4 FAQs about Distributed solar energy storage ratio

What is the current attachment rate for solar?

Overall attachment rates will remain above 25% for most of this period. In comparison with residential solar, the US non-residential solar segment has been slower to adopt storage, with attachment rates failing to go much above 5% to date.

Which markets have the most non-residential solar-plus-storage capacity?

The markets with the most non-residential solar-plus-storage capacity feature direct storage incentives that encourage developers to pair storage with larger community solar and, or, commercial solar projects. These markets include California, Massachusetts, and New York.

Why are distributed photovoltaic systems important in China?

In recent years, distributed photovoltaic (DPV) systems in China have achieved significant leapfrog development, playing a pivotal role in ensuring reliable power supply, accelerating the green energy transition, and fostering rural income growth and employment opportunities [, ].

What is the difference between residential and non-residential solar-plus-storage?

Like the residential segment, non-residential solar-plus-storage in the US is more concentrated than the market for non-residential solar alone. The top six solar installers captured a market share of just 16% in 2023, whereas the top six solar-plus-storage installers enjoyed more than 50% of the market.
