I have a customer that was wanting to install a 30kw system on his home that is 10,000 square feet or so with an indoor pool. This system has been sized to only cover the usage of the home as the utility co. only does credits (monthly true-up) at avoided cost. The engineer at the utility co told him that "he could only do a 10kw system size because his home is at the end of the line". "Because the house was at the end of the line, any power produced but not used during the day would have to be "pushed" back through the line they came from. They max they would allow was 10KW so it wouldn't damage other houses". That was from the engineer. Also, said something about a lot of solar being in the area because of a neighbors solar panels.
This is the first time I have ever came across something like this. Figuring a 30kw system might be feeding back 125A (probably 100A with inverters at a 1.2 DC/AC ratio) I do not understand how this could be an issue for the utility co? What am I missing? I have had systems limited by the utility co. in other states (KS) but never one in Missouri in my 12 years of being in the solar industry. I assume this would be something that would be in the statewide net metering laws/policys I might need to check in to?
