The following may or may not affect your costs:

  • Size
  • Proximity to Contractor
  • Maintenance Agreement
  • Level of Build-up
  • System Location

Solar Panel Maintenance and Inspections

The solar systems typically will not demand much care all throughout their lifetime but

cleaning is the primary concern. They will typically come with a monitoring option where

you would be able to watch and measure yourself. Because of this monitoring ability, you

would be able to catch the dips in energy output and identify equipment failures right away.

The best way to make sure that the problem is solved correctly once you identify that there

is a problem, is to get it inspected by a local professional.

An annual inspection usually could cost you an average of $150 because the contractor will

check important components, search for corrosion, wear and loose wiring and bolts. The

inspectors may or may not find cracks in your panels or broken glass and they would suggest

repair work or replacement which would cost you an average of $650.

Maintaining Your Solar Energy System

    DIY Cleaning Costs

Using an extended, water-fed window washing pole would have to be the safest way to

wash your equipment from the ground. You have to make sure that you are using the

right soap for optimizing the energy output which would lead to little to no residue and

cause damage or wear. The water-fed poles typically cost about $500 to $5,000, water-fed

brushes are around $80 to $175 and soap is usually around $30 to %50.

Some solar experts say that you only would need a hose and a soft sponge and some soap

to accomplish this task, but the best thing you could do is contact your installer for their

recommendation since they know your solar system more than anyone else. Using the

wrong tools could lead to damaging your panels and voiding warranty.

Cleaning systems usually look like sprinklers and it could be programmed to wash and

rinse at the frequency you need. One of the leading brands in this market would have to

be the Heliotex which has products that are compatible with any size and any brand of


Cleaning robots have the capacity to wash your panels daily. They could do it with or

while the others are scrubby autonomous robots. There are also some cleaning robots

that run on solar energy.

  • Equipment- This would cover the components of the solar panel, like when the inverter and panel fail.
  • Performance- This would ensure that your system will operate at a certain level of efficiency throughout its lifetime
