TL;DR: In this paper, a hybrid system, which is a combination of an air heater and photovoltaic system is analyzed, and the optimum area of the solar cells necessary to generate sufficient electrical energy for the pump is calculated for different configurations of the air heater.

TL;DR: In this article, the authors presented a theoretical study of a solar photovoltaic-thermal (hybrid) system consisting of a flat-plate solar air heater mounted with solar cells and a plane booster.

TL;DR: In this article, the transient equations of three types of air heaters are written and their solutions are attempted and the effect of flow rate, plate length, selective coating, etc.

TL;DR: In this article, a water heater utilizing a material which changes phase for storage of solar energy is discussed, and transient analysis is carried out by replacing the solid-liquid block of the phase-changing material by a fictitious solid and assuming that the solid liquid boundary remains stationary throughout the day.

TL;DR: In this paper, an air heater in which the air first flows between metallic and cover plates and is then made to flow between two metallic plates in opposite direction is discussed theoretically, and the governing equations of the model are solved explicitly under suitable conditions.
