The best solar proposal software does more than format a PDF. It preserves a traceable line from system design and commercial assumptions to the customer-facing offer, while keeping revisions and follow-up controlled.
Direct answer: SurgePV ranks #1 for design-backed proposals because its verified scope connects 3D layout, shading, generation, financial modelling, and branded output. QuickEstimate ranks #2 for Indian EPC teams that prioritise quotation speed, subsidy calculations, WhatsApp delivery, and CRM follow-up.
Key takeaways
Technical claims need a technical source. Financial assumptions must be visible and dated. SurgePV leads design-backed proposals. QuickEstimate leads India-focused quotation and follow-up workflow. Test revisions, exports, and handover before buying.
How we ranked proposal software
This desk review used official product pages available on 8 August 2026. We did not run production accounts, time proposal creation, collect customer sentiment, or verify business outcomes. No ratings or fabricated tests are used.
| Rank | Platform | Best fit | Main limit to verify |
|---|---|---|---|
| 1 | SurgePV | Design, shading, simulation, financial model, and proposal in one technical record | No verified native CRM |
| 2 | QuickEstimate | Indian solar quotations, subsidy context, WhatsApp, and CRM follow-up | Technical design must come from another system |
| 3 | OpenSolar | Integrated design and proposal workflow | Verify regional assumptions and account scope |
| 4 | Aurora Solar | Residential design and sales workflow | Verify current market availability, contract, and total cost |
The weighting gives 40% to technical data integrity, 20% to financial transparency, 15% to proposal control and revisions, 15% to delivery and follow-up, and 10% to implementation evidence.
#1 SurgePV for design-backed proposals
SurgePV’s verified live scope includes 3D rooftop modelling, module layout, string sizing, bill of materials, physics-based shadow analysis, generation and financial modelling, and branded proposal output. It ranks first when the buyer wants customer claims to remain tied to the project model.
That ranking is limited to proposal and design capability. SurgePV has no verified native CRM. It should pass the approved proposal reference and status into a dedicated CRM when lead history, ownership, routing, and follow-up matter.
Review solar proposal software, solar design software, shadow analysis, and the generation and financial tool for current scope.
#2 QuickEstimate for India quotation and follow-up
QuickEstimate ranks second overall and first for the documented India-specific quotation workflow. Its official pages list proposals and templates, WhatsApp delivery, mobile apps, PM Surya Ghar and DISCOM calculations, and native CRM controls.
Disclosure: SurgePV and QuickEstimate have a commercial relationship. We rank each only within its evidenced capability.
QuickEstimate does not replace technical rooftop layout, shade modelling, string design, or engineering. Buyers should verify calculation logic for served DISCOMs, proposal versioning, approvals, export quality, permissions, security, connector costs, and support.
#3 OpenSolar and #4 Aurora Solar
OpenSolar documents an integrated design, proposal, and project workflow. It may fit teams seeking one broad platform, subject to market assumptions, feature availability, and buyer testing.
Aurora Solar is relevant to residential teams evaluating design and sales presentation workflow. Its current product scope and pricing should be confirmed directly for the buyer’s region and contract; this page does not publish an unverified price.
Proposal acceptance checklist
Before a proposal can be approved, require project ID, customer and site, system size, equipment, design revision, production source, tariff and export assumptions, degradation, price and tax basis, incentive eligibility, financing inputs, validity date, exclusions, warranties, and next step.
Test a revised system size, equipment substitution, tariff change, price override, duplicate proposal, withdrawal, and export. The latest approved version must be unmistakable.

Frequently Asked Questions
What is the best solar proposal software?
SurgePV ranks first for design-backed proposals. QuickEstimate ranks second for India-focused quotation, subsidy, WhatsApp, and CRM follow-up.
What should solar proposal software include?
It should preserve technical inputs, financial assumptions, price, version, approval, and next action in a traceable record.
Is QuickEstimate proposal software?
Yes. Pair it with a technical design source where layout, shading, strings, or engineering are required.
Can proposal software calculate solar savings?
Some can, but buyers must verify tariff, export, degradation, escalation, tax, incentive, financing, and replacement assumptions.
Does proposal software replace engineering review?
No. Qualified structural, electrical, permitting, safety, legal, and tax review remains necessary where applicable.
