en.Wedoany.com Reported - French company Trace Software has launched a new software called Elec Calc Solar, which can unify the DC-side design, power flow analysis, and complete electrical connection up to the medium-voltage grid connection point of a photovoltaic plant within a single modeling environment.
The company points out that traditionally, PV projects require separate tools for the DC (photovoltaic) part and the AC (electrical) part. This fragmented design approach often leads to inefficiency, rework, and inconsistencies in technology and specifications. The new tool, Elec Calc Solar, features free-form modeling, allowing designers to complete the entire electrical design from the PV string to the grid connection point, while integrating functional modules such as self-consumption, electric vehicle charging, energy storage, low-voltage distribution boards, and even medium-voltage grid connections.
On the DC side, the software integrates sizing design functions compliant with the IEC 60364-7-712 standard, covering string and MPPT input configuration, inverter selection verification, DC cable calculation, electrical protection, and surge protective devices. On the AC side, the software integrates all low-voltage parts according to the requirements of the REBT (Spanish Low Voltage Electrical Regulations), supporting the design of distribution boards, circuits, protective devices, and related loads, including electric vehicle charging systems and self-consumption schemes.
Elec Calc Solar is also equipped with advanced grid calculation capabilities, enabling multi-source power flow analysis, voltage drop calculation, short-circuit current calculation, lightning studies, and supports connection via medium-voltage transformers, extending the study scope to the medium-voltage network. Thanks to the free-form modeling approach, users can configure complex architectures such as industrial rooftops, solar carports, or ground-mounted power plants without being constrained by predefined fixed templates.
The software features real-time regulatory compliance checks, automatically identifying thermal overloads, protection coordination errors, or excessive voltage drops. All technical documentation, including calculation notes, single-line diagrams, bills of materials, and compliance reports, can be automatically generated from the same platform. Furthermore, Elec Calc Solar maintains a direct data link with the company's PV design software, archelios Pro, allowing direct import of completed PV architecture designs without the need for data re-entry. It can also integrate with Elec Calc HT/BT, BIM, and GRID modules to achieve more advanced medium-voltage protection design through digital relays.
