Solar System Maintenance Checklist

Investing in a solar system is a huge decision, with setups often costing hundreds of thousands of pounds. Despite this, it can be a drastic cost-saving action that gives businesses the lifeline to remain competitive in the market.

Not maintaining this system, after spending a considerable amount on it, is a risk. A solar system is expected to lose efficiency over its 25 year lifetime, called degradation. 

There are variables that cause a system to degrade more over time. With maintenance, these variables are kept in check and your system is able to generate as much electricity as possible. Saving you the maximum money. 

Solar System - Health Checklist

Use our comprehensive guide to see what maintenance of a solar system entails.
Warning: please do not begin any electrical work without the correct qualifications, training and PPE.

1. Visual inspection
of pv modules

  • Check for any visible signs of damage, dirt, debris, or shading on the panels.
  • Ensure there are no cracks, discoloration, or delamination on the solar panels.

2. Monitoring system performance

  • Use the system’s monitoring software to check the energy production levels
  • Compare daily performance data to historical data for the same day to identify any discrepancies.

3. Inspect inverters

  • Check for any error messages or warning lights.
  • Ensure the inverter is operating within the normal temperature range.
  • Verify that the ventilation around the inverters is not obstructed.

4. Check for
vegetation growth

  • Monitor and manage vegetation around the solar array to prevent shading.
  • Trim any overgrowth that could cast shadows on the panels.

5. Cleaning of Solar Panels

  • Depending on the location, solar panels may need to be cleaned to remove dust, bird droppings, or other debris that could affect performance.
  • Use a soft brush or cloth and mild detergent if necessary; avoid abrasive materials.

6. Inspect Mounting
and racking system

  • Check for any loose bolts or structural weaknesses.
  • Ensure that all mounting points are secure and that there is no corrosion.

7. check electrical systems

  • Inspect wiring, connectors, and junction boxes for signs of wear, damage, or corrosion.
  • Ensure that all electrical connections are tight and secure.

8. Review energy
production and consumption

  • Analyze the system’s energy production data in detail.
  • Compare the actual energy production to the expected output for the season.
  • Adjust system settings if necessary to optimise performance.

9. Comprehensive system check

  • Conduct a thorough inspection of the entire system, including panels, inverters, mounting hardware, and electrical systems.
  • Replace any worn or damaged components as necessary.

Comprehensive Record keeping

  • Maintain a detailed maintenance log for all inspections, cleanings, and repairs. This log can help in identifying trends, planning future maintenance, and resolving warranty issues.

If you have any questions about any of the checks listed above, please don’t hesitate to reach out for guidance and insight. 
We’d be happy to advise what is needed, and included as part of any of the health check items.
