The new solution, which will automatically reduce demand on the electric utility grid, is currently available in California, Hawaii and New York.

It offers guarantees for significant energy savings against current and possible future tariffs.

The solution utilizes Kyocera’s high-performance solar modules to maximize savings and the company’s experience will help the system expand beyond its existing markets.

Stem’s behind-the-meter energy storage and predictive analytics combine in the system to allow rapid response to spikes in commercial customers’ electricity demand.

The company’s system can save customers about 20% on their annual electricity bill and can also predict power usage up to 30 days in advance.

Stem CEO John Carrington said: "Intelligent energy storage is a natural fit for PV — and our solution integrates seamlessly with Kyocera’s solar technology to bring new value to the commercial market.

"Kyocera’s expertise in providing turnkey solutions through its technology partners presents a great opportunity for Stem as we expand our offering to solar customers."

Kyocera Solar president Steve Hill said: "Kyocera is an industry leader in solar module reliability, and the Stem platform will optimize our customers’ energy use through real-time data and state-of-the-art energy storage technology.

"Simply put, we believe our comprehensive solution offers a greater return, in a shorter period, and with a longer total lifespan, than any competing renewable energy system."
