How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?
Maintenance Of Solar Panels
I'm okorder /... . That means that not only do they guarantee the panel won't completely die, they guarantee that it will deliver a certain amount of power. That suggests that manufacturers expect most panels to last longer than 25 years. Our panels have been up a little over 5 years - no trouble yet. In a dirty location, or where the panels are mounted flat, occasional cleaning may be required. In many place, the morning dew and slant of the panels is enough to keep them clean. In my limited experiments with our panels, I saw little difference in power production between a panel that appeared dingy to the eye, and one that was just cleaned. There is a component called an inverter used in most solar power systems. That generally has a warranty of 0 years, so expect it to break after 5, to be replaced at a cost of a few thousand dollars. Or maybe repaired for less. The kind of solar power popularly installed today does not use batteries. Batteries are generally only for remote installations that did not have grid power when the solar was first put up.

New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
