Mr. Houlet and his wife own a wood-frame house that is passive in energy terms. The 12 DualSun solar panels installed on his house allow them to cover more than half of his family’s hot water needs.

“From May to the end of September, the hot water is supplied solely by solar energy. In photovoltaic over the year we cover about half the needs of the house. In the summer, the EDF meter doesn’t run because we’re only on solar panels.”

The main motivation that made them choose solar energy is to reduce their ecological footprint and to use renewable energy as much as possible.

“When I built my house, we had planned to install only thermal solar panels for hot water, but we couldn’t do it because of the budget. A few years later, I heard about DualSun left and right and while doing an internet search I came across this solar innovation that combines both.”

While he initially thought photovoltaics were not very interesting, he then ran simulations on our MyDualSun solar simulator.

“I actually realized that it was interesting. Plus I was pleasantly surprised by the cost, I thought it would be much more expensive, so that made us decide!”

Mr. Houlet likes the 2-in-1: “I find the product very interesting due to the fact that it mixes photovoltaic and domestic hot water. The fact that it is a French product is also good, it avoids buying Chinese products. I liked the DualSun company, they are young dynamic people!”

The solar installation was completed quickly and went well. “DualSun put me in touch with a panel installer trained on their products. This is a security in itself, it avoids falling on a charlatan. It’s a guarantee of seriousness. The installer was very good, very professional, attentive. Everything was done without any worries.”

He chose to sign a contract with EDF in self-consumption with resale of the surplus: “The goal is not to sell, it is well to consume what we produce. Selling the surplus is a small bonus.” After a year and a half of operation he does not hide his enthusiasm: “we realize that we produce more than what was announced on the simulations of MyDualSun. We are really happy, it’s a pleasure!”

“Today I recommend DualSun 100%, for the quality of the product and for the fact that it produces 2 energies at the same time. If we put this on every house in France, we might be able to shut down a few power plants.”

“We don’t use electric, gas or oil heaters. The idea is to benefit from the sun’s rays on sunny days and to use the wood stove as a complement”.
