- Panels should be cleaned of dust, dirt, leaves, and bird droppings, which can block sunlight and reduce efficiency. For areas with heavy pollution, pollen, or frequent dust, more frequent cleaning may be necessary.
- In most cases, twice a year is adequate, but regions with specific environmental conditions may need monthly cleaning.
- Use a soft brush or cloth with water, avoiding abrasive materials or harsh chemicals that could damage the panels. In some cases, professional cleaning may be needed.
- Inspect panels for cracks, discoloration, or any physical damage that could impact performance.
- Ensure that all bolts, brackets, and racks are secure and have not shifted due to weather or time.
- Check for any new sources of shade that could impact energy production, like tree growth or new structures.
- Look for any signs of wear, corrosion, or loose connections in the wiring. Faulty wiring can lead to efficiency losses or safety risks.
- Verify that the grounding system is intact to prevent electrical hazards and equipment damage from power surges.
- Since inverters handle high current and voltage, they may wear down faster than other system components. Regularly inspect for any error messages or abnormal performance, and replace as needed (inverters generally last around 10-15 years).
- Check the capacity and health of the batteries if the system includes energy storage. Over time, batteries may degrade and lose efficiency, requiring eventual replacement.
- Inspect terminals and connections for corrosion or wear, and clean if necessary.
- Ensure batteries are stored in a cool, dry place to prevent overheating, which can reduce lifespan.
- Review data regularly to check for any dips in performance. Many systems come with digital monitoring that tracks energy production, allowing you to detect issues early.
- Track expected seasonal variations to identify any unusual performance drops that may indicate an issue with the system.
- Having a professional inspect the system annually or bi-annually helps catch any issues that might not be immediately visible. They can perform in-depth electrical tests, inspect panel alignment, verify inverter efficiency, and check structural components.
- After severe weather events like heavy storms, hail, or high winds, inspect the system for any physical damage. Strong winds and hail can damage panels, while lightning can affect wiring and inverters.
- Regular maintenance also includes reviewing and keeping records for warranty purposes. Many warranties require proof of regular maintenance for coverage in case of repairs or replacements. while lightning can affect wiring and inverters.
