Few places in the country are so warm and bright as Mary Wilkerson’s property on the beach near St. Petersburg, Fla., a city once noted in the Guinness Book of World Records for a 768-day stretch of sunny days.
But while Florida advertises itself as the Sunshine State, power company executives and regulators have worked successfully to keep most Floridians from using that sunshine to generate their own power.
Wilkerson discovered the paradox when she set out to harness sunlight into electricity for the vintage cottages she rents out at Indian Rocks Beach. She would have had an easier time installing solar panels, she found, if she had put the homes on a flatbed and transported them to chilly Massachusetts.
“My husband and I are looking at each other and saying, ‘This is absurd,’” said Wilkerson, whose property is so sunny that a European guest under doctor’s orders to treat sunlight deprivation returns every year. The guest, who has solar panels on his home in Germany, is bewildered by their scarcity in a place with such abundant light.
Florida is one of several states, mostly in the Southeast, that combine copious sunshine with extensive rules designed to block its use by homeowners to generate power.
States like Massachusetts, New Jersey and New York — not known for clear, blue skies — have outpaced their counterparts to the south in the installation of rooftop solar panels.
While the precise rules vary from state to state, one explanation is the same: opposition from utilities grown nervous by the rapid encroachment of solar firms on their business.
The business models that have made solar systems financially viable for millions of homeowners in California, New England and elsewhere around the country are largely illegal in Florida, Virginia, South Carolina and some other Southern states. Companies that pioneered the industry, such as SolarCity Corp. and Sunrun Inc., do not even attempt to do business there.
“We get all kinds of inquiries every day” from the South, said Will Craven, spokesman for SolarCity. “People there want to be our customers.”
Florida, in particular, is known as the “sleeping giant” of his industry, Craven said. “It has a ton of sunshine, a ton of rooftops,” he said. “But there is no rooftop solar industry in Florida.”
In South Carolina and Virginia combined, only a few hundred homes have solar panels, according to the Solar Energy Industries Assn. New Jersey has 21,500; California, 234,600.
Under the typical business model for the solar industry, homeowners sign lease agreements with installation companies. The homeowners pay the cost of the panels over time and sell any excess power the systems generate.
Along with tax breaks and other government incentives, the lease agreements have made solar installations increasingly affordable.
States where solar thrives typically pay homeowners attractive rates for the excess power they generate and require utilities to get a considerable share of their power from renewable sources. That gives companies an incentive to promote use of solar.
Southern states, several of which cherish low electricity rates afforded by extensive use of coal, typically have far fewer solar incentives.
Several also have rules that specifically discourage homeowners from going solar. In addition to the bans and restrictions on leasing arrangements, some Southern states assess taxes and fees on solar equipment and generation that do not exist elsewhere.
When Washington and Lee University in Lexington, Va., installed solar panels a few years ago, for example, the local utility, Dominion Virginia Power, threatened legal action. The utility said that only it could sell electricity in its service area. The university and the solar firm it worked with had to change their lease arrangement and forfeit valuable tax credits.
Soon after, in South Carolina, objections from another utility forced the cancellation of about 80 contracts under which a solar firm had planned to provide panels free of charge to churches and school districts.
The resulting backlash forced a change in the state’s law, but a limited one. South Carolina Gov. Nikki Haley last week signed a bill that directed regulators to establish rules under which leasing would be permitted.
The details still need to be worked out, however, and solar firms worry the rules will be heavily influenced by electric companies that will insist on provisions to discourage installations.
For now, many homeowners and businesses that want to install panels are in the same predicament as Wilkerson. Finding no viable option to lease a system in Florida, she is exploring paying cash to buy one outright for three of the cottages she owns. The cost: $106,000.
Utility officials say the policies inhibiting solar installations result from more than a mere turf battle. Utilities bear the cost of maintaining the power lines, switches and extensive computer networks that make up the electrical grid.
How much of a burden homeowners who install rooftop solar systems place on the grid is hotly debated between utilities and environmentalists.
“We want to bring on more renewables, but we also want to make sure the cost of electricity stays reasonable,” said Randy Wheeless, a spokesman for Duke Energy Corp., which serves customers in the Carolinas, the Midwest and Florida.
Officials at Dominion Virginia Power say they are moving as aggressively as they can to promote solar in a heavily regulated, fiscally conservative state reluctant to subsidize homeowners who go green.
Nearly two years ago, the company launched a pilot program that mimics the SolarCity and Sunrun models for leasing solar equipment to businesses. So far, two systems have been installed.
“It might sound small,” said Dianne Corsello, manager of customer solutions at Dominion, but she says regulators want to see evidence that such programs will not create unreasonable costs for the utility.
“We are studying the impacts and assessing the benefits to our grid,” she said. “It is providing an opportunity to get data.”
Solar installation firms scoff at such utility programs. Sunrun Vice President Bryan Miller calls the Dominion rooftop effort “a make-believe program” designed for public relations, not to entice customers to install panels.
Back in South Carolina, solar advocates were pleased last week to see the governor sign the new law loosening restrictions on the industry, but were are also growing impatient.
“There is so much pent-up demand,” said Blan Holman, managing attorney at the Charleston office of the Southern Environmental Law Center. “The sunshine is so obviously abundant. It is 98 degrees here today.”
