What are the maintenance costs for solar panels/solar system?

Everyone seems to be talking a great deal about how great solar is (and I tend to agree), but I'm not finding a lot of information about how much it costs to maintain solar - like a solar array or solar system...anyone have any info or experience on how much it costs to just maintain a solar system? Many thanks.

    Do you also have to clean them regularly?
  • According to the US Department of Energy, maintenance costs for solar photovoltaic systems are $20 per kilowatt per year on average, although they may rise to $30/kW/yr or $40/kW/yr on some cases. Considering that PV systems now have costs below $4,000 per installed kilowatt, this means that yearly maintenance costs are less than 1% of the system's cost.

    Maintenance is an investment - for example, a solar PV system that isn't cleaned frequently will suffer a drastic drop in performance. A single PV module that is covered with dirt will bring down the production of the entire array!

  • Solar panel maintenance costs can vary greatly depending on each solar provider because system installations are often tailored to the unique energy needs of each homeowner.

    Old thread but nice to know about it, my experience in maintaining a solar panel is different my problem always relies on the battery, every 3 years I need to changed the battery which cost about 50$-100$ depending on the brand.
