There’s no arguing that purchasing a high-quality solar panel in San Diego is a sound investment – an investment in the future of your home. After all, living in San Diego comes with a variety of perks and the main one is that it’s always sunny. You can bask in the sun on its beautiful Mission Beach or take advantage of all that sunlight by going solar! If you’ve already decided to do so, you’re probably curious how long you can expect a solar panel to last. Here’s what you need to know.

So, how long is the life of a solar panel?

On average, solar panels manufactured nowadays are made of durable, high-quality materials that guarantee their long lifespan. More importantly, solar panels come with an actual 20 to 25-year warranty. The warranty period guarantees not only that the solar panel will remain in good condition for a minimum of two decades, but also that it will remain efficient.

Nothing illustrates how far science and technology have gone like looking at facts and numbers, both of which are impressive. According to their warranty, solar panels are guaranteed to produce a minimum of 80% of their rated power even after being used for 20 years. But there is more good news.

When does the panel start to deteriorate?

There is a general rule of thumb according to which the panel starts to degrade by approximately 1% every year that it is used. However, the National Renewable Energy Laboratory reached a different conclusion: they claim that the rule does not even apply to panels made before the year 2000.

Because science and technology have advanced so much in the past 20 years, it is certainly not true for the latest solar panel solutions. According to the research, modern solar panels are guaranteed to be up and running long after their warranty period expires and degrade at a rate of 0.4% a year. Even their much older counterparts seem to remain in excellent shape for a long time, degrading at a slightly higher annual rate of 0.5%.

In order to establish whether the panel can produce sufficient power for your household, it has to be the correct size for your home and its rooftop. In other words, the panel or panels have to cover a big enough surface. That said, the level of maintenance will naturally depend on the surface area that has to undergo maintenance.
