Data
The economics of any solar energy project are dependent on the solar resource at the location of the project. For reliable feasibility analysis of any solar project, accurate solar resource and meteorological data is required.
We offer high-precision solar and meteorological data to meet the requirements of each phase of your solar energy project - from pre-feasibility phase to operational phase. Based on our scientific knowledge, high-resolution data are calculated and made available via our in-house developed SolarGIS database.
| An independent Expert Survey (International Energy Agency, SHC Task 36 - Data cross-comparison) has identified the SolarGIS as the best database in the market, in terms of accuracy, reliability and data representativeness. |

Resolution of SolarGIS data
- Time period: 19+/14+/6+ years
- from 1994 for Europe, Africa and the Middle East
- from 1999 for America and most of Asia
- from 2007 for Australia, Japan, Korea and other Pacific countries
- Temporal resolution: 15 minutes (MSG satellite) or 30 minutes (other satellites)
- Spatial resolution: typically 250 metres (possible up to ~90 m)
More detailed information including validation statistics is available in the SolarGIS data specification document (PDF, 2.5 MB).
