What should I do if I don't have solar system monitoring?
If you do not have solar system monitoring installed, the first step is to check for any obvious issues with the solar panels, such as a build-up of dirt, dust, mould, or leaves. Maybe a good wash with a soft broom and water is all that they need. Also, check no nearby trees have grown significantly and are shading the panels.
Can you clean solar panels on a roof?
Cleaning solar panels should be done using only water and a soft broom. Solvents and harsh detergents should NOT be used to wash the surface of solar panels, as this can lead to water ingress and may void the manufacturer's warranty. Note that cleaning solar panels on a roof can be very dangerous, so using a certified solar professional is advised.
How do you clean a solar panel?
Any mould or lichen growth should be removed using water and a soft brush. To reduce the adverse effects of dirty solar panels, it is recommended that panels be thoroughly cleaned at least once a year or more frequently in dusty environments. Cleaning solar panels should be done using only water and a soft broom.
How can a homeowner reduce a high grid voltage problem?
If options 1 and 2 are problematic or too difficult, the easiest way for a homeowner to reduce high grid voltage issues is to self-consume as much solar energy as possible. Increasing self-consumption will reduce the amount of solar being exported and thus reduce the grid voltage; it will also help save money by using less energy from the grid.
