dusty seasons.
Use a soft brush or sponge with plain water to clean panels. Avoid harsh chemicals or abrasive materials. Clean early in the morning when panels are cool to prevent thermal shock and to avoid quick evaporation that can leave residue.
Check for shading issues periodically. New tree growth, buildings, or other obstructions can create shadows that significantly reduce output. Even partial shading of one panel can affect the entire string's performance.
Monitor your system's performance through the inverter display or monitoring app. A sudden drop in generation could indicate a technical issue that needs professional attention.
Arrow Power Controls offers annual maintenance packages that include panel cleaning, electrical inspection, inverter health check, and performance optimization. Our AMC customers typically see 10-15% better output compared to unmaintained systems.
