The importance of albedo

As bifacial modules proliferate, estimations of albedo are becoming more important and with developers not prepared to install weather stations to assess solar resource, a popular option has become third-party, on-site measurements over periods as short as a day. Is this an acceptable compromise between costly on-site measuring and less accurate satellite data? Everoze’s Stefan Mau discusses the potential benefits and limitations of this approach.

Although an accurate assessment of solar resources is key to ensuring the reliability of an energy yield assessment, most studies rely exclusively on satellite irradiation data. Solar developers rarely dedicate resources to installing a weather station to obtain ground-measured data before PV project construction, mainly because of the significant costs involved. Operating a weather station …
