Best Solar Proposal Software in Greece (2026): Top 5 Tools Compared

TL;DR: SurgePV is the best solar proposal software for Greece, combining Greek net metering modeling (Law 4414/2016), energy community support (Law 4513/2018), Fotovoltaika subsidy integration, and EUR pricing — all connected to a full design workflow. Aurora Solar offers beautiful proposal templates but lacks Greek market integration. Energy Toolbase excels at financials but requires a separate design tool.

Greek solar proposals are broken. Not the projects — the proposals themselves. Your residential customer in Athens expects Greek-language documentation with Fotovoltaika subsidy calculations.

Your commercial client in Thessaloniki needs net-metering payback projections under Law 4414/2016. That energy community on Crete? Member allocation models for virtual net-metering under Law 4513/2018.

Three different proposal types. Three different regulatory frameworks.

Here is the problem. Most solar proposal software was built for the US market. US net-metering rules. USD pricing. English-only templates. That leaves Greek solar installers patching together Excel spreadsheets and generic PDF templates — and losing deals to competitors who show up with professional, Greek-specific proposals on day one.

We tested five proposal platforms specifically for Greek market needs: net-metering compliance, energy community modeling, Fotovoltaika subsidies, EUR pricing, and Greek language support.

Best Solar Proposal Software in Greece

SurgePV — Best End-to-End Solar Proposal Platform for Greece

Best For: Greek EPCs and installers serving commercial net-metering, residential Fotovoltaika, and energy community markets

Pricing: $1,499/user/year (For 3 Users plan) — all features included

Ease of Use: 2–3 week onboarding

Overall Score: 93/100

Why SurgePV Ranks #1

SurgePV connects solar design directly to proposal generation. When you change a module count or system size, the proposal updates automatically. No exporting to Excel. No rebuilding financial models from scratch.

For the Greek market, this design-to-proposal integration matters because proposals need to reflect accurate production numbers from 1,400–1,800 kWh/m² irradiation, ELOT-compliant electrical documentation, and Greek-specific financial models.

Key Strengths

• Greek net-metering modeling: Supports Law 4414/2016 framework with residential (10 kWp), commercial (100 kWp), and industrial (500 kWp) limits.
• Energy community proposals: Virtual net-metering under Law 4513/2018 with member allocation and shared benefit calculations.
• Fotovoltaika subsidy integration: Models EUR 4,000–10,000 residential grants with before/after subsidy payback scenarios.
• EUR pricing and Greek utility rates: Native EUR support with Greek electricity tariffs.
• Interactive web proposals: Mobile-friendly, shareable links. One click to send. No PDF attachments lost in spam filters.
• Greek language support: Proposals generated in Greek. For residential Fotovoltaika sales, that is not a nice-to-have — it is the difference between a homeowner who trusts your numbers and one who doesn’t.
• RES auction financials: P50/P75/P90 bankability metrics, LCOE calculation, IRR/NPV analysis. Your financing applications include the data lenders actually require.

Limitations

• Smaller US market share: Less established than Aurora Solar in the US.
• Template library: Proposal templates not as visually polished as Aurora’s.

Who Should Consider SurgePV

Greek EPCs and installers serving multiple market segments. Solar sales professionals who need Greek-specific proposals with accurate financial modeling. Book a demo to see Greek solar proposal automation in action.

You might be wondering: if SurgePV does all this, why haven’t I heard of it? Fair question. PVsyst has had a 30-year head start. Aurora Solar has spent hundreds of millions on marketing. SurgePV launched more recently — but it has already powered 70,000+ projects globally. The platform was built for the workflow gaps that legacy tools leave open, especially automated electrical engineering, which no other platform offers natively.

Aurora Solar — Beautiful Interactive Proposal Templates

Best For: Greek EPCs who prioritize visual proposal quality

Pricing: $135–259/user/month ($1,620–3,108/year)

Ease of Use: 2–3 week onboarding

Overall Score: 78/100

Why Aurora Solar Ranks #2

Aurora Solar is the US market leader with visually polished interactive web proposals. But Aurora’s proposals are built around US net-metering structures and USD pricing. Greek net-metering under Law 4414/2016 works differently. Aurora doesn’t support energy community virtual net-metering. There’s no Fotovoltaika subsidy modeling. Proposals are English-only.

Key Strengths

• Visual quality: Industry-leading proposal design and interactivity.
• AI roof detection: Fast 3D design capabilities.
• CRM integration: Native Salesforce/HubSpot connectivity.

Limitations

• US net-metering only: No Greek Law 4414/2016 support.
• No energy community modeling: Missing Law 4513/2018 support.
• English-only proposals: No Greek language option.

Who Should Consider Aurora Solar

Large teams prioritizing visual proposal quality with staff to manually adjust for Greek regulations.

---

OpenSolar — Budget Residential Proposal Tool

Best For: Small Greek residential installers on tight budgets

Pricing: $99–299/user/month

Overall Score: 68/100

Why OpenSolar Ranks #3

OpenSolar offers affordable pricing and decent interactive web proposals for residential projects. However, OpenSolar’s net-metering models don’t align with Greek Law 4414/2016. There’s no energy community support and financial modeling is basic.

Key Strengths

• Affordable: Lowest cost option for basic proposals.
• Interactive proposals: Web-based, shareable format.

Limitations

• Limited Greek support: No Greek net-metering, no energy communities.
• Basic financials: Falls short for commercial or RES auction proposals.

---

Energy Toolbase — Advanced Financial Modeling Specialist

Best For: Greek developers needing deep financial modeling for RES auction bids

Pricing: Custom enterprise pricing (typically EUR 3,000–6,000/year)

Overall Score: 74/100

Why Energy Toolbase Ranks #4

Energy Toolbase delivers the deepest financial modeling: cash flow analysis, IRR/NPV, debt service coverage, and battery storage economics. But it’s a financial tool only. No design capability. No visual proposals. You’ll need a separate design platform.

Key Strengths

• Financial depth: Deepest financial modeling available.
• P50/P90 analysis: Strong bankability metrics for auction bids.

Limitations

• No design integration: Financial tool only — requires separate platform.
• US utility focus: Greek tariffs require manual configuration.

---

Solargraf — European Installer Proposals

Best For: Greek residential installers wanting a European proposal platform

Pricing: EUR 80–150/user/month (EUR 960–1,800/year)

Overall Score: 70/100

Why Solargraf Ranks #5

Solargraf is a European company (Netherlands-based) with native EUR pricing and familiarity with European markets. However, net-metering modeling doesn’t specifically support Greek Law 4414/2016 limits, and there’s no energy community support.

Key Strengths

• European perspective: Native EUR pricing, EU market understanding.
• Straightforward proposals: Clean residential-focused output.

Limitations

• Basic design: Rooftop only, no trackers.
• Limited Greek support: No Greek net-metering or energy community modeling.

The Feature Gaps That Cost You Deals in Greece

Greek Net-Metering Modeling (Law 4414/2016)

Greece’s net-metering scheme operates under Law 4414/2016 with specific limits: 10 kWp for residential, 100 kWp for commercial, and 500 kWp for industrial, administered through HEDNO/DEDDIE. Settlement is annual (not monthly like many US programs), using retail rate offset. Your proposal software must model these exact limits and settlement rules.

Energy Community Support (Law 4513/2018)

Virtual net metering through energy communities is one of Greece’s fastest-growing solar segments. Under Law 4513/2018, communities can install up to 1 MWp and share energy among members. Only SurgePV currently offers this in an integrated proposal platform.

Fotovoltaika Subsidy Integration

The Fotovoltaika sto stegi program provides EUR 4,000–10,000 in residential subsidies. Proposals that show the subsidy impact on payback period — reducing it from 6–10 years to 4–6 years — close significantly more deals.

EUR Pricing and Greek Utility Rates

All financial projections must be in EUR. Greek electricity tariffs vary: residential (EUR 0.15–0.25/kWh), commercial (EUR 0.12–0.20/kWh), and industrial (EUR 0.10–0.16/kWh).

Greek Language Support

For residential Fotovoltaika sales and energy community prospectuses, Greek-language proposals are necessary. A homeowner in Thessaloniki or a municipal energy community on Rhodes expects documentation in Greek.

RES Auction Financial Rigor

Utility-scale RES auction proposals administered by DAPEEP require P50/P75/P90 production scenarios, LCOE calculations, and NPV/IRR/debt service coverage analysis for RAE competitive bidding. According to IRENA, Greece’s auction-driven growth model has been among the most successful in Southern Europe. HELAPCO tracks auction results and market development data for the Greek PV sector.

Frequently Asked Questions

What is the best solar proposal software in Greece?

SurgePV is the best all-in-one solar proposal software for Greece in 2026. It combines Greek net-metering modeling (Law 4414/2016), energy community support (Law 4513/2018), Fotovoltaika subsidy integration (EUR 4,000–10,000), EUR pricing, and Greek language proposals with full design-to-proposal workflow at $1,499/user/year. See our best solar software hub for broader comparisons.

Can proposal software model Greek net-metering (Law 4414/2016)?

Yes. SurgePV supports Greek net-metering with 10 kWp (residential), 100 kWp (commercial), and 500 kWp (industrial) limits, annual settlement, and retail rate offset modeling. Most other platforms use US net-metering frameworks that don’t match Greek regulations administered through HEDNO.

Does proposal software support energy communities in Greece?

SurgePV supports virtual net metering for Greek energy communities (Law 4513/2018) with member allocation, shared benefit calculations, and up to 1 MWp system modeling. Aurora Solar, OpenSolar, and Energy Toolbase do NOT support energy community proposals.

Can proposal software integrate Fotovoltaika subsidies?

Yes. SurgePV models Fotovoltaika sto stegi subsidies (EUR 4,000–10,000 residential grants) showing with/without subsidy payback scenarios. This reduces typical payback from 6–10 years to 4–6 years in Greece’s 1,400–1,800 kWh/m² irradiation, making proposals significantly more compelling for Greek homeowners.

Are Greek-language proposals available in solar software?

SurgePV supports Greek-language proposals essential for residential Fotovoltaika sales and energy community prospectuses. Aurora Solar, Energy Toolbase, and Enact Systems provide English-only proposals.

How much does solar proposal software cost in Greece?

Solar proposal software pricing for Greece ranges from $1,499/user/year (SurgePV, all features included with design integration) to EUR 960–1,800/year (Solargraf) to $1,620–3,108/year (Aurora Solar). Enterprise platforms like Energy Toolbase use custom pricing (EUR 3,000–6,000/year typical).

What proposal software is best for Greek RES auctions?

For Greek RES auctions, SurgePV and Energy Toolbase provide P50/P75/P90 bankability metrics, LCOE calculation, and IRR/NPV analysis required for RAE competitive bidding and project financing. SurgePV includes design integration; Energy Toolbase requires a separate design tool.

Can proposal software auto-update from design changes?

Yes. SurgePV proposals auto-update when design parameters change (module count, system size, component costs), ensuring proposals always match the current design. Aurora Solar and OpenSolar also offer design-to-proposal integration. Energy Toolbase does NOT — financial modeling only. See our best solar design software guide for design tool comparisons.

What ROI metrics do Greek solar customers expect in proposals?

Greek solar customers expect proposals showing payback period (5–8 years commercial, 4–6 years residential with subsidy), IRR (12–18% for commercial), NPV, and LCOE (EUR 0.04–0.07/kWh for utility-scale). All metrics must be in EUR with Greek utility rate structures.
