Solar PV and storage: how much is the regional grant really worth?
Individuals and apartment buildings: grants up to 40%. Applications from 16 November 2026 at 10:00 to 30 September 2027 at 12:00, subject to available funds.
Scheduled opening: 16 November 2026 at 10:00. Deadline: 30 September 2027 at 12:00, subject to available funds. As of 4 November, the regional page has not yet published the platform link.
The notice requires at least 3 kW of additional installed capacity, including upgrades. VAT is eligible. Work must be completed before applying; the notice’s other conditions and exclusions apply.
A grant can improve an installation's financial balance. But making a sound decision requires two checks: how much support is available and how well the system fits the consumption of the home or condominium.
1. Who can apply for the grant
The annex to Regional Executive Decision 1165/2026 allows applications from private individuals who have the dwelling served at their disposal. This text does not expressly restrict eligibility to a main home: requirements and documentation must be checked in the notice.
For condominiums, the application is submitted by the duly appointed manager, specifically authorised by the owners' meeting, exclusively for work serving communal areas. In buildings with several units held by two or more private individuals and no manager, where provided for, a private individual expressly delegated by the other co-owners may act.
The measure described here is not the business grant scheme. The decision leaves the rules for legal entities to a subsequent measure.
2. Which measures are covered
New photovoltaic systems or capacity increases to existing ones, potentially combined with storage. Systems serving homes in areas not reached by the grid, with no connection points at all, are also covered. Each application concerns one installation and, where applicable, one associated storage system.
A battery alone on an existing installation should not be assumed to be eligible: the text describes new installations and capacity increases with optional storage. This case requires clarification in the notice or from the competent authority.
3. The 40% rate and the three limits to apply
The grant is capped at 40% of eligible expenditure actually incurred. A unit cap and an overall cap also apply.
| Measure | Unit cap | Maximum eligible expenditure | Maximum grant |
|---|---|---|---|
| Solar PV | €1,500/kW | €30,000 | €12,000 |
| Storage | €600/kWh | €12,000 | €4,800 |
The theoretical overall maximum is €16,800, achievable only when both components meet their respective limits and requirements. This amount is not automatically awarded to every installation.
4. An example: 6 kW of solar PV and 10 kWh of storage
- Solar PV: 6 × 1,500 = €9,000 in maximum eligible expenditure; grant up to €3,600.
- Battery: 10 × 600 = €6,000 in maximum eligible expenditure; grant up to €2,400.
- Total: up to €6,000, provided that the actual eligible expenditure reaches these amounts.
A higher quotation does not increase those caps; lower eligible expenditure reduces the grant. This is a worked example, not a NOAH quotation or a promise of funding.
5. Which costs are eligible, and from when
Expenditure must be incurred from 9 October 2026. Eligible costs include the supply and installation of photovoltaic systems, strictly necessary building work, mounting structures, components, inverters, electrical components and grid connection. For storage, they include supply, installation and the associated work and components listed in the annex.
The notice includes VAT. For other costs, including professional fees, check the eligible expense list before calculating the grant.
6. When to submit the application
The grant is awarded on the basis of documentation demonstrating full implementation and completion of the work. This text does not provide for reserving funding on the basis of a quotation alone. Expenditure is checked during the assessment of the application.
Submission will be through the regional platform using SPID, CIE or CNS, exclusively by the applicant. Applications will be assessed and funded in chronological order until resources are exhausted. The procedure ends within 90 days of its commencement, excluding suspensions: this is not a guaranteed payment deadline.
The customer must therefore consider the upfront expenditure and the availability of funds. The decision also provides for partial grants, with 15 days to accept them, and for applications initially unfunded to move forward if further funding becomes available.
7. Can it be combined with other incentives?
Section 5.3 allows combination with other public grants or financing, up to the eligible expenditure and subject to the conditions of each set of rules. This sentence does not establish that the grant, tax relief and renewable energy community incentives can automatically be combined. Each individual combination must be checked separately.
8. NOAH's assessment: start with consumption
The grant is useful support. However, the system and battery should be sized by considering consumption at different times, orientation and shading, expected generation and self-consumption potential. In condominiums, the loads in communal areas must be considered: lifts, lighting and centralised systems.
A larger battery does not automatically produce a better result. It is necessary to understand how much solar energy remains available to charge it and how much is used when the sun is not generating.
Do you own a home or manage a condominium in the Aosta Valley? Bring NOAH your bills, the building's location and information on the existing system. We can prepare an initial assessment and compare solutions against the scheme's requirements.
