Local solar installation companies have faced a number of challenges in recent years, from the decline of state net metering policies to the Trump administration’s import tariffs. Now, a potentially significant opportunity is coming into focus for them: home battery systems. 2019 was a big year for both residential solar and home storage in the U.S. Power shutoffs in California and demand pull-in from the Investment Tax Credit helped both industries log new records. Yet while much of the attention on solar-plus-storage has focused on leading national installers — SunPower unveiled its in-house residential storage product in September — conversations with local solar installers across the country show that, heading into 2020, interest in storage is trickling into many more sales conversations. It’s a trend that underscores the growing interconnect between the two sectors. Rooftop solar remains a vastly larger market than home storage systems. U.S. homes added about 1.9 gigawatts of solar capacity through the first three quarters of 2019, compared to just 98.3 megawatts of storage.
