Electrical sizing of photovoltaic installations

Your photovoltaic installation sizing in real time:

Thanks to a few pop-up windows, archelios Calc offers quickly and easily a global and synthetic view of your photovoltaic installations: from the photovoltaic array to the grid, from the simple residential installations to the multi-inverters three-phase installations.

Taking into consideration all the components of photovoltaic installations, archelios Calc provides data on components’ compliance status thanks to a clear and good looking presentation.

STRENGHTS

• Professional solution for DC and AC electrical circuit sizing, single or multi inverters
• Security and conformity: calculations and normative controls (IEC or NF standards)
• Multi-manufacturers database for all the equipment (modules, protections, inverters, cables, surge protection devices, arresters, switches…) , more than 50 manufacturers with automatic filtering of the devices compatible with the installation
• Edition of personalized catalogues
• Independent treatment of the different components or editing in multi-selection mode for a flexible and quick design
• Real time calculation of the installation and visualization of anomalies
• Interactive use of Excel allowing to modify any object of the installation quickly (characteristics, locations, lengths…)
• Sizing of all types of PV installation
• Complete documentation of the installation for the commissioning and audit (calculation note, parts lists, cables lists, single-line diagram…)
• User-friendly tool, easy to learn with a synthetic display of the installation and a detailed contextual visualization for each element
• Including installations of more than 250kVA with a transformer connection via a Medium Voltage connection
• Export of data to the DWG format of the single-line diagram
• Import of the complete PV plant design from archelios Pro for its sizing

archelios Calc which was called until 2014 "solar calc", is developed by Trace Software International.

DISPLAYS IN REAL TIME:
• The complete and detailed synoptic table of the installation, where the validity of each component is reported thanks to a color code.

• An editing area which adapts automatically to the selected component. The edition can be done individually, for each component, or globally, through a multi-selection.
The characteristics of components can be integrated directly from the catalogues included in archelios calc or edited manually.

THE PHOTOVOLTAIC GENERATOR IS PRECISELY DESCRIBED
• Characteristics of panels
• Number and organization of panels
• Mini/maxi operating temperatures

THE ADAPTATION OF THE INVERTER IS OPTIMIZED ACCORDING TO:
• Power levels with possibility of upgrade
• Mini and maxi current and voltage levels
• Range of operating temperatures of solar modules
• Management of MPP trackers and inverters connexion points

CABLES ARE SIZED TO SATISFY THE DIFFERENT CONSTRAINTS
• Fire hazards
• Operating current
• Installation method
• Imposed maximal voltage drop (3%)

FUSE PROTECTIONS ARE OPTIONAL OR IMPOSED IF NECESSARY:
• Calculation of the admissible mini/maxi caliber
• DC assigned voltage

OPTIMIZATION OF THE INVERTERS
• Coherence with the connection to the public network (power, type, …)
• Calculation of the resulting currents (distribution of phases)
• Control of the load balance on the public network

CABLES ARE SIZED TO ANSWER TO THE DIFFERENT CONSTRAINTS
• Operating current
• Installation method
• Imposed maximal voltage drop (3%)
• Thermal constraint

SIZING OF PROTECTIONS
• Calculation of calibers
• Breaking capacity
• Thermal and magnetic thresholds
• Differential threshold according to the environment
• Operation time

SYSTEMIC STUDY OF SURGE ARRESTERS
• Evaluation of the need of surge protection devices according to the environment
• Automatic definition of surge arresters’ types and characteristics
• Control of the associated protections
• Determination of the section of grounding cables, and limitation to the junction lengths
