The success of any project that makes use of solar energy is directly tied to the amount of solar potential of the chosen location. To adequately plan such a project, a feasibility analysis becomes a priceless asset. Based on the most accurate solar and meteorological data, future projections are among our specialized products.

We offer state of the art solar and meteorological data that will serve as foundations for your project from the pre-feasibility phase to operational phase. Based on extensive scientific knowledge, high-resolution data is brought to you through our SolarGIS database.

An independent expert survey has identified the SolarGIS as the best database in the market, in terms of accuracy, reliability and data representativeness.
