The pictures demonstrate layout of solar panel, in which displayed simply operation system by tranfromed some variable (Sun rays) according to the reference pictures.
Overall, in the first pictures at above show compenent of the panel by straightforward method, having seperate its each part such as transparent glass,inlet and outlet. On the other hand couple pictures below both of it displayed operation system of 2 variable namely air and water where the major things on experiment. The left articulate how sun rays from the sun shine throught the transparent glass by added the air into an inlet of instrument. This can be obviously saw that the water have chemical tranformation, which repurcussion be showed from normal temperature of air turned to warm air after passed the process of this panel. At the same time, the right picture showed another variable was water,which used the same proceed similar with the left one.
To summarize, the charts are illustrated to tranformation forms by throught some variable from solar panel, which having the sun rays had main attacking to the apparatus.
