ES Solar | Flagship Partner Testimonial

ES Solar has pioneered a novel business model as a PV + battery VPP-focused solar contractor with a 98% battery attachment rate. We sell hundreds of grid-integrated and utility-controlled customer batteries per month focused on creating the energy transition for all of society, as opposed to grid defection for individual homes. 

We work with the sonnen batteries because they are basically bulletproof. Plus sonnen offers us a partnership like no other battery manufacturer. Together we've partnered with the utility to deploy thousands of Wattsmart sonnen batteries in sync with the needs of the grid, improving grid resiliency, and genuinely reducing local CO2 emissions.
