What is the Lifetime of a Solar Power System?

Solar power systems such as solar panels, capture the sun’s energy and convert it into electricity that you can use in your home. Not only can these installations reduce your utility bills, but they’re great for the environment too. If you’re considering having solar panels added to your home or business then you’re probably wondering about the lifespan of the system and whether it’s a worthwhile investment.

How long do solar panels last?

The majority of solar panels are said to last 25 years. However, not all installations are the same. If you want to get the most out of your product, always consider the quality of the panels – high-quality solar panels will usually stand the test of time and even last beyond the standard 25 years. That’s 25 years of saving energy and doing your part for the planet, all while reducing your bills too.

What affects the longevity of solar panels?

One of the main benefits of solar panels is that they are very low maintenance since they only rely on the sun’s rays to work. That being said, if you purchase low-quality panels you won’t have the same experience as you would have a good quality solar system. This is because the lifecycle of the panels is often reflected in the price, as cheaper sealants, framing and cells can deteriorate a lot quicker. Solar panels can only perform to the level of the lowest working panel, so it only takes one failure to affect the entire system.

You should also consider the cables and mounting systems used. Although they are less influential to the overall lifespan, non-branded and cheaper alternatives can lead to system failures early on. If you want a system that will last, consider the system in its entirety and how it will work effectively as one.

How do solar systems change over time?

LG solar panels usually decrease in power around 0.3-0.35% per year after the first year, but lower quality panels start at a lower wattage to begin with, degrading to around 230-252 watts per panel after 25 years – if they are still working! As solar panels are external fixtures they are exposed to all kinds of weather conditions, not just the sun. Generally speaking, cheaper installations deteriorate much quicker, often double or even triple the rate of top quality solar panels.
