Petaluma’s Enphase Energy strives to survive as solar industry transforms
New opportunities are expected to shine soon on the world’s solar industry, and Petaluma’s Enphase Energy is striving to survive long enough to enjoy them.
The energy tech company with 350 employees has reported annual losses every year since it went public in 2012, including nearly $67.5 million worth of red ink last year. Since September, it has gone through two rounds of layoffs and raised about $26 million by issuing new stock and bringing in two major investors.
Enphase officials say with confidence that a turnaround is underway and the company is on track to make a profit in the second half of 2017. Its employees have worked to significantly cut the cost of producing its signature devices, microinverters that take DC, or direct current, power from solar panels and transform it into AC, or alternating current, power for homes.
And one of its recent products, an encased home battery system, is making its U.S. debut just as the rules governing solar energy rates are changing in California, home to half the nation’s solar production.
Due to the rate change, new rooftop solar owners are expected to make less money than their predecessors for the power they sell to utilities in the Golden State. As such, energy storage systems and rate-savvy monitoring technology could one day help future solar owners take advantage of the best times to buy, sell and store power.
“The way people are approaching the solar business today will look antiquated in just a couple of years from now,” said Enphase President and CEO Paul Nahi.
Residents won’t simply buy solar panels, but complete energy packages that include storage and operating systems managed in the cloud, he said. And Enphase has the products and software technology to maximize efficiency.
How soon this shift happens in California remains to be seen. The experience in Hawaii, which has the largest concentration of solar energy systems per capita, suggests that a change in solar rates can bring a period where solar energy systems make less financial sense, even when adding storage.
Indeed, earlier this month the head of the California Solar Energy Industries association told the Los Angeles Times that 2017 will be the first year since 2008 with a zero growth rate for solar installations in the state. The reason is that with the change in rates and the end of a state solar subsidy, many consumers question how they’re going to save enough money by installing a rooftop system.
Even so, major battery makers such as Tesla and German-based Sonnen see great opportunity in supplying energy storage to American homes, businesses and communities.
For rooftop solar owners, storage one day could prove a better option than simply selling daytime electricity to the grid for next to nothing and buying power back in the evening at peak prices, said Blake Richetta, Sonnen’s vice president of sales for the Americas. Moreover, storage is a better solution to meet evening energy demands than building and operating more carbon-emitting natural gas plants to be used for just a few hours each day.
“This is why storage is the future,” said Richetta. It fits with the reality that solar systems provide power in the daylight when most residents aren’t home, but not in the evening when demand spikes.
In the past seven years, Sonnen has installed 16,000 residential battery systems, mostly in Germany. For communities to build the most sustainable energy systems, he said, “you want to store sunlight.”
Enphase began in 2006 and touts itself as the inventor of the microinverter, a paperback-sized device that installers typically attach beneath each rooftop solar panel. The alternate approach is to install a single large inverter that converts the DC power from all the system’s solar panels.
After the company went public in March 2012, Enphase stock ended its first day of trading at $7.34 per share. It peaked at $16.79 in September 2014 and ended Friday at $1.24.
Enphase received ?$322.6 million in revenues last year and reported an annual loss of $1.34 per share.
In the past two years, the company’s losses were partly due to a decrease in market share and a drop in the price paid for microinverters. To address that, Enphase worked to cut the production costs, and by dropping prices the company was able to increase its U.S. market share to 30 percent by Dec. 31 from 20 percent in the year’s first quarter.
In the company’s Feb. 28 earnings conference call, Enphase CFO Bert Garcia told analysts and investors, “We acknowledge there is substantial doubt about our ability to continue as a going concern.”
But company officials made their case for why they expect to be profitable in the second half of this year. Key among the reasons is their work to cut the cost of producing microinverters at a time of fierce competition among solar component makers.
