How often should I clean my solar panels?
In the UK this is something that we do not have much experience or knowledge with. Luckily solar panel cleaning services in other countries have been established for many years and many recommend getting them cleaned twice a year. Some suggest you get them cleaned every couple of months.
For the best results the first clean should be at the start of spring as the days lengthen and the amount of sun reaching the panels increases. Later in the summer they should be cleaned again. For the UK climate this seems to be the best solution.
