This paper discusses the design of an autonomous system for measuring the real technical potential of solar power, accounting for weather and climate impacts. A combined measurement system using the photoelectric method and additional sensors was designed to track weather data. The system integrates a photoelectric module, sensors for electrical parameters and weather metrics, temperature control, and data transfer to a web server. An experimental study conducted in Sevastopol demonstrated that the system can continuously monitor technical solar potential with at least 97% accuracy under varied environmental conditions. Key findings demonstrate that precipitation shading, pollution, dust accumulation on the photoelectric converter surfaces, and temperature fluctuations significantly influence technical solar potential. The maximum power measured during the study period was 65 W, with temperature deviations of up to 13 °C observed between the photovoltaic panel surface and ambient air. The system achieved a mean absolute error of 0.44 w and root mean square error of 0.62 W compared to reference measurements. It also streamlines the siting of solar plants while minimizing risk by objectively assessing a location's solar assets. |
