Creation of spatial connections between variables • Grid Network - Capacity • Distance to the grid

Understanding the needs of development while respecting the environment and each of its aspects.

Construction of the Solar GIS model with the help of a GIS software

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) 7

4.2. Tools4.2. 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

BD ORTHO ® Ortho photograph color and 50 cm resolution

25 SCAN ® Map at 1:25 000 standard

Cartographic Data

Tool for the measurement

of solar radiation

With this tool you can transform the vector-raster-vector

Spatial Analyst is a performing tool that help to realize important studies for PV, contours, slopes, aspect and hill shade.

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.

5.2. Aspect Map5.2. 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.

5.3. Environmental studies and land occupation5.3. 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.

5.4. Grid connection and infrastructure5.4. 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.

6. Conclusions6. 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.
