In the PV system with storage batteries, as a maximum power point tracking (MPPT) device is used to enhance battery charging, the enhancement must be greater than the internal loss of the device itself, or there will be no net gain at all. To evaluate the MPPT device benefits under different...

In this paper, heat transfer and flow in a lean-to passive solar greenhouse has been studied. A mathematical model based on energy equilibrium and a one-dimensional mathematical model for the unsaturated porous medium have been founded and developed to predict the temperature and moisture...

In this paper, the chimney is assembled with porous absorber for the indirect-mode solar dryer. Local thermal non-equilibrium (LTNE) exists in the porous absorber, so the double energy equations and Brinkman–Forchheimer extended Darcy model are employed to analyze the heat transfer and flow in...
