Incentives for Corporate Photovoltaic Systems 2025: Complete Guide to Lombardy Calls

2025 marks a decisive year for the energy transition of the Lombardy entrepreneurial fabric. The incentives for photovoltaic systems intended for companies represent a strategic opportunity to reduce energy costs and improve the environmental sustainability of production activities. In Lombardy, a region at the forefront of green policies, significant funds have been allocated to support the installation of solar panels and storage systems in corporate realities.

The 2025 incentive landscape is particularly advantageous, with tax deductions, non-repayable grants and subsidized financing that can cover up to 70% of the initial investment. These instruments are part of the broader context of the Regional Energy Plan and European directives for the reduction of CO2 emissions.

Lombardy companies can access various cumulative measures, which include both national incentives, such as those provided for by the PNRR and the FER Decree, and specifically regional ones. The Lombardy Region has in fact strengthened its commitment to clean energy with the introduction of calls dedicated exclusively to companies that invest in medium and large-sized photovoltaic systems.

It is important to emphasize how these incentives do not only represent an immediate economic advantage, but constitute a strategic investment for the future competitiveness of companies. Autonomous energy production allows in fact to drastically reduce bill costs, protecting businesses from the volatility of energy prices and guaranteeing greater energy independence.

Main regional calls for corporate photovoltaics

“Clean Energy for Businesses 2025” Call

The main regional incentive is represented by the call “Clean Energy for Businesses 2025”, which provides for non-repayable grants for the installation of photovoltaic systems in Lombardy SMEs. The call, with a total allocation of 45 million euros, offers a contribution that can reach 50% of eligible expenses, with a maximum of 200,000 euros per beneficiary.

Applications can be submitted starting from April 15, 2025 through the regional platform, with a counter-evaluation procedure until funds are exhausted. The fundamental requirements include:

• Operational headquarters in Lombardy
• Classification as an SME according to EU criteria
• Regularity of social security contributions and absence of insolvency procedures
• System project with a minimum power of 20 kWp

Particularly interesting is the additional 10% premium for companies that choose to also install energy storage systems, allowing for the maximization of self-consumption of the produced energy even in the evening hours or on cloudy days.

Lombardy Energy Efficiency Fund

Another significant opportunity is represented by the Lombardy Energy Efficiency Fund, which provides for subsidized loans (0.5%) for energy efficiency projects that include the installation of photovoltaic systems. The fund, managed by Finlombarda, offers loans covering up to 80% of eligible expenses, with amounts between 50,000 and 1 million euros.

The duration of the financing can extend up to 10 years, with a maximum pre-amortization period of 2 years. To access the fund, it is necessary to present an energy diagnosis certifying the improvement of the company’s energy efficiency following the intervention, with a minimum reduction of 10% in consumption.

National incentives cumulative with regional calls

Lombardy businesses can benefit from a strategic combination between regional and national incentives, thus maximizing the financial support for their photovoltaic projects.

Tax credit for investments in capital goods

The tax credit for investments in capital goods has also been extended to photovoltaic systems classified as capital goods for business activities. For 2025, the credit rate is fixed at 15% for investments up to 2.5 million euros, representing an important opportunity to reduce the actual cost of the system.

Transition 5.0 Bonus

The recent Transition 5.0 Plan includes specific measures for the decarbonization of companies, with a tax credit that can reach 45% for investments involving a significant reduction in energy consumption. Photovoltaic systems fully fall into this category, especially if integrated into a comprehensive corporate energy efficiency plan.

The peculiarity of this incentive is its proportionality to the energy savings achieved: the greater the reduction in consumption, the higher the applicable tax credit rate.

Incentive regulated tariffs of the FER decree

No less important are the incentive tariffs provided by the FER Decree, which guarantee a fixed remuneration for the electricity produced and fed into the grid. For corporate photovoltaic systems with a power exceeding 20 kW, the incentive is disbursed for 20 years and is based on the difference between the incentive tariff and the hourly zonal price of energy.

To access these incentives, it is necessary to participate in the auction procedures or the registers managed by the GSE, with rankings that favor systems built on buildings with asbestos removal or on abandoned industrial areas.

Economic evaluation: investment payback timing

A fundamental aspect in the decision to invest in a photovoltaic system is represented by the investment payback timing. Thanks to the combination of regional and national incentives, payback times for Lombardy companies in 2025 are particularly favorable.

For a medium-sized corporate photovoltaic system (100 kWp) in Lombardy, considering:

• Average installation cost: 1,000 €/kWp
• Average annual production: 1,100 kWh/kWp
• Average self-consumption: 70%
• Electricity price: 0.18 €/kWh

And applying the available incentives:

• Regional non-repayable grant: 50,000 €
• Tax credit: 15,000 €
• Annual bill savings: approximately 13,860 €

The payback time of the investment is reduced to approximately 2.5-3 years, with a return on investment (ROI) that exceeds 300% over the useful life of the system (25-30 years).

These calculations clearly demonstrate how, thanks to the 2025 incentives, the installation of a photovoltaic system represents not only an ecological choice, but also a business opportunity with high profitability.

Procedure and timeline for accessing calls

Accessing regional incentives requires careful planning and compliance with specific timelines. Here are the main phases of the procedure:

FAQ: Frequently Asked Questions

1. Which companies can access regional incentives for photovoltaics in Lombardy? All SMEs with operational headquarters in Lombardy can access regional incentives, regardless of the sector of activity. Large companies (with more than 250 employees and a turnover of more than 50 million euros) are excluded, as they can still access national incentives.

2. Is it possible to combine the various available incentives? Yes, it is possible to combine regional incentives with national ones, respecting the cumulation limits provided for by the individual calls. In particular, the regional non-repayable grant can be combined with the tax credit and the GSE incentive tariffs, allowing financial support to be maximized.

3. What are the average times for processing an incentive application? The average times for processing applications vary based on the type of call. For the “Clean Energy for Businesses” call, being over-the-counter, the outcome is communicated within 60 days from submission. For the Energy Efficiency Fund, times can extend up to 90 days.

4. Is the installation of storage systems mandatory to access incentives? No, the installation of storage systems is not mandatory, but it is strongly encouraged through additional reward premiums. Projects that include storage systems can benefit from a 10% increase in the base contribution in the regional call, besides significantly improving the self-consumption quota of produced energy.

5. How is the optimal power of the system calculated to maximize the benefits of incentives?The optimal power is calculated mainly based on the energy consumption profile of the company, with the aim of maximizing self-consumption. Regional incentives favor systems sized to cover corporate needs rather than for the sale of energy. A detailed analysis of hourly consumption is therefore essential to determine the ideal size.

6. What happens in case of sale or lease of the property on which the incentivized system is installed? In case of sale or lease of the property, the obligations resulting from access to the incentives must be transferred to the new owner or tenant through specific contractual clauses. It is mandatory to communicate to the distributing body any variation relating to the ownership of the property or the activity to avoid the revocation of contributions.
