Some of the more popular solar installation solution providers have made the solar + storage sales process even easier for their dealers and authorized installers to perfect. In addition to providing solar panels and packaged mounting and inverters, companies like SunPower, LG and Panasonic have now brought branded energy storage systems into their residential offerings. The goal is one-company-backed warranties for systems, rather than making installers piece together multiple branded products with differing coverage lengths.
This is all perfect timing considering residential storage’s expected incline, especially as California residents grapple with utility shutoffs during extreme weather. The United States installed a record-breaking 35 MW of residential storage in Q2 2019, beating the last record-setting quarter (Q2 2018) by 9 MW. With more customers requesting solar and storage based on brand awareness, SunPower, LG and Panasonic were smart to bring exclusive batteries into their portfolios.
“We’re entering a new solar decade as storage adoption increases with the advancement of battery technologies, and with accompanying services becoming standard,” said Norm Taffe, SunPower executive VP of residential solar, in a press release.
LG first released two battery options (an AC-coupled 5-kW system and a DC-coupled 7.6-kW system) to its loyal installers in 2018. SunPower and Panasonic both made storage product announcements at Solar Power International 2019. SunPower’s lithium-iron phosphate Equinox Storage product provides up to 12 kWh of storage capacity. Panasonic (which had previously partnered with Pika Energy for storage) released its EverVolt system, also available in AC- and DC-coupled versions that can be expanded up to 34.2 kWh.
“Energy storage is one of the fastest-growing segments in the renewable energy space, and homeowners are eager to find a product that fits their exact needs,” said Mukesh Sethi, group manager at Panasonic Solar, in a press release.
