Abstract
One of the best ways to identify and design a system is simulating and to achieve this goal, we use simulation software such as MATLAB Simulink. In this study, the relations ruling photovoltaic is described. Then, on the relations basis, a photovoltaic system is simulated in MATLAB software. After photovoltaic system simulation, regardless the specific geographic area, radiation and temperature effect on photovoltaic system is generally simulated. Finally, with regard to radiation and temperature values effect on, it was concluded that we overlook the temperature effect than radiation effect on photovoltaic system designing. It certainly does not mean overlooking the temperature effect. It means a low-effect power changes per temperature changes against radiation.

Summary
The performance of a photovoltaic panel generally depends on the radiant energy amount received to it. Razhaghi and mosavi reported (2013) photovoltaic systems study and simulation by using MATLAB Simulink and radiation or temperature input reflects the enormous changes of Maximum power point [4]. In continuation of previous research in this study, it is discussed the photovoltaic system analysis relations and after introduction of effective relations and simulation these relations in MATLAB software, the effectiveness amount of radiation and temperature factors on photovoltaic systems are studied. In figure 1, first block diagram represents physical behavior of a photovoltaic panel that normally its output is nominal voltage and current values. The second block diagram represents current and voltage regulators (limiter) to achieve value This limiter role is locking output on peak of the curve. By applying the above contents, figure 2 circuit is resulted
