Since March 1, 2026, the canton of Neuchâtel has supported domestic batteries under conditions with a fixed amount of CHF 800, supplemented by CHF 80 per kWh of capacity. The battery must reach 3 kWh. The supported capacity is capped at 2 kWh per photovoltaic kWp and the amount at 50% of the investment.

Complete approach — step by step

01

Prepare your Pronovo file

For a typical residential installation of less than 100 kWp, the Small Unique Retribution Pronovo is requested after commissioning, with the installation documents. The amount must be confirmed with the Pronovo tariff calculator at the time of the quote. Large projects have different scheduling rules: have the exact case confirmed by the installer before signing.

02

Check the cantonal marker: NE batteries and large PV roofs

Neuchâtel does not publish a cantonal residential PV package of CHF 600/1 200. The confirmed aid is targeted: subsidy for domestic batteries from March 1, 2026 (fixed CHF 800 + CHF 80/kWh, subject to conditions) and aid of CHF 11 000 for large photovoltaic installations on roofs of more than 90 kWp. For a standard villa without battery, the basis remains Pronovo. Before including this item in your budget, check the conditions, schedule and official link: https://www.ne.ch/themes/energie-et-environnement/energie/energie-subventions-et-autres-soutiens.

03

Check municipal aid

Programmes depend on the municipality and available funds. Obtain written confirmation of amounts, timing, limits and combined support for your address before including them in the budget. Contact your municipality or local energy department directly and ask for written confirmation. Do not promise municipal assistance in your calculation until the regulation applicable to your address is confirmed.

04

Check tax treatment

Have your tax service or tax adviser confirm the rules applicable to the year of work, the building and the aid received. A deduction from income is not a refund of the same amount. No flat rate tax savings are included here.

05

Carry out the work with an authorized company

Electrical work must be carried out or supervised by an authorized company. The Pronovo file can be prepared by the owner or a mandated third party; specify by contract who collects the documents and follows the payment.

06

Payment of subsidies

After receipt of the installation report and validation of your file, Pronovo pays the federal subsidy according to its schedule. Targeted cantonal, municipal or Buildings Program aid follows its own deadlines; only deduct them from the final invoice after confirmation.

⚡

Important: check the correct calendar before signing

For small photovoltaic installations, Pronovo is finalized after commissioning. On the other hand, targeted municipal, cantonal, battery or Building Program aid may require an application before work. Have it written in the estimate who prepares each file and when.

FAQ — Solar grants in the canton of Neuchâtel

What is the total grant for an 8 kWp installation in the canton of Neuchâtel ?+

For 8 kWp in the canton of Neuchâtel, the prudent benchmark is PRU to be confirmed + local aid verified. The basis is Pronovo (Estimate to be confirmed via Pronovo tariff calculator). The cantonal part must be read as follows: Battery: CHF 800 + CHF 80/kWh; large PV roofs: CHF 11 000. Municipal or renovation aid must only be added after written confirmation.

Can we combine federal, cantonal and municipal aid?+

Often yes, but only if each help really exists for your case and if its schedule is respected. Pronovo is generally combined with municipal aid or building programs, but certain targeted measures have their own ceilings, exclusions or budgets.

When should you submit the Pronovo application?+

For a small photovoltaic installation of less than 100 kWp, Pronovo indicates that the PRU/KLEIV request is made after completion/commissioning. For large installations and certain devices, the request may be possible or necessary before completion. Have the type of file specified in the quote and keep the commissioning documents.

Is the grant taxable as income?+

Keep aid decisions and invoices. The treatment depends on your situation and the applicable tax rules; have the net basis confirmed by the tax service or your tax adviser. No automatic tax gain is calculated on this page.

How long does application processing take in the canton of Neuchâtel ?+

Pronovo depends on the complete file and the federal calendar. Canton side: Variable depending on measure and cantonal budget. Municipal aid varies greatly: ask your municipality for the deadline before counting the aid in your cash flow.

Are there any specific eligibility requirements for grants?+

Check the Pronovo criteria for capacity, installation type, commissioning and application documents. Electrical work must comply with the low-voltage installation ordinance. Confirm local conditions with the canton: Domestic battery: from March 1, 2026, minimum capacity 3 kWh, ceiling of 2 kWh per kWp PV and 50% of the cost; accommodation and on-site self-consumption required. Large PV roof: installation of more than 90 kWp. See cantonal conditions before signing.
