"abstract": "<p>Several heat storage systems for domestic application can be used to promote Renewable Energy Sources (RES) penetration by storing excess energy, which would otherwise be rejected during curtailments. The present study investigates two types of PV powered latent heat storage technologies for delivering heat and/or electricity at residential buildings and compares them against a reference case which uses a conventional heat pump as a heating system, also powered by a PV. One technology involves a low temperature PCM thermal energy storage system (LT-TES) heated by either an electric resistance or a heat pump and the other technology involves an ultra-high temperature TES (UHT-TES). It is revealed that any case with heat storage is preferable for better exploiting the produced renewable energy than the conventional one which does not include heat storage. The most favorable from this aspect are the cases which include the UHT-TES, which provide both heat and electricity. Focusing exclusively on heat supply, the most preferable case from a technical performance aspect is the one which includes a heat pump and a LT-TES system, albeit not providing any electricity. On the other hand, the most advantageous only in terms of electricity supply is the case which includes the UHT-TES system.</p>",
