20 years ago the problem with rooftop solar was that customers needed a large collection of lead acid batteries to store their daytime energy and use this energy at night. But simple net metering rules made it possible for the electric grid to function as a 100% efficient storage device. Unfortunately, utilities are doing everything they can to eliminate net metering so they can maximize their profits. So the compelling need for battery storage linked with rooftop solar has re-emerged.
Although lead acid batteries are an inexpensive and mature technology, they are not well suited for home energy storage applications. Fortunately, lithium ion batteries have become much more reliable and inexpensive – primarily because of production volumes required by the automotive industry. And just in the nick of time as net metering is constrained in some states, and time-of-use electric rates shift towards late afternoons and evenings (limiting potential rooftop solar savings).
LG Chemical is one of the largest battery manufacturers in the world. They recently introduced a line of residential and commercial energy storage systems that are optimized for both residential and commercial solar applications. LG knows how to make reliable appliances – which is essentially what a home battery storage system will be in the home of the future.
My guest on this week’s Energy Show is Linh Tran, Western Regional Sales Manager for LG Chem Power. In addition to explaining the features and benefits of LG Chem’s battery storage products, Linh also explains the special handling requirements that are mandatory for installers of large battery storage systems (hint: DOT Hazmat training is required). For a quick education on the latest in home battery storage, Please Listen Up to this week’s Energy Show on Renewable Energy World.
