If you’re interested in going solar, you’ve probably heard some things online about the gruelling maintenance process of owning panels, which sounds like a lot of work for an already big investment. Like many things on the internet, this common solar myth is completely untrue and shouldn’t scare you away from installing solar panels.

So what are the facts? Solar panels are actually incredibly easy to maintain, with little to no maintenance necessary for the duration of their lifespan. Even in the unlikely event that something goes wrong, you don’t have to worry about repairing or replacing anything yourself due to the extensive warranties that come with any reputable solar system installation. 

What Type of Maintenance do Solar Panels Actually Need?

Here’s the truth–you probably don’t have to do much maintenance at all. Solar panels are manufactured to be incredibly durable and are made out of tempered glass to withstand whatever mother nature has to throw at them, including hail, strong winds and snow. To get a little more technical, the glass can withstand hail up to 2.5cm–roughly the size of a golf ball falling at a speed of 82.8km an hour. 

You don’t have to worry about cleaning snow off during the winter either, as snow naturally melts off panels quicker than the rest of your roof. We do not encourage any removal of snow or ice on the panels, especially for rooftop systems. Please know that the increase in production for the entire year would be approximately 5%, which is not worth the risk of cleaning snow off your panels.

It’s especially important to note that homeowners should never douse their panels in hot water to melt snow off faster. The extreme difference in temperature can cause tempered glass to crack.

In hotter and dryer climates, it is recommended that homeowners clean their panels at least 2 times a year to get rid of debris, dust and leaves. Using a leaf blower or hose is an easy and effective way to clear any built-up obstructions on your panels to ensure optimal performance over the years. However, in colder climates like Canada, cleaning isn’t necessary at all. Who says it’s not easy to maintain solar panels in the great white north?

How to Check If Your Panels Require Maintenance?

Most modern solar PV systems come with monitoring apps that allow homeowners to track their panels' performance. If you have microinverters installed, it’s even easier to pinpoint an underperforming panel since every panel is working independently. 

If you do notice a problem, contacting your installation company should be a quick fix. They can send someone over to inspect your system and fix any issues at hand. At Polaron, we have an After Service department dedicated to helping customers with any post-installation related questions or concerns, including repairs.

How Warranties Make Maintaining Solar Panels Easy

Warranties exist to protect you financially in the event that your panels break and need to be repaired or replaced. It’s always good to have a security net in place for any significant investment. A range of warranties provides support for varying cases, so it’s best to confirm which warranties come with your system before signing anything with your installer. Good warranties might be more expensive but can save you a lot of money and headaches in the future.

All solar panels are bound to degrade over time. Performance warranties ensure your panels maintain a level of efficiency throughout their lifespan. We use Longi and Canadian solar panels, which both come with 25-year performance warranties. You can still expect your panels to generate 80-90% of their power capacity by the time your warranty expires.

A product warranty ensures proper workmanship and quality of the panels in case of defects or damages. Our panels come with a 10-year product warranty, which is the industry standard for panel product warranties. 

Panels aren’t the only part of a working solar PV system. Inverters are necessary to convert DC into usable AC electricity for your home. Standard warranties for inverters are usually 10 years, but Polaron has personally pre-paid for an extended 20-year warranty on all APSystem inverters that we install with our systems to help make life a little easier for our customers.

Starting your Solar Journey can be as Easy as Maintaining a Solar System

Solar panels are not hard to maintain, especially with today’s warranties and technology in place. The best time to go solar is now, with solar systems offering homeowners a unique solution to help our planet while saving on skyrocketing power bills. After installing your system, there’s not much else for you to do except sit back and relax while reaping all the amazing benefits of going solar.
