Photovoltaic Bonus 2026: how to really save and which alternatives to evaluate

Installing a domestic photovoltaic system is today one of the most effective solutions to reduce energy consumption and lower the bill. However, the initial costs are not negligible and, in recent years, a large part of household decisions have been based precisely on the availability of state bonuses.

With the arrival of 2026, many are wondering what incentives will remain active, what percentages will be applied and what to expect for 2027. Understanding the evolving framework is essential for planning conscious investments and evaluating alternative solutions that can guarantee economic stability even in a context of increasingly limited public resources.

Photovoltaic Bonus 2026: what's left and how it works

For 2026, the main incentive tool for domestic photovoltaic installation remains the Home Bonus, confirmed in the budget law. This is the traditional building deduction, already widely used in recent years.

First home deductions

• 50% of expenses incurred
• Maximum ceiling of 96,000 euros
• deduction divided into 10 years
• valid for properties where you have a residence or a real right

The benefit also covers the installation of photovoltaic systems and related support systems.

Deductions for the second home

The benefit remains valid even for properties not used as a residence, but with reduced conditions:

• 36% deduction
• Maximum ceiling of 48,000 euros
• I always recover in 10 years

Although it is a tried and tested measure, the Home Bonus does not always meet the needs of those who want to plan a medium-term investment, especially in a context of possible future changes.

The unconfirmed measures: end of the Superbonus and the limits of the Thermal Account 3.0

The sunset of Superbonus 65%, which in some configurations also included photovoltaic, represents one of the most significant changes. The incentive guaranteed a very high percentage of cost recovery, but in the face of complex technical and bureaucratic procedures and costs often inflated by the supply chain.

A possible alternative may be the Thermal Account 3.0, which offers direct contributions, but only on condition that the intervention is part of a larger project to improve the energy efficiency of the building. The simple installation of a photovoltaic system, aimed at saving electricity, is not enough to access the benefit.

What will change in 2027: reduced rates and weaker deductions

At the moment, the legislation provides for a reduction in deductions starting in 2027, unless there are changes in the parliamentary seat. The main changes will concern:

First house

• deduction that falls from 50% to 36%
• Unchanged spending ceiling at 96,000 euros
• Recovery always in 10 years

Second home

• Deduction that goes from 36% to 30%
• Maximum ceiling of 48,000 euros
• Recovery in 10 years

The decrease in the percentages risks making domestic investment less convenient, especially in the presence of rising costs and construction times that may slip beyond the incentive time window.

Photovoltaic Bonus 2026: what to expect in the medium term

The resources allocated to incentives for domestic photovoltaic seem destined to decrease. The difficulty of predicting future concessions with certainty creates a significant obstacle: planning a renovation requires months of planning and bureaucratic management, and it is not uncommon for a plant to be installed when the originally planned fiscal conditions have already changed.

This disconnect between technical and political times can generate uncertainty and unexpected costs. As a result, many consumers are considering alternative ways to invest in solar energy without being tied solely to the framework of state incentives.

The alternatives: how to invest in photovoltaic with greater stability

Those who want to focus on renewable energy without facing the constraints associated with domestic installation can consider different options.

Funds and ETFs dedicated to solar energy

These are financial instruments that invest in companies in the photovoltaic sector or in indices dedicated to renewable energy. They offer diversification, but they do not allow direct control over the plants nor do they guarantee correlation with real energy production. In addition, they expose the investor to the volatility of the financial markets.

Shared solar parks: a more transparent and tangible model

An alternative and increasingly widespread solution is represented by shared solar parks. In this model, those who invest buy one or more shares of a large photovoltaic system. The revenues derive from the sale of the energy produced, with the possibility of obtaining stable returns in the medium to long term.

Operators such as GridShare, active in the development of solar parks in different areas of Italy, use regulated equity crowdfunding platforms. This offers a double benefit:

1. transparency and complete documentation, useful for accurately evaluating the nature of the project, the technical partners involved and the economic projections
2. stability of the cost of entry, defined at the time of subscription and independent of bonus fluctuations and regulatory changes

Investors are also updated on the status of the works, being able to follow the construction of the plant without having to deal with red tape, installation or maintenance.

Conclusion

The 2026 Photovoltaic Bonus remains a useful opportunity, but the progressive decline in incentives and the uncertainty about future measures make it more complex to plan a domestic plant with predictable economic returns.

In this context, alternative models such as shared solar parks make it possible to invest in photovoltaic with greater stability and with the possibility of obtaining returns linked to real energy production, without depending on fluctuations in tax deductions or on the timing of renovations.
