Best Solar Proposal Software Canada: 2026 Guide

Canada does not have a national solar proposal. It has ten of them. Export credit runs from $0.04390 per kWh under Manitoba net billing to full retail near $0.145 in Ontario, a spread of more than three times on identical hardware. Settlement periods range from monthly in Alberta to a 24 month reset in Quebec. Capacity caps run from 100 kW to 5 MW. On top of that sits a federal Clean Technology ITC that pays businesses 30% refundable and pays homeowners nothing, plus six live provincial programs and two that closed recently and still appear in circulating templates. This guide compares the platforms Canadian installers should shortlist, judged on whether they model the province rather than the country.

Short version. The best solar proposal software for Canadian installers in 2026 is SurgePV, because it models the customer’s actual provincial net metering framework, applies the federal Clean Technology ITC correctly to business buyers only, carries the live provincial rebate programs, and generates the document from the same engineering record. OpenSolar suits simple residential on cost. Aurora and Solargraf are US-structured and need manual handling of Canadian specifics.

Canadian solar is a smaller market than the US by volume but has larger average system sizes and a bigger share of commercial and agricultural work. That mix favours proposal tools that handle business tax treatment properly rather than residential-only platforms. For the design-side comparison see our best solar design software Canada guide, and the global solar proposal software ranking for the category without the Canadian lens.

The Provincial Problem, In One Table

The settlement period compounds it. Alberta settles monthly, so summer surplus cannot offset winter consumption at all. Quebec runs a 24 month reset, which is unusually generous and allows meaningful banking. Saskatchewan credits are non-expiring. A proposal that shows an annual net figure without stating the settlement basis is hiding whether the surplus actually carries.

SurgePV’s Canada compliance library and the interconnection guide carry the current provincial detail.

The Incentive Stack, And The Two Closed Programs

The federal Clean Technology Investment Tax Credit is the anchor for commercial and agricultural work: 30% refundable on capital cost through 31 December 2033. Refundable is the important word. It pays out even where the business has no tax liability in the year, which materially changes the cashflow case for smaller operators and farms. It does not apply to homeowners.

Two programs are closed and still circulate. The Canada Greener Homes Grant closed on 31 March 2024. The associated loan closed on 1 October 2025. Any proposal template still listing either is promising money that does not exist, and in a market where homeowners research heavily, that is a credibility problem as much as an arithmetic one. SurgePV’s federal incentives guide tracks what is live.

Quebec’s $1,000 per kW grant deserves specific attention. Launched in March 2026, it is currently the most generous per-kW residential program in the country and transforms residential economics in the province. A tool that cannot model it understates the return exactly where the return is strongest.

The Six Platforms Canadian Installers Should Evaluate

1. SurgePV, the integrated pick

Provincial net metering libraries, Clean Technology ITC with correct business-only application, live provincial rebate programs, SCC certification filtering, CSA C22.1 checks, 8,760-hour module-level shading, bankable P50, P75, P90, and white-label proposals with e-signature. $1,299 to $1,899 per user per year.

2. Aurora Solar

Deep residential design and a strong customer-facing document, built around US utility structures. No provincial libraries, no Clean Tech ITC, no SCC filtering. Sales Mode is a separate purchase. See our Aurora Solar alternative comparison.

3. OpenSolar

Free entry tier, workable for simple Canadian residential. Simplified shading is a real constraint at Canadian winter sun angles, and provincial rules are manual. Our OpenSolar alternative breakdown covers where free stops paying.

4. Solargraf

Clean residential documents with solid e-signature, Enphase-owned. Sits downstream of a design tool. Canadian incentives handled by manual line item. More in our Solargraf alternative review.

5. Enact Solar

Reasonable on financing presentation for residential. Smaller Canadian presence and partial incentive coverage. See our Enact Solar alternative review.

6. Spreadsheet plus a design tool

Common in smaller Canadian operations. The main source of closed-program lines and stale provincial rates in circulating quotes.

Canada Solar Proposal Software Comparison

Worked Example: 60 kW Commercial Rooftop, Ontario Versus Alberta

An illustrative calculation, not a specific customer project. Inputs: 60 kW DC, 1,150 kWh per kW specific yield, 69,000 kWh generation, 44,000 kWh on-site consumption, installed cost $105,000.

The interesting line is self-consumption. Alberta’s monthly settlement means summer surplus cannot offset winter draw, so a larger share of generation leaves as export even though total output is identical. Where a province settles on a longer cycle, the same array behaves as though more of its output were consumed on site. That effect is invisible to any tool working from annual totals, and it is the reason two provinces with similar headline rates can still produce different answers.

Who Should Choose What

• Choose SurgePV if you work across provinces, handle commercial or agricultural alongside residential, or run projects in both Canada and the US.
• Choose Aurora if you are Ontario residential at retail-rate net metering and comfortable handling Canadian specifics manually.
• Choose OpenSolar for simple residential where entry cost is decisive.
• Choose Solargraf if you already own a design tool and want a faster customer document.
• Retire the spreadsheet if it still lists the Greener Homes Grant, which closed in March 2024.

After signing, pipeline and follow-up move to a CRM. QuickEstimate takes the handoff from SurgePV by API.

The Bottom Line

Canadian proposal accuracy is a provincial question wearing a national costume. The federal layer is simple. Everything that decides the customer’s return sits below it.

• Name the province and the settlement period in every quote. Export rate alone does not describe the economics. Monthly settlement in Alberta and a 24 month reset in Quebec produce different outcomes at similar rates.
• Audit your template for closed programs. Greener Homes Grant closed March 2024, the loan closed October 2025, and both still appear in quotes in circulation.
