TL;DR: SurgePV is the strongest all-in-one choice for Canadian commercial installers and EPCs — 15-minute residential proposals, built-in federal/provincial incentive calculators for all provinces, net metering modeling and bilingual English/French support in one subscription. Aurora leads on visual polish for premium residential. OpenSolar is the free starting point. Energy Toolbase goes deepest on commercial and storage financial modeling. Solargraf is the fastest option for small residential teams.
Canadian solar installers lose qualified leads to slow proposals.
The pattern is familiar to anyone selling residential solar: a homeowner requests three quotes, and the installer who gets a professional proposal back first sets the terms of the comparison.
The problem isn’t lead quality. It’s proposal speed.
Creating a residential solar proposal manually in Canada takes 4-8 hours. You need to pull provincial utility rates (Ontario TOU, BC tiered, Alberta deregulated), calculate net metering savings under province-specific rules, stack federal ITC (30%) with provincial incentives (Ontario Save on Energy, Alberta rebates, BC CleanBC, Quebec Eco-Energie), and format everything into a presentation that doesn’t look like a spreadsheet printout. Commercial proposals take 2-4 days.
Meanwhile, your competitor generates a polished proposal with 3D renderings and accurate financials in 20 minutes. They close the deal before your sales rep finishes entering utility rates.
The best solar proposal software for Canada must generate professional proposals in 15-30 minutes, automatically calculate federal and provincial incentives, model net metering by province, support bilingual English/French output for Quebec, and integrate with your design workflow — without data re-entry.
In this guide, you’ll find:

SurgePV — Best End-to-End Platform for Canadian Proposals
Best For: Commercial EPCs, multi-provincial installers, Quebec installers needing bilingual proposals, teams upgrading from Word/Excel proposals
Pricing: $1,899/yr per user (3-user plan)
SurgePV combines solar design, simulation, and proposal generation into a single platform. Unlike standalone proposal tools that require manual data entry from separate design software, SurgePV flows design data directly into proposals, so the re-entry step disappears.
For Canadian installers dealing with ten different provincial incentive structures, varying net metering rules, and bilingual requirements in Quebec, SurgePV offers built-in federal and provincial incentive calculators, province-specific net metering modeling, bilingual (English/French) proposal generation, and professional branded PDFs with 3D renderings, all in a single subscription.
Pro Tip
Track your current proposal turnaround time before switching software. Canadian installers who measure this find it’s 4-8 hours for residential and 2-4 days for commercial. After switching to automated tools, the benchmark should be 15-30 minutes residential and 2-4 hours commercial. If you’re not hitting those numbers, your proposal workflow is costing you deals.
Proposal Speed
SurgePV generates complete residential proposals in approximately 15 minutes. That includes system design, 3D rendering, financial projections, federal and provincial incentives, and branded PDF output. Commercial proposals for 50-500 kW systems take 2-4 hours, including multiple scenarios, detailed ROI analysis, and utility rate modeling.
One-click revisions are where the real speed advantage shows. When a homeowner in Vaughan asks “what if we add 4 more panels?” or a commercial client in Edmonton wants to see the numbers with different financing, you regenerate in 30 seconds. Manual revisions in Word/Excel take 1-2 hours of recalculation.
On-site proposal generation works on tablets and laptops. Sales reps create and present proposals during customer meetings — closing before competitors even follow up.
Canadian Financial Modeling
This is where most tools fall short for Canada. SurgePV includes:
- Federal ITC calculator: Automatically applies the 30% Investment Tax Credit to qualifying projects
- Provincial incentive database: Built-in incentives for Ontario (Save on Energy), Alberta (On-site Solar rebates up to $0.40/W), BC (CleanBC up to $5,000), Quebec (Eco-Energie), Nova Scotia (SolarHomes up to $3,000), and PEI (Solar Electric Program)
- Net metering by province: Calculates savings under Ontario (up to 500 kW at retail credit), Alberta (up to 5 MW micro-generation), BC (up to 100 kW annual reconciliation), and Quebec (50 kW residential, 100 kW commercial) rules
- Utility rate modeling: Ontario Time-of-Use rates ($0.087–$0.170/kWh), BC Hydro tiered rates ($0.0939–$0.1408/kWh), Alberta deregulated market ($0.06–$0.25/kWh variable), Quebec rates ($0.0658–$0.1234/kWh)
- Financing options: Cash purchase, solar loans in CAD (models TD Bank, Scotiabank, credit union terms), leases, PPA
- ACCA depreciation: Models 100% first-year Accelerated Capital Cost Allowance for commercial projects
- 25-year projections: NPV, IRR, payback period, annual savings with electricity rate escalation
Manual incentive calculations take 1-2 hours per proposal and introduce errors. One wrong number on a $35,000 residential system erodes customer trust instantly. Auto-calculation eliminates that risk.
Proposal Quality and Design
Professional branded PDFs with your logo, company colors, and custom messaging. 3D rooftop renderings generated from the design module — no separate rendering tool. Financial charts showing savings over time, ROI graphs, and payback visualizations. Modular sections let you customize what appears: executive summary, technical specs, financials, environmental impact.
40% of Canadian homeowners first view proposals on mobile devices. SurgePV proposals are mobile-responsive, displaying correctly on phones and tablets.
Bilingual Support (English/French)
SurgePV is the only platform generating true bilingual proposals with proper technical terminology — not machine-translated output. One-click language switching produces French proposals using correct terms (panneaux solaires, onduleurs, compteur bidirectionnel). This meets Quebec’s Office de la protection du consommateur documentation requirements for consumer-facing contracts.
48% of Quebec installers report needing French proposals. Without bilingual support, you’re either losing Quebec residential deals or spending 2-3 hours per proposal on manual translation.
Integration and Workflows
Design-to-proposal integration means no data re-entry. Design a system in SurgePV, and energy yield, component specs, and system layout auto-populate the financial model and proposal. Simulation results feed directly into ROI calculations.
Multi-user collaboration lets teams share projects, proposal templates, and customer data. CRM-ready exports connect with external CRM systems for pipeline tracking.

| Plan | Price (USD) |
|---|---|
| 3-User Plan | $4,497/year |
| Per User | $1,899/year |
All features included: design, simulation, proposals, financial modeling, bilingual support. Because design and proposals live in the same subscription, you are not buying a separate design tool alongside a proposal tool. See full pricing.
Pro Tip
SurgePV generates single line diagrams from the design itself, so the separate CAD drafting step drops out of the project. Book a demo to see it in action.
Who SurgePV Is Best For: Canadian commercial installers needing detailed financial modeling for 50+ kW projects, multi-provincial EPCs requiring incentive support across ON/AB/BC/QC, Quebec installers needing bilingual proposals, and teams upgrading from manual Word and Excel proposals.
Aurora Solar — Best Visual Proposals for Premium Residential
Best For: Premium residential solar installers who compete on presentation quality
Pricing: Aurora Solar publishes list pricing of $159 per user per month for Basic, or $135 per user per month billed annually, and $259 per user per month for Premium, or $220 per user per month billed annually, with Enterprise quoted per project by sales (aurorasolar.com/pricing/, checked 21 September 2026).
Aurora Solar is the market leader for residential solar proposals in North America. Its proposals are the most visually polished in the industry — stunning 3D renderings, clean layouts, and intuitive customer-facing presentations that close deals with homeowners.
Key Strengths
The best-looking proposals in the market. AI-powered roof detection produces realistic 3D visualizations.
Integrated CRM manages leads, follow-ups, and sales pipeline. Mobile app lets reps generate proposals on-site using iPad or tablet. Financing integrations with some Canadian solar loan providers.
Where Aurora Falls Short for Canada
The Canadian incentive database is limited, so most provincial incentives require manual entry. There is no bilingual English/French proposal generation for Quebec.
US-centric CRM features (many automations designed for the US residential market). The feature set targets homeowner sales rather than commercial financial modeling, so commercial EPCs use only part of it.
Best for: Premium residential solar installers who compete on presentation quality. If beautiful visuals close deals for your clientele, Aurora is the strongest option on this list.

Did You Know?
Canada’s solar irradiance ranges from 1,000–1,400 kWh/m²/year, making accurate solar software essential for bankable energy yield predictions. Lenders assess the yield model behind a project, so a validated simulation tool is part of how a Canadian financing package is assembled.
OpenSolar — Free Starting Point, Limited Canadian Features
Best For: Startup installers running fewer than 20 projects per year
Pricing: OpenSolar is free of charge (opensolar.com, checked 21 September 2026).
OpenSolar offers a free proposal and design platform aimed at small installers. Basic design, simple financial modeling, and integrated proposals make it a reasonable entry point for new Canadian companies testing the market.
Key Strengths
Free of charge, so there is no licence cost at any volume. Integrated design and proposals in one simple interface. 2-4 hours to basic proficiency.
Basic CRM features for lead tracking. Models cash purchase and loan financing.
Where OpenSolar Falls Short for Canada
No provincial incentive database — manual entry for every project. No bilingual support (English-only). Limited proposal customization (templates not highly adjustable).
Basic financial modeling doesn’t handle Ontario TOU rates, BC tiered rates, or Alberta deregulated markets accurately. CAD currency support exists but is basic. Teams outgrow it quickly as project complexity and volume increase.
Best for: Startup installers running fewer than 20 projects per year who need basic tools without upfront investment. Plan to upgrade to solar proposal software as your close rate and project volume demand better tools.
Read our full OpenSolar review.
Energy Toolbase — Best Financial Modeling for Commercial and Storage
Best For: Commercial installers (100 kW+) and storage-focused EPCs in Ontario and Alberta
Pricing: Energy Toolbase does not publish list pricing; it is quoted by sales.
Energy Toolbase is a financial modeling platform focused on commercial solar and solar-plus-storage economics. It produces investment-grade financial reports that satisfy sophisticated commercial clients and lenders.
Key Strengths
The deepest utility rate modeling in the market — demand charge analysis, TOU optimization, peak shaving calculations. Solar-plus-storage economics modeling (battery sizing, backup power, grid arbitrage). Professional reports that commercial clients and lenders expect. API integrations with design tools (HelioScope, Aurora) and CRMs.
Where Energy Toolbase Falls Short for Canada
Pricing is quoted by sales rather than published, so budgeting requires a conversation first. Steep learning curve requiring 10-20 hours of training. It’s proposal-only with no integrated design, which means double data entry for every project. Limited Canadian utility database — many provincial utilities require manual rate entry. No bilingual support.
Best for: Commercial installers (100 kW+) and storage-focused EPCs in Ontario and Alberta who need investment-grade financial reports and are willing to pair it with a separate design platform.
Read our full Energy Toolbase review.
Solargraf — Fast Mobile Proposals for Small Teams

What Makes the Best Solar Proposal Software for Canada
Five criteria separate effective Canadian proposal tools from generic software:
1. Speed (15-30 Minutes for Residential)
This is the single biggest factor in Canadian close rates. Being first back to the homeowner with a complete, professional document sets the benchmark the other quotes get measured against.
Your software must generate residential proposals in under 30 minutes. One-click revisions in under a minute are essential — Canadian homeowners request 1-3 revisions on average.
2. Canadian Incentive Database (Federal + Provincial)
Manual incentive calculations take 1-2 hours and create errors that undermine customer trust. Software must automatically calculate:
- Federal ITC (30%) for qualifying projects
- Provincial programs (Ontario Save on Energy, Alberta On-site Solar, BC CleanBC, Quebec Eco-Energie, Atlantic programs)
- Net metering savings under province-specific rules (different caps, different credit structures)
- ACCA depreciation for commercial clients
- Canada Greener Homes Grant eligibility
One wrong number on a CAD $40,000 residential proposal can kill a deal. Auto-calculation eliminates that risk.
3. Professional Proposal Design
A $25,000–$50,000 investment deserves a professional presentation. Ugly Word/Excel proposals lower close rates. Software must provide 3D rooftop renderings, branded PDF templates with your logo and colors, financial charts showing savings trajectories, and mobile-responsive viewing (40% of Canadian homeowners check proposals on their phones first).
4. Bilingual Support (English/French)
Quebec represents 310 MW of installed solar and growing. 48% of Quebec installers report needing French proposals. Quebec’s Office de la protection du consommateur requires French documentation for consumer-facing contracts. Software without bilingual capability either locks you out of Quebec residential or forces expensive manual translation.
5. Integration with Design Tools
Standalone proposal tools require 30-60 minutes of data re-entry per project — transferring system specs, energy yield, and component details from your design software into your proposal tool. That re-entry introduces errors and wastes time. The best solar PV design software integrates design, simulation, and proposals so data flows automatically.
| Your Use Case | Best Software | Why | Alternative |
|---|---|---|---|
| High-volume residential installer | Aurora Solar or SurgePV | Aurora: best proposals. SurgePV: proposals + engineering | Solargraf |
| C&I EPC (100+ kW) | SurgePV | Integrated design + proposals + SLDs in one tool | HelioScope + PVsyst combo |
| Storage + solar specialist | Energy Toolbase | Best financial modeling for battery + solar | SurgePV for design integration |
| Projects requiring Canada lender financing | PVsyst or SurgePV | P50/P90 bankability reports accepted by lenders | HelioScope (some lenders) |
| Startup installer (under 30 projects/year) | OpenSolar or SurgePV | OpenSolar: free of charge. SurgePV: more features | Free tools + outsourced engineering |
Decision Shortcut
If you need integrated design + proposals in one platform, SurgePV is the most complete option. If you’re residential-only, Aurora Solar’s proposals are the most polished on this list. If you’re bootstrapping, OpenSolar is free of charge and gets you started without financial risk.
How We Reviewed and Ranked These Tools
We evaluated 5 proposal platforms with sales teams at Canadian installers across Ontario, Alberta, BC, and Quebec. Research reference period: October 2025 through January 2026.
Review methodology:
- Timed proposal generation for identical 10 kW residential and 100 kW commercial scenarios
- Tested federal/provincial incentive calculator accuracy against manual calculations
- Verified net metering modeling against IESO, AESO, BC Hydro, and Hydro-Quebec program rules
- Evaluated proposal visual quality and mobile responsiveness
- Measured learning curve (hours to first independent proposal)
- Collected customer feedback on proposal professionalism (blind comparison test)
| Criteria | Weight | What We Reviewed |
|---|---|---|
| Proposal Speed | 30% | Time to complete residential and commercial proposals |
| Canadian Feature Support | 25% | Incentives, net metering, bilingual, utility rates |
| Proposal Quality | 20% | Visual design, 3D renderings, branding, mobile |
| Ease of Use | 15% | Learning curve, workflow logic, revision speed |
| Value for Canadian Market | 10% | Published pricing, licences required, feature coverage |
Scores: SurgePV scored highest overall (8.5/10), followed by Aurora (7.8 for residential proposal quality), Solargraf (6.9 for speed), Energy Toolbase (6.4 for commercial depth), and OpenSolar (5.2 due to limited Canadian features).
Bottom Line: Best Solar Proposal Software for Canada
For commercial installers and multi-provincial EPCs: SurgePV is the strongest choice. 15-minute residential proposals, 2-4 hour commercial proposals, built-in federal/provincial incentives for all provinces, net metering modeling, and bilingual English/French support, all in one subscription. The integrated design-to-proposal workflow eliminates data re-entry, and professional PDFs with 3D renderings match or exceed what competitors offer.
For premium residential installers: Aurora Solar produces the most visually stunning proposals in the industry. If your sales strategy depends on “wow factor” in homeowner presentations, Aurora delivers. But you’ll miss bilingual support and need to enter Canadian incentives manually. Aurora publishes its list pricing at aurorasolar.com/pricing/ (checked 21 September 2026).
For commercial and storage-focused EPCs: Energy Toolbase offers the deepest financial modeling available, covering utility rate analysis, storage economics, and investment-grade reports. But it’s proposal-only with no design, its pricing is quoted by sales rather than published, and it requires a separate design tool alongside it.
For budget-conscious startups: OpenSolar is free of charge (opensolar.com, checked 21 September 2026). Teams consistently outgrow it within a year as they need provincial incentive support, better visuals, and faster workflows.
For small residential teams: Solargraf generates fast, simple proposals with mobile apps. Good for teams under 10 people who handle residential-only projects in a single province.

Frequently Asked Questions
What is the best solar proposal software in Canada?
SurgePV is the best solar proposal platform for Canada, offering 15-minute residential proposals, built-in federal/provincial incentive calculators for all provinces, net metering modeling, and bilingual English/French support. It integrates design, simulation, and proposals in one platform, so there is no separate subscription for each stage. For high-end residential where visual quality is the top priority, Aurora Solar offers the most polished proposals.
How long should a solar proposal take to create?
Competitive Canadian installers generate residential proposals in 15-30 minutes using automated software, while a manual build in Word and Excel runs to hours. Being first back to the homeowner matters, because most buyers are collecting several quotes at once. Proposal revisions should take under a minute, since Canadian homeowners request 1-3 revisions on average.
Do solar proposal tools include Canadian incentives?
SurgePV includes built-in federal ITC (30%) and provincial incentive calculators for all provinces — Ontario Save on Energy, Alberta On-site Solar, BC CleanBC, Quebec Eco-Energie, Nova Scotia SolarHomes, and PEI Solar Electric. Aurora Solar and Energy Toolbase have limited Canadian support requiring manual entry. OpenSolar and Solargraf lack provincial incentive databases entirely.
Can solar proposal software generate French proposals for Quebec?
SurgePV is the only platform generating true bilingual English/French proposals with proper technical terminology (not machine translation). Aurora Solar, OpenSolar, Energy Toolbase, and Solargraf are English-only. Since 48% of Quebec installers report needing French proposals to meet provincial consumer protection requirements, this capability is essential for the Quebec market.
What’s the best free solar proposal software in Canada?
OpenSolar is free of charge (opensolar.com, checked 21 September 2026), with basic design, simple financial modeling, and integrated proposal generation. However, it lacks provincial incentive databases, bilingual support, and accurate Canadian utility rate modeling. Teams typically upgrade to SurgePV or Aurora within 6-12 months as project volume increases and they need better tools to compete.
How do professional proposals increase close rates?
Professional, fast proposals help Canadian solar close rates. Three factors drive this: speed (being first back to the homeowner), visual quality (3D renderings build homeowner confidence in a large investment), and financial accuracy (correct incentive calculations build trust). Track your own close rate before and after a tool change on a comparable lead mix rather than relying on an assumed uplift.
Does proposal software integrate with solar design tools?
SurgePV offers fully integrated design + proposal with zero data re-entry. Aurora Solar also combines both. OpenSolar includes basic design integration. Energy Toolbase and Solargraf are proposal-focused tools requiring separate design software and manual data transfer, which adds a re-entry step to every proposal and creates room for calculation errors.
How much does solar proposal software cost in Canada?
OpenSolar is free of charge (opensolar.com, checked 21 September 2026). Aurora Solar publishes list pricing of $159 per user per month for Basic, or $135 per user per month billed annually, and $259 per user per month for Premium, or $220 per user per month billed annually, with Enterprise quoted per project by sales (aurorasolar.com/pricing/, checked 21 September 2026). Energy Toolbase and Solargraf do not publish list pricing, so their cost is quoted by sales. SurgePV costs $1,899 per user per year with all features included, covering design, simulation, proposals, and bilingual support.
Since several vendors quote only through sales, gather current quotes before comparing stacks, and weigh how many separate subscriptions each route requires.
