This research investigates the factors that affect the production of electricity from solar cells. To determine the amount of electricity produced on a daily and monthly basis. Because the production of solar cells have been the most popular and widely used today. But there are several important factors that affect the production of energy is the uncertainty of the weather, which AJ power generation technology is not the same each day. In this study, the factors that affect the amount of solar power in the cause of the factors that affect the energy of the day, the temperature, light intensity, wind speed. We do a study using data to make. Analytical study the efficiency of electricity from solar farms in the summer and winter are. Differences in factors of climate, using data from the SCADA system of recording data every 1 hour of the solar farm. The study found that the weather on a daily basis that can affect the production of energy. Produced each day in addition to that, there are other factors that can cause the power has decreased as a cloud of dust type of panel installations including solar interior. There may be other factors that vary. These factors need to be continued. The electricity leg panel cells. Solar Energy efficiency and the amount of the maximum power.
