Modeling of a novel Trombe wall with PV cells

A novel Trombe wall with PV cells is presented in this paper. A two-dimensional model of PV glass panel and a model of the PV-Trombe wall system are established. The temperature distribution and electrical performance of the PV-Trombe wall system are also obtained. Results show that according to the measured weather data and the special simulation condition, the temperature difference between the elements with and without PV cell on the glass panel reaches a maximum value of 10.6 C; the temperature difference between the room with and without PV-Trombe wall reaches a maximum value of 12.3 C during 3 days; after 7 days’ operation, the all-day temperature of the room with PV-Trombe wall retains at about 13.4 C and an increase of 5.00% for the electrical efficiency can be achieved.
