SPAC EasySol 26: the CAD software for photovoltaic design and budgeting gets an upgrade

More automation, advanced calculation tools, and a fully integrated ecosystem: the new release simplifies the daily work of photovoltaic professionals.

SDProget Industrial Software presents SPAC EasySol 26, the new version of the CAD software dedicated to the design and budgeting of photovoltaic systems. This major update introduces new features aimed at making the work of designers more accurate, faster, and customizable.

From site inspections to the preparation of technical and economic documentation, SPAC EasySol 26 proves to be a complete tool, capable of managing the entire process with consistency and continuity. The software integrates seamlessly with EasySol Configurator and EasySol Mobile, creating a real-time communication ecosystem between PCs and mobile devices, for an uninterrupted workflow.

Simplified design, more accurate results

The new release brings significant improvements to the automatic drawing of single-line and multi-line diagrams. Thanks to updated graphic libraries and over 1,100 AutoCAD symbols dedicated to photovoltaics, SPAC EasySol 26 automates repetitive tasks while giving designers full control over technical details.

Key new features include:

  • Enhanced single-line diagram generation.

  • Bill of materials output in Excel or tabular format.

  • Management of heterogeneous strings and Multi-MPPT configurations.

  • Automatic insertion of module, inverter, and accessory descriptions into drawings.

  • New tools for generating DWG layout drawings, complete with legends, dynamic numbering, and scaled outlines.

Technical calculations and bidirectional design: maximum flexibility

One of SPAC EasySol 26’s strengths is bidirectional design, allowing users to start from either the PV modules or the inverter. This flexibility makes it adaptable to any operational scenario, improving both speed and precision.

Enhanced features include:

  • Automatic calculation of annual and monthly energy yield.

  • Shading loss analysis, with the option to upload photos for realistic simulations.

  • Utility bill and self-consumption analysis, comparing produced and consumed energy on a monthly basis.

  • Automatic suggestion of the most suitable PV generator based on consumption data.

  • Integration with the new Google Earth MAPS feature, enabling accurate surface area estimation for installations.

Advanced and customizable component database

To support increasingly accurate design, SPAC EasySol 26 includes an updated and customizable material database:

  • Comprehensive archive of modules, inverters, optimizers, and storage systems, with datasheets accessible directly from the software.

  • Manufacturer-specific compatibility management.

  • Preconfigured storage kits, including accessories linked to graphical symbols.

  • CAD libraries for inserting scaled outlines and intuitive topographic drawings.

Tailored Business Plan: design meets financial analysis

Now more than ever, photovoltaic system design must be paired with economic evaluation. With Release 26, the SPAC EasySol Business Plan evolves to offer advanced and customizable financial simulation tools.

The software enables the calculation of:

  • Cash flow, payback period, IRR, and NPV automatically.

  • Profitability scenarios based on sales, tax deductions, depreciation, and operating lease.

  • Simulations specific to Renewable Energy Communities (REC), including benefit analysis for all participants.

  • Reports in Excel, DOC, and PDF formats for clear, professional presentations.

Special focus has been placed on operating lease management, a financing method increasingly in demand, with direct impact on cash flow and tax benefits.

EasySol Mobile: surveying and quoting on the go

The new version of the EasySol Mobile app, available for iOS and Android, streamlines mobile surveying and quoting. With an intuitive interface and enhanced functionality, it allows users to:

  • Conduct surveys with automatic geolocation, determining site orientation and tilt.

  • Calculate real-time energy yield using ENEA and UNI climate data.

  • Eliminate the use of paper forms by sending data directly via email to the desktop software in EasySol format.
