Aside from the obvious benefit of improved round-trip efficiency, DC-coupled energy storage uniquely delivers additional value streams not captured on the infamous Rocky Mountain Institute wheel of values. These include: DC clipping recapture, low energy harvesting and maximizing solar deployment potential. This session will explore those additional values in details and how increasing the DC ratio of a solar installation to 2+ can reduce the solar systems installation cost by as much as 20%. This has the added benefit of reducing the AC rating of the solar installation by 40%+ which can result in more solar being deployed based on utility interconnection limits.
