Solar Panel Maintenance Checklist

If you have solar panels installed in your home, these are probably the questions you will want answers for!
How do I know if my solar panels need maintenance?
The best way to identify solar panel maintenance issues is to check if the system is generating the optimum energy. Compare your recent electricity bills with those from the previous few months or years to obtain it. Output data is also shown in the monitoring application.
It is a warning sign that your solar panels require maintenance if you find signiïŽcant deviations from the normal or discrepancies in their performance.
You’ll have to do a few basic tasks to maintain your solar panels in good condition, but most of the time, keeping your solar panels is simple and few things you can perform on your own.
Letâs look into some of the important Solar Panel Maintenance checklist
You should always have a maintenance checklist for your solar panels on standby so that you can do timely inspections and identify any defects. Your checklist should include the following:
Visual inspection:

- Debris removal from surface of the panels (such as leaves and nesting material).
- Remove any dust or dirt that has accumulated around the inverter.
- A build-up of dirt in the inverterâs heat sink acts as an insulator, reducing the inverterâs performance and lifespan.
- Whether any of your panels have faded in colour, cracked, or become cloudy, you should contact your provider to see if they need to be replaced.
- Frequency of inspections recommended once in every 6-12 months.
Electrical inspection:
This can be done by a solar maintenance professional to ensure that:
- The earthing point and earth cable are connected and free of corrosion.
- Rooftop isolators are not damaged by heat and the inverter is functioning normally.
Remove potential dangers: PV panels are vulnerable to shading; any overhanging tree branches must be removed to prevent any hazards to the panels. If you notice any trees growing too large since the system was built, cut them down.
Clean your solar panels: Sloping roof installations are generally washed by natural rainfall, although those on flat roofs or in places with drastic pollution or debris need be cleaned at least once in every twelve months; however, this depends:
- pitch of panels.
- proximity to dust sources.
- frequency of rain events.
Track the Performance of Your panels:
Compare performance data with the preceding week, month, and/or the same period last year in order to assess performance. It is recommended to check the performance of your solar panel once in every six months in order to identify issues earlier and fix problems, if required.
Maintaining a logbook:
If you want to keep your solar system in a good condition, it’s always necessary to keep a track of any maintenance work done. This can also include inspecting and cleaning parts, or replacing them if necessary.
You can extend the life and increase the performance of your solar panels by following this simple checklist. Simple upkeep protects your solar investment.
Get your panels serviced â We highly recommend that you do this at least once every year. Solar panels must be maintained in order to last as long and generate energy at a high rate of efficiency.
