Solar energy is one of the most important and prospective renewable energy sources. Solar photovoltaic/thermal systems (PV/T), which could provide both heat and electricity at the same time, are becoming increasingly popular in households and commercial buildings. The PV/T system design parameters and base plate material selection are significant f...

Photovoltaic-thermal road as solar collector is a promising technology. To expand the application of photovoltaic-thermal road, a novel energy system which integrated photovoltaic-thermal road with ground source heat pump system is proposed. Focus on this system, a dynamic mathematical model during non-heating season is established and validated, a...

The photovoltaic-thermal (PVT)-ground source heat pump (GSHP) system has been proved to have great potential in improving building energy efficiency, but ordinary PVT collector requires a large installation area and limits the popularization of PVT. In this paper, a novel solar energy collector, called photovoltaic-thermal road (PVTR), is proposed...

The solar road is a new type of technology for solar energy conversion. As the solar energy utilization efficiency of a solar road is too low, to solve this issue, a novel photovoltaic-thermal road is proposed in this paper. In addition, a mathematical model is developed to evaluate thermal and electrical performance of the photovoltaic-thermal roa...

A solar heating system (SHS) with a phase change material (PCM) thermal storage tank is proposed with the view that traditional heat water storage tanks present several problems including large space requirements, significant heat loss and unstable system performance. An entire heating season (November–March) is selected as the research period on t...

A physical model and dynamic simulation models of a solar phase-change heat storage heating system with a plate solar collector, phase-change material (PCM) storage tank, plate heat exchanger, and auxiliary heat sources were established. A control strategy and numerical models for each of seven different operation modes that cover the entire heatin...
