Obviously there is a lot more than just the batteries. In solar systems, $7k is not a big amount compared to all the other expenses.
I'm assuming you'd minimize your loads, it is silly to size your solar system for a business-as-usual set of loads.
- kondro 11y agoYou definitely could, but that will increase costs even further. You're potentially replacing all your lighting, climate-control, water heating, cleaning (dishes/clothes), cooking & fridge/s to be more energy efficient also. Actual power storage is a reasonably small cost (probably < 20%) in even the solar, power equipment (inverter, switches, controllers, etc), power-storage equation anyway if you want to go completely off-grid. So why does this product make anyone more likely to switch than the existing options?
- marze 11y agoGoing off grid isn't something one does lightly.
- kondro 11y agoWhich was my point :). You seemed to be suggesting you could just buy 2x $3500 batteries and go completely off the grid.
- marze 11y agoObviously you can't go off grid without a solar system, what would charge the batteries? To quote from the original post: "Solar panels are cheap enough you only need batteries to last one night, as you can size the array to operate your loads even on cloudy days."
