As a DIYer, it's all plug and play, so it's incredibly straightforward... you have certified engineers doing your designs, therefore they're gonna be safe electrically and structurally. That to me is a big peace of mind when I did this.

You guys are my guys when it comes to solar. When I got stuck, making a phone call or appointment was one of the huge keys to how well this worked. The confidence and encouragement... it validated that I could do it.
