The purpose of this study is to determine the optimal direction and slope for installing photovoltaic panels in Kashan city. For this purpose, using the geographical location of the area, the relationships and physical model of Masters Gilbert, the received solar radiation on the panel surface was calculated. The results of this study show that in sixty-four percent of the time of the year, the amount of radiation received on the collector surface in the south direction and on different slopes is more than the radiation on the panel surface installed in the direction. Southeast or Southwest with different slope angles. Most of the radiation in the azimuth facing south is on a slope of 30 degrees and 40 degrees, the southeast-west azimuth (30 degrees) is almost similar to the south azimuth, and only in the south-east-west direction, in summer, slopes close to vertical, receive more radiation than in the south direction. The amount of radiation received on the panel surface in the southeast-west direction (azimuth 60 degrees) on different slopes, in 87% of the times of the year more than the radiation on the panel surface installed in the east or west direction (azimuth 90 degrees) with the angle of the slopes It's different. Comparing the results, it is clear that the more the direction of installation of the photovoltaic panel changes from south to east or west, the more the radiation intensity will decrease on the days of the year. The highest efficiency of photovoltaic energy production in Kashan city, in the direction of the south, and with the installation angle of photovoltaic panel, is 30 degrees relative to the horizon line. Also, the most suitable slope for installing panels, between 30 degrees and 40 degrees, was obtained compared to other slopes.
