Maintenance

Summary:

  • Solar electric systems have no moving parts and therefore require very little maintenance
  • Usually the only thing solar panels may need is a periodic cleaning if they are dirty, perhaps a couple times per year.

Detail:

One of the reasons solar electric systems last so long is that they have no moving parts, nothing to wear out over time. The surface of the solar modules receive the most beating by the sun, but this is exactly how they were designed to operate.

For that reason, there is virtually no maintenance required unless you experience a specific production issue. On occasion you might find it necessary to spray the panels off with a hose once or twice each year, but usually there is enough rain to keep them as clean as they need to be to perform optimally.
