MIAMI-DADE COUNTY, Fla. – Solar energy made headlines in the weeks following Hurricane Ian after one Florida community that is 100 percent solar-powered never lost power during the storm.
But despite the benefits that technology can provide, some users feel that there are still too many obstacles.
In 2017 Cindy Lewis lost her home in Layton in the Florida Keys after Hurricane Irma.
“I had between two and a half to three feet of seawater in my house,” Lewis told Local 10’s Amy Viteri. “So everything, everything I had in the house was destroyed.”
Lewis rebuilt a new, more storm-proof house on the same lot. The new structure sits on stilts well above sea level. But among the many steps that Lewis took to strengthen her home, one of the biggest investments she made was the installation of solar panels on her roof.
“Well, let’s put it this way, I haven’t had a power bill in two and a half years,” Lewis explained. “I’ve produced enough energy here in my 15 solar panels on this little roof to fully power the house every month, and I sell it back to the grid.”
She said that she is now looking to buy battery storage for her system, which will allow the panels to continue providing energy even in the event of a blackout.
“That will absolutely give me peace of mind. I have friends who have battery backups, and on occasions where there is an outage, the transition is smooth,” she added.
In September, after Hurricane Ian, a planned 100 percent solar-powered community made headlines when it never lost power during the storm. The town of Babcock Ranch sits about 15 miles from hard-hit Fort Myers. Its field of 700 thousand solar panels, managed by Florida Power andamp; Light were seen untouched. When asked about the community, an FPL spokesperson told Local 10 News while the panels held up well in the storm, their storm-hardened grid played a role.
“The vast majority of our lines at Babcock Ranch are also underground, which, according to data, performed five times better in Southwest Florida than above-ground lines during Ian, ” said the speaker.
“I think Ian is giving us an opportunity to think about like, how do we want to make our communities more resilient? Looking at solar and solar storage together is a really good option,” said Laura Tellez, the program coordinator for the South Florida nonprofit United Solar Neighborhoods. “So it’s important to understand that unless you have battery storage, if the power goes out, even if you have solar, your system will automatically shut down. That is to protect every utility worker.”
But in the Sunshine state, many solar users feel the technology has faced too many obstacles.
This year the Florida legislature passed a controversial bill, supported by FPL that would have largely done away with what is known as net metering, the process by which energy users solar panels lower their bills by getting a credit for the extra energy they produce.
Ultimately Governor Ron DeSantis came to veto the bill, citing inflation and rising costs, saying: “The state of Florida should not contribute to the financial crisis that our citizens are experiencing.”
FPL also raised rates and imposed a minimum base bill that went into effect this summer. The move has awakened many customers who are now forced to pay the twenty-five dollar minimum whether they use that power or not.
Solar users like Jim Blankenship felt particularly targeted by the policy.
“This forces me to buy energy that I do not have access to, as a solar customer. And that’s not true for non-solar customers,” he said.
Blankenship, who lives in Vero Beach argued that the energy he is paying for and not using, because he is generating his own energy, would be enough to run an electric car for a whole year.
“I believe we were being penalized. And the solar business is being penalized,” he said.
Lewis, who lives in the Keys and is not an FPL customer, is therefore not subject to the minimum bill. She said her 15 panels generate enough energy for her to charge her electric car and still have a zero energy bill every month.
“Remove these barriers so people can at least make that choice,” Lewis said, “Make it an affordable choice for everyone, or more affordable for more people.”
In response to criticism of the minimum bill, FPL Spokesman Chris McGrath told Local 10 News in an email: “The base minimum bill helps ensure that other customers are not subsidizing customers with low or zero. The minimum base bill is an alternative to the base charge increase, which affects everyone. The vast majority of our customers will have electricity usage that exceeds the low threshold for a minimal minimum bill.”
The federal government recently renewed a tax incentive that allows a 30% credit on any solar system installed, including back-up battery storage over the next ten years.

Not only are solar panels remarkably reliable, the longevity of solar panels has increased dramatically over the past 20 years.
How often do rooftop solar panels need to be replaced? The solar panels last about 25-30 years, which is similar to the life of a roof. By doing both at the same time, you avoid having your solar panels reinstalled after you replace your roof, which can save you money in the long run.
What happens to a solar panel after 25 years?
Most solar panel companies will provide a standard warranty of 25 years for the expected lifespan of the solar panels. After 25 years, your solar panels do not necessarily need to be replaced; however, their ability to absorb sunlight will be reduced.
Do solar panels deteriorate with age?
The efficiency of solar panels is higher than ever, but the amount of electricity the panels can generate still gradually decreases over time. High quality solar panels degrade at a rate of about 0.5% each year, and generate about 12-15% less energy at the end of their 25-30 life.
What happens to a solar panel after 30 years?

What do you do with solar panels after 25 years?
But in reality, studies have shown that panels continue to operate with greatly reduced efficiency after the warranty expires. Let’s do some math: solar panels suffer from a loss of efficiency of 0.5% to 1% every year. At the end of a 25-year warranty, your panels should still produce energy with 75-87.5% of their nominal output.
