Abstract :The aim of this paper is to estimate the efficiency of photovoltaic insert ignore into journalissuearticles values(PV); panels with and without active cooling by using genetic expression programming insert ignore into journalissuearticles values(GEP);. An active cooling system has been developed based on water spraying insert ignore into journalissuearticles values(non-uniformly); of PV panels, and we provide to increase the efficiency of PV panels. Panels is not cooled, the temperature of the panel is increased and the efficiency was calculated as 16.81%. When the panels are cooled, the panel temperature fell and the efficiency was calculated as 18.83%. GEP is preferred since it generates a mathematical function which fits to given experimental data. The test results indicate that for the model equations obtained, the determination coefficients insert ignore into journalissuearticles values(R 2 ); are very high. These good agreements confirm the validity of the developed GEP models.
