Solar Panel Maintenance : Everything You Need to Know

So, you’ve installed your solar panels, which are now producing clean, low-cost energy for your home. How do you maintain your solar panels to ensure they keep producing at maximum efficiency?

This is a common question amongst homeowners. Protecting and caring for your investment is essential to owning any item. Thankfully, solar panels are incredibly durable. Most panels are made of tempered glass, anodized aluminum, and (aside from tracking arrays) have no moving parts.

How to clean your solar panels

For debris from trees, birds, and general dust build-up, some low-cost solutions are:

• A leaf blower
• A simple, quick rinse with a hose of water
• Or even light rain can wash away panel build-up (rain usually won’t clean off flat panels)

For removing a heavy layer of snow:

• Throw a soft football to shake the snow loose (this could end up in a lost football)
• Use a leaf blower
• Use a long pole with a squeegee at the end
• Spray your panels with lukewarm water

If it is a light layer of snow, it will likely slide off, cleaning your panels in the process (this isn’t applicable for flat panels)

When cleaning your panels, NEVER:

• Spray hot water on cold panels
• Use RainX
• Use car wax
• Rock salt

These options can permanently damage your panels, roof, and electrical elements, causing more harm than good.

Solar Panel Monitoring

A solar panel monitoring system is the best way to ensure your project performs at its best. Monitoring systems provide data on the electrical output of your solar system. You can track this data over time to calculate the degradation of your panels. Monitoring systems also provide a notification if there is a malfunction or damage.

**Safety is of utmost importance for all matters concerning your solar system. You can almost always maintain and clean your panels from the ground with a hose. However, if you need to get to your panels, use caution when climbing on your roof.

Extreme care should be taken if surfaces are slippery or wet. Do not touch the electrical components of your system at any time. Also, please make sure you properly secure your ladder before attempting to get up on your roof**

Solar systems are incredibly durable and last for many years. To date, the first generation of solar panels, made with less advanced technology, are still performing exceptionally well!
