Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.

Most homes in Lisnagry benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 74% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
