  • Panel Maintenance: If your panels are mounted at an elevation of over 12 degrees from horizontal, they usually don’t require special maintenance. Rain generally keeps them clean, and a monitoring system alerts you to any potential issues. However, occasional visual inspections should be performed to ensure there’s no debris or shading affecting performance.
  • Solar Panel Cleaning: While rain helps keep panels clean, regions with minimal rainfall might benefit from occasional cleaning. Use a soft brush, gentle detergent, and a hose to remove dust and dirt. Avoid abrasive materials that could scratch the panels.
  • Tree Trimming: Trim any overhanging branches that may cast shadows on your solar panels. This ensures maximum exposure to sunlight throughout the day.
  • Inverter Upgrades: If your home solar system has been in operation for several years, consider checking for inverter upgrades. Newer models may offer improved efficiency and better monitoring capabilities.
  • Shade Analysis: Periodically assess your solar panels for any new sources of shading, such as growing trees or neighboring structures. Addressing shading issues promptly ensures consistent energy production.
  • Solar Panel Lifespan: While solar panels are durable, they have a lifespan. Keep track of your panels’ age and plan for replacements or upgrades as technology advances.

Leveraging Batteries for Optimal Energy Use
