Solar Panel Maintenance: What You Actually Need to Do
Solar Panel Maintenance: What You Actually Need to Do
Solar panels have no moving parts and require minimal maintenance. But minimal is not zero. Here is what actually matters.
Regular Cleaning
Dust, bird droppings, and pollution reduce panel efficiency by 5-25% depending on your location. In dusty areas, monthly cleaning during dry season makes a significant difference.
Annual Inspection
Once a year, have a professional check your electrical connections, earthing, inverter performance, and panel condition. Small issues caught early prevent expensive failures later.
Monitor Your Generation
Most modern inverters come with monitoring apps. Check your daily generation regularly. A sudden drop indicates a problem — shading from new construction, a faulty panel, or inverter issues.
When to Call a Professional
If generation drops more than 15% from expected levels, or if you notice any physical damage, discoloration, or error codes on your inverter, get a professional assessment.
