Abstract: In each region, weather conditions have a significant impact on the performance of photovoltaic modules, underscoring the need for specific data for each area, as in the case of Puno. To better understand this effect, a study was carried out in the town of Ayabacas, with the objective of evaluating the efficiency of two photovoltaic technologies during the dry and rainy season. Four photovoltaic modules were used, two with polycrystalline technology and two with monocrystalline technology. Two of these modules were exposed to dust accumulation for 12 months, while the other two were kept clean for reference. The power output was evaluated at both stations. During the dry season, it was observed that dusty modules experienced a slight reduction in efficiency compared to clean ones. For example, in the case of polycrystalline modules, the efficiency decreased from 3.11% to 3.07% with dust, while for monocrystalline modules, the reduction was from 3.28% to 3.23%. In the rainy season, the trend of reduction in efficiency for the dusty modules continued, although to a lesser extent than in the dry season. For example, polycrystalline modules experienced a decrease from 3.64% to 3.61% with dust, and monocrystalline modules from 3.83% to 3.77%. In addition, the maximum temperatures reached by the modules during both seasons were recorded. In the rainy season, the polycrystalline module with dust reached a maximum temperature of 48.58 °C, while the monocrystalline module with dust reached 46.3 °C. During the dry season, these maximum temperatures were slightly higher, with 48.62 °C for the dust-free polycrystalline and 47.44 °C for the dust-free monocrystalline.
