How long does a solar inverter last?

When you’re going solar, you want to make sure your investment lasts. Let’s talk about inverter lifespan. Inverters typically last 10-15 years, but with proper care, they can survive for 20 years or more. Of course, how long your inverter lasts depends on several factors.

What is a solar inverter?

The inverter, a device that converts the DC power produced by solar panels into usable AC power, can come in a few different configurations. The two main types of inverters in residential applications are string inverters and microinverters.

What are the different types of solar inverters?

There are three main types: String inverters: These are common and budget-friendly. They connect solar panels in series. However, they may have a shorter lifespan—about 10–15 years. Microinverters: A more advanced option. One microinverter connects to each panel. They typically last longer, up to 25 years.

Are reputable inverters better?

Yes, well-known brands tend to produce more durable and reliable inverters, thanks to their solid reputation. What are the most common causes of inverter failure? Common causes include: manufacturing defects, improper installation, excessive temperature changes, and environmental factors.

How do you maintain a solar inverter?

Keep your inverter cool for a longer life. Moisture: Wet conditions may lead to corrosion. Dry, well-ventilated spots are best. Dust: Dust can hurt magnetic parts. Make sure to clean your inverter often. In short, protect your inverter from harsh conditions. This helps extend its lifespan and keep your solar system running smoothly.

How long do solar panels last?

While solar panels can last 25 to 30 years or more, inverters generally have a shorter life, due to more rapidly aging components. A common source of failure in inverters is wear and weathering on the capacitors in the inverter. The electrolyte capacitors have a shorter lifetime and age faster than dry components, said Solar Harmonics.
