How dirt and soiling reduce your solar output in North West England
Panel soiling — the accumulation of dust, pollen, bird droppings, and other debris — is one of the most common and fixable causes of solar energy loss. In arid regions, soiling alone can reduce output by 5–15%. Here's what you should know.
North West England has a cool maritime climate with 3.3 peak sun hoursper day. The UK's cooler temperatures benefit panel efficiency but shorter daylight hours affect annual output.
