The hybrid solar system assumed to be consist of thermoelectric generator (TEG) and evacuated tube with efficiency extracted under standard condition of 1000 w/m2and ambient temperature 25 C, then the efficiency of hybrid system measured at different solar radiation and temperature. In addition the thermal efficiency and electrical efficiency are extracted. The study was done with different figure of merit (ZT) (0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4) of thermoelectric generator (TEG). The heat transfer coefficient of evacuated tube 0.89 W/k.m and temperature dependent that transfer coefficient 0.001w/k2. m the calculation and graphs were done by MATLAB program
