If you’re considering installing a solar system for your home or business, you might be wondering if it will require maintenance. After all, solar panels are designed to last for decades, but will they still perform as well over time? The answer is yes, Solar systems do need some maintenance, but it’s minimal.

What kind of maintenance do solar systems need?

Solar panels are designed to be durable and require very little maintenance. However, a few key tasks should be performed regularly to ensure that your system continues to operate at peak efficiency.

Cleaning: Dirt, dust, and debris can accumulate on solar panels, reducing their efficiency. It’s important to have your panels cleaned at least once a year or more often if you live in a dusty or dirty environment. While it may be possible for you to take this on yourself, professional panel cleaning is not expensive and adds a level of inspection by professionals while they clean.

Monitoring: Solar systems are typically connected to monitoring software that tracks their performance. It’s important to regularly check your monitoring system to ensure that your solar panels are generating the expected amount of electricity. If you notice a drop in performance, it may be time to clean your panels or have them inspected by a professional.

Inspections: Solar systems should be inspected by a professional every 3–5 years or more to ensure that they’re functioning properly. During an inspection, a technician will check the wiring, connections, and other components of your system to make sure that everything is working as it should.

Inverter maintenance: Inverters are an important component of a solar system, as they convert the DC electricity generated by the panels into AC electricity that can be used in your home or business. Inverters typically have a lifespan of 10–15 years and may need to be replaced or serviced during that time.

How often should solar systems be maintained?

The frequency of solar system maintenance depends on several factors, including the environment in which the panels are installed and the type of system you have. Here are some general guidelines:

Cleaning: Solar panels should be cleaned at least once a year, but more often if you live in a dusty or dirty environment.

Monitoring: It’s a good idea to check your solar system’s monitoring software on a regular basis, such as once a month, to ensure that it’s performing as expected.

Inspections: Solar systems should be inspected by a professional every 3–5 years.

Inverter maintenance: Inverters should be inspected and serviced by a professional as needed, typically every 5–10 years.
