It's been a little over a month since the Energia team installed photovoltaic panels with a battery for nighttime use. We are very satisfied with this system. In July, we imported less than 2% of our electricity, and there is still room for improvement. I agree with the other reviews: the whole team is very friendly and professional.
Thanks to Loic, Florent, and Julien, who came to our house and we are delighted! They were very friendly, cheerful, and patient in explaining the process to us. I recommend and thank Energia for this service.
