My solar panel installation

I contacted y solar after coming across them when searching for local installers in my area, having made the call I arranged for a survey a few days later.
After having our survey done I placed my order as I was more impressed with their equipment than the other quotes I had, i chose to get 12 panels that are 330 watts, that all but gave me a 4kw system compared to the other companies where I could only get a 3kw system.
The installers were also very good, I am very happy with my choice of companies.
