Residential 16kW + Battery Storage
I love the system. LightWave did a precision installation job.
-Greg Grant, Grant Residence
In 2015 LightWave Solar installed an 11kW grid-tied solar system for Greg Grant at his home in Brentwood, TN. At the time, Greg was interested in batteries, but we recommended he wait until storage technology improved. In Spring 2018, we added a new 5kW solar system with battery storage. The new system will further reduce his monthly electrical use as well as provide backup power during grid outages.
“My initial system has been so good and efficient that I wanted to make it even better,” says Grant. “I wanted to do it while the tax incentives are still available,” he says.
Greg’s new system includes 16 SunPower solar panels, a StorEdge inverter and two LG Chem lithium-ion batteries. During a grid outage, the system will provide 18.6 kilowatt-hours of stored electricity which will be enough to power his refrigerator, internet, security system, outside lights, 2 outlets in his kitchen, and 3 outlets and a ceiling fan in his bedroom.
“I was a boy scout, so I’ve always tried to be as prepared as possible,” says Grant.
Inside Greg’s garage you can see two inverters on the right which are part of his original grid-tied solar system. On the left he has two LG Chem lithium-ion batteries with a StorEdge inverter in the middle. On a daily basis, Greg’s new system reduces his electric use, which has increased recently since he’s been charging his Prius Plug-in Hybrid car.
