Understanding Solar Panel Degradation: Maintenance Checks for Longevity

Most solar panels are estimated to last between 30-35 years with proper care.

Solar panel longevity helps make your business sustainable while saving on energy costs. If you have the right type of solar panel system, you can effectively eliminate your energy costs for 30 years, potentially saving you tens of thousands on energy bills.

To boost longevity, you need good solar panel maintenance. Wear and tear is a very real problem for solar panels, as they sit exposed to the elements.

In today's post, we'll teach you about maintenance checks for solar panel longevity. Keep reading and give your solar panels a full lifespan.

Common Solar Panel Problems

There are several common solar panel problems to keep an eye out for. Being exposed to weather of all kinds results in a lot of wear and tear on the panels. You need to inspect for dirt and debris regularly so that it doesn't build up and cause serious problems.

Another common issue is fluctuating temperatures that cause cracks in the panels. As temperatures rise and drop, the solar panel materials expand and contract slightly. Without the proper components - expansion joints - micro-cracks can form on the panels.

These micro-cracks can lead to what is known as "snail trails". They occur when the CO² in the air mixes with silver acetate on the panels. The result is a discoloration that looks bad and hurts the system's efficiency.

Solar Panel Cleaning

One important aspect of solar panel maintenance is regular cleaning. You can use pressurized water to clean your solar panels. As long as they're at the right angle, you should be able to see and rid the panels of dirt and debris.

To scrub more hard-to-remove debris, use a homemade cleaning solution and a soft brush or sponge that won't scratch the panel surface. Depending on the placement and orientation of your panels, cleaning can be dangerous. It's best to hire a professional to get up on your roof and handle these cleaning duties.

Keep Track of Power Generation

To get a sense of how your solar panels are performing overall, record the power generation over a few months. Do it at the same time of day, every day, until you've got enough data to see how your system is performing in a variety of conditions.

If the panels aren't performing as they should, you may need an inspection and repairs. Things like microcracks or issues with your inverter are hard to detect unless you know what to look for.

Inspect Components for Damage

You can get up close to the panels and inspect them for damage yourself. First, check the panels for micro-cracks and discoloration. You should also look for corrosion and clean it with a solution of baking soda and water with a soft brush.

Inspect your wiring for sulfation and corrosion as well. If wiring issues go undetected, they can seriously damage your system over time. Don't touch the wiring if you're not experienced with it, as it can be dangerous for you and your solar panels.
