Your focus is more on residential use and trying to understand how zinc8 can provide a residential solution. And that includes Californians who face not getting power due to fire. But right now zinc8 has a target audience and that audience is providing energy storage for commercial building construction. Yes they can design residential energy storage systems however residential and commercial design require completely different business models. It’s the same reason first solar (a huge solar company) only sells to commercial customers (with the exception of Solar City (now tesla) since they buy in bulk. <br /> <br /> Zinc8 is looking more at 100s of kilowatts to systems on the order of megawatts. This is their target market segment. If they shifted to including residential in their business plan, they would need way more overhead to handle the additional sales, processing, etc for smaller gains. Yes with the right plan it could work but that’s not where their focus is right now. <br /> <br /> The 75 house residential installation is a one off install for demonstrating their design. It’s a way they can show everyone what they can do on a smaller scale before they start going commercial. And I’d imagine they will have other such smaller scale real world demonstrations before they start ramping up commercial production. The zinc8 battery will be the primary power source for the house and will be charged by solar. <br /> <br /> Also something that I should clarify is zin8 could replace diesel generators by being the backup power or they can be the primary power with something else as the backup. It just depends on the design.
