We’re building a conventional house semi-off-grid, and are trying to decide whether we reasonably need a whole-home generator. We will have solar panels on the roof that should receive sunlight pretty much all day (facing SSW with no obstructions), but will still be hooked up to the grid for backup power and to hopefully sell back some of the power generated by the solar panels. We will hopefully also have batteries for the solar to store some excess power. We cannot be 100% off-grid because of serious health issues, and because we are in a somewhat remote area, we need to be reasonably independent in the event of an emergency.
Our main concern is that we cannot be without our HVAC (will either be a combo of radiant heating and AC or both radiant heating AND cooling, still deciding) or running water from the well for too long due to previously mentioned health issues. Obviously, we’re hoping the solar panels and batteries will be enough to power the entire house (or at least the HVAC and well) in the event of a longterm grid outage, but of course there’s always a chance that the solar won’t be able to keep up if the weather isn’t conducive. We also plan on using high-efficiency appliances and other electronics to further cut down on energy usage.
Considering all this, would a whole-home generator be a reasonable addition? It’s a big expense, but if there’s a reasonable chance the solar might not always keep up when the grid is down, it’s one we’ll have to deal with. Are there other options like a small, easy-to-use generator that could just power the absolute essentials (well, HVAC, and maybe fridge)?
I’d appreciate any insight!
ETA: We will be having everything installed by someone who knows what they’re doing, but obviously we want to have a good understanding of how everything works so we can run and maintain the system. As such, any recommendations for helpful beginner’s guides on solar and electrical systems in general would be really helpful as well!
