Albedometer The Albedometer is part of the SEVEN meteorological sensor range, which includes professional and intelligent measuring sensors for environmental and industrial applications such as PV plants. The albedometer simply consists of two irradiance sensors, where the front sensor measures the incident POA irradiance and the rear sensor measures the reflected irradiance. It helps to calculate the performance ratio and measure the solar albedo. Solar albedo is the ratio of reflected irradiance to POA irradiance. The albedometer is designed for professional use in photovoltaic plants that use bifacial panels. The measured values can be transmitted to dataloggers and receiving units via the serial RS485 interface with MODBUS RTU protocol. SEVEN products use reliable and high-quality components to provide accurate meteorological data. The albedometer is specially designed according to the requirements of PV plant monitoring systems. • Class A Compliance • Free Software Update • Similar Structure with PV Modules • SEVEN Remote Setup Service • Fast & Simple to Install • SEVEN Customer Support • Low Power Consumption • 2 Year Warranty • 2 pieces PT1000 Module Temperature Sensor Connection (Optional) 3S-ALBEDO The 3S-Albedo Albedometer is designed for professional use in industrial, commercial, and utility-scale photovoltaic plants. All measured data is transmitted to data loggers and receiving units via a 3-wire RS485 data bus using the Modbus RTU protocol. For bifacial systems, the measured albedo value can be used as a reference in calculating the site’s performance ratio (PR) and in overall performance analysis. The 3S-Albedo-2T Albedometer is designed for professional use in industrial, commercial, and utility-scale photovoltaic plants. It functions as a hub that allows the connection of two PT1000 module temperature sensors. All measured meteorological data is transmitted to data loggers and receiving units via a 3-wire RS485 data bus using the Modbus RTU protocol. For bifacial systems, the measured albedo value can be used as a reference in calculating the site’s performance ratio (PR) and in overall performance analysis. Pinarcay OSB Mahallesi 11.
