As the end of summer draws near, many maintenance managers are performing tasks that will prepare their buildings for the colder months. Solar power is expected to generate 10 per cent of our global power by the year 2030, so more and more maintenance managers will need to learn about their functionality and upkeep. If you have solar panels on your property, have you been performing regular maintenance?

While it’s true that solar panels are not typically high maintenance, there are a few steps you can take to maximize their optimal performance.

Keep them clean

The rain often cleans the panels through the summer, but dust, dirt, and debris can still accumulate. MIT research reveals that dirty solar panels can be up to 30 per cent less efficient, so keeping them clean is a priority.  If you can walk safely between the panels, the best way to clean them is with a soft sponge or squeegee and a bucket of soapy water. Letting panels air-dry is recommended.

Companies located in low-water areas may be challenged to clean the panels regularly, but new technology is being developed using electrostatic repulsion to clean the panels without using water or brushes that could scratch the surface.

Your panels in the winter

Solar panels produce energy year-round, but you may need to periodically visit the roof to remove accumulated snow to maximize their exposure to sunlight and keep them at optimal performance. Some installers recommend incorporating features like snow guards to protect the panels from accumulating ice and snow, limiting their maintenance needs.

Tilting and positioning your panels can also help you access the most sunlight through the winter months.  By monitoring your energy capture, you can make necessary adjustments to maximize your energy gain through the winter.

Solar panels are designed to last up to 30 years, so with a little year-round maintenance, your panels will perform at their best and experience a long lifespan.
