Best Solar Design Software Netherlands: 2026 Guide

Dutch residential solar is five months from the largest change in its economics since the salderingsregeling was introduced. Net metering ends on 1 January 2027, confirmed when the Senate approved the termination in December 2024. From that date, exported electricity earns whatever compensation the supplier sets, expected in the range of 5 to 10 cents per kWh, while imported electricity continues to cost retail. Payback periods that run seven to nine years today are projected to move to 12 to 17 years. Every design assumption built on annual netting stops being valid at once, and most solar design software in use in the Netherlands still encodes it. This guide compares the platforms Dutch installers should be moving to now.

Short version. The best solar design software for Dutch installers in 2026 is SurgePV, because the end of the salderingsregeling on 1 January 2027 makes hourly self-consumption the deciding design variable, and SurgePV runs 8,760-hour module-level simulation with battery dispatch against a real load profile. PV*SOL is credible on simulation but desktop-bound. OpenSolar and Aurora encode annual netting logic that expires with the scheme.

The Netherlands has one of the highest rooftop solar penetrations in Europe, built almost entirely on a policy that is about to be withdrawn. That creates an unusual situation for installers: the existing customer base is large and about to become confused, and the sales conversation changes from generation to consumption. For the broader category comparison see our solar design software buyer’s guide and the best solar design software ranking.

What Changes On 1 January 2027

Under the salderingsregeling, exported kWh were netted against imported kWh at full retail value across the billing year. The consequence was that timing did not matter. A household could export all summer, import all winter, and settle the difference at retail rate. Array sizing was a simple function of annual consumption, and the load profile was irrelevant.

From 1 January 2027 the netting disappears. Suppliers set the export compensation, with a government requirement that it be reasonable and not negative. Expectations cluster around 5 to 10 cents per kWh against retail import prices several times higher. Timing becomes the whole game.

There is a second effect already visible. Several suppliers now apply terugleverkosten, feed-in charges levied on customers who export significant volumes. For those customers, export can carry a negative net value even before the scheme ends. A design tool that treats every exported kWh as income is overstating the return today, not just from 2027.

What Dutch Installers Now Need From Design Software

8,760-hour simulation against a real load profile. This is the requirement that replaces everything else. Monthly or annual modelling cannot compute self-consumption, and self-consumption is now the return. The load profile should come from smart meter data where the customer can supply it, since Dutch smart meter penetration is high and half-hourly data is generally available. Our PV yield simulation software guide covers the methodology, and solar shading analysis software covers why module-level resolution matters.

Battery dispatch modelling. The battery case in the Netherlands moves from marginal to central on 1 January 2027, because shifting a kWh from a 6 cent export to a 30 cent avoided import is worth roughly five times the export value. Sizing a battery correctly requires simulating charge and discharge against the actual hourly surplus, not applying a rule of thumb. See our solar plus storage design software comparison.

Orientation reconsidered. Under netting, south-facing maximised annual yield and annual yield was the objective. Without netting, an east-west split flattens the curve and lifts self-consumption, which can return more money from less electricity. Our east-west roof solar design guide covers the trade-off.

NEN 1010 and network operator conditions. NEN 1010 is the Dutch low-voltage installation standard. Connection conditions come from the regional operator, principally Liander, Stedin and Enexis. Grid congestion is now a genuine constraint in parts of the country, and commercial connections in congested regions can face long waits or export restrictions that belong in the design assumptions rather than surfacing after the sale. SurgePV’s Europe compliance library covers the EU-level requirements.

The Six Platforms Dutch Installers Should Evaluate

1. SurgePV, the all-in-one pick

8,760-hour module-level shading and yield, battery dispatch against a real load profile, AI 3D roof modeling from satellite, bankable P50, P75, P90, and white-label proposals with e-signature. The hourly engine is what makes post-salderingsregeling sizing possible. $1,299 to $1,899 per user per year.

2. PV*SOL

Strong simulation with a solid European following, including good self-consumption and battery modelling. Windows desktop, thin proposal layer, so most teams pair it with a separate quoting process. See our PV*SOL alternative comparison.

3. OpenSolar

Free at entry and widely used in Dutch residential. Simplified shading and annual-netting-oriented financial logic, both of which become liabilities after January 2027. Our OpenSolar alternative breakdown covers the limits.

4. Aurora Solar

Deep residential design built for US utility structures. No Dutch tariff logic, no salderingsregeling handling, no terugleverkosten. Difficult to justify here. See our Aurora Solar alternative comparison.

5. PVsyst

The bankable simulation reference for larger Dutch commercial and utility projects, particularly where a lender names it. No proposal layer, no supplier tariff modelling. See our PVsyst alternative review.

6. Zonnerekenaar-style local calculators

Several Dutch tools handle the consumer-facing calculation and supplier tariff comparison well while carrying no real design capability. Useful as a sales aid, not as a design platform.

Netherlands Solar Design Software Comparison

Worked Example: 4.8 kWp Near Utrecht, Before And After 2027

An illustrative calculation using published expectations for post-2027 compensation, not a specific customer project. Inputs: 4.8 kWp, 950 kWh per kWp specific yield, 4,560 kWh generation, 3,400 kWh consumption, import at 30 cents per kWh, post-2027 export compensation at 7 cents per kWh, self-consumption 32% without a battery.

The same system loses 52% of its annual benefit when netting ends. A 5 kWh battery recovers roughly half of what was lost. That is the conversation every Dutch installer will be having through 2026 and 2027, and it cannot be had with a tool that reports annual kWh.

Note the second-order point. Under netting, the battery had almost no financial case, because export already paid retail. From 2027 the battery becomes the primary lever. Installers whose software cannot size one against a real load profile will be quoting batteries by rule of thumb in a market where the sizing decides the payback.

Who Should Choose What

• Choose SurgePV if you want hourly self-consumption, battery dispatch and proposals in one license, and you expect to be selling into the post-2027 market.
• Choose PV*SOL if your work is engineering-led, you value its European simulation reputation, and someone else builds the customer document.
• Choose OpenSolar only for simple residential where entry cost dominates, and plan to revisit before January 2027.
• Choose PVsyst where a lender names it on a large commercial project.
• Avoid Aurora for Dutch residential. It is good software with no relevance to the tariff structure you are selling into.

The Bottom Line

The Netherlands is about to run a natural experiment in what happens when a market built on net metering loses it. Installers who can model the new economics will sell batteries and load shifting. Installers who cannot will quote payback figures that stop being true on 1 January 2027.

• Stop sizing against annual consumption. It was the right method under netting and it is the wrong method without it.
• Collect smart meter load data at the survey. Half-hourly consumption is what makes an accurate post-2027 proposal possible, and Dutch smart meter coverage makes it obtainable.
