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.

digital orthophoto - DOF

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.
