Good product and efficient communication. There was a significant delay in the installation, although it was clearly explained (due to the global maritime transport delays) and no extra cost were involved. There is a lot of information to take on when you install a solar system, so best to do a deep research beforehand to get the right options and the adequate return on investment. With the delay, we had forgotten a good amount of the original information and discussions we had about the project, but the contractors were very qualified and delivered good information as the panels and inverters went on. Very excited to produce electricity from our roof!
