Based on the energy balance and conversion principle

a thermal and electrical model for the solar photovoltaic/thermal (PV/T) system is developed to solve coupled thermal and electrical parameters by using the iteration method of MATLAB. The variation of thermal and electrical efficiency is given and the influence of the PV/T system assembly length and working medium velocity change on the performance curve of the PV/T system is analyzed. Experimental study is conducted to compare the simulated results with the experiment data of general photovoltaic assembly including voltage

current

power and temperature of the back panel.
