TL;DR: SurgePV is the best solar proposal software for Lithuania — combining integrated design-to-proposal workflow, native ESO net metering modeling, feed-in premium calculations, and branded templates in one platform at $1,899/year for 3 users. OpenSolar is the affordable residential alternative ($50-150/month). Energy Toolbase leads for commercial + storage financial analysis. Aurora Solar suits international teams. Solargraf delivers speed for high-volume residential sales.
Lithuanian solar installers face a math problem. Over 50 companies compete for commercial and residential projects across Vilnius, Kaunas, and Klaipeda. Customers request 3-5 quotes before deciding. And the installer who delivers a professional, accurate proposal first wins the deal 40% of the time (SolarPower Europe).
Yet most Lithuanian installers still build proposals manually. Design calculations in one spreadsheet. Net metering economics in another. Financial scenarios typed into a Word template. The result: 4-8 hours per proposal, pricing errors that compress margins, and inconsistent quality that costs deals.
The best solar proposal software for Lithuania automates financial modeling (ESO net metering, feed-in premiums, green loan scenarios), generates branded proposals in under 1 hour, and integrates directly with your design workflow so you never re-enter data.
In this guide, you’ll learn:

Best Solar Proposal Software in Lithuania (Detailed Reviews)
SurgePV — Best End-to-End Platform for Lithuanian Solar Proposals
Best For: Commercial installers, EPCs, and growing solar teams
Pricing: $1,899/year (3 users); $1,499/user/year (For 3 Users plan)
Proposal Speed: Under 1 hour from design to customer-ready document
SurgePV is a cloud-based solar design and proposal platform that combines layout design, simulation, electrical engineering, and professional proposals in a single workflow — eliminating the need for separate design, proposal, and financial modeling tools.
For Lithuanian installers, the integrated workflow is where the real value lies.
Here’s the problem most teams face: you design a system in one tool, then manually re-enter all the data into a proposal template. Equipment specs, production estimates, financial scenarios — everything typed twice. That workflow invites errors, wastes 2-3 hours per project, and produces inconsistent results depending on who’s building the proposal.
SurgePV eliminates that entirely. Design flows directly into the proposal. Every number matches because it’s the same platform.
Key Features for Lithuania
- ESO net metering calculator — Accurate annual bill savings using Lithuania’s 1:1 credit ratio and annual reconciliation rules. That means your customer sees exactly what they’ll save — not a rough estimate that erodes trust when the first ESO bill arrives.
- Feed-in premium modeling — Calculate auction-based revenue for projects above 30 kW (EUR 0.05-0.08/kWh). Multi-scenario comparison built in.
- Lithuanian tax incentive integration — Incorporate 9% reduced VAT, 4-year accelerated depreciation, and property tax exemptions automatically.
- Green loan scenarios — Model financing from SEB Bank, Swedbank, and Luminor at 3.5-6.5% interest. Present cash purchase vs. loan vs. leasing side by side.
- Branded templates — Customizable with your company logo, colors, and formatting. Professional presentation signals installation quality to Lithuanian customers.
- Financial modeling — EUR-based calculations with volatile Lithuanian electricity price scenarios (0.08-0.18 EUR/kWh). ROI, payback period, and LCOE included.
Pro Tip
SurgePV’s design-to-proposal flow means zero data re-entry. Design a system, generate a proposal, and send it to your customer — all within 1 hour. That’s 3-7 hours faster than manual workflows. Book a demo to see the full workflow.

What Wins Deals in Lithuania: The Proposal Requirements That Matter
Lithuanian Financial Modeling Accuracy
Proposals must accurately reflect Lithuanian net metering rules (ESO annual reconciliation, 1:1 credit up to 500 kW), feed-in premium rates (auction-based EUR 0.05-0.08/kWh), and tax incentives (9% VAT, accelerated depreciation). A proposal with wrong numbers doesn’t just lose the deal — it damages your reputation with every customer who talks to their neighbor. SurgePV handles these calculations natively. Other tools require manual spreadsheet work.
Professional Presentation and Branding
In a market with 50+ competing installers, proposal quality is a proxy for installation quality. Lithuanian customers compare proposals side by side. The one with 3D renderings, branded formatting, and clear financial charts wins more often than the generic PDF from a spreadsheet. This isn’t about aesthetics — it’s about trust.
Speed: The 48-Hour Rule
Lithuanian customers expect proposal turnaround within 24-48 hours for residential and 3-5 days for commercial. Manual workflows that take 4-8 hours per proposal mean your team can handle 2-3 proposals per day at most. Automated software (SurgePV, Solargraf) pushes that to 5-8 proposals per day — a direct revenue multiplier.
Design Integration vs. Standalone
Integrated platforms (SurgePV, Aurora Solar) eliminate data re-entry between design and proposal — reducing errors and saving 1-2 hours per project. Standalone tools (Energy Toolbase, Solargraf) require manual input from your design software, which introduces risk every time someone types a number.
Our Testing Methodology
We evaluated each platform against five weighted criteria specific to Lithuanian proposal workflows:
- Proposal speed (25%) — Timed from design completion to customer-ready PDF. Tested with 10 commercial and 10 residential Lithuanian projects. Target: under 1 hour for commercial, under 30 minutes for residential.
- Financial accuracy (25%) — Validated net metering calculations against ESO billing rules, verified tax incentive modeling against Lithuanian tax code, tested financing scenarios against SEB Bank and Swedbank loan terms.
- Customization and branding (20%) — Assessed template flexibility, branding options, Lithuanian language support, visual design quality (3D renderings, charts, formatting).
- Ease of use (15%) — Hands-on testing with Lithuanian sales teams at beginner to expert experience levels, learning curve assessment, mobile access testing.
- Integration and workflow (15%) — Tested design-to-proposal workflow, CRM connectivity, e-signature capabilities, multi-user collaboration.
Testing was conducted between December 2025 and January 2026, using real Lithuanian project data from commercial (100-250 kW) and residential (5-10 kW) installations.
