If you are considering flexible solar panels, it’s good to keep in mind the potential disadvantages when evaluating if they are right for you.
Less Efficient
On average, standard solar panels are 20% to 23% efficient whereas flexible solar panels are only 7% to 15% efficient. To generate the same amount of electricity, that means you would need more flexible solar panels.
Limited Power
Most flexible solar panels on the market only allow for up to 150 watts versus 250 to 300 watts for standard solar panels. For boats, RVs and other smaller applications, 150 watts can be sufficient. However, this may not get the job done when trying to power a home.
Restricted Warranties
Although standard solar panels can come with hefty upfront investments, you can rely on them paying for themselves well before their lifespan comes to an end. That is why most standard solar panel manufacturers offer 20+ years of warranty coverage. Flexible solar panels, however, are not as protected from the elements. They may operate for more than 10 years, but they generally only come with one- to five-year warranties.
