Low residential solar feed-in tariffs can encourage battery deployment
Analysis of feed-in tariff scenarios in Central and Eastern Europe finds that while high feed-in tariffs are linked to the adoption of residential solar, lower tariffs are more likely to encourage battery installations. The study proposes a moderately low range of tariffs as one compromise to support both technologies.
