Daniel is retired from the French education system and owns an east/west-facing house in Rousset (13). On his west-facing roof, he had photovoltaic solar panels installed for the first time in 2010. At the time, solar installations were more expensive, but the government was offering a 50% tax credit and a high feed-in tariff, but without the possibility of self-consumption.
It wasn’t until the installation of a spa and his soaring electricity consumption that he and his wife decided to produce more electricity to compensate.
12 years later and delighted with his first installation, Daniel called on the same company to cover the eastern part of his roof with 8 Dualsun FLASH solar panels. This time, he’s able to consume his own electricity and track it on his app!
“I saved €1,000 over the year on an investment of €9,000, so for me solar is very profitable”
A single day was enough for the 3 installers to finish the job and install a new water heater. With his new self-consumption solar system, Daniel has halved his electricity consumption. They’ve gone from a monthly bill of over €100 to less than €40. When we met him in June, his application showed 70% self-consumption over the day and 52% self-consumption over the year, with the remainder sold back to the grid.
To optimize his self-consumption rate as much as possible, Daniel uses a lot of portable batteries, which he charges during the day and uses at night, for his phone for example. In this way, he tries to consume as much as possible from the sun.
As a mountain climber, he sees the melting glaciers with his own eyes, and wants to do his bit to reduce the impact on the climate.
