Batteries to sell While long-standing off-grid and PV backup suppliers have quietly supported solar-plus-storage applications all along, the nation’s largest solar PV installers like Sunrun, SunPower and Tesla started offering battery products to their customers in the last several years. The companies continue to report dramatic growth in the share of battery sales to their traditional PV-only offerings. The advent of well-packaged, long-life lithium-ion batteries has made energy storage more appealing to consumers. When the biggest names in solar get behind batteries, their marketing, messaging and political influence increases awareness among consumers, businesses, and governments alike. Their smaller competitors also take up the cause so that they don’t get left behind. Standardized safety One of the surest signs batteries in homes and businesses are now mainstream is their inclusion in the latest codes and standards. Building and electrical codes published in 2017 and 2018 acknowledged batteries, but rarely went beyond insisting compliance with the then-new UL 9540 safety testing standard. The definitive battery safety standard, National Fire Protection Association (NFPA) 855, was published in late 2019 after a productive engagement between industry representatives and the NFPA – a principal developer of national safety codes. The next round of codes, starting with the 2020 National Electrical Code, has been or will be harmonized with NFPA 855 to provide the same level of guidance to inspectors and building officials that they have for things like HVAC, water heaters and windows. https://www.pv-magazine.com/2020/05/21/three-signs-that-battery-energy-storage-is-mainstream-today/ #Solar #Batteries #Storage #EnergyStorage #SolarPlusStorage #Lithium https://www.instagram.com/p/CA1UzMWHAP3/?igshid=9dlq9hjw8eie
