Panasonic solar panels: the complete review

As one of the world’s largest consumer electronics manufacturers, Panasonic is a household name that entered the solar industry in 1975. Panasonic solar panels are popular among EnergySage shoppers and installers – in fact, they’re the third most quoted brand in 2023! However, in 2021 Panasonic announced that they’ll no longer manufacture their own solar panels (they previously had a manufacturing deal with Tesla). But if you’re interested in Panasonic solar panels, don’t worry: unlike LG Solar, Panasonic is continuing to sell high-performing panels – manufacturing is now just outsourced to a third party. 

When evaluating your solar panel options, it’s important to compare what’s available so you can be confident in your solar investment. Let’s take a look at Panasonic’s solar panel technology and how it compares to other leading solar panel brands available today.

how long do solar panels last

How long do solar panels last? Solar panel lifespan explained

The industry standard for the lifespan of solar panels is 25-30 years. However, a solar panel won’t die after 25-30 years – rather, its power output will decrease a significant amount below what the manufacturer projected. It’s hard to understand the upfront cost of going solar without knowing how long you can expect your rooftop panels to produce ample energy. Ultimately, your solar panels will offset your electricity use for decades and significantly reduce your energy bills – but to get a sense of when you’ll need to replace your system, it’s important to understand industry projections and degradation rates.
