Switching to "Solar-Ready": A winning strategy for local installers

The French energy renovation market is reaching a decisive turning point. In May 2026, the European EPBD IV directive will make solar energy a technical requirement for new buildings and major renovations. For you, as a local installer, the challenge is no longer just "mounting panels," but ensuring that the building as a whole performs better.

Here is how to transform these new regulations into growth opportunities for your business.

1. "Solar-Ready": An opportunity for the residential and commercial sectors

From 2026, roof designs must integrate photovoltaic capacity. As an expert, you become the key partner in advising homeowners and SMEs on optimizing their rooftops. Anticipating this standard allows your customers to improve their EPC (Energy Performance Certificate) without costly structural work later on.

2. MaPrimeRénov’ 2026: Gaining energy classes

French strategy now prioritizes large-scale renovations. To obtain maximum subsidies, it is often necessary to jump two EPC classes (for example, moving from E to C).

To achieve this, combining high-performance products is the solution:

• PV + Heat Pump: The most effective solution to reduce primary energy consumption.

• Optimized self-consumption: Use smart systems to maximize the use of locally produced energy—a criterion increasingly valued in thermal performance calculations.

3. Choosing the right equipment: Efficiency and Certification

For residential projects and small businesses (below 100 kWp), the priority remains efficiency per square meter and reliability.

At ESTG, we focus on world-leading Tier 1 brands such as Trina Solar or JA Solar. These manufacturers guarantee high yields and rigorous IEC certifications, which are essential for your Consuel files and the long-term security of the installation. For projects under 100 kWp, these panels are the standard for making a building energy-efficient.
