TL;DR: SurgePV is the only platform covering both Law 27,424 customer proposals and RenovAr utility-scale tender bids in one integrated workflow. OpenSolar is the affordable pick for residential-only installers. Solargraf wins on native Spanish interface. Aurora Solar has the best visual proposals but at 2-4x the price. Energy Toolbase is too US-focused to matter for most Argentine projects.
Argentina’s distributed generation market has grown fast. From fewer than 100 registered Law 27,424 installers in 2017, the count now exceeds 500. Every one of them is pitching residential and commercial customers in Buenos Aires, Cordoba, and Mendoza with rooftop solar proposals.
On the utility-scale side, RenovAr has contracted over 4.5 GW across four auction rounds. These tenders demand detailed bid packages: 20-year PPA financial projections, CAMMESA interconnection documentation, bankability summaries, and 30-40% local content compliance reports.
Two very different proposal needs. One market.
Most solar proposal software was built for the US residential market. Clean templates, AI roof renders, quick PDF exports. That works fine for a homeowner in Arizona. It falls apart when you need accurate net metering calculations at wholesale market price (roughly 0.7x retail tariff), provincial variation modeling for Buenos Aires versus Cordoba versus Mendoza, or a complete RenovAr tender bid package with CAMMESA-compliant single-line diagrams and P50/P90 bankability summaries.
Then there is the peso. At roughly 850 ARS/USD with annual inflation running 100-150%, software priced at $60-200/user/month translates to 51,000-170,000 ARS per user per month. For a small installer in Cordoba, that is not a rounding error.
In this guide, you will learn:
- Which platforms handle both Law 27,424 customer proposals and RenovAr tender bids
- How each tool manages net metering calculations with provincial variations
- Which software integrates design-to-proposal workflows (eliminating manual data transfer)
- Total cost of ownership for Argentine installer teams in USD and ARS
- Detailed comparisons of SurgePV, OpenSolar, Aurora Solar, Solargraf, and Energy Toolbase

Best Solar Proposal Software in Argentina (Detailed Reviews)
Pro Tip
For Argentine installers competing against 500+ registered firms, proposal speed matters as much as proposal quality. An integrated design-to-proposal platform lets you turn around a Law 27,424 customer proposal in 2-3 hours instead of 6-8 hours with manual processes. In a competitive market, the first professional proposal on the table often wins the deal.
SurgePV — Best Design-to-Proposal Platform for Both Market Tracks
Best For: Dual-market EPCs (RenovAr + Law 27,424), Law 27,424 residential and C&I installers, RenovAr tender preparation teams, multi-province solar sales professionals
Pricing: $1,899/year (3 users)
SurgePV is the only cloud-based platform that integrates complete design workflows with professional proposal generation for both Law 27,424 distributed generation customer proposals and RenovAr tender bid preparation.
For Argentine installers and EPCs, that integration means no manual data transfer between a design tool and a proposal tool. You design the system, run the simulation, and generate a professional proposal in one workflow. The numbers flow directly from design to proposal without re-entry errors, which matters when your net metering calculations determine whether a customer signs or walks.
Key Proposal Features for Argentina
SurgePV’s solar proposals include accurate net metering financial modeling. Compensation calculations use wholesale market price (roughly 0.7x retail tariff), not the retail rate that generic US-focused tools assume. Provincial variation support handles the differences between Buenos Aires, Cordoba, and Mendoza regulations. A net metering proposal that is accurate for Cordoba may overstate returns for a Buenos Aires customer.
Customizable proposal templates let you adapt outputs for Argentine customers. While the interface runs in English, proposal content — financial projections, system specifications, savings calculations — can be customized for Spanish-language delivery.
3D visualizations, production estimates, and financial projections all come from the same design model. No exporting CSV files from one tool and importing into another.
For the utility-scale market, SurgePV prepares complete tender bid packages: 20-year PPA cash flow projections based on CAMMESA contract structures, bankable P50/P75/P90 summaries from the same simulation engine that powers the design workflow, and CAMMESA interconnection documentation with automated SLD generation — included in proposals, not created separately in AutoCAD.
The 70,000+ module database tracks local Argentine manufacturers, supporting the 30-40% local content requirement that RenovAr tenders mandate.
Every proposal runs on SurgePV’s production simulation at plus or minus 3% accuracy versus PVsyst. For a 100 kW commercial rooftop in Buenos Aires, that accuracy means a realistic 8-year payback promise rather than an optimistic 6-year projection that disappoints the customer.
The solar ROI calculator models Argentine-specific inputs: provincial electricity tariffs, net metering compensation rates, and loan financing scenarios.
Real-World Example
A mid-sized installer in Argentina was losing C&I bids because proposals took 2-3 days to produce. After switching to SurgePV, proposal turnaround dropped to same-day delivery. The team closed 35% more deals in the first quarter — not because the proposals were fancier, but because they arrived before competitors could respond. Speed wins contracts.

What Makes the Best Solar Proposal Software for Argentina
Three factors separate effective proposal software from generic tools in the Argentine market.
1. Law 27,424 Net Metering Accuracy
This is the biggest differentiator. Argentina’s net metering compensates at wholesale market price — roughly 0.7x retail tariff — not the retail rate that US-designed tools assume. Getting this wrong means overpromising savings to customers. In a market with 500+ competing installers, one inaccurate proposal damages your reputation across an entire city.
Provincial variations add complexity. Buenos Aires, Cordoba, and Mendoza each run different distributed generation programs with distinct compensation structures and interconnection processes. Proposal software must model these provincial differences, not apply a one-size-fits-all national rate.
2. Design-to-Proposal Integration
Manual data transfer between a design tool and a proposal tool introduces errors and wastes time. When you change a panel count in your design, the production estimate in your proposal should update automatically. When you re-run a shading analysis, the financial projections should adjust without re-entry.
Integrated platforms (SurgePV, OpenSolar, Aurora) handle this automatically. Proposal-only tools (Solargraf, Energy Toolbase) require you to export data from a separate design tool and import it manually, adding 1-2 hours per proposal and creating opportunities for errors that undermine customer trust.
3. Pricing Stability in a Peso-Volatile Market
With 100-150% annual inflation and the peso at approximately 850 ARS/USD, predictable software costs matter more in Argentina than almost anywhere else. Contact sales pricing (Aurora, Energy Toolbase) means your monthly bill can increase without warning. Transparent annual pricing (SurgePV, OpenSolar, Solargraf) lets you budget in USD and absorb peso volatility without subscription surprises.
The total cost matters too. Proposal-only tools require separate design software ($2,000-3,000/year additional), pushing 3-year TCO to $8,000-18,000 versus $5,700-7,500 for integrated platforms.

Frequently Asked Questions
What is the best solar proposal software for Argentina?
SurgePV is the best all-in-one solar software for Argentina, combining Law 27,424 net metering customer proposals (with provincial variations for Buenos Aires, Cordoba, Mendoza) and RenovAr tender bid preparation (20-year PPAs, CAMMESA documentation) in one integrated design-to-proposal platform. For Law 27,424-only residential installers on a budget, OpenSolar (approximately $2,500/year) is an affordable alternative. For native Spanish interface, Solargraf (approximately $2,000/year) fills that gap but requires separate design software.
What software supports Law 27,424 net metering proposals?
SurgePV, OpenSolar, and Aurora Solar support Law 27,424 net metering proposals. SurgePV provides the most accurate provincial variation support, modeling different compensation rates and interconnection processes for Buenos Aires, Cordoba, and Mendoza. OpenSolar offers basic net metering calculations at lower cost. Aurora provides net metering proposals with strong visuals but limited Argentine customization. Solargraf and Energy Toolbase have minimal Law 27,424 support.
Can proposal software handle RenovAr tender bids?
SurgePV is the only proposal platform that supports complete RenovAr tender bid preparation — including 20-year PPA financial modeling, CAMMESA interconnection documentation with automated SLD generation, bankable P50/P90 summaries, and 30-40% local content tracking. OpenSolar, Aurora, Solargraf, and Energy Toolbase are designed for residential and commercial customer proposals, not utility-scale tender packages.
Is Spanish language support available in proposal software?
Solargraf offers the only native Spanish language interface among the five platforms evaluated. SurgePV and OpenSolar provide Spanish-customizable proposal outputs — the interface runs in English, but customer-facing proposal content (financial projections, system specs, savings calculations) can be customized for Spanish delivery. Aurora Solar has limited Spanish localization. Energy Toolbase has no Spanish support. For the 90% of Law 27,424 residential customers who expect Spanish proposals, customizable outputs from SurgePV or OpenSolar are sufficient for most use cases.
How does peso volatility affect proposal software costs?
Peso volatility (approximately 850 ARS/USD, compared to 140 ARS/USD in 2020) makes USD-priced software increasingly expensive in local terms. SurgePV at $1,899/year equals approximately 1.6M ARS with integrated design (no separate tools needed). OpenSolar at approximately $2,500/year equals approximately 2.1M ARS. Aurora at $4,860-9,324/year (3 users) equals approximately 4.1-7.9M ARS. Transparent fixed pricing matters more than ever in a high-inflation environment.
Can I use OpenSolar for RenovAr tenders?
No. OpenSolar is designed for residential and small commercial solar proposals under Law 27,424, not utility-scale tender preparation. RenovAr tenders (10-100 MW) require utility-scale design with tracker optimization, automated SLD generation for CAMMESA interconnection, bankable P50/P90 simulations for international lenders, 20-year PPA cash flow modeling, and 30-40% local content compliance documentation. None of these are available in OpenSolar.
How long does it take to create a Law 27,424 proposal?
With integrated design-to-proposal platforms: SurgePV takes 2-3 hours for a complete 100 kW commercial proposal (design through financial projections). OpenSolar takes 2-3 hours for residential proposals. Aurora takes 3-4 hours. With proposal-only tools requiring separate design: Solargraf takes 4-5 hours (manual data entry from separate design tool). Manual process with Excel and PowerPoint takes 6-8 hours. The 1-2 hour advantage of integrated platforms compounds across 50+ proposals per year.
What CRM integrations work for Argentine installer sales?
Aurora Solar offers the strongest CRM integrations with native Salesforce and HubSpot connectors — useful for larger Law 27,424 installer operations managing high lead volumes. OpenSolar provides basic CRM integration suitable for mid-size installers. SurgePV offers API integration for custom connections. For most Argentine installers handling 3-10 proposals per week, native CRM integration is a nice-to-have rather than a necessity.
