The most common issues include wiring and connection problems, shading from trees or buildings, dirt and debris on panels, and faulty inverter performance.
You can diagnose faulty wiring issues by checking for any visible damage to cables, ensuring all connections are secure, and using a multimeter to test voltage levels at different points in the system.
Shade can significantly reduce the efficiency of solar panels by blocking sunlight, which can lead to decreased energy production. Even partial shading can cause issues, as it affects the overall power output of the system.
You should evaluate factors such as the amount of direct sunlight your panels receive, potential obstructions like trees or buildings, and seasonal changes in sun position that may cause shading.
You can utilise technology by installing monitoring software or apps provided by your solar panel manufacturer, which allow you to track system performance, receive alerts for any issues, and analyse energy production over time.
