Frequently asked Questions
Is pressure washing safe for solar panels?
No, pressure washing is not safe for solar panels because the high pressure can damage the glass, seals, and coatings, leading to reduced efficiency and potentially voiding the warranty. It is safer to use a normal garden hose with a gentle spray or a soft brush and water to clean them.
What is the best way to clean solar panels?
Yes, you absolutely need to turn off your solar panels before cleaning them to prevent electric shock, especially since they can generate electricity even when not at peak performance. It is a crucial safety step, along with following the manufacturer's specific shutdown procedure, to avoid electrical hazards
How much does it cost to clean solar panels in Australia?
The average cost of a clean varies, it depends on if the house is single or double story, the size of the system, slope of the roof and the type of roof
Do solar panels require cleaning?
Yes- If you don't clean your solar panels, they will produce less electricity, leading to lower efficiency and potentially reduced savings on your energy bills. A build-up of dirt, dust, bird droppings, or other debris can block sunlight from reaching the solar cells, causing a drop in power output that can range from 5% to over 30% in severe cases. While rain helps, it's often not enough to remove all grime, especially in dusty areas or on flat panels.
How often should solar panels be cleaned?
Solar panels should ideally be cleaned once or twice a year. However, the optimal frequency depends on your location and environment, so you may need to clean them more often if they are in a dusty area, near a busy road, under trees, or on a flat roof. If you are unsure, a professional service every two years is a good way to ensure they are maintained correctly.
