Solar Panel Maintenance: The Do’s and Don’ts for Homeowners

Investing in solar panels is not just about reducing your carbon footprint and saving money on energy bills; it’s also about ensuring that your solar energy system operates efficiently for years to come. Proper maintenance is key to maximising the performance and lifespan of your solar panels. In this blog post, we’ll outline the essential do’s and don’ts for solar panel owners, helping you keep your system in top condition and reap the full benefits of solar energy.


  1. Regular Inspections:
    • Do inspect your solar panels regularly, ideally at least once every six months, to check for any signs of damage or debris accumulation. Look for cracks, chips, or discoloration on the panels, as well as any loose connections or mounting hardware.
    • Do schedule professional inspections annually to ensure that your solar energy system is functioning optimally. A qualified technician can identify any potential issues early on and address them before they escalate. Solar Voltaics offers a domestic maintenance package.
  2. Keep Panels Clean:
    • Do clean your solar panels periodically to remove dirt, dust, pollen, bird droppings, and other debris that may accumulate on the surface. Dirty panels can reduce energy production by blocking sunlight, so regular cleaning is essential for optimal performance.
    • Do use a soft brush, sponge, or cloth along with water to gently clean the panels. Avoid using abrasive materials or harsh chemicals, as they can scratch or damage the panels.
  3. Trim Surrounding Vegetation:
    • Do keep trees, branches, and foliage trimmed to prevent shading of your solar panels. Shading can significantly reduce energy production, so it’s essential to ensure that your panels have unobstructed access to sunlight throughout the day.
  4. Monitor Performance:
    • Do monitor the performance of your solar energy system regularly using monitoring software or tools provided by your solar panel installer. Keep track of energy production levels and be on the lookout for any significant deviations from expected output, which could indicate underlying issues.


  1. DIY Repairs:
    • Don’t attempt to repair or modify your solar panels yourself, especially if you’re not trained or experienced in solar panel maintenance. DIY repairs can void warranties and may result in further damage to your system or even personal injury.
    • Don’t hesitate to contact your solar panel installer or a qualified technician if you notice any issues with your solar panels. It’s better to seek professional assistance than to risk causing more harm by attempting repairs on your own.
  2. Use High-Pressure Water:
    • Don’t use high-pressure water or pressure washers to clean your solar panels, as they can damage the panels’ delicate surface and protective coatings. Stick to gentle cleaning methods using a soft brush or cloth to avoid causing any harm to your solar panels.
  3. Ignore Warning Signs:
    • Don’t ignore any warning signs or unusual behaviour from your solar energy system, such as sudden drops in energy production or abnormal noises. These could be indications of underlying issues that require attention from a qualified technician.
    • Don’t wait until a minor problem escalates into a major issue. Addressing potential issues promptly can save you time, money, and headaches in the long run.
  4. Neglect Regular Maintenance:
    • Don’t neglect regular maintenance of your solar panels, assuming that they will continue to operate flawlessly without any upkeep. Routine maintenance is crucial for preserving the performance and longevity of your solar energy system.
    • Don’t overlook the importance of professional inspections and servicing. Investing in regular maintenance can extend the lifespan of your solar panels and maximise your return on investment over time.

By following these do’s and don’ts for solar panel maintenance, you can ensure that your solar energy system operates efficiently and reliably for years to come. Regular inspections, proper cleaning, and timely repairs are essential for maximising energy production and prolonging the lifespan of your solar panels. Remember, when it comes to solar panel maintenance, an ounce of prevention is worth a pound of cure. Take care of your solar panels, and they’ll take care of you, providing clean, renewable energy for years to come.
