With the Solarius PV 3D objects:

quickly define the building footprint, surfaces and obstacles;
use the dedicated objects for representing "Electrical switch-panels", "PV generators" and "Inverters";
detail your PV system design by using objects available for free in the extensive online collection of 3D Models, import SketchUp^®, OBJ, 3DS, etc. file formats.

The 3D modelling process allows you to identify installation surfaces for your photovoltaic modules with a simple click. Check the correct positioning of the photovoltaic field in real-time and in relation to the true conditions of the installation site (inclination, orientation, irradiation, shading, etc.).

3D input to model the photovoltaic system | Solarius PV | ACCA software

3D objects input to design any type of photovoltaic system

With Solarius PV, use 3D objects to quickly model the building's volume footprint, define the PV field installation surfaces and the presence of any obstacles present (chimneys, roof dormers, pylons, etc.) even without any further graphical support.

It doesn’t matter how complex the existing building is: using the "volume" and "inclined surface" objects you can easily model any type of situation directly in 3D even using AutoCAD^® DXF/DWG file formats.

3D modelling offers you the advantage of being able to check your system layout and positioning in real time and for all periods of the year, according to the real conditions of the installation site (inclination, orientation, radiation, shading, etc.)

In the case of ground mounted installations, once the site is correctly schematized, easily enrich the project with various types of "3D Models" of canopies, shelters and other photovoltaic support structures. If you need specific objects, even import your own 3D Models into the project with full support for many widely used 3D model formats (SKP, OBJ, 3DS, etc.)

Complete the design with dedicated objects for representing "Electrical switch panels", "Photovoltaic generators" and "Inverters" inserting them in the 3D model with maximum freedom.

Integration of photovoltaic system with BIM model and architectural project | Solarius PV | ACCA software

Integration of the photovoltaic system with the BIM model and the architectural project

In addition to importing DXF or DWG drawings with Solarius PV you can also:

import the project as a BIM model of the building or installation site directly as an IFC file produced with any BIM design authoring software such as: Edificius, Revit^®;, ArchiCAD^®, AllPlan^®, VectorWorks^®, etc.)
design the photovoltaic system directly on the imported model using the 3D parametric objects containing all the information necessary to complete the building information model.
export the photovoltaic system BIM model as designed in IFC file format to continue the design workflow of the digital construction model as required by the BIM process philosophy

Solarius PV adopts the IFC standard by buildingSMART international, the only format that can provide assurance of correct file creation, management and data, documents and models sharing among all subjects involved in a given project.

If you need to reach a high standard of activity sharing with all collaborators involved in design, construction and maintenance of the photovoltaic system and the building, you can even integrate your Solarius PV project into the usBIM.platform collaborative platform.

Assisted design of the photovoltaic field

With Solarius PV locate the photovoltaic installation surface with a simple click.

From the selected object, the necessary installation surface is extracted with the automatic recognition of orientation and tilt data.

The identified surface will be automatically filtered from any obstacles that may be present (includimg chimneys, dormers, balustrades, trusses, lighting poles or holes and obstructions) to obtain the correct positioning of the photovoltaic field.

Once the surface has been identified, the software helps you select the correct number of modules based on the defined design criteria. You can, for example, opt for a solution that maximizes annual production rates or simply go for maximum power output, etc.

Define more than one installation surface directly on the 3D BIM model (roof, shelter, canopy, flat roof, ground, etc.) on which to install multiple photovoltaic fields.

FAQ

With Solarius PV can I design any type of photovoltaic system?

Yes. Solarius PV is a complete and versatile tool that allows the technical and economic design and evaluation of any type of system and size:

integrated roof systems;
facades or sunscreens (brise soleil) of new or existing buildings;
installations on terraces on buildings or ground level terraces;
photovoltaic farms also with "sunflower" type panels;
systems mounted on parking shelters, canopies or similar, etc.

Can I produce a quick financial analysis of a system even without completing the entire system design?

Yes, Solarius PV allows you to produce a preliminary economic evaluation of your project and therefore it isn’t necessary to complete all phases of technical design.
Simply specify general installation site info, define available installation surfaces and in a very fast and accurate way you can get the relevant photovoltaic energy production rates. The financial analysis can be completed with a detailed estimate, by means of special load profile archive, energy consumption (PV electricity consumption or withdrawn from the network) with the detail of daily time periods and for different periods of the year.

Does Solarius PV allow you to create new locations for irradiation data calculation?

Yes, the software already has a database of cities for many nations of the world, all provided free of charge and include the largest and most professional solar irradiation data as Meteonorm^® (integrated and free) for the whole world and PVGIS for Europe, Africa, the Mediterranean Basin and South-West Asia.
Furthermore, it is always possible to define new locations.

How is the choice of modules, inverters and batteries in Solarius PV made?

The software allows you to optimize the design of photovoltaic systems based on the actual available surfaces and/or the customer’s energy needs.
You choose to optimize production in order to take advantage of the entire available area or, in alternative, in relation to the power or specified energy requirement. Solarius PV guides the user by showing only the modules, inverters and accumulators for which all electrical tests are satisfied. This simply means that photovoltaic system design becomes faster and safer.
Of course, if you want to use a specific photovoltaic module or a specific inverter, even if not present in the library, the software allows the user to add it proposing only the photovoltaic field composition (number of strings by number of modules) that satisfy all electrical checks.

Can I insert new modules, inverters, accumulators in the Solarius PV libraries?

Yes! The extensive library of components is freely customizable.
Once you have defined your modules, inverters and accumulators, you can also choose to use only the inserted elements in all new projects.
