Solar panel maintenance
Official studies show that dirt build-up on your solar panels can adversely affect their performance. This dirt can be anything from leaves, dust, pollen, bird droppings, to calcium- and salt build-up from being exposed to the elements. Rainwater and wind will only provide a limited amount of cleaning to your solar panels. Sometimes moss and weeds may even grow around your solar panels.
Cleaning your solar panels with soap and water can damage them and have an adverse effect on their performance. Solar panels should be cleaned with purified water which leaves no residue. This will help maintain their performance and ensure you continue to derive the maximum benefit from them.
