The declining cost of silicon PV [12] and increasing energy prices drive the application of energy storage to capture solar energy for later use within the building. In the UK, the early rooftop PV deployment was generally driven by government subsidised feed-in tariffs (FIT) [13], which gave a subsidy for electricity generated regardless of
