Solar batteries: Attractive retrofitting of PV systems with energy storage Enerkeep finds out

The best rate of return offer with solar batteries retrofitted PV systems, that have been installed between 2009 and 2012. That’s the conclusion of profitability calculations of Enerkeep. “The yield of retrofitting of installations can even outnumber subsidized new PV installation with solar batteries”, Kai Wu, CEO of Enerkeep said.

AC-systems easier to install

He recommends AC-systems for retrofitting because they are usually faster and easier to install, since they can be integrated in existing AC grid. Furthermore, they match better to the subsidy system for self-consumption of KfW in Germany. Enerkeep also offers an online tool. (HCN)
