Evaluation of suitable terrains for solar plants becomes an essential part in solar project development. Therefore a system that can do this, is of high value. HELIOS 3D has functions to qualify land with ease, that you normally would not consider to be in the useable range. With a few mouse clicks all essential values are checked.
Sources for this information are manifold. For higher accuracy you can purchase data from local authorities or in the U.S. from the U.S. Geological Survey (USGS). These digital cartographic/geographic data files are produced as part of the National Mapping Program and are sold in different resolutions.
For higher demands during development STOEHR+SAUER provides a data service for Western Europe and North America with a higher precision and a raster width of 6 yards. This data is available within a day (Picture 2). During the final phase, where precise data is necessary, land survey is the best way, because you will also get break-lines for fine details. The quality of the results of our calculations depends on the quality of the terrain data.

Meaningful presentations and documentation are just a few mouse clicks away. The specific characteristics of a terrain can be easily assessed.
HELIOS 3D has comfortable, intuitive analysis tools to achieve this even in 3D. Marking which parts of the area have north, south, east or west orientation (Picture 3) helps select optimal areas. The angle of slope analysis (Picture 4) shows where hydraulic ram machines can be used or their technical specifications are exceeded.
The elevation analysis gives a better understanding of the structure of the terrain. Additional possibilities come with Civil‘s rain drop analysis, and slope arrows functionality also show where erosions could take place.

For the experienced developer it is easy to roughly subdivide the terrain and set keep out areas for technical equipment or access roads. For a first estimate in these areas a standard rack is placed and thus a fast potential installable peak power is obtained. Variations are made quickly and can be easily evaluated and compared (Picture 5).
