Installations of home energy storage system in the U.S. hit a record high in the first quarter of 2018, according to a new industry report. The new capacity of 36 megawatt-hours will sustain an estimated 4,000 home systems and adds to the 1,080 megawatt-hours installed in the past 4 years.
The big picture: Home energy storage systems commonly use batteries to store the electricity generated by rooftop solar panels, which can then be used during peak times and on demand to reduce utility costs or for backup power during inclement weather. The increasing penetration of residential and commercial solar installations has lowered energy demands on utilities. But the policies they have implemented to offset those losses have ended up making home energy systems even more attractive.
