How long is the normal maintenance life of photovoltaic panels

How long do solar panels last?

Surprisingly, solar panel lifespan has always been extremely good. Given they have no moving parts, there is rarely something that can go wrong within the solar panel itself, which means they can keep generating electricity for a very long time. However, what has improved is the level a solar panel will be performing at after 25 years of usage.

How long do monocrystalline solar panels last?

However, when it comes to longevity, monocrystalline panels have the upper hand. While both types of panels typically come with a 25-year warranty, monocrystalline panels have a longer lifespan. According to the American Solar Energy Society, monocrystalline solar panels last around 40 years, whilst polycrystalline models last roughly 35 years.

How often do solar panels degrade?

The average degradation rate for solar panels is about 0.5% per year. This means that after 20 years, a panel should still be operating at about 90% of its original efficiency. However, this rate can increase slightly over time, particularly in hot climates. What Factors Influence Solar Panel Degradation?

How often should solar panels be serviced?

Homeowners should have their panels inspected and serviced every 3 to 5 years. Service technicians not only work on the panels but also check wiring, inverters, major connection points, and battery banks if present. Investing in high-quality solar panels and equipment can significantly impact the system’s longevity.

Why should you service your solar panels regularly?

Having your solar panels regularly serviced by a reputable professional allows you to discover potential problems early. By doing so, you can take the appropriate measures to fix issues and prevent problems that could cause greater damage to your panels over time.

What is a solar performance warranty?

The performance warranty guarantees that the solar panels will produce a certain percentage of their rated power output over time, usually promising around 80-90% of their original output by the end of the warranty period. These warranties protect your solar investment by making sure the panels work as they should for a long time.
