Italy’s solar industry is expanding rapidly—adding over 6.8 GW in 2024 alone and pushing total installed capacity past 37 GW. From Lombardy rooftops to Sicilian ground-mounts, solar is booming. But so are the complexities.
Italian installers and EPCs aren’t just expected to design high-performance systems—they’re also navigating a maze of incentives: Superbonus 110%, Ecobonus, Scambio sul Posto, regional funding schemes, and more. Throw in eInvoicing, GSE documentation, and tax compliance, and the design process often turns into a paperwork nightmare.
Most teams are still stitching together CAD software, spreadsheets, third-party tax advisors, and PDF templates. The result? Slower quotes, lost time, and missed incentives.
This guide compares the top solar software tools for Italy in 2025, focusing on what really matters: shading precision, Italian proposal exports, incentive modeling, and speed-to-contract. One tool—SurgePV—stands out for unifying everything from design to GSE-ready outputs in a single Italian-optimized platform.
What Italian Installers Actually Need
Designing solar systems in Italy isn’t just about watts and panels—it’s about navigating an intricate web of national and regional regulations, incentive deadlines, and financial compliance. The best solar software in 2025 must do more than draw on rooftops—it needs to deliver compliant, bank-ready documentation and savings proof in real time.
Support for Superbonus 110% and Ecobonus is essential. Installers need tools that can model these incentives automatically—tagging eligible components, splitting financial outputs, and generating deduction-compliant reports.
Scambio sul Posto simulations are another must. Tools should estimate how much energy will be self-consumed, exported, and reimbursed under net-billing policies—something Excel simply can’t handle accurately.
With regional grants varying from Lazio to Puglia, ZIP-level incentive logic is no longer a luxury—it’s a necessity. Add to that Italy’s complex topography and historical urban architecture, and LIDAR-based shading tools become critical for accurate forecasts.
Lastly, installers need platforms that produce proposals in Italian, include legal clauses for GSE, and output in formats that match certified eInvoice workflows. Combine that with a CRM, digital signature, and payment integration—and your sales cycle goes from weeks to hours.
A true Italian solar software doesn’t just model systems—it models savings, incentives, and speed.

Frequently Asked Questions – SurgePV for Italy
Does SurgePV support Superbonus 110%, Ecobonus, and regional grants?
Yes. SurgePV’s Italian-specific incentive engine dynamically calculates Superbonus 110%, Ecobonus, and regional incentives by ZIP code. It automatically checks eligibility criteria (e.g., property type, system size, usage class) and embeds the deductions into the financial outputs. Installers no longer need to toggle between Agenzia Entrate tables, tax PDFs, or separate spreadsheets—SurgePV handles it all.
Can SurgePV simulate Scambio sul Posto and model energy resale?
Absolutely. SurgePV includes a Scambio sul Posto simulator that models net-export energy, self-consumption ratios, and the resulting financial impact. It pulls regional utility rates and resale assumptions into the ROI calculation—ensuring accurate, bank-ready savings reports for both residential and commercial systems.
How accurate are the LIDAR shading models for Italian rooftops?
Exceptionally accurate. SurgePV processes high-resolution LIDAR to generate per-panel shade maps—detecting obstacles like dormers, chimneys, and nearby structures. This is especially useful in dense urban areas or historical zones like Rome, Bologna, or Florence, where roof complexity demands more than basic satellite tracing.
Can I issue Italian-language eInvoices and proposals from the platform?
Yes. SurgePV exports proposal PDFs, contracts, and invoice-ready files in native Italian—pre-filled with legal clauses, itemized incentives, and compliant formatting. XML compatibility for eInvoicing is in progress, aligning with Agenzia Entrate standards.
How much faster is SurgePV compared to CAD + Excel?
Dramatically faster. Italian EPCs have reported reducing their quote + proposal process from 2–3 hours to just 15–30 minutes. By merging design, simulation, incentive logic, and proposal export into one interface, SurgePV removes manual steps and speeds up the full quote-to-contract cycle by up to 85%.
