The application to PVGIS brings important improvements relative to the existing solar radiation databases within PVGIS.
Details of the Method The GIs database covers two regions in different ways: European subcontinent:• The PVGIS-SARAH cloud model has a lower resolution than the Solcast model, based around a 5 km 2 grid.
Includes aerosol impacts tracking of smoke, dust, haze• We have developed the largest collection of solar resource maps to help the solar industry with development of solar projects.
Next article in issue• Owing to their continuous structure, the main results and parameters of this project are often presented as coloured maps at regional or continental level New database Climate-SAF PVGIS These data are based on calculations from satellite images performed by CM-SAF Geostationnary and.
RMSE, a measure of the differences between the values predicted by the Solcast model and the values actually observed, shows strong model performance.
Available for selected countries only.
Note that main solar panels are fitted with crystalline silicon cells monocristallin or polycristallin.
Typical Meteorological Year data for nine climatic variables.
Previous article in issue• The area covered by the calculator is almost the world : America, Europe, Asia and Africa.
In this way they have data for any location over large geographical areas with hourly time resolution | As a photovoltaic Geographical Information System it proposes a googlemap application that makes it easy to use |
---|---|
For systems connected to the grid : PVGIS for PV grid-tied systems almost anywhere in the world America, Asia, Africa and Europe Via the Google map it is possible to calculate the solar energy generation for a Grid tied PV system | The CM-SAF solar radiation database is characterized by very low overall bias and shows good accuracy at validation sites |
No RMSE data was available for PVGIS-SARAH | To download free softwares see this section: or NEW : Now PVgis covers also America USA, Brasil, Colombia, Peru, Mexico |
Consulting Solcast provides global coverage of historical solar datasets | Without the provision of recent data, developers are not able to make one-to-one comparisons with ground observations to better understand the accuracy of data |
Solar maps for Google Earth Desktop Map data are served as high-resolution images, provided in a format suitable for viewing and analyzing in a desktop version of Google Earth software | |

You can find more details on the Solcast dataset on the page | At the moment there are three different satellite-based databases available |
NSRDB data is available only until 2016 | When decisions on development or operation of high-value solar assets are to be made, higher risk associated with the use of high-uncertainty data can be very expensive |
