sonnen accelerates US market efforts with solar-plus-storage technology package

sonnen, the European market leader for smart energy storage systems, announced a partnership with SolarWorld, the largest crystalline-silicon solar manufacturer in the US and PetersenDean, the nation’s largest residential roofing company with more than a million roofs under its belt. The new solar-plus-storage package offers US homeowners a straightforward path for using renewable energy.


Additionally, sonnen is working with Spruce, an expert in residential solar and efficiency financing, to develop new financing for energy storage.

The all-in-one storage-plus-solar system uses the sonnenBatterie eco storage system to provide benefits to residential customers, from cost savings through better energy management, to backup power in the event of grid outages and the capability to go off-grid.

The modular sonnenBatterie eco unit delivers continuous output of 3,000 W – 8,000 W, with usable capacity of 4 kWh - 16 kWh (in 2 kWh steps). Guaranteed lifetime is 10,000 cycles or 10 years.

Spruce, an expert in residential solar and efficiency financing, and sonnen are developing financing purely focused on residential electricity storage, and plan to make it available to sonnen's channel partners in the first quarter of 2016.

Additionally, sonnen announced the opening of a new office in Los Angeles, increasing its physical presence in the US. Since its entry into the US market, sonnen has established a research and development facility in Georgia and product manufacturing in California.

sonnen was founded in Germany and started delivering the first generation of its smart storage system sonnenBatterie in 2011. Since then, the company has installed about 10,000 storage solutions throughout Europe.

sonnen has already partnered with more than 30 local solar installation companies in the US that have the expertise, outstanding customer service, and credibility in their territories and is expanding this partner base in 2016 throughout the US.



This could be one way to replace power grid and CPPs usage in USA with clean pollution less energy.

A few million of these and home grid e-consumption could become negative, specially in sunny Southern USA and many areas in China and India.


Continuous for ?hours. Cost?
