If you are shortlisting the best solar design software in Poland for 2026, the deciding factor is not shading physics or how pretty the 3D roof looks. It is whether the financial engine models net-billing correctly. Poland switched prosumers from net metering to net-billing on 1 April 2022, and most design platforms sold into Poland were written for a net metering world and quietly still behave like it. A tool that credits exported kWh against imported kWh will overstate a Polish homeowner’s savings by a wide margin, and the customer discovers it on the first winter bill. The platform that wins our 2026 bench is SurgePV, a cloud-native all-in-one suite at US$1,299 per user per year on the 5-User Team plan (roughly PLN 4,700 at about PLN 3.6 to the dollar). Below are the ten platforms Polish instalatorzy genuinely shortlist, each priced in the currency its vendor actually bills in, with honest limitations on each including ours. You can compare SurgePV pricing before you talk to anyone in sales.
Direct answer. The best solar design software in Poland for 2026 is SurgePV, at US$1,299 per user per year on the 5-User Team plan (US$6,495 for five seats, roughly PLN 23,400). It models the net-billing prosument settlement rather than net metering, values exports against hourly RCE prices with the 1.23 correction coefficient applied from 1 February 2026, tracks the 12 month prosumer deposit and its refund cap, labels drawings to PN-HD 60364 conventions, prepares the connection paperwork for PGE, Tauron, Enea and Energa, and runs 8,760-hour module-level shading. For lender-grade yield reports on farm-scale projects, PVsyst is still the document the bank asks for by name.
This guide is written for Polish installation firms, EPC contractors and in-house design teams shipping five or more projects a month. We rank ten platforms on four criteria: Polish regulatory depth, engineering rigour, workflow coverage from address to signed umowa, and total cost of ownership in złoty across a five-person team.
Net-Billing Is the Whole Argument in Poland
Under the old net metering system, a Polish prosument exported surplus energy and drew it back later at a ratio of 1 to 0.8 for systems up to 10 kW. The grid worked as a free battery with a 20 percent haircut. That system closed to new entrants on 31 March 2022. Everyone who signed a connection agreement after that date settles under net-billing, and the arithmetic is completely different.
Under net-billing, exported energy is sold at a market price and imported energy is bought at the full retail tariff including distribution charges. The sale proceeds go into a depozyt prosumencki, a prosumer deposit, which is then spent against future bills. Three consequences follow that a design tool has to represent honestly.
The buy price and the sell price are not the same number. A Polish household buys at a retail rate that carries the energy component plus the distribution and system charges, while it sells at a bare wholesale market price. The gap between the two is the single largest driver of payback in every Polish residential proposal written today. Self-consumption is worth roughly two to three times what an exported kWh is worth, which is why storage and load shifting entered the Polish residential conversation so quickly.
The market price is now hourly, not monthly. Prosumers who entered the system before 1 July 2024 settle against RCEm, a monthly average market price. New prosumers settle against RCE, the hourly market price, and since 30 September 2025 the price is published in 15 minute intervals. Hourly settlement is materially worse for an unshifted south-facing array, because the hours a PV system exports hardest are exactly the hours when the market price collapses. Summer midday RCE hitting zero or going negative is now a routine event on the Polish grid, and a tool applying one annual average price to every exported kWh is producing fiction.
Two adjustments soften it. From 1 February 2026 a correction coefficient of 1.23 is applied to the value of energy fed into the grid, which raises export income by 23 percent and compensates for the fact that a prosumer cannot reclaim VAT on the electricity they buy back. And unused deposit is refunded in cash, capped at 30 percent of the value of energy exported in a given month for prosumers on hourly RCE settlement, and 20 percent for those still on RCEm. A model that ignores the refund cap overstates the value of an oversized array, because everything above the cap simply expires after 12 months.
📘 Regulation note
Poland's prosumer settlement rules sit in the ustawa o odnawialnych źródłach energii and are administered with the Urząd Regulacji Energetyki setting tariffs and Polskie Sieci Elektroenergetyczne publishing the RCE market price series. Micro-installations up to 50 kW connect by notification to the local distribution operator, larger systems by application. Verify the current coefficient and refund cap before you put a 20 year cash flow in front of a customer, because both have moved twice since 2022.

Poland built one of the fastest residential PV markets in Europe between 2019 and 2021, on the back of net metering plus Mój Prąd. Then the settlement rules changed and the residential segment stalled. Poland’s cumulative PV capacity reached roughly 25 GW at the end of 2025 after adding about 3.6 GW during the year, according to pv magazine, February 2026. But the shape of that growth flipped. Farms above 1 MW now take roughly half of new capacity, while the sub-50 kW prosumer segment installed just under 1 GW in 2025 against 1.3 GW in 2024.
Three practical effects on software selection. First, the residential job is now a sizing and self-consumption exercise rather than a maximise-the-roof exercise, so the tool has to model a load profile, not just a generation curve. Second, the commercial and farm segment is where volume moved, so bankable yield output and ground-mount layout matter more to a Polish firm in 2026 than they did in 2021. Third, margin pressure after the slowdown means a five-seat software bill of PLN 40,000 a year is no longer casually absorbed. Total cost of ownership is a real selection criterion here in a way it is not in Germany.

Standards, Operators and the Paperwork Path
The electrical code is the PN-HD 60364 series. Poland adopted the CENELEC harmonisation documents, so a Polish installation is designed and verified to PN-HD 60364, with PN-HD 60364-7-712 covering photovoltaic power supply systems specifically, PN-EN 62446-1 governing commissioning documentation and the test report, and PN-EN 62305 where lightning protection is in scope. A single-line diagram labelled to NEC 690 conventions is not a drawing a Polish operator’s inspector will process without comment, and the protokół odbioru your electrician signs references the PN-HD test sequence.
Five distribution operators, five procedures. PGE Dystrybucja, Tauron Dystrybucja, Enea Operator, Energa-Operator and Stoen Operator each run their own forms, portals and lead times. A micro-installation up to 50 kW is connected by zgłoszenie, a notification submitted before energisation with the schemat and the inverter certificate attached, and the operator fits the bidirectional meter. Above 50 kW you move to a wniosek o określenie warunków przyłączenia, a formal application with warunki przyłączenia issued before you build. The workflow difference matters: below the threshold a salesperson can promise a date, above it they cannot.
- Confirm the connection route. Under 50 kW is a zgłoszenie. Over 50 kW needs warunki przyłączenia from the operator first, and the timeline moves from weeks to months.
- Check the existing connection capacity. The moc przyłączeniowa on the customer’s existing agreement caps what you can install without an amendment. This is the most common cause of a redesign after signature.
- Produce the schemat and documentation to PN-HD 60364. Inverter grid-code certificate, protection settings, DC and AC isolation, earthing and surge protection.
- Submit the zgłoszenie to the correct operator portal. PGE, Tauron, Enea, Energa and Stoen all differ in what they accept and in what format.
- Register the prosumer settlement. The supply agreement has to move the customer onto net-billing with the correct RCE or RCEm basis, and the deposit only starts accruing once that is done.
⚠️ Watch out
Do not size a Polish array to the roof. Size it to the load profile, then check the export against the prosumer deposit refund cap. Every kWh of deposit above 30 percent of monthly export value expires unused after 12 months, so the last two kilowatts on an oversized south-facing array can be worth almost nothing.
The 4-Point Poland Bench Test
This is the framework we use internally before deploying any design platform on our own solar EPC work. Each tool scores 1 to 10 on four axes, out of 40. Nothing below 32 gets deployed.
- Polish regulatory depth. Net-billing settlement with RCE hourly or RCEm monthly basis, the 1.23 correction coefficient, prosumer deposit tracking with the 12 month expiry and the refund cap, Mój Prąd grant handling, PN-HD 60364 labelling on the generated schemat, and operator documentation for PGE, Tauron, Enea, Energa and Stoen.
- Engineering rigour. 8,760-hour module-level simulation, P50, P75 and P90 outputs in the format Polish lenders typically ask for on farm-scale work, snow load inputs to the mounting structure, and low-temperature Voc string sizing for a design low around minus 20 Celsius.
- Workflow coverage. Address to PN-HD labelled schemat to zestawienie materiałów to branded Polish-language oferta in one licence, with DXF or DWG export for the structural engineer.
- Total cost of ownership in złoty. Licence plus add-ons plus onboarding time, per finished project, across five people.
Scores across the ten platforms: SurgePV 37, PVSOL premium 33, PVsyst 30, Huawei FusionSolar Design 26, HelioScope 29, Aurora Solar 26, OpenSolar 29, SolarEdge Designer 24, Fronius Solar.creator 23, PVcase 26. The scoring is ours and it is opinionated. The gap between SurgePV and PVSOL is four points, which is not enough to justify retraining a team of experienced PV*SOL designers who are already fast.
Top 10 Solar Design Software in Poland Compared
Pricing below is 2026, taken from each vendor’s own published page and quoted in the currency that vendor bills in. Where we add a PLN figure it is an approximate conversion at roughly PLN 3.6 to the US dollar, PLN 4.3 to the euro and PLN 4.6 to the Swiss franc, and it moves with the exchange rate.
| # | Platform | Vendor price (mid plan) | Key capability | Best for |
|---|---|---|---|---|
| 1 | SurgePV | US$1,299/user/yr (~PLN 4,700) | All-in-one design, net-billing modelling, PN-HD labelled schemat, Polish proposals | Installers and EPCs doing 5+ projects a month |
| 2 | PV*SOL premium | EUR 845/named user/yr + VAT (~PLN 3,600) | 3D shading walkthrough, deep European component database | Established Polish design offices |
| 3 | PVsyst | CHF 700/user/yr (~PLN 3,200) | Reference-grade simulation physics | Farm-scale developers and lender due diligence |
| 4 | Huawei FusionSolar Design | Not publicly listed | Fast string and storage design on Huawei hardware | Installers standardised on Huawei inverters |
| 5 | HelioScope | $259/user/mo Pro ($2,640/yr) | Bankable C&I yield simulation | Consultancies on commercial rooftops |
| 6 | OpenSolar | Core platform free | Free design tier with clean residential templates | Solo installers under 3 designs a month |
| 7 | Aurora Solar | $220/user/mo Premium billed annually ($2,640/yr) | Deepest residential design and sales workflow | Multinationals extending an Aurora process |
| 8 | SolarEdge Designer | Free | String design inside the SolarEdge product line | SolarEdge-heavy installers |
| 9 | Fronius Solar.creator | Free | Fast Fronius inverter configuration and sizing | Fronius-heavy installers |
| 10 | PVcase | Not publicly listed, quote only | Terrain-aware ground-mount layout in AutoCAD | Farm developers on sloped land |
The honest read: positions 1 through 3 are the real choice for a Polish firm doing mixed residential and commercial work. Positions 4, 8 and 9 are free manufacturer tools that most Polish installers already have open in a second tab, and there is nothing wrong with that. Positions 5, 7 and 10 are imports or specialists.
1. SurgePV
What it does best. SurgePV runs the full motion in one licence: satellite address to AI-generated 3D roof, 8,760-hour module-level shading, string sizing, PN-HD 60364 labelled single-line diagram, zestawienie materiałów, financial model and white-label oferta in Polish. For Poland specifically, the financial engine is built around net-billing rather than retro-fitted onto a net metering model. It settles exports against hourly RCE or monthly RCEm depending on when the prosumer entered the system, applies the 1.23 correction coefficient, tracks the prosumer deposit with its 12 month expiry and its refund cap, and shows self-consumption value separately from export value so a customer can see why a battery changes the answer. Mój Prąd is modelled as a grant line with the component structure rather than a single lump. Clara AI takes plain instructions such as “zaprojektuj instalację 8 kWp, dach dwuspadowy, orientacja wschód zachód, magazyn 10 kWh”.
Pricing. US$1,299 per user per year on the 5-User Team plan, so US$6,495 for five seats, roughly PLN 4,700 per seat and PLN 23,400 for the team. Individual seats are US$1,899 a year, about PLN 6,800. Enterprise is quoted. Free trial, no credit card. Worth saying plainly: an Aurora Basic seat at $1,620 a year is cheaper than a SurgePV Individual seat, and OpenSolar’s core platform costs nothing at all. SurgePV earns its price on bundled scope, not on being the cheapest line item.
Who it suits. Polish installation firms and EPCs doing five or more designs a month, teams quoting residential alongside commercial rooftops, and firms currently running PV*SOL plus a spreadsheet plus a separate proposal tool.
Honest limitations. Four real ones. Brand recognition in Poland is thin: SurgePV launched in 2025, and a bank’s technical adviser reviewing a 2 MW farm has never seen its report format, where a PVsyst output needs no introduction. It does not submit to the PGE, Tauron, Enea or Energa portals on your behalf, it prepares the documentation and a human uploads it, which on a five-operator market is a real chunk of admin left on the table. The component database is deep on modules and inverters but thinner on the smaller Polish mounting-system suppliers, so procurement still checks the konstrukcja line by hand and many firms fall back to a manufacturer configurator such as Corab’s for that step. And the Polish-language interface is complete for the customer-facing proposal but the engineering settings still read in English, which slows a junior designer down for the first fortnight.
Book a SurgePV demo and bring a real Polish project so you can judge the net-billing model and the PN-HD output on your own job rather than a showcase file.
2. PV*SOL premium
What it does best. Valentin Software’s desktop tool is the incumbent across Central Europe and it earned that position. The 3D shading walkthrough is the most persuasive customer-facing shading explanation in any tool on this list, the component database covers European hardware in depth, inverter matching is careful, and it handles the awkward roof geometry common in Polish housing stock without a fight. A Polish design office with five years of PV*SOL muscle memory is genuinely faster in it than in anything else.
Pricing. EUR 845 per named user per year plus VAT for PVSOL premium, with standard PVSOL at EUR 585. That is roughly PLN 3,600 a seat, and five premium seats come to EUR 4,225. It undercuts SurgePV’s five-seat price outright, and for a stable two person office it is cheaper still.
Who it suits. Established Polish biura projektowe with experienced designers whose deliverable is a technical yield report rather than a sales document.
Honest limitations. Windows desktop, so no live collaboration and no working from a phone on a roof. Its net-billing modelling is generic rather than Polish-specific, so the deposit, the refund cap and the correction coefficient end up in a spreadsheet next to it. Proposal output is not a sales document. No AI assistant and no satellite-derived roof capture, so the first stage of every job is manual. Our PV*SOL alternative comparison covers the tradeoff in detail.
3. PVsyst
What it does best. PVsyst remains the reference simulation engine and the document a Polish bank’s technical adviser asks for by name on a financed farm. Its near-shading model, horizon handling, documented loss tree and parametric studies are the benchmark everything else is measured against, including ours. On bankability specifically it beats SurgePV, and we will not pretend otherwise.
Pricing. CHF 700 per user per year for the Professional annual subscription, roughly PLN 3,200. Five seats are CHF 3,500 before the 5 to 20 percent group discount, which is well under SurgePV’s five-seat price. Education is CHF 420, Training and Research CHF 560, Student CHF 25 and PVsystCLI CHF 3,000.
Who it suits. Independent engineers, due diligence teams and the farm-scale developers who now account for half of Poland’s new capacity.
Honest limitations. Windows desktop, a steep learning curve, and no design workflow in the sense an installer means it. No proposals, no net-billing modelling, no Mój Prąd handling and no PN-HD documentation output. It is a physics tool, not a business tool. Our PVsyst alternative guide sets out where the line sits.
4. Huawei FusionSolar Design
What it does best. Huawei holds a very large share of the Polish residential inverter market, and its design tool configures strings, optimisers and storage against that hardware quickly and accurately, with the grid-code parameter sets the inverters ship with for Poland already loaded. If most of your jobs are Huawei, having it open catches configuration errors before they reach site.
Pricing. Not publicly listed. Access runs through an installer SmartPVMS account and Huawei publishes no price or plan table, so ask your distributor what it costs rather than assuming it is free.
Who it suits. Polish installers standardised on Huawei inverters and LUNA storage.
Honest limitations. It is a manufacturer tool built to sell that manufacturer’s hardware, so multi-vendor comparison is not its purpose. Shading is simplified against a dedicated simulator, there is no Polish-language sales proposal a customer would sign, no net-billing cash flow with deposit tracking, and no bankable report. A useful second window, not a platform.
5. HelioScope
What it does best. Module-level 8,760-hour simulation for commercial and industrial roofs with a clean loss tree that independent engineers accept without argument. For a 500 kW hala magazynowa roof it is defensible, and Poland’s commercial rooftop segment is one of the few parts of the market still growing steadily.
Pricing. Basic is $159 per user per month ($1,620 a year) and Pro is $259 ($2,640 a year), each covering one user and 10 projects a month, with DC design caps of 1.25 MW on Basic and 5 MW on Pro. Five Pro seats are $13,200 a year, roughly PLN 47,500. HelioScope is Aurora-owned.
Who it suits. Consultancies and C&I-only teams whose deliverable is a yield report.
Honest limitations. No Polish regulatory layer at all, no net-billing modelling, no PN-HD labelling, no AI roof capture, and weak proposal tooling that forces a second licence. Read our HelioScope alternative analysis before committing five seats at that price in a margin-compressed market.
6. OpenSolar
What it does best. A free design tier with polished residential templates and a short learning curve. For a one-person firm doing two or three jobs a month in Poland’s current residential conditions, the price is hard to argue with.
Pricing. The core platform is free. From 16 April 2026 OpenSolar charges for API Access on a per project basis and for Connectors on a flat monthly basis, but it has not published those rates and they vary by geography, so budget for them by asking OpenSolar directly.
Who it suits. Solo installers and new entrants who need working proposals without a licence commitment.
Honest limitations. Polish regulatory support is shallow and the financial model needs manual work to behave like net-billing. No bankable output for financed commercial work. On cost there is nothing to argue about: a free platform beats SurgePV’s price and we are not going to pretend otherwise, so the question is only whether the Polish settlement modelling and the PN-HD documentation are worth paying for in your workflow. See our OpenSolar alternative comparison.
7. Aurora Solar
What it does best. The deepest residential design and sales workflow in the English-speaking market, with mature roof plane detection and excellent customer-facing presentation. If your group already runs Aurora in another country, standardising has real value.
Pricing. Basic is $135 per user per month billed annually ($1,620 a year, $159 if you pay monthly) and Premium is $220 billed annually ($2,640 a year, $259 monthly), each covering one user and 50 projects a month. Enterprise is custom. Five Basic seats are $8,100 a year and five Premium seats $13,200. LIDAR modelling, bankable shade reports and battery modelling sit on Premium, and plan sets are a separately priced service rather than a plan inclusion, with site models from $9.99. Note that a Basic seat at $1,620 a year undercuts a SurgePV Individual seat at $1,899.
Who it suits. Multinational installers extending an existing Aurora process into Poland.
Honest limitations. The Polish regulatory layer is effectively absent. No net-billing settlement, no RCE price series, no prosumer deposit logic, no Mój Prąd handling and no PN-HD labelling. Pricing is in US dollars, so a Polish buyer carries the exchange rate risk, and the features a Polish commercial job tends to need sit on the Premium tier rather than Basic. See our Aurora Solar alternative writeup.
8. SolarEdge Designer
What it does best. Free, fast string design inside the SolarEdge product line, with accurate optimiser and inverter matching and sensible handling of the module-level shading that SolarEdge hardware exists to solve.
Pricing. Free.
Who it suits. Installers whose default hardware is SolarEdge.
Honest limitations. Single-vendor by design, no Polish financial modelling, no PN-HD documentation set and no proposal a Polish customer would sign. It answers the string question and stops there.
9. Fronius Solar.creator
What it does best. Fast configuration and string sizing against Fronius inverters, with clear warnings when a string falls outside the input window. Fronius has a long-established Polish installer base and the tool is free.
Pricing. Free.
Who it suits. Fronius-heavy Polish installers doing residential and light commercial.
Honest limitations. Same shape of limitation as the other manufacturer tools, and narrower. No shading simulation worth the name, no net-billing model, no documentation output and no proposal. Keep it for the sizing check, not for the job.
10. PVcase
What it does best. Terrain-aware ground-mount layout inside AutoCAD, which matters on Polish farm sites where slope and irregular działka boundaries drive row spacing and pile schedules. With farms above 1 MW taking half of new Polish capacity, this segment is no longer niche.
Pricing. Not publicly listed. PVcase quotes per customer and the software requires an AutoCAD licence on top, so any per-seat figure circulating in software directories is an unverified third-party estimate.
Who it suits. Farm developers and ground-mount EPCs.
Honest limitations. No rooftop or residential relevance, no proposal workflow, and it assumes an AutoCAD-competent operator. Most readers of this article are outside its target market. Our PVcase alternative comparison covers the cheaper routes.

| PVcase | Not publicly listed | Not publicly listed | Not publicly listed, plus AutoCAD | Ground mount CAD only |
The comparison a Polish firm should actually run is SurgePV at $6,495 for five seats against the common stack of PVSOL for design plus a spreadsheet for net-billing plus a separate tool for the oferta. On licence cost alone the alternatives win, and we will say it straight: five PVSOL premium seats at EUR 4,225 and five PVsyst seats at CHF 3,500 are both cheaper than five SurgePV seats, and OpenSolar’s core platform is free. What it does not price is the designer hour spent rebuilding a settlement model every time the coefficient or the refund cap moves, which has now happened twice since 2022.
Polish Design Details Most Software Gets Wrong
Three specifics decide whether a Polish design survives contact with a real bill.
The winter mismatch is severe and it is the reason heat pumps are in the conversation. Poland’s annual specific yield sits around 1,000 to 1,100 kWh per kWp for a well-oriented array, but December and January together typically deliver only a few percent of that. Heating season demand peaks precisely when generation collapses. Under net metering this barely mattered because the grid banked summer surplus. Under net-billing it matters enormously, because summer surplus is sold at collapsed midday prices and winter import is bought at full retail. Any Polish proposal that bundles PV with a heat pump has to model the seasonal profile honestly, or it promises a heating bill that will not arrive. A tool showing only annual totals hides the single biggest risk in the quote.
Snow load is a design input, not a default. Mountain and southern regions carry characteristic ground snow loads far above the central plain, and the same mounting structure and ballast plan is not valid in both. If your tool applies one national default, the konstruktor redoes the work.
Low-temperature Voc still catches people. String open-circuit voltage rises as temperature falls, and a Polish design low around minus 20 Celsius in the north east pushes a string sized at 25 Celsius past the inverter’s maximum DC input. It is legal in October and over voltage in January. Our sister engineering team covers the arithmetic in their solar inverter sizing guide, and the underlying concept sits in our kWp glossary entry and the shading loss definition.
Mistakes Polish Installers Make Choosing Design Software
-
1
Buying a tool that still models net metering. If the savings figure comes from netting exported kWh against imported kWh, the proposal is wrong by the buy-sell spread on every single unit. This is the number one failure and it is invisible until the first bill.
-
2
Applying one annual average price to hourly RCE settlement. PV exports hardest in the hours the market price is lowest. An annual average flatters export income by a wide margin on an unshifted south-facing array.
-
3
Ignoring the deposit refund cap and the 12 month expiry. Unused prosumer deposit above the cap simply lapses. Oversizing past that point adds cost and adds no income.
-
4
Not checking moc przyłączeniowa before signature. The customer's existing connection capacity caps the install. Discovering it after the deposit is taken means a redesign and an awkward call.
-
5
Assuming one operator procedure fits all five. PGE, Tauron, Enea, Energa and Stoen differ in forms, portals and lead times. A template built for one produces rejections in the others.
These patterns are not unique to Poland in kind, only in detail. Our writeup on common mistakes EPC companies make in rooftop solar covers the wider set.
Should a Polish Installer Standardise on SurgePV?
- ✓ You design 5+ Polish projects a month
- ✓ You quote PV with storage or a heat pump
- ✓ Your net-billing model currently lives in a spreadsheet
- ✓ You work across two or more distribution operators
- ✗ You are a stable 2 person office fluent in PV*SOL
- ✗ Your deliverable is a bankable farm yield report (PVsyst)
- ✗ Every job you sell is Huawei and under 10 kWp (FusionSolar)
- ✗ You develop farms on sloped land (PVcase)
Verdict. For a five-person Polish firm covering residential and commercial rooftops, SurgePV wins on bundled scope and on the one thing that decides a Polish proposal’s honesty, which is the net-billing settlement model. For a two-person office fluent in PVSOL with a technical deliverable, PVSOL plus a maintained settlement spreadsheet is still a defensible answer, and we would say so on a sales call.
How Heaven Green Energy and SurgePV Help Polish Teams
Heaven Green Energy has delivered more than 10,000 solar installations, and our engineering group builds the software we use ourselves. SurgePV came out of that: a design suite written by people who had to produce inspection-ready drawings on deadline, in a market where the settlement rules changed under them. For Polish teams the entry points are:
- Shadow analysis for 8,760-hour module-level shading on complex roofs.
- Structural and civil engineering for snow and wind load verification on the mounting structure.
- 3D pre-design from satellite imagery when you need a roof model before a site visit.
- QBits Energy string sizing calculator for a fast low-temperature Voc check.
If you also run projects outside Poland, our commercial solar and industrial solar pages set out how the same design stack carries across markets. Broader market context sits with the IEA renewables tracker and IRENA country profiles.

Frequently Asked Questions
What is the best solar design software in Poland in 2026?
SurgePV ranks first on our 4-point Poland bench with 37 of 40, at US$1,299 per user per year on the 5-User Team plan (US$6,495 for five seats, roughly PLN 23,400), because it models the net-billing prosument settlement natively and bundles PN-HD 60364 labelled drawings, 8,760-hour simulation and a Polish-language proposal in one cloud licence.

Under net-billing, introduced on 1 April 2022, you sell surplus energy at a market price and buy energy back at the full retail tariff including distribution charges. The two prices are not equal, so a self-consumed kWh is worth roughly two to three times an exported one. Sale proceeds go into a prosumer deposit that must be used within 12 months. A proposal built on the old net metering logic overstates savings on every exported unit.
What is the RCE price and why does hourly settlement matter?
RCE is the hourly market price of electricity used to value energy a prosumer exports. Prosumers who joined from 1 July 2024 settle hourly rather than against the monthly RCEm average, and since 30 September 2025 prices are published in 15 minute intervals. Hourly settlement penalises unshifted south-facing arrays, because peak export coincides with the hours market prices are lowest. Storage, load shifting and east-west layouts all improve under it.
What is the prosumer deposit refund cap?
Unused funds in the depozyt prosumencki are refunded in cash, but only up to 30 percent of the value of energy fed into the grid in a given month for prosumers on hourly RCE settlement, and 20 percent for those still on the monthly RCEm basis. Anything above the cap expires after 12 months. This puts a practical ceiling on how much oversizing pays, and any tool that ignores it will recommend arrays that are too big.
How much is the Mój Prąd grant in 2026?
The 2026 edition runs at roughly PLN 7,000 for a photovoltaic installation on its own, rising to about PLN 31,000 when electricity storage, heat storage and an energy management system are added, with electricity storage carrying the largest single component at up to around PLN 16,000. The programme is run by NFOŚiGW. Confirm the current call terms before quoting, because the component amounts and the budget have changed with every edition.
Which standards apply to a Polish PV installation?
Poland works to the PN-HD 60364 series adopted from CENELEC, with PN-HD 60364-7-712 covering photovoltaic power supply systems, PN-EN 62446-1 governing commissioning documentation and the test report, and PN-EN 62305 where lightning protection is in scope. Drawings labelled to NEC 690 conventions will not read correctly to a Polish inspector, and the acceptance protocol your electrician signs references the PN-HD test sequence.
Do I need approval from PGE or Tauron before installing?
For a micro-installation up to 50 kW the route is a zgłoszenie, a notification to the local distribution operator submitted before energisation with the schematic and inverter certificate attached, after which the operator fits the bidirectional meter. Above 50 kW you need warunki przyłączenia issued in response to a formal application before you build. PGE, Tauron, Enea, Energa and Stoen each run their own forms and portals, so a template built for one operator gets rejected by another.
What is SurgePV’s biggest weakness for Polish installers?
Brand recognition and portal integration. SurgePV launched in 2025, so a bank’s technical adviser on a farm-scale project has never seen its report format, where a PVsyst output needs no introduction. It also prepares the operator documentation rather than submitting it, which across five distribution operators leaves real admin on the table. Its mounting-system database is thinner on smaller Polish suppliers than on modules and inverters, and the engineering settings are still in English even though the customer-facing proposal is fully Polish.
