6 FAQs about [Lifespan of rooftop solar 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 solar inverters last?

These may incur damage from weather elements. Solar inverters generally last 10 to 15 years. This shortened lifespan is due to how hard inverters continually work to convert energy from the solar panels into usable electricity for your home. On average, solar inverters cost $1,000 to $2,000 to replace.

Do solar panels expire?

There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.

How efficient is a 10 year old solar panel?

Given the typical degradation rate of about 0.5-0.9% per year, a 10-year-old solar panel can be expected to keep 90-95% of its original efficiency. Starting with an efficiency of 20%, it should still deliver around 18-19% efficiency after a decade.

Do solar panels degrade over time?

While solar panels will inevitably degrade over time, homeowners can take several steps to maximize their lifespan and maintain optimal performance. Maintaining solar panels is key to ensuring a long lifespan. Panels can accumulate dust, dirt, and bird droppings over time, which blocks sunlight and reduces efficiency.

Are solar panels durable?

Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.
