Meteorological data includes the conventional ground meteorological data and the solar energy resource radiation data. In the actual development of photovoltaic power generation projects, most investors use the radiation data from relevant meteorological databases to calculate the photovoltaic power generating capacity. At present, NASA and Meteonorm are the main sources of solar energy radiation data for early site selection and revenue estimation of photovoltaic power stations. They are the industry standard of solar resource query software in the photovoltaic industry.

Meteonorm is a professional and powerful global historical meteorological information query & analysis software developed by Meteotest from Switzerland. Its database is provided by tens of thousands of weather stations and several geostationary satellites around the world, thus ensuring the authenticity and reliability of data. Meteonorm is suitable for engineers, architects, teachers, planners and anyone who are interested in solar energy and meteorology to use.

As an integrated meteorological database used for solar applications and system design, Meteonorm is a unique combination of reliable data sources and complex computing tools. You are allowed to choose from dozens of different weather parameters as needed. The program can calculate the solar radiation value on an arbitrarily oriented surface at any location. That is, input the latitude and longitude coordinates of a project site to easily obtain the average monthly total radiation in the region for decades.

In contrast, most of the time NASA’s data is higher than Meteonorm’s, with the maximum being more than 10%. Therefore, it is recommended to use Meteonorm’s data when calculating solar power generation. Or, if you find that NASA’s weather data isn’t accurate enough, then give Meteonorm a try. Meteonorm’s data is more accurate than NASA’s especially when the source of data can only be satellites. BTW, for photovoltaic power design software, you can ask PVsyst for help.
