Incentivi per Batterie Domestiche 2026: All Grants at a Glance

Overview: how much incentivo can you get in 2026?

Anyone purchasing a batteria domestica in 2026 can benefit from an attractive package of incentivi and tax advantages. The total financial support can amount to €3,000 or more, depending on the type of system and the municipality where you live. In this article, we discuss all current schemes in detail, so you know exactly what you can claim.

The urgency is significant: the regime di scambio sul posto ends on 1 January 2027. Those who invest now combine maximum incentivi with the remaining scambio sul posto period. This significativamente accelerates the periodo di ammortamento — sometimes from 8 years to 4-5 years.

1. ISDE incentivo: the main national scheme

The Investment Incentivo for Sostenibile Energy (ISDE) is the largest national incentivo scheme for batterie domestiche. In 2026, you can receive a contribution of €500 to €1,500 per sistema di batterie domestiche through the ISDE, depending on capacità and installazione type.

ISDE application procedure

The ISDE is applied for through the RVO (Netherlands Enterprise Agency). You apply for the incentivo after the batteria has been installed. Always keep your invoice and installazione certificate. The application is fully digital via rvo.nl and is tipicamente processed within 8 weeks.

ISDE conditions for batterie domestiche

To qualify for the ISDE, the following conditions apply:

• The batteria must be on the RVO list of approved products (HES products are listed)
• The system must be installed by a installatore certificato (for high-voltage systems)
• The batteria must have a minimum of 1 kWh capacità utilizzabile
• The application must be submitted within 3 months of installazione

Incentivi by system type: comparison table

Available incentivi vary considerevolmente by sistema di batterie domestiche type. Below is an overview of the most popular systems and the corresponding schemes:

2. IVA benefit: 0% on the full installazione

In addition to the ISDE, you benefit from the 0% IVA rate on batterie domestiche combined with pannelli solari. This applies to homeowners with a property less than 10 years old and for combinations with newly installed pannelli solari. The IVA benefit averages €199 to €600 on the batteria itself.

When does 0% IVA apply?

The 0% IVA rate applies when the batteria domestica is installed together with pannelli solari, or when you add the batteria to an existing pannello solare system at a property less than 10 years old. The installatore automatically charges 0% IVA — no separate application is required.

Provincial and municipal incentivi

On top of the national schemes, many provinces and municipalities offer their own incentivi. Noord-Holland, Zuid-Holland and Noord-Brabant have active programmes with contributions of €200 to €750 per nucleo familiare. Always check the incentivo guide for your own municipality or province via the RVO incentivo guide.

Combining incentivi smartly: maximum benefit

It is possible to utilise multiple schemes simultaneously. A smartly combined package can look as follows:

• ISDE incentivo: €600 – €1,100
• 0% IVA benefit: €199 – €520
• Provincial incentivo: €200 – €750
• Municipal scheme: €0 – €500

Energy tax reduction and scambio sul posto: until 2027

As long as the regime di scambio sul posto is still in place (until 1 January 2027), elettricità fed back to the grid still earns you a tax reduction through scambio sul posto. A batteria domestica maximises this benefit because you consume more energia solare yourself instead of feeding it back at a lower rate.

After 2027, the system changes: you will then receive a tariffa di immissione that is in media 50-70% lower than the standard elettricità rate. Those who invest now benefit from both the scambio sul posto advantage and the available incentivi.

Step by step: applying for incentivi

Follow these steps to apply for all incentivi correctly and on time:

• Fase 1: Choose a certified HES system and get advice on eligible products
• Fase 2: Have the batteria installed by a installatore certificato and keep all documentation
• Fase 3: Submit the ISDE application via rvo.nl within 3 months of installazione and apply for provincial/municipal incentivi separately
