And ONE and TWO and 70 kWp connected! *

Since 07/12, green electrons have been circulating within CMR...

* in reference to the fact that the project was commissioned on July the 12th, 25 years after the french soccer team won the World Cup... ⚽

Against a backdrop of sharply rising electricity prices, the aim was to make the most of the photovoltaic modules and inverters in stock, some of which had been used on the Hylios prototype. The 70.2 kWp photovoltaic array is installed on the 910m2 roof above the offices. This is a totally self-consumption project, i.e. the electricity produced is consumed entirely on site (no injection into the electrical grid).

The system is connected directly to the building's main LV board and includes:
- 216 RUNDA SOLAR photovoltaic modules (325 Wp each)
- 3 FRONIUS three-phase inverters, 20 kVA each

Implementation of this project required the addition of insulation of sufficient compressibility class to accomodate the aluminium structure supporting the photovoltaic modules, as well as the installation of a new waterproofing membrane. This was necessary regarding the building's age (28 years), so that it could last for the next 25 years. A number of inspections were necessary to validate the feasibility of the project (and reassure the insurer): validation of the existing structure (framework and sheet metal) to support the future installation, electrical and fire risk checks, installation techniques (welding the structure to the new waterproofing).

The panels were oriented East/West to make maximum use of the renovated roof surface.

Annual production is estimated at 91 MWh, representing 30% of the CMR site's consumption in 2022.

The installation is monitored remotely via inverter manufacturer FRONIUS.

Individual self-consumption of energy as part of a CSR approach

Solar self-consumption meets the 3 major challenges of CSR: economic, social and environmental.

Photovoltaic solar power enables you to reduce your company's long-term energy bill. In this way, it optimizes its costs while remaining competitive. By improving consumption management, it is possible to control the impact of inflation.

Solar power reduces dependence on conventional electricity grids. Whether you're renovating an existing building or constructing a positive-energy building, installing photovoltaic panels will enhance the value of your property. At the same time, otping for solar energy means complying with regulations such as the Éco Énergie Tertiaire scheme.

By improving thermal comfort, the installation of a solar power plant optimizes quality of life at work (QWL). This project can also be an opportunity to renovate roofs. By waterproofing and insulating, the company can improve working conditions for its employees.

In its own way, photovoltaics help to reduce air pollution. The sun's rays are an unlimited free, non-polluting resource. In this way, it contributes to the preservation of the environment. As a reminder, in France, 40% of electricity production must be provided by renewable energies (RE) by 2030, compared with 20% in 2022.

What's more, photovoltaic panels produce no noise pollution.
