Italy: 2027 Photovoltaic Bonus: 40% Contribution and Deductions Up to 50%

Key facts

  • Article 79 of the 2027 Budget Law draft introduces a capital grant of up to 40 percent for new photovoltaic systems with a nominal capacity not exceeding 1 megawatt
  • The 2027 budget measures offer tax deductions of either 50 percent or 36 percent for solar panel installations, depending on the specific property and taxpayer criteria
  • The standard spending cap for the tax deduction is set at 96,000 euros per real estate unit, with the deduction spread over 10 equal annual installments
  • The tax deduction is not an immediate cash refund but a reduction in taxes owed when filing the annual income tax return, linked to building renovation projects

The 2027 solar photovoltaic bonus introduces a new incentive structure, offering a 40% contribution for the installation of solar panels and detailing how tax deductions will evolve. The following analysis covers the specific amounts, potential savings, and the rules regarding the cumulation of these benefits.

The 2027 budget measures introduce the photovoltaic bonus as a key provision, offering a contribution of up to 40% of eligible expenses for the installation of solar panels on residential properties. In addition to this incentive, tax deductions of either 50% or 36% are available, depending on the specific property and the taxpayer’s qualifying criteria. The two support mechanisms operate under distinct access conditions.

The following details outline the provisions of the 2027 photovoltaic bonus, identify the eligible beneficiaries, and assess the potential savings associated with installing solar panels.

2027 Residential Solar Incentive: What the Budget Measure Provides

Article 79 of the 2027 Budget Law draft introduces a capital grant of up to 40 percent for the installation of new photovoltaic systems with a nominal capacity not exceeding 1 megawatt (MW). The funding is intended to support the generation of electricity from renewable sources.

A total of 1.2 billion euros has been allocated over three years for this measure, earmarked for financing installations with a maximum aggregate capacity of 3 gigawatts. The administration of the grant has been assigned to the Gestore dei Servizi Energetici (GSE).

Who is eligible for the 40% subsidy

The new incentive is not automatically granted to individuals installing photovoltaic panels. To qualify for the funding, applicants must meet the specific requirements established under the FER X mechanism. The 1 MW power limit encompasses facilities of varying scales, ranging from small-scale installations to those serving productive activities.

Individuals may also access the FER X under certain conditions, although this does not imply that all residential systems are eligible for the contribution. The eligibility criteria, application procedures, and oversight protocols will be detailed in a specific implementing decree, which is required to be adopted within 120 days of the entry into force of the Budget Law.

Photovoltaic tax credits at 50% and 36%

For homeowners looking to install solar panels, the upcoming budget law maintains the tax deductions tied to building renovation projects. Article 4 of the bill outlines two distinct tax rates.

The standard spending cap is set at 96,000 euros per real estate unit, with the deduction spread over 10 equal annual installments. Consequently, this is not an immediate cash refund, but rather a reduction in the taxes owed when filing the annual income tax return.

How much can be saved by installing solar panels

A residential solar photovoltaic system with an eligible expenditure of 10,000 euros would yield a theoretical tax benefit of 5,000 euros under the 50% deduction scheme. This amount is distributed over ten annual installments of 500 euros each. Under the 36% deduction rate, the total benefit decreases to 3,600 euros, payable in ten installments of 360 euros.

These figures illustrate the tax advantage within the specific example, subject to the limits of the tax liability and the conditions set by law. This fiscal benefit can be complemented by savings on electricity bills, which depend on the system's energy production and the volume of power consumed directly within the home.

Can the 2027 solar tax incentive be combined with the tax deduction?

The 40% grant and the 50% tax deduction are not two discounts that can be automatically combined. The former is a capital financing linked to the FER X mechanism, while the latter is a tax deduction provided for specific building works.

Any compatibility between the two incentives depends on the implementing rules of the new grant (updates on which can be found in the economy section of donnesulweb). Anyone looking to install a system must therefore verify which incentive they can actually use, without assuming a total benefit of 90%.

When to apply for the 2027 solar power bonus

The new 40% grant is not yet operational. The draft budget law must complete its parliamentary process, and the specific access procedures will be defined subsequently. Consequently, it is currently impossible to determine when applications can be submitted or which investments are eligible.

In contrast, the fiscal measures intervene on an existing system of tax incentives. Before incurring any expenses, it is necessary to verify the property’s eligibility requirements, the required documentation, and the mandated payment methods.

The 2027 solar bonus thus provides two avenues for savings. The first is a grant covering up to 40% of the costs incurred for installing solar panels in a home. The second consists of tax deductions that can be recovered through the 7e30 mechanism.

Pvola take

This dual incentive structure significantly lowers the upfront capital barrier for residential solar projects by combining a direct 40 percent grant with long-term tax relief. Developers and installers should prioritize projects that qualify for the higher 50 percent deduction tier, as the combination of immediate grant and deferred tax savings creates a stronger financial case for homeowners. The 10-year installment period for the deduction requires careful cash flow planning, but the total support remains substantial for eligible properties under the 1 MW capacity limit.
