| This is being mounted on an RV, which is explicitly off-grid, and would only be intermittently connected at best. In my municipality they only do power buy-back from larger generators. Also most of it isn't going through an inverter, I'm using direct DC-DC, which is much more power efficient for what I'm doing. So that means more cost for inverters, which I'd consider paying even if at the scale I'm working at it would take years for the equipment to pay for itself, but... You can't simply tie an inverter into the grid and sell back to the power company, as that could mean that during repairs lines they thought had no power were energized by some residential customer. You need special hardware that the power company can shut down remotely, and that's only available for larger customers. Also I'm not sure if the price I'd be getting for that power would actually offset the monthly connection fee, making connecting to the grid and selling back extra power very likely cost more than just wasting the power, which is unfortunate. So unfortunately grid-buyback that isn't really an option for me. Which is why I'm looking at other options. I like the wood pellet one, in an ideal world I'd be able to do some kind of carbon capture or something, but I'm not seeing any good power-to-gas tech right now. |
