ORTECH can develop ground up solar resource assessment for input into the financial model. This will be completed in conjunction with the project design in order to advise the optimum selection of equipment, fixed or tracking racking systems for example. The resource assessment will use site specific solar resource information triangulated from nearby reference stations.

ORTECH utilized two industry standard software packages in order to estimate the solar resource at the Project site, Meteonorm and PVSyst. In combination, these tools provide a high quality estimate of the potential output of a solar array. The site specific weather data is then input to PVSyst, the software package that is used to estimate the potential energy generation from the solar farm.
