Abstract: This paper presents mathematical model of temperature distribution in solar thermal which performs in second-order partial differential equation. Solar thermal analysis uses copper absorber, aluminum absorber, and anodized aluminum absorber to compare temperature distribution of water in pipe from three types of absorber. The paper simulation using 3-D finite element method that all the coded developed by MATLAB program and show the graphical represent for temperature which varies with time of glass, absorber, pipe, water, foil, and foam temperature in various type of absorber.

Keywords: Solar thermal, 3-D finite element method (3-D FEM), computer simulation, temperature, absorber
