Maximizing Solar Efficiency in Bifacial PV Projects with Albedometers
Albedometer for Bifacial Solar Panels
Bifacial solar panels are designed to capture sunlight on both their front and rear surfaces, increasing the energy yield of a photovoltaic system. This added efficiency depends heavily on how much light is reflected from the ground or nearby surfaces—an effect that can vary based on environmental conditions like snow cover, surface material, or installation angle. To measure this reflected light accurately and understand how it impacts system performance, solar professionals use a device called an albedometer. An albedometer measures both incoming solar radiation and the irradiance reflected from the ground, allowing for a precise calculation of the albedo ratio—a key factor in determining how well bifacial modules will perform in any given location. SEVEN has developed a more accessible and affordable solution tailored to the needs of modern solar projects. The SEVEN PV Albedometer integrates two high-quality reference cells—one measuring direct irradiance, the other measuring reflected irradiance—within a compact, durable enclosure. It includes an internal temperature sensor to provide temperature-compensated irradiance readings, improving accuracy under changing weather conditions. For more advanced applications, the system also supports two external module temperature sensors designed in compliance with IEC61724-1 standards, enabling full Performance Ratio (PR) calculations for bifacial arrays. Whether you're working on a rooftop installation in an urban setting or a ground-mounted system in a snowy region, having accurate albedo data is essential for optimizing layout design, performance analysis, and energy forecasting. SEVEN’s PV Albedometer offers a practical and reliable way to gather this data, helping solar engineers, EPCs, and project developers get the most out of every bifacial panel they install.
