This document discusses how geographic information systems (GIS) can be used to plan and site solar energy projects. It describes Eolfi, a company that develops solar and wind projects. GIS tools like spatial analysis and elevation data are used to identify optimal locations based on slope, aspect, shadows, environmental constraints, and grid connectivity. The GIS model enables evaluation of potential sites and informs siting decisions to reduce costs and environmental impacts. In conclusion, the document states that GIS provides a practical and reliable way to map suitable areas and make more efficient siting decisions.

5. 3. Solar GIS
 Solar GIS is a tool aiming at talking
decision, capable of incorporating the
information, experience, and
know-how in the solar energy field.
 The integration of different skills
 reliable results.

6. 4. GIS Solar Model
 Understanding the needs of
development while respecting
the environment and each of
its aspects.
 Creation of spatial
connections between variables
• Grid Network - Capacity
• Distance to the grid
 Construction of the Solar
GIS model with the help of a
GIS software

7. 4.1. Concepts
 Goal
To make an orography map from raster and vector
data  Project Managers an able to build the layout
of the PV power plant
 Means
Arc GIS tools and Spatial Analyst extension
 Expected Result
Implementation area, that takes into account:
• Slope (Determines the feasibility and the pitch)
• Shadows (Forbidden areas)
• Obstacles (Trees, buildings, antennas …)
• Orientation (Irradiation losses)
• Environmental constraints (Natura 2000, RAMSAR…)
• Grid connection (Costs)

8. 4.2. Tools
DTM / DSM very high
resolution that allow us to
define the slopes, shadows,
aspects and visibility studies
Software for integration and
processing of graphics and
alphanumeric data
Cartographic Data
Tool for the measurement
of solar radiation
BD ORTHO ® Ortho photograph color and 50 cm resolution
25 SCAN ® Map at 1:25 000 standard

9. 5. Raster Elevation
Spatial Analyst is a performing tool that help to realize
important studies for PV, contours, slopes, aspect and
hill shade.
With this tool you can transform the vector-raster-vector

10. 5.1. Slope analysis
The slope map shows the sectors relevant to receive a solar
implantation and allows us to exclude the unsuitable land.
Depending on the shape of the terrain and the slope, the
PM will be able to identify the most appropriate solar
technology for the project.

11. 5.2. Aspect Map
The aspect map shows the relevant sectors which
orientation are important for us (All south).
This tool checks once again the relevance of the areas.
11

12. 5.3. Environmental studies and land occupation
Recover of data and analysis of environmental layers
that limit the study areas, for example Natura 2000.
This information allows us to identify the impact zones
next to our project.
12

13. 5.4. Grid connection and infrastructure
Identify the distance of the electrical connection points
which are next to the power plant and the road
infrastructure of the region.

14. 5.5. Results
 A solar implantation according to regulation
 A solar implantation integrated into the landscape
 Clean and safe electricity solution

15. 6. Conclusions
 Immediate, practical and reliable response due to the
performance of the GIS tool.
 Construction mapping that takes into account the territorial
and environmental restrictions.
 Geo referenced database that facilitates the information
transfer.
 Take decisions more efficiently thanks to a more efficient
mapping.
 Reduced time and costs of environmental studies, scoping
and territorial analysis.
