Poland’s prosumer boom was built on a promise that has since been withdrawn. Under the old opust system a customer could export freely and take most of it back later, so the sales pitch was simple and the payback was short. Net-billing ended that, and a generation of Polish homeowners who bought on the old arithmetic are now telling their neighbours the numbers did not hold. Any proposal written today has to work harder, and has to be visibly honest, because the market has learned to be suspicious.
Direct answer. The best solar proposal software in Poland is whichever tool models hourly self-consumption and settles export at a market reference price rather than netting it. Polish-market domestic tools handle the settlement mechanics best for prosumers. SurgePV is the stronger option for commercial work where the proposal also carries the layout and single-line diagram.
TL;DR
- Net-billing settles export at a market reference price. Do not model it as netting against imports.
- Midday market prices can be very low when Polish solar peaks, so surplus generation earns least when there is most of it.
- Self-consumption is the payback. Model it hourly against the household or business load.
- Trust is a live issue after the transition. Showing assumptions on the page is a sales advantage.
- Support programme terms change between editions, so check the current figures rather than using a cached value.
What Poland Actually Changes About Proposal Software
Two different prices. Under net-billing the customer buys at the retail price and is credited for export at a market reference price. Those are very different numbers. A proposal that treats a kilowatt-hour exported as equivalent to one avoided is overstating the return substantially, and that error is exactly what damaged trust during the transition.
Solar cannibalises its own price. As Polish solar capacity has grown, wholesale prices during sunny midday hours have fallen sharply and can approach or go below zero. Because export is settled against market prices, a system that produces a big midday surplus is producing its least valuable energy in bulk. The response in the model is to value export realistically by time of day rather than at an annual average.
Self-consumption is the argument. With a wide gap between retail and market prices, the value of the system is overwhelmingly in the energy the customer uses directly. That makes the load profile the most important input and makes storage, load shifting, and orientation genuine levers rather than upsells.
The market is sceptical. Customers who bought under the old system and saw their payback lengthen are a real presence in the Polish market. A proposal that shows its assumptions and models the settlement mechanism explicitly converts better than one that presents a headline saving, because the buyer is checking.
Programmes change. Support such as Mój Prąd has run in successive editions with differing terms and eligibility. Carrying an incentive figure from a previous edition into a current proposal creates a problem at claim time.

| Spreadsheet over tool output | Bespoke commercial cases | Fully manual | Manual | None | Time |
Polish-market domestic tools handle the net-billing settlement mechanics natively, which is the single most important requirement for prosumer work.
SurgePV fits commercial work, producing hourly generation against load, the string design, the single-line diagram, and the customer document from one model. Technical detail in best solar design software in Poland.
PVsyst supplies the hourly generation series and the bankable report Polish lenders expect. See PVsyst price.

SurgePV models 8,760 hours of generation against the load so self-consumption and export are valued separately, and emits the single-line diagram plus a white-label proposal.

What a Polish Proposal Has to Contain
- System specification with modules, inverter, and kWp.
- Generation forecast with the data source named.
- Self-consumption share modelled hourly and stated explicitly.
- Settlement explanation describing how net-billing values export against a market reference price, not against retail.
- Export value modelled by time of day rather than at an annual average.
- Orientation rationale where an east-west configuration was chosen over south.
- Support programme with the current edition’s terms and eligibility, not a cached figure.
- Battery or load shifting case, if included, modelled separately.
- Assumptions for retail price escalation, market reference price, and degradation.
Item 4 is worth including even though it lengthens the document. Explaining the settlement mechanism in plain language is what separates an installer the customer trusts from one they suspect of repeating the pitch that disappointed their neighbour.

What Most Polish Installers Get Wrong
They quote an average annual export price.
Averaging hides the fact that the customer’s surplus arrives almost entirely during the hours when the market reference price is lowest. A model that credits every exported kilowatt-hour at the annual average overstates export revenue, sometimes considerably. Valuing export by time of day produces a smaller, correct number, and it also produces the argument for storage or east-west orientation, which is a better conversation to be having.
The second mistake is repeating opust-era payback claims. The market remembers, and a proposal quoting a payback that only worked under the old scheme damages credibility before the technical discussion starts.
When Proposal Software Is Not the Constraint
If commercial and agricultural enquiries stall because nobody can produce a layout, a structural assessment for snow loading, or a compliant single-line diagram, that is engineering capacity.
Our solar rooftop detailed engineering design, solar ground mount design, and STAAD Pro report calculations services cover that work. See the sample design pack or talk to our team.
Conclusion
- Value export by time of day. An annual average overstates it because surplus arrives when prices are lowest.
- Explain net-billing in the proposal. In a market burned by the transition, transparency converts.
- Check the current support programme edition. Terms change, and a stale figure becomes a claim problem.

Commercial relationship. Heaven Designs and SurgePV are part of the same group. Treat our recommendation of SurgePV as a vendor making its own case, not an independent verdict. We have tried to describe every other product fairly, and to say plainly where a competitor is the better choice.
Pricing. All prices are indicative, compiled from public sources when this page was written. They vary by tier, region, contract term and exchange rate, and change without notice. Several vendors quote rather than publish, and some price in currencies other than the US dollar, so a converted figure moves with the exchange rate.

FAQ
What is the best solar proposal software in Poland? Polish-market domestic tools for prosumer work, because they handle net-billing settlement natively, and SurgePV for commercial work where the proposal also carries the layout and single-line diagram.
How does net-billing change the proposal? Export is credited at a market reference price while imports are paid at retail. The gap between those prices is what makes self-consumption valuable, and modelling export as netting overstates the return.
Why is midday export worth so little in Poland? Because Polish solar output peaks at the same hours across the whole system, pushing wholesale prices very low and occasionally negative during sunny midday periods.
Should Polish proposals recommend east-west arrays? Sometimes. An east-west configuration generates less in total but shifts output away from the midday price trough, which can improve the financial result. It is a modelling result, not a rule.
How much does solar proposal software cost in Poland? From 0 zl with OpenSolar’s transaction model to roughly 12,400 zl per user per year at Aurora’s higher tiers. Cross-platform math is in our solar design software pricing breakdown.
Can I use the Mój Prąd figure from last year? No. Programme editions differ in amount and eligibility, so use the terms current at the time of the claim.
What about the design software decision separately? Covered in best solar design software in Poland.
