Buying solar can feel intimidating, especially when misleading claims about equipment life keep circulating online.
Offgridmaric (@offgridmaric) is pushing back on one of the most common myths: that a full solar setup only lasts around three years.
Here's what to know
In a TikTok post, the creator wrote, "Yes, some components will eventually need replacing… but your entire setup doesn't suddenly expire after 2–3 years."
@offgridmaric Solar power setups only last 3 years?! We hear this a LOT, so let's clear up one of the common misconceptions about solar. 😅 Yes, some components will eventually need replacing… but your entire setup doesn't suddenly expire after 2–3 years. #solarpower #solarenergy #offgridliving #solarpanels #farmlife ♬ original sound - Music Vibes Chill
Different parts of a solar energy system wear out on different schedules. As a result, maintaining or replacing one component does not mean the whole system has failed.
If homeowners assume a system will "expire" after only a few years, they could miss out on lower utility bills, greater energy independence during outages, and less reliance on unpredictable electricity costs.
One commenter wrote, "In reality, I doubt the '20' on batteries last 8-20 years. Because there are so many factors affecting the lifespan of the batteries."
Battery life and the longevity of other solar equipment can depend heavily on how the system is used and maintained.

More background
Solar systems can seem complicated from the outside. Panels, batteries, wiring, charge controllers, and inverters all serve different functions, so they also come with different maintenance needs and replacement timelines.
Solar is more comparable to other major home systems, where some components need attention sooner than others. Roofs, HVAC systems, and water heaters all work in much the same way, with ongoing upkeep playing a role in long-term ownership.
A well-designed solar setup can lower monthly costs, offer peace of mind during grid outages, and make off-grid or backup-power living more practical. Increased solar adoption can also reduce pollution from fossil-fuel-generated electricity, supporting cleaner air and healthier communities.
What can be done?
Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. It can also make a system more useful day to day by storing excess power for later use instead of letting it go to waste. You can explore EnergySage for information about home battery storage options, including competitive installation estimates.
