This paper presented a performance analysis of two photovoltaic modules with polycrystalline cells model SUNTECH STP022-12/D. The panels has ten years of use. Making up the experiments on Renewable Energy Center, State University of Guaratinguetá - SP and making up the calculations with data obtained, the panelselectric-solar performance values are alsoobtained. For data collection, the experiments were developed using six coolers as cargo of photovoltaic panels. Voltage measurements were raised, with and without load, and of current with load, of the panel terminals, and solar radiation incidence measured in the direction perpendicular to the face of the panel. These measurements were performed to calculate the electric-solar performance of the panels. There were also measured environmental and photovoltaic panels temperatures. To assist the best orientation of photovoltaic panels were used an inclinometer and a compass. The tests were performed in four different climatic conditions: partly cloudy day, day with few clouds, sunny day with ambient temperatures mild and sunny day with high ambient temperatures. The results indicated atrend of higher power generated with higher solar incidence. The environment temperature did not show a proportionalvariation with solar incidence. For values of incidence higher than 700W / m², the performance of panel showed a smallvalue decrease with the incidence increases, while for solar incidence values smaller than 300W / m² the performancevalue decreased a lot
