This work deals with the performance evaluation of novel flat photovoltaic–thermal (PV–T) modules under vacuum. Through a 1D (dimensional) steady-state-energy-balance numerical model developed in MATLAB, two different layouts are studied: first consisting photovoltaic (PV) cell installed just below glass encapsulating panel, and second where PV is placed on selective solar absorber (SSA). In bo...

This paper introduces the functioning principle as well as dimensioning elements of a new active solar heating system using air as heat carrier. The air is heated in flat-plate collectors and then circulated through the building walls having circulation “hollows”. The heat storage function is performed by a rockbed storage unit. The solar collectors have water-air double service and supply the ...

Energy consumption is steadily increasing with the ever-growing population, leading to a rise in global warming. Building energy one of major sources warming, which can be controlled renewable installations. This paper deals an advanced evacuated hybrid solar photovoltaic–thermal collector (PVT) for simultaneous production electricity and domestic hot water (DHW) lower carbon emissions. Most PV...

In this numerical study the energy production in solar collectors a University building used to improve internal thermal conditions is made. Passive and active solutions, using external collector thermo-convectors, are used. The simulation, transient conditions, done for winter typical day with clean sky. This was carried out software that simulates Building Dynamic Response complex topology co...
