Actually, no. Grid-tied Solar Electric Systems generate electricity for your home and route the excess power into the electric utility grid. I don't intend to do that. My main power will be from the grid, and the solar is supplemental and a backup. When I am operating solar, I will open the breaker to HELCO so I am not connected to the grid. I think this will help the permitting since it's the loading study that costs so much and takes so much time. My payback will come from not using HELCO power at different times, and continuing to have power if there is a HELCO power outage. It might be difficult to understand if the view is everything or nothing. My application is in-between, have no desire to be totally off grid power but would like solar to be there, especially when I am on vacation and keeping my security systems powered up.
Those high capacity battery packs could be better than series-parallel battery banks but don't know anything about the cost. Will look into those.
That system was just an example and it definitely uses Chinese cells. Here is another one, similar, 1KW, 4 panels, Chinese cells:

My question was if anybody had any reference cost with a 1KW installation with HIT panels. Chinese panels might not be a bargain for much longer, there is a 30% tariff being applied to them soon.
