To be clear, we are distributing power over about 600m of length, so it has to be high voltage. HVDC is very very dangerous, I would not want it in my house. Not only that, it’s hard to find things that are efficient and work on high voltage DC. Since our batteries are already 60V, our inverters already are very efficient, it’s simply not worth it. Panels are so cheap, it almost doesn’t matter how you are trying to save power, the answer is that it’s almost always cheaper just to buy more panels.
