%s/electric cars/personal electric vehicles/g. Cars are too inefficient. Right now our "power goes out for two weeks" contingency is the solar-paneled RV and a Honda generator. Neither the panels nor the generator can charge the car in a reasonable amount of time. The RV solar panels can charge the scooter (or electric bicycles) in the same amount of time as house AC (big inverter in the RV). It won't get you to the mountains to your remote cabin (that's what the RV is for <g>), but it's enough to get around town if need be, and can do so indefinitely.
On a related note, as I've researched solar panels for the house, it came as a surprise to me that by default grid-tied solar won't keep the lights on when the power goes out (nothing to sync to). So if one goes that route, don't forget the batteries and inverter.
- oceanplexian 7y agoThe electric car is useful because in the event of a power outage, a decent one will have a 60KWH+ battery. Assuming it's even partially charged, that's enough energy to power personal electronics for weeks. You could probably even power a fridge, TV, and some basic household equipment for a week if you had a decent inverter. On the other note, if you get grid tied solar you can use them if the power is down, but you need to buy an SMA inverter with secure power supply. The inverter will give you an outlet that will work if the grid is down, even without a battery system.
- mikestew 7y agoYou're just doing a global search-and-replace and replacing with "big ass battery". :-) I take your point, but I was referring to transportation. As you point out, ride the scooter and use that big ass battery in the car for something else.
- lutorm 7y agoby default grid-tied solar won't keep the lights on when the power goes out (nothing to sync to). Indeed, but some inverters have emergency outlets where they can supply power on a dedicated circuit as long as the panel output is enough. The amount of power is limited and it can't sustain any surges so it can't run e.g. motors, but having 1500W is tons better than having 0... I've verified that my big-ass UPS that I use for the computer can run the refrigerator and be charged from this outlet.
