PACA subsidies for the installation of solar thermal panels: what you need to know in 2025

In this year 2025, solar energy continues to position itself as an essential solution for households looking to reduce their energy bills and contribute to the ecological transition. In the Provence-Alpes-Côte d’Azur region, financial aids for the installation of solar panels, whether thermal or photovoltaic, are multiplying to encourage this trend. Whether you are an individual or a professional, it is essential to understand the different subsidies available and how they can alleviate your investments.
From the Eco-PTZ to the energy bonus, including specific regional aids, this article will provide you with all the necessary information to make the right choice and optimize the installation of your solar system. Get ready to dive into the world of solar panels and subsidies that make their installation even more accessible.

The fundamentals of solar panels

The installation of solar panels has become a common practice for several reasons, including the economic and environmental benefits it offers. But before diving into the heart of the subject of subsidies in PACA, it is important to know a bit more about the different types of solar panels.

Types of solar panels

There are mainly two types of solar panels: photovoltaic and thermal.
Photovoltaic panels convert sunlight into electricity. This is the most widespread technology among individuals, allowing not only for self-consumption of electricity but also for selling the surplus to EDF under buyback tariffs. In contrast, solar thermal panels, commonly referred to as solar water heaters, are designed to produce hot sanitary water or for heating using solar energy.

• Photovoltaic panels: Electricity generation.

• Thermal panels: Hot water production.

The characteristics of each type directly influence installation and maintenance, as well as the financial aids you may be eligible for.

Financial aids available for the installation of solar panels in PACA

In 2025, several aids and subsidies are available to candidates looking to install solar systems in the Provence-Alpes-Côte d'Azur region. These aids are implemented to facilitate the energy transition and encourage the use of renewable energy sources. Let’s analyze these mechanisms together.

The Eco-zero interest loan (eco-PTZ)

This scheme allows households to obtain interest-free financing to carry out energy renovation work, including the installation of thermal solar panels. For each installation of thermal panels, an amount of up to €10,000 can be borrowed without any interest charges. If you cover several types of work, this amount can even rise to €30,000.

The photovoltaic self-consumption bonus

Aimed at compensating the initial investment of photovoltaic systems, this bonus is accessible for installations up to 100 kWc. The calculation of the bonus is based on the power of the installation and is spread over five years. The amounts are €0.41/Wc for a 3 kWc installation, decreasing according to capacity, as shown in the table below:

Tax exemption

Solar installations that meet certain criteria may also benefit from an income tax exemption, namely:

• Installation with a power of less than 3 kWc.

• Connecting to the public grid at a maximum of two points.

• No professional activity related to the installation.

Specific aids in the PACA region

Specifically, the Provence-Alpes-Côte d'Azur region offers targeted regional aids to encourage renewable energy projects. Let’s review the main aids for thermal and photovoltaic solar.

Green Deal 06 aid in the Alpes-Maritimes

This aid is established to encourage the installation of solar panels with a subsidy of up to €5,000. The structuring of the aid is based on the national average cost of solar installations, assessed by ADEME.

Sud PV Plus for photovoltaic self-consumption

Another important initiative is Sud PV Plus, which offers financial support for photovoltaic self-consumption installations. The amounts vary from 15% to 30% depending on the type of project and the size of the community. Additionally, a bonus of €10,000 is available if the project includes a thermal solar installation.

Aids for thermal solar panels in PACA

For those primarily interested in thermal systems, several specific schemes also exist.

Durable energy voucher

This aid is essential for those looking to install individual solar water heaters. The maximum amount of this aid can reach €500 for a solar water heater and €1,000 for a combined solar system.

Provence Eco-Rénov of the Bouches-du-Rhône

This aid can cover up to 25% of the total cost of the work related to the installation of solar heaters. For housing in specific areas of Marseille, coverage can even be raised to 50%!
