Poland built one of Europe’s fastest-growing prosumer solar markets on a net-metering arrangement that no longer exists. The switch to net-billing in 2022 changed the economics overnight: exported energy is now settled at a market reference price rather than swapped one-for-one against imports. Systems designed under the old logic, sized generously because export was effectively storage, stopped making sense. Most Polish design workflows have not fully adjusted.
Direct answer. The best solar design software in Poland for most installers is SurgePV or PVsyst for commercial work, and a Polish-market domestic tool for prosumer installations, because the design problem is now matching generation to consumption hour by hour rather than filling the roof. Connection conditions from the local OSD and PN-EN standards govern the technical package, and no international platform templates them.
TL;DR
- Net-billing replaced net metering in 2022. Export is settled at a market reference price, not swapped against imports.
- Self-consumption now carries the payback, so hourly modelling replaced annual arithmetic.
- Grid connection runs through the local OSD, and connection refusals or capacity limits are a real constraint in parts of the country.
- PN-EN standards, including PN-EN 62446 for commissioning documentation, govern the technical package.
- Negative or near-zero market prices during sunny midday hours can make export worth almost nothing on some days.
What Poland Actually Changes About Solar Design Software
Net-billing changed the sizing logic. Under the previous opust arrangement, a prosumer exported surplus and withdrew most of it later, which made the grid function as free storage and rewarded generous sizing. Under net-billing, exported energy is valued at a market reference price and imports are paid at the retail price, which is much higher. The gap between those two prices is the entire reason to consume on site, and it makes array sizing a consumption-matching exercise.
Midday prices can collapse. Poland has added enough solar that wholesale prices during sunny midday periods can fall very low, and occasionally negative. Because net-billing settles export against market prices, a system generating a large surplus at exactly the time everyone else does earns very little for it. That is an argument for east-west orientation, for storage, and for load shifting, and it only shows up in hourly modelling.
Connection is an OSD decision. The distribution system operators, principally Tauron, PGE Dystrybucja, Enea Operator, and Energa Operator, issue connection conditions. In parts of the country capacity is constrained and applications are refused or limited. For commercial projects the available connection capacity is an input to the design, not an approval to obtain afterwards.
PN-EN standards govern the package. Polish practice follows the European standards adopted as PN-EN, including PN-EN 62446 for the documentation, testing, and commissioning of PV systems. The commissioning documentation set is specific, and no international design tool emits it.
Support programmes shift. Programmes such as Mój Prąd have supported prosumer uptake, with terms changing between editions. Any incentive figure carried in a design or proposal should be checked against the current edition rather than a cached value.
The Platforms Ranked for Poland
| Platform | Best for | Hourly self-consumption | Editable CAD output | Price per seat per year |
|---|---|---|---|---|
| SurgePV | Commercial layout, SLD, proposal | Yes, 8,760-hour | DXF and DWG | $1,299 to $1,899 |
| PVsyst | Financed and larger commercial | Yes | No | ~$500 |
| HelioScope | Fast commercial rooftop layouts | Yes | DXF only | ~$1,188 |
| Polish market domestic tools | Prosumer workflow | Yes | Limited | Subscription, PLN |
| OpenSolar | Low-volume domestic | Yes | No | $0 plus transaction fees |
| Aurora Solar | Larger commercial-facing teams | Yes | Limited | $1,908 to $3,108 |
| AutoCAD | Final drawing sets | Not applicable | Native | ~$2,030 |
SurgePV covers the commercial case: hourly generation against consumption, string design, single-line diagram, and editable DWG for correction to Polish conventions.
PVsyst is the model Polish banks and independent engineers accept on financed projects, and its hourly output supports net-billing analysis. See PVsyst price and PVsyst alternatives.
HelioScope is the fastest commercial layout tool. See HelioScope pricing.

Match generation to consumption, hour by hour
SurgePV models 8,760 hours against the customer load, tests east-west versus south orientation, and produces the string design, single-line diagram, and DWG export from one license.

What a Polish Design Package Has to Contain
- Layout with module positions and orientation, including any east-west configuration and the rationale for it.
- Single-line diagram with protection, isolation, and metering to the OSD’s connection conditions.
- Connection application to the relevant distribution system operator, with the granted capacity reflected in the design.
- Hourly generation and consumption analysis showing the self-consumption share under net-billing.
- Commissioning documentation consistent with PN-EN 62446, including test results.
- Structural assessment for roof loading, including snow load, which in southern and eastern Poland is significant.
- Equipment documentation with the certifications required.
Item 1 deserves emphasis. Under net-billing, an east-west array that generates less in total but more outside the midday price collapse can outperform a south-facing array on value. That is a modelling result, not a rule of thumb, and it needs hourly data.

What Most Polish Installers Get Wrong
They still size systems as though the opust arrangement applied.
The habit is deeply embedded because it was correct for years: export freely, withdraw later, size generously. Under net-billing that logic inverts, and a system sized to produce a large midday surplus is producing energy at exactly the hours it is worth least. Polish customers who bought oversized systems in the transition period are now the market’s most vocal sceptics, which makes honest sizing a competitive advantage rather than a lost sale.
The second mistake is designing before the connection conditions arrive. Where the OSD limits or refuses capacity, a completed design has to be redone, and the customer has already been quoted.
When Software Is Not the Answer
If the constraint is a commercial roof whose capacity is unknown, or a ground-mount site needing foundation design, that is engineering rather than software.
Our solar civil and structural engineering and STAAD Pro report calculations services cover structural work including snow loading, and solar ground mount design covers layout, foundation, and civil packages for larger sites. See the sample design pack or talk to our team.
Conclusion
- Size to consumption, not to roof area. Net-billing makes self-consumption the payback, and generous sizing no longer pays for itself.
- Test east-west against south with hourly data. Avoiding the midday price collapse can beat maximising total generation.
- Get the connection conditions before finalising the design. Capacity limits are real and redesign is expensive.

FAQ
What is the best solar design software in Poland? SurgePV or PVsyst for commercial work depending on whether you need drawings or a bankable yield report, and a Polish-market tool for prosumer installations. All three need hourly modelling to handle net-billing correctly.
How did net-billing change solar design in Poland? Exported energy is settled at a market reference price rather than swapped against imports at retail value. That makes self-consumption the source of value and turns sizing into a consumption-matching exercise.
Why does orientation matter more under net-billing? Because midday wholesale prices can collapse when Polish solar output peaks. An east-west array generates less overall but more at hours when exported energy is worth more, which can produce a better financial result.
Can the OSD refuse a connection? Yes. Distribution system operators issue connection conditions and in capacity-constrained areas can limit or refuse applications. Obtain the conditions before finalising a commercial design.
What standards govern PV documentation in Poland? Polish practice follows European standards adopted as PN-EN, including PN-EN 62446 for testing, documentation, and commissioning of PV systems.
How much does solar design software cost in Poland? From 0 zl with OpenSolar’s transaction model to roughly 12,400 zl per user per year for a proposal-led stack. Full math is in our solar design software pricing breakdown.
