Customer Reviews

Overall rating: 5.0 / 5 from 2 reviews.

I spoke with Billy by phone to confirm the details of my order. Billy was great! He explained the process and confirmed that my setup would work by using panels in series and then parallel. The shipment arrived on schedule and was packed extremely well in a very solid crate. The panels are sturdy and solidly made. I've setup four panels so far and will connect the other four this week. The panels are working well and provide consistent power, even when partially shaded. I am very please with my purchase.
