How do I know if my solar panels have a fault?
If you believe your solar panels have a fault or the performance has noticeably decreased, there are several ways you can diagnose a problem. The first step is to visually check the solar panels for any signs of failure or dirt build-up, which can often result in mould growth and lead to poor performance.
