Through 31 December 2026, the Dutch net metering scheme (salderingsregeling) remains in full effect. The electricity you export can still be offset against the electricity you import over the year, up to the amount eligible for net metering.
From 1 January 2027, the scheme ends by law—no phase-out, no transition period. The Dutch Senate passed the Termination of Net Metering Act (Wet beëindiging salderingsregeling, 36.611) in December 2024.
After that, exported surplus earns only a feed-in compensation. Until 2030, this compensation must be at least 50% of the supplier’s electricity rate excluding taxes and levies. In most cases, that will be considerably lower than the total price you pay to import electricity from the grid.
That difference—between what you receive for exported solar power and what you pay for electricity later—is the gap home storage helps you close.

| Storage comparison | During the day | In the evening | What it means |
|---|---|---|---|
| Without storage after 2027 | Export surplus to the grid | Buy electricity from the grid | Export for less, import later for more |
| With home storage | Store surplus solar power | Use your stored solar energy first | Use more of your own energy and buy less from the grid |
The Dutch electricity grid is under growing pressure. On sunny afternoons, many homes can export solar power at the same time. In some areas, this can put extra pressure on the local grid and cause voltage to rise.
If local voltage becomes too high, solar inverters may temporarily limit or stop feeding electricity into the grid to protect the system.
Surplus solar energy can be stored in your battery instead of being exported immediately, helping reduce peak solar exports.
More surplus energy must be exported, increasing your exposure to grid limitations when local demand is low.
The Bottom Line
Net metering is ending. Exported solar power will generally be worth less than the electricity you buy from the grid. The grid is under growing pressure.
Together, these changes make home storage more valuable than ever.
The question is no longer just how much solar power you generate, but how much of it you can keep and use yourself.

No need to replace your existing microinverter. SigenMate integrates directly with your current solar setup, making it easy to add energy storage without changing your existing equipment.

Up to 4,000 W solar input and 4 independent MPPTs help maximise generation across panels with different orientations or partial shade. Exclusive PV Clipping Detection helps prevent excess solar from going to waste by alerting you to free up battery capacity before reaching the grid export limit.

Sigen AI optimises charging and discharging using electricity prices, weather forecasts and household energy use. If the cloud is temporarily unavailable, core energy management continues locally using your saved strategies.

Start with 2.68 kWh and add more capacity as your household energy needs grow. The main unit and expansion batteries stack together in a modular design, making the system easy to expand without replacing your existing equipment.

With 0 ms switchover and 1,400 W of off-grid backup power, SigenMate keeps essential devices such as your fridge, router and computer running without interruption when the grid goes down.

Securely mount the solar panels on a balcony railing, terrace, roof or the ground, depending on the installation location, and firmly tighten all mounting screws.

Connect the solar panels directly to the SigenMate 2700 Ultra. If you already use a third-party microinverter, you can connect your existing system to the SigenMate 2700 Ultra and easily add energy storage. A clear click confirms that the connector is securely locked in place.

Simply plug the output cable into a suitable household socket—and you’re ready to go. You can now use the solar power you generate directly in your home.
Under Dutch tax rules, a 0% VAT rate may apply to qualifying solar panels installed on or near residential properties. Eligibility depends on the product and installation conditions. Home batteries are generally subject to 21% VAT, but eligible owners may be able to reclaim all or part of the VAT on the purchase and installation if the applicable conditions are met.
There is currently no general national purchase subsidy for residential solar panels or home batteries in the Netherlands. However, some municipalities offer local subsidies, sustainability loans or other financing options. Check the latest schemes with the RVO and your municipality.
Tenants should obtain written permission from their landlord before installing solar panels. If you live in an apartment, approval from the Owners’ Association (VvE) may also be required, particularly when shared areas, the façade or roof are involved.
Always check the applicable rules with your landlord or VvE before installation. As a portable system, SigenMate can be disconnected and taken with you when you move.
Register your solar and storage system with your grid operator before commissioning, using Energieleveren.nl or the registration channel specified by your grid operator.
Have the technical details of your solar panels, inverter and battery ready. Registration requirements and processing times may vary, so check the procedure with your grid operator in advance.
The Dutch net metering scheme remains in effect until 31 December 2026 and ends by law on 1 January 2027.
After that, exported solar electricity will receive a feed-in compensation instead of being offset against electricity imported from the grid. Storing more of your daytime solar energy for evening use can therefore help you retain more of its value.
From 1 January 2027, the electricity you export to the grid will no longer be offset against the electricity you import. Instead, you will receive a feed-in compensation, which will generally be lower than the retail price you pay for electricity from the grid.
A home battery stores surplus solar power generated during the day so you can use more of it in the evening and at night. Actual savings depend on your energy contract, electricity prices, feed-in compensation, system efficiency and household energy use.
Yes. SigenMate is compatible with third-party plug-in microinverters and can be added to your existing solar setup without replacing your current equipment. This makes it easy to add energy storage while keeping your existing solar system.
Yes. When the backup function is enabled, SigenMate switches to off-grid operation with a 0 ms switchover and provides up to 1,400 W of backup output from a single unit.

Up to three systems can be connected in parallel, increasing the total storage capacity to as much as 56.4 kWh.
Registration requirements depend on your grid operator and system configuration. Solar generation and home battery systems may need to be registered before commissioning.
Check the applicable process with your grid operator—such as Liander, Stedin or Enexis—and have the specifications of your solar panels, inverter and battery ready.
Yes. If you rent your home, obtain permission from your landlord before mounting solar panels or making changes to the property. If you live in an apartment, approval from the Owners’ Association (VvE) may also be required.
Always confirm the applicable building, rental and VvE requirements before installation.
A home battery stores solar electricity that you do not immediately use during the day and makes it available later, such as in the evening or at night.
This helps increase your solar self-consumption, reduce the amount of electricity you buy from the grid and, when backup mode is enabled, keep compatible devices running during an outage.
The SigenMate 2700 Ultra measures 460 × 275 × 225 mm and weighs approximately 29 kg. Each SigenMate BAT 2700 expansion battery measures 460 × 215 × 225 mm and weighs approximately 25 kg.
Its compact footprint is approximately 0.10 m². With an IP66 protection rating, the system is suitable for indoor or outdoor installation when installed in accordance with the product manual.
Yes. Solar panels continue to generate electricity from diffuse daylight on cloudy days, although their output will be lower than in direct sunlight.
SigenMate features four independent MPPT trackers, helping optimise solar generation when panels have different orientations or experience different sunlight conditions.
Yes. SigenMate’s Plug & Play and modular design makes it easier to disconnect, relocate and reinstall than a permanently integrated storage system.
If you rent your home, coordinate both the original installation and removal with your landlord.
After moving, check the installation and registration requirements that apply at your new address before reconnecting the system.

Add smart storage to your existing solar system—with Plug & Play setup, Sigen AI and 1,400 W backup power.
