Yep, we sometimes catch ourselves drewling over a slick Tesla Model S gliding elegantly on the highway but Tesla’s top man Elon Musk is already far beyond the drewling stage. Just this week Musk made its entry in the world beyond automotive with the Tesla Powerwall. The Tesla Powerwall aims at the household that wants to stock its accumulated solar energy inside the home for later usage, instead of transferring it directly on the grid in exchange for a fee.
The Tesla Powerwall comes in two versions: one with a 7 kwh capacity battery (about 3,000 $) and one with a 10 kwh capacity (3,500 $). That doesn’t include the cost of a DC-AC inverter plus professional installation (add a few thousands of dollars to the bill). So yeah, it might be a little hefty for the average household budget that has already spent a few ten-thousands for a decent solar energy capturing system. But hey, this might be the missing link to total freedom and independency, so maybe you’re ready to spent some more ?
Forbes did a complete breakdown of the real life viability of the system. You can check out the conclusion on their site. But, we’re not going to bother you with that. We think it’s a great start for people who want to get rid of the dependency with huge utility companies. However, in order to get some kind of descent return on investment you should be able to go completely off the grid with your existing solar panel system in combination with the Tesla Powerwall. Well, there’s more to look into before drawing any conclusion. We’ll keep it in eyesight for the coming months. The first deliveries of the Tesla Powerwall storage systems should be starting somewhere this summer.
