Dutch homeowners navigating Netherlands solar incentives in 2026 face a policy landscape defined by a firm deadline rather than the gradual taper many expected. The longstanding net metering system — known as 'saldering' — will be abolished on 1 January 2027, following a Dutch Senate vote in December 2024 that scrapped an earlier phased-reduction plan. Until that date, full net metering applies. Understanding what changes from 2027, and how to position a new installation to thrive without it, is now the central question for any Dutch homeowner considering solar.
Saldering: Full Net Metering Until 1 January 2027
Under saldering, exported solar electricity is offset against grid imports on a 1-for-1 basis on your annual bill. For most Dutch households, this has made solar financially compelling: surplus generated in summer effectively pays for grid imports in winter at the full retail price. The original plan to taper this offset gradually from 2025 onwards was voted down; instead, the full benefit remains until the end of 2026. From 1 January 2027, suppliers will set their own export compensation rates, with a government requirement for 'reasonable' compensation but no guaranteed retail-price equivalence. This transition makes self-consumption optimisation and battery storage considerably more valuable for systems installed now.

ISDE: Subsidies for Heat Pumps and Solar Thermal
The ISDE (Investeringssubsidie Duurzame Energie en Energiebesparing) is the Netherlands' main investment subsidy for sustainable energy equipment in 2026. It supports heat pumps and solar thermal collectors — but does not cover standalone home batteries. The RVO (Netherlands Enterprise Agency) has confirmed that home batteries only qualify for ISDE support when installed as part of a heat pump or solar thermal combination; a battery added solely alongside solar panels does not attract a national subsidy in 2026. Homeowners should verify current rates on rvo.nl before applying, as ISDE budgets and eligible product lists are updated annually.
For air-to-water heat pumps, the 2026 ISDE provides a base amount of €1,250 plus €225 per kW of heating capacity above 1 kW, with an additional bonus for A+++ label systems. This makes a heat pump + solar combination financially attractive even without a battery subsidy.
What Replaces the Saldering Benefit from 2027?
The post-2027 landscape will reward homes that maximise self-consumption. Three strategies are gaining traction among Dutch installers and energy advisers:
- Battery storage: storing midday generation for evening use avoids the need to export at a potentially lower rate.
- Dynamic tariffs: providers such as Tibber, Frank Energie, and ANWB Energie offer hour-by-hour pricing linked to wholesale markets, allowing smart dispatch of stored solar during high-price periods.
- Smart EV charging: routing surplus solar into an EV battery via a smart charger replicates much of the economic benefit of saldering within the household boundary.
VAT Relief and Practical Support
The Netherlands applies a 0% VAT rate on solar panel supply and installation for residential properties, a measure introduced in 2023 and still in place for 2026. This materially reduces the upfront cost of a new system. The SDE++ scheme continues to support larger commercial and utility solar projects, but residential systems below around 15 kWp typically do not qualify and benefit instead from saldering and ISDE.
Sizing and Payback in 2026
Given that full saldering runs to the end of 2026, a system commissioned before year-end can benefit from at least one full year of retail-rate netting before the policy change. The Netherlands added approximately 2.08 GW of solar in 2025, and cumulative capacity reached around 29.7 GW — a sign that Dutch installer networks are mature and competitive. Typical residential payback for a well-sized system currently runs in the range of five to seven years, though this extends post-2027 for households without battery storage.
Key Takeaways
- Saldering (full net metering) remains in place until 1 January 2027 — the gradual taper plan was scrapped by the Dutch Senate in December 2024.
- No national standalone battery subsidy exists in 2026; ISDE covers batteries only in combination with a heat pump or solar thermal system.
- From 2027, export compensation will be set by suppliers; maximising self-consumption becomes the priority strategy.
- Dynamic tariffs from providers such as Tibber and Frank Energie are a practical post-2027 complement to rooftop solar.
- 0% VAT on residential solar panels and installation remains in place for 2026.
