Recommendations can vary depending on your specific circumstances however we do encourage regular cleaning of the panel array. Any build-up of grime, leaves, or debris can impact the overall performance of the system. How often you arrange for the panels to be cleaned may depend on how dirty they get. Sometimes a monthly clean might be too excessive whereas quarterly or bi-annual cleaning routines may be more realistic. If you prefer to clean the panels yourself stick with soft sponges and mild detergents because anything too strong might damage the panels and equipment.
In addition to cleaning it pays to have someone physically check on the appearance of the panels for any signs of cracks or other damages. Sometimes the rack mounts, wires, and isolation switches can be compromised by water ingress or even tampered with by wild animals or third parties. Prevent a major incident by staying on top of solar panel system inspections.
How often are you checking the inverter? Daily, weekly, monthly? Check it as often as possible to ensure it is working. Keep track of the performance data and call for professional assistance if you cannot isolate a potential fault.
To summarise, commercial solar PV systems do require maintenance and regular check-ups although you can run with minimal checks in place. We highly recommend regular inspections and cleaning regimes to ensure you get the most out of your investment.
