6 FAQs about [Signs of poor solar cell performance]
How do I know if my solar panel is bad?
If you notice that your solar panel is not producing as much energy as it used to, it could be a sign that something is wrong. Another sign to look out for is physical damage to the panel, such as cracks or scratches. In some cases, a bad solar panel may also cause your inverter to display an error message.
