Industrial process heating applications in the temperature range of 50°–250 °C consumes about 35% global fossil fuels, wherein solar thermal is envisaged as an alternative option. Outlet temperatures both flat-plate collector (FPC) and photovoltaic (PVT) are not high enough to serve industrial processes. In this article, a assisted (SAPH) system, FPC integrated series with PVT, has been designe...

There is a renewed interest in photovoltaic solar thermal (PVT) hybrid systems, which harvest solar energy for heat and electricity. Typically, a main focus of a PVT system is to cool the photovoltaic (PV) cells to improve the electrical performance, however, this causes the thermal component to under-perform compared to a solar thermal collector. The low temperature coefficients of amorphous s...

Solar air heater is a type of heat exchanger which transforms solar radiation into heat energy. The thermal performance of conventional solar air heater has been found to be poor because of the low convective heat transfer coefficient from the absorber plate to the air. It is attributed to the formation of a very thin boundary layer at the absorber plate surface commonly known as viscous sub-la...

In Canada, more than 80% of energy in the residential sector is used for space heating and domestic hot water (DHW) production. This study aimed to model compare performance four different systems, using solar as a renewable source DHW A novel microchannel (MC) thermal collector microchannel-based hybrid photovoltaic/thermal (PVT) were fabricated (utilizing heat exchanger both cases), mathemati...

Solar-heated air can be used in a wide variety of applications, but it is a limited resource. Only so much sunshine strikes each square foot of the earth, and a well-built collector system will typically deliver about half of this energy to a house in the form of heat. The way this heat is used often means the difference between a useful, cost-effective system and one that never seems to perfor...

An integrated energy system for office buildings is examined, with the use of a numerical tool that has been developed simulating renewable energy-based systems based on geothermal and solar energy. The main components are PV-Thermal (PVT) collectors, several boreholes form ground heat exchanger multi-source pump supplied by either from ambient air or water. code in Python used detailed investi...
