About Edisun Microgrids

Edisun Microgrids was founded on a vision to create low-cost renewable energy. The idea was incubated by Bill Gross at Idea Labs, his startup factory, before entering into Elemental Excelerator. The concept was simple: utilize concentrated solar power to store energy in natural materials. Specifically, the technology works by using an array of inexpensive, flat mirrors to heat a tank of locally sourced rocks to 500 degrees Celsius. Then utilize a heat engine to create power.

During the Go-to-market Track, Edisun Microgrids was able to run the system in a closed loop for a full 24 hours, generating enough heat during the day to power the facility throughout the evening. In 2016, Edisun became a part of the Elemental Excelerator Demonstration Track.

Edisun has extended its technology to manufacture a rooftop tracker for PV installations. Edisun’s product, PV Booster, boosts the output of PV panels by 30% and the economics of solar installations by 20%.

Project Description

Edisun is working to install their solution on the Big Island of Hawaii. This will be their first commercial size unit of their rock + air CSP technology. The company is working to make this solution a true firm power source that can provide renewable energy around the clock.
