2. LEGAL BASICS
The basics for the realisation of entire European Union climate-
energy package of measures (worth 60 billion €) are action
programmes which have to be ratified by national parliaments.
In this context Slovenia will have to increase the part of
renewable energy resources by 2022 from 16% to 25%. This
way European Union will decrease the external dependence
from oil and gas and essentially increase energy security.
One of the most important alternative sources of energy is
photovoltaic which essentially contributes to friendly European
environment.

3. PROBLEM DEFINITION
In order to identify the necessary geoinfrastructure databases,
the entire process of operational photovoltaics had to be defined.
The process comprises 2 steps. In the first run the estimation of
the entire technical feasibility and economical investment are
elaborated.
If the estimation is positive then the second run is realised
which brings the project to the operational production of
electrical power.
This paper has the intention to show how the geomatics is used
in the first run in order to produce reliable technical and
economical results for later actual execution of the project. The
following abbreviations are used in the process diagram for the
geo databases:
solar illumination radiation - SIR
land cadastre and land register - LCLR
cadastre of buildings and land register - CBLR
environment protection plan - EPP
public infrastructure - PI
4. DETERMINATION OF COMPONENTS
4.1. Determination of the object
The object under consideration is determined either from land
cadastre or from cadastre of buildings with necessary attributes.
The ownership is identified from land register.
