We have a client who has a generator but wanted to do part solar as well. We tried to order the IronRidge XR-1000-132A from GoGreenSolar.com; however, the order was canceled because we didn't order enough product. We received an email that stated the following: "We do not ship single quantities of rails. We can only ship rails with our full kit orders." This was our first time using them so we did not know about the quantity requirement, and I think that they should be more clear about their shipping specifications. Overall, it was good, and now we just have to figure out what we are going to do next. If the customer wants a full kit, then we will try another order with GoGreenSolar.com, and if not, we will have to figure out something else!
