Energy generated from solar panels has a negative carbon footprint, meaning it produces no emissions and, at the same time, offsets the need for power production from other fossil fuel sources. Government climate action incentives are continuing to encourage more homeowners to install solar panels on their roofs.

Whether you have them already installed, or are thinking about doing so, it’s important to know how to maintain them to protect your investment, reduce loss, and keep them producing power efficiently.

Maintenance tips

  • Clean solar panels will produce the most energy. Check panels monthly and remove leaves, dust and dirt from their surface. Clean the front of panels using a hose or a soft sponge.Cleaning Solar Panels-510568553.jpg
  • Keep panels free from shade. Shading or blocking of any part of the panel can cause arcing (or sparking) in the wiring. Trim back tree branches, vines and large bushes that may block sunlight from reaching the surface of the solar panels.
  • Snow may accumulate on panels during the winter. Carefully clear away the snow if it does not melt away on its own.
  • Don’t ever stand on solar panels. Standing on the panels can cause cracks in the glass, photovoltaic material, or weatherproof seals. This will result in reduced power output and shorten the life of panels.
  • Never use garden rakes or metal shovels to clear snow or debris off solar panels. These tools may cause damage to the panels and lead to premature failure. Only use roof rakes and soft edge clearing tools that are specifically designed for use with solar panels.
