Independent comparison of satellite and ground-based measurements ensures accuracy and consistency of solar resource data for developers worldwide Vaisala, a global leader in environmental and industrial measurement, has released the results of the world's largest solar dataset validation study undertaken to date. This extensive verification process, plays a critical role in ensuring that solar resource data stays accurate and consistent across the globe. In turn, it will support the efforts of international solar developers as the industry expands into important emerging markets within Asia, Africa and Latin America. The most recent validation paper, released today, compares observational data from nearly 200 ground stations across six continents with satellite derived irradiance records from five different versions of Vaisala's proprietary global solar dataset. The results of the study indicate that across the globe Vaisala's values for global horizontal irradiance (or GHI, the key variable for PV projects) have a standard deviation of bias error, more commonly referred to as the uncertainty, of 4.4-4.9% depending on the version of the dataset. To conduct a fair and unbiased study, Vaisala reserves ground station data exclusively for validation purposes and never uses data from these stations to calibrate or enhance the accuracy of its solar resource information.
