Gary is delighted with his Dualsun solar array: before the work was carried out, his monthly electricity bill was around €165, whereas now, with 7 photovoltaic panels, it’s around €40.

A look back at this investment made in 2024 ⬇️

Gary lives in Aix en Provence in a superb 210 m² farmhouse that he completely renovated in 2023.

For him, buying solar panels was a step towards energy autonomy and decarbonisation. What’s more, from a profitability point of view, with energy prices rising and equipment prices falling, it made sense to embark on this project.

Installed in just one day, Gary notes that the project was very easy to carry out: “I had done my research online to find out which panels were the most efficient and the most cost-effective”. The installer also recommended Dualsun panels.

A few weeks after the project was completed, he said: “I can only recommend Dualsun’s partner installer. They were very serious and relevant from the moment I contacted them through to the completion of the work, and even after the work had been completed, with follow-up on the performance of my installation and the improvements I needed to make to improve my self-consumption and become even more independent of the grid.

Thanks to the sound advice of his installer, Gary chose to install 7 Dualsun photovoltaic panels with a power output of 3 kWp on his flat-roofed garage; TopCon 425 panels which have the particularity of being double-sided and which offer a 10% power gain thanks to this bifaciality!

Recycling solar panels

“I’m very pleased with the installation, because there’s even state aid, which together will come to around €2,000, not counting the buy-back of energy that isn’t consumed on my own. It’s a totally worthwhile investment, given the rising price of energy. If you want to have an impact on decarbonisation, be more independent of the grid and have a good experience from A to Z by calling on Dualsun: go for it, you won’t be disappointed!”
