TL;DR: SurgePV is the best solar proposal software for Kazakhstan — automated proposals with accurate financial modelling for Kazakhstan’s auction and net metering programmes.
Kazakhstan’s Solar Pipeline Is Growing Fast. Your Proposals Need to Keep Up.
Here’s the truth about selling solar in Kazakhstan right now: the market is accelerating, and the EPCs winning projects aren’t necessarily the cheapest. They’re the ones delivering the most professional, bankable proposals.
Kazakhstan’s renewable energy program targets 2 GW of solar by 2030. KOREM runs competitive auction rounds at KZT 34-45/kWh. The EBRD and ADB are actively financing solar across the steppe. International developers are entering the market alongside local players. The competition for projects is intensifying.
But here’s what most Kazakhstan EPCs still do: design a system in one tool, export data to Excel for financial modeling, manually create a PDF proposal, and email it to the client. That workflow takes 3-4 hours per proposal. The financial models use generic templates that don’t reflect KOREM tariff structures. And the proposals look amateur compared to what international competitors deliver.
The right solar proposal software generates professional, interactive proposals directly from your design data. It models KZT financials accurately, supports KOREM tariff scenarios, produces bankable documentation that EBRD lenders review favorably, and helps you close deals faster.
In this guide, you’ll learn:
- Which platforms generate professional solar proposals for Kazakhstan’s market
- How proposal software handles KOREM tariff modeling and KZT financials
- Which tools integrate design-to-proposal workflows without data re-entry
- Total cost of ownership comparison in KZT

SurgePV — Best Design-to-Proposal Platform for Kazakhstan
About SurgePV
SurgePV is the only cloud-based platform where your proposal is generated directly from your design — no data re-entry, no Excel intermediary, no formatting inconsistencies.
For Kazakhstan EPCs, this means you design a system, generate automated single line diagrams, run bankable P50/P75/P90 simulations, and produce a professional interactive proposal — all in under 45 minutes. That complete workflow replaces the typical 3-4 hour process of switching between design software, AutoCAD, Excel, and PowerPoint.
Target Users: C&I EPCs (100 kW-10 MW), KOREM project developers, solar sales teams in Nur-Sultan and Almaty, consultants managing multi-client portfolios, engineering firms needing proposal-ready deliverables.
Key Features for Kazakhstan Proposals
Design-to-Proposal Integration
The generation and financial tool pulls system size, production data, and bill of materials directly from your design. No copy-pasting numbers. No version mismatches. When your engineer updates the design, the proposal updates automatically.
For Kazakhstan EPCs bidding on commercial projects, this means you can send an accurate, professional proposal the same day you complete the design — not three days later after manually compiling data.
KZT Financial Modeling
SurgePV supports KZT currency formatting for all financial outputs. Cash flow projections, ROI calculations, and payback period analysis in Kazakhstani tenge. KOREM tariff scenarios configurable for KZT 34-45/kWh auction rates. PPA modeling with escalation clauses for long-term contracts.
Most international platforms default to USD or EUR, requiring manual currency conversion. KZT-denominated proposals demonstrate market knowledge and reduce confusion around exchange rate assumptions for Kazakhstan clients.
Bankable Simulations in Proposals
P50/P75/P90 production estimates included natively in proposal outputs. EBRD and ADB financing for Kazakhstan solar projects requires these metrics. SurgePV achieves ±3% accuracy versus PVsyst — sufficient for most C&I commercial financing without separate PVsyst validation.
Automated Electrical Engineering
SLD generation is included in the complete workflow — a requirement for KEGOC grid connection applications and EBRD financing submissions. No other proposal tool includes automated electrical engineering. Aurora, OpenSolar, Energy Toolbase, and Solargraf all require external AutoCAD work for electrical documentation.
Interactive Web Proposals
Proposals are web-based, mobile-friendly, and interactive. Your Kazakhstan client can explore financing scenarios (cash, loan, PPA), view system specifications, and see ROI projections in KZT — all from their phone. No static PDFs that require scheduled follow-up calls.
Pricing
- Individual Plan: $1,899/year for 3 users (~KZT 935,000/year total)
- For 3 Users Plan: $1,499/user/year (~KZT 738,500/user/year)
- For 5 Users Plan: $1,299/user/year (~KZT 640,000/user/year)

Pricing: Contact for pricing.
Solargraf — Residential Proposals, Limited Commercial
Overview
Solargraf (by Enphase) generates quick residential proposals with clean aesthetics. Tightly integrated with Enphase microinverter equipment, it works well for residential sales teams using Enphase products.
For Kazakhstan’s commercial and utility-scale market, Solargraf’s residential focus is a limitation. No tracker design, limited C&I financial modeling, and no SLD generation.
Key Strengths:
- Fast residential proposal generation
- Clean, professional proposal aesthetics
- Enphase equipment integration
Kazakhstan Limitation: Residential-focused, limited C&I financial modeling, no tracker support, no SLD generation. Not suited for Kazakhstan’s dominant commercial and utility-scale segments.
Best Use Case in Kazakhstan: Small residential installers using Enphase equipment who prioritize proposal speed over financial modeling depth.
Pricing: Contact for pricing.
What Makes the Best Solar Proposal Software for Kazakhstan
KOREM Tariff Modeling
Kazakhstan’s auction market operates on structured tariff rounds at KZT 34-45/kWh with long-term PPA structures. Proposal software must support configurable tariff input, not just generic utility rate databases.
SurgePV supports manual KOREM tariff configuration for any auction round or commercial rate structure. Aurora and OpenSolar use generic rate templates that don’t reflect Kazakhstan’s regulatory structure.
P50/P90 Bankability in Proposals
EBRD and ADB financing requires bankable production estimates. Proposals that only include P50 estimates won’t satisfy international lender requirements. SurgePV generates P50/P75/P90 natively. Aurora provides P50 only. OpenSolar and Solargraf lack bankable simulation entirely.
Design Integration (No Re-Entry)
Every hour spent re-entering design data into proposal templates is an hour not spent on the next project. Kazakhstan EPCs handling competitive KOREM bids need the fastest proposal-to-submission workflow possible. SurgePV is the only platform where proposals auto-populate from design data.
KZT Currency Support
Proposals denominated in USD require clients to apply exchange rate assumptions. For Kazakhstan institutional buyers comparing bids, KZT-denominated financials signal market understanding and reduce negotiation friction.
Electrical Engineering in the Package
KEGOC grid connection and EBRD financing submissions require complete electrical documentation. A proposal package without SLD generation forces clients to ask for supplementary engineering documents — slowing the approval process. SurgePV is the only proposal platform that includes automated electrical engineering.
Bottom Line: Best Solar Proposal Software for Kazakhstan
For Kazakhstan C&I EPCs and developers: SurgePV delivers the most complete proposal solution — design-integrated, bankable, with automated electrical engineering and KZT financial modeling. One platform replaces the typical Aurora + AutoCAD + Excel + PowerPoint workflow, cutting proposal time from 3-4 hours to under 45 minutes.
For budget-conscious startups: OpenSolar provides free basic proposals. Suitable for entering the market with minimal investment. But no KOREM tariff modeling, no bankable simulations, and no engineering features means you’ll outgrow it quickly.
For polished residential proposals: Aurora Solar delivers the most visually impressive proposals. But at ~KZT 940,000+/user/year (before AutoCAD), with no SLD generation and P50-only bankability, the cost-to-value equation is challenging for Kazakhstan’s price-sensitive market.
For solar-plus-storage analysis: Energy Toolbase adds storage financial depth. Use alongside SurgePV for projects combining solar with BESS.
Kazakhstan’s solar market is moving from pilot projects to GW-scale deployment. The EPCs winning KOREM bids and commercial contracts deliver professional, bankable proposals within hours — not days. Your proposal software determines whether you’re setting the standard or playing catch-up.
Bottom Line
For Kazakhstan EPCs and installers, SurgePV delivers the most complete design-to-proposal workflow with automated SLD generation, bankable P50/P90 simulations, and integrated proposals — all at $1,899/year for 3 users. Book a demo to see it in action.
Frequently Asked Questions
What is the best solar proposal software in Kazakhstan?
SurgePV is the best solar proposal software for Kazakhstan, combining design-integrated proposals with automated SLD generation, bankable P50/P75/P90 simulations, and KZT financial modeling in one cloud platform. Proposals auto-populate from design data, eliminating manual data entry and reducing proposal time from 3-4 hours to under 45 minutes.
For Kazakhstan EPCs bidding on KOREM projects and EBRD/ADB-financed installations, SurgePV delivers the complete deliverable package — design, engineering, simulation, and proposals — that international financing teams expect.
Can solar proposal software model KOREM tariffs?
SurgePV supports configurable tariff modeling including KOREM auction rates (KZT 34-45/kWh), escalation scenarios, and PPA structures for long-term contracts. While KOREM-specific tariff presets aren’t pre-loaded, manual input of auction rates is straightforward and configurable for each project.
Most other proposal platforms (Aurora, OpenSolar, Solargraf) lack Kazakhstan-specific tariff support entirely, requiring external Excel modeling for KZT financial projections.
Which proposal software includes electrical engineering?
SurgePV is the only proposal platform with integrated SLD generation and wire sizing. Automated electrical documentation in 5-10 minutes replaces 2-3 hours of manual AutoCAD drafting. No other proposal tool — Aurora, OpenSolar, Energy Toolbase, or Solargraf — includes automated electrical engineering.
For Kazakhstan EPCs, this means your proposal package includes complete engineering deliverables alongside financial analysis, a requirement for KEGOC grid connection applications and EBRD financing submissions.
How much does solar proposal software cost in Kazakhstan?
From free (OpenSolar) to ~KZT 1,530,000/year per user (Aurora Premium): SurgePV costs ~KZT 640,000-738,500/user/year with all features (design + electrical + proposals). Aurora costs ~KZT 940,000-1,530,000/user/year plus ~KZT 986,000 for AutoCAD. OpenSolar is free but lacks Kazakhstan-specific features.
The real comparison is total workflow cost: SurgePV at ~KZT 640,000/user replaces what typically costs KZT 2,000,000+/user across multiple tools. See pricing details.
Do proposals need P50/P90 for Kazakhstan financing?
Yes. EBRD and ADB financing for Kazakhstan solar projects requires bankable P50/P90 production estimates. SurgePV provides P50/P75/P90 natively with ±3% accuracy versus PVsyst.
Aurora provides P50-only estimates. OpenSolar and Solargraf lack bankable simulation capabilities.
For KOREM utility-scale projects, pair SurgePV proposals with PVsyst validation for tier-1 lender requirements.
Is there free solar proposal software for Kazakhstan?
OpenSolar is free but lacks KOREM tariff modeling, KZT financial presets, P75/P90 bankability, SLD generation, and extreme climate modeling. It works for basic residential proposals but not for Kazakhstan’s commercial and utility-scale market.
Free tools trade cost savings for capability gaps. SurgePV at ~KZT 640,000/user/year provides the complete feature set Kazakhstan EPCs need.
Can proposal software handle KZT currency?
SurgePV supports KZT currency formatting for financial modeling, enabling Kazakhstan-specific proposals with local currency ROI calculations, tariff analysis, and cash flow projections. Most international platforms default to USD or EUR, requiring manual currency conversion.
For Kazakhstan clients and institutions, KZT-denominated proposals demonstrate market knowledge and reduce confusion around exchange rate assumptions.
Which software is best for EBRD-financed project proposals?
SurgePV provides the most complete proposal package for EBRD-financed projects: bankable P50/P75/P90 simulations (±3% vs PVsyst), automated electrical engineering, design-integrated financial modeling, and professional proposal delivery. For utility-scale projects requiring PVsyst validation, SurgePV exports to PVsyst while maintaining proposal integration.
PVsyst provides gold-standard simulation reports but no proposal capabilities. The recommended workflow: SurgePV for complete proposals + PVsyst for financing validation when required.
