The energy crisis is a blow for small and medium-sized enterprises, which are saddled with impressive electricity bills.

A situation avoided by a Breton company, which switched to solar energy before inflation.

Today, the investment is far from being regretted.


Emmanuel Macron mentioned it Thursday in St-Nazaire during the inauguration of the country's first offshore wind farm, France must move up a gear on the production of renewable energies, in particular by developing photovoltaics.

Some did not wait and today they do not regret.

This is the case of "Plastiques de l'Estuaire", in Arzal in Morbihan.

A necessity, an investment like any other

"There, we see that the panels produce electricity."

In his Breton company, Thierry Dubois is in awe of a case on which a light flashes.

It's an inverter.

"There is a system that allows for self-consumption," he explains.

"Otherwise, when it's not consumed, it switches to the network, so it's great!"

exclaims the entrepreneur.

Thierry Dubois can indeed congratulate himself: a year ago, he had 160m2 of solar panels installed on the roof of his warehouse.

Today, in the midst of the energy crisis, he is very far from regretting his choice.

It must be said that the initial investment is a winner every time.

"When I discovered this possibility of putting photovoltaic panels on the roof, I said to myself that a priori, I did not need them. But in fact, I realize how necessary it is, at the same title as another investment in the company", he specifies.

"For a little over 30,000 euros of installation, the amortization table shows a profit over twenty years of 90,000 euros, first in self-consumption and then by reselling the electricity", notes Thierry Dubois, very satisfied.

Before the start of this photovoltaic system, this boss paid around 600 euros per month in electricity.

"There are a lot of roofs, industrial buildings that are unused. Install photovoltaic panels!"
