HELIOS 3D the universal System Solution for Solar Plant Layout

HELIOS 3D is amongst the most advanced planning tools for utility scale PV plants available on the market. Since over five years a steadily growing number of market leading PV system integrators are planning their international projects with HELIOS 3D (see References).

They are shortening parts of their planning work, which conventionally done, last perhaps days, to less than one hour. Despite of this they get results that take any aspect of the terrain into account, without any doubt.

HELIOS 3D allows shadow free placement of PV racks on a digital terrain at any geographical position and at any given date or time. This core functionality is controllable by the planner to any requirement with a lot of parameters. The analyzing functions of the terrain during project development and the evaluation of a first draft help to get an optimized and trusted layout much faster.

The workflow supports all phases of the project process. From starting with a fast and meaningful analysis and project development, over the planning phase with no stress from changes to the evaluation and construction, HELIOS insures a fast and secure transfer of the project into the field.



STÖHR+SAUER CAD- und Computer System GmbH, Germany, and Beijing RETEC Energy Technology Co., Ltd. Beijing, China, on 16. October 2014 have signed a contract for the distribution of the layout software "HELIOS 3D Engineering" in China.
