Best Solar Software Poland: The Complete 2026 Stack

Polish solar software has to price two different kinds of kilowatt-hour. Since net billing replaced net metering on 1 April 2022, exports settle at the RCEm market reference rate while imports are bought at retail, and the gap between those numbers is the entire design problem. In May 2026 RCEm was 191.37 PLN per MWh, roughly 0.19 PLN per kWh. The month before it was 132.92, the lowest since the mechanism began. So the export side of the equation is both low and volatile, while the self-consumption side is high and stable. A tool that reports one annual generation figure cannot express any of that. This guide covers what the Polish stack has to do.

Short version. The best solar software for a Polish business in 2026 is a stack whose core splits generation into exported and self-consumed energy, prices each correctly, dispatches a battery hourly, and can test the result across an RCEm range. Build the customer document around avoided import, because that is the half of the value that does not move.

This page covers the category as a whole. For the tool-by-tool comparisons see our best solar design software Poland and best solar proposal software Poland guides, and the shading treatment in solar shading analysis software Poland.

The Six Categories, And The Two-Price Problem

What Is Genuinely Poland-Specific

The two-price structure. Under the old net metering arrangement the grid behaved like a bank and the hour of generation barely mattered. Net billing removed that equivalence, and with it the validity of comparing annual generation to annual consumption.

RCEm volatility as a design risk. A 40 percent swing in one month means any configuration justified on export revenue is standing on a moving floor. Configurations justified on displaced retail import are not, because retail prices move slowly by comparison. The practical rule is to test at a low and a high assumption and prefer designs whose ranking is stable, which in most Polish residential cases means higher self-consumption. The robust design and the profitable design converge.

Storage as the primary lever. Moving self-consumption from roughly 35 percent to roughly 75 percent doubles the share of generation earning full retail value without adding a single module. Under net billing that is frequently worth more than adding capacity, which reverses the instinct most installers built under net metering.

Mój Prąd as a configuration output. Support depends on what is installed, so the proposal structure that follows is a comparison of two or three configurations each showing its own support level and payback range, rather than a single quote with a discount applied.

Reduced 8 percent VAT on residential installations, worth showing as a visible line.

Winter output is small, which reinforces the self-consumption argument since winter generation almost entirely lands inside the load.

Where Polish Teams Overbuy And Underbuy

Underbought: split export and self-consumption pricing. The defining gap, and the reason so many Polish quotes describe the wrong value case.

Underbought: battery dispatch simulation. Required to make the argument that matters most.

Underbought: sensitivity testing. A single-figure payback derived from one month’s RCEm will be wrong within a quarter.

Overbought: array capacity. The consequence of annual-totals thinking. Beyond the daytime load curve, each additional kilowatt earns roughly a fifth of what the first one does.

Overbought: seats for viewers. Universal.

The Platforms Polish Businesses Should Evaluate

1. SurgePV, the integrated core

Design and proposals from one record, with split export and self-consumption pricing against RCEm and retail, battery dispatch modelling, RCEm sensitivity testing, Mój Prąd support by configuration and 8,760-hour module-level shading. White-label proposals with e-signature in 9 languages. $1,299 to $1,899 per user per year.

2. PV*SOL

Strong European residential modelling with capable self-consumption and storage tooling, and well established in Polish practice. Desktop-based, net billing applied manually. Our PV*SOL alternative guide covers the trade-offs.

3. PVsyst

The bankable simulation reference, frequently named by lenders on commercial and ground-mount work. No proposal layer and no net billing logic. See our PVsyst alternative review.

4. OpenSolar

Free and quick with a presentable customer document. No net billing logic and limited dispatch modelling. See our OpenSolar alternative comparison.

5. Aurora Solar

Strong residential design built around US net metering, which is the mechanism Poland left in 2022. See our Aurora Solar alternative comparison.

6. Spreadsheets plus a yield tool

Common, and the most likely place a single hard-coded export rate is doing the work of a range.

Poland Solar Software Stack Comparison

Worked Example: 8 kWp Near Kraków, With And Without Storage

An illustrative calculation, not a specific customer project. Inputs: 8 kWp array, roughly 8,000 kWh annual generation, household consumption 5,000 kWh, RCEm assumed at 0.19 PLN per kWh.

The second column generates no more energy than the first. It moves 3,200 kWh a year from the 0.19 PLN column into the retail column, and that transfer is worth several times the export revenue it gives up.

Note what happens to the export line: it falls, and that is the design working correctly. An installer optimising for export revenue would prefer the first column, which is precisely the wrong objective under net billing. A tool that reports export revenue prominently and self-consumption faintly will nudge your team toward the worse design without anyone noticing.

Who Should Choose What

• Choose SurgePV if you need split net billing pricing, battery dispatch and configuration-linked subsidy modelling in one tool.
• Choose PV*SOL if you are desktop-based and value its component depth, accepting manual net billing handling.
• Choose PVsyst where a lender names it on commercial or ground-mount work, paired with separate quoting.
• Quote payback as a range. Single figures derived from one month’s RCEm do not survive a quarter.

After signing, pipeline and follow-up sit in a CRM. QuickEstimate takes the handoff from SurgePV by API.

The Bottom Line

Polish software has to price two kinds of kilowatt-hour, and most prices one.

• Split export from self-consumption. They differ by a factor of several, and an annual generation figure hides the distinction entirely.
• Lead with avoided import. It is the stable half of the value and the half you can still defend in a year.
• Simulate storage with the array. Raising self-consumption is usually worth more than adding modules.
