The Tesla Powerwall promises that it will power your home or business in a more efficient mane and can do so entirely by getting of your traditional power grid. The institute for energy research has recently looked into the numbers and found that it would take you nearly 38 years to for the Powerwall to pay for itself in your home or business. Powerwall hooked up with the proper solar power connectors. It’ll take you something more like 31 years for Tesla’s Powerwall to break even IER reports.
This the institute is assuming the cost is $7,340 to buy and install the powerwall and enable the DC to AV inverter to be put in thanks to their subsidiary solar city. It calculates that the savings over time using peak rating pricing which is a generous look would say that the powerwall nets about $0.53 in savings per day. That doesn’t sound like very much pesto, but consider that this is considering the figures today, they will inevitably get better, and much better at that. Moreover, you’re in it for the long haul with your home and any savings should be meet with open arms. Finally you’re off the grid and have the means to be self sufficient with your power. It would take nearly forty years for a Powerwall to pay for itself, which is almost four times the warranty period. It is highly unlikely that it would even last that long,” IER’s Chris Warren told
“The report done by the Institute for Energy Research is elementary, at best, and completely misses the value of the Powerwall. For one, IER assumes a fabricated rate structure without citing any source. Transparently, if a consumer were to have a rate structure defined in the article, then the payback calculation is indeed correct. However, very few people with this sort of rate structure are interested in Powerwall for financial reasons. They are interested for energy independence, backup security, environmental reasons and tech early adoption, none of which are taken into account.”
This is being met with some skepticism and many believe that the number was influenced by interested that do not want the solar boom to take off with the speed and inevitability that it currently is. If the Tesla Powerwall system can take off they will again be in a market where they are standing alone, and we need to consider if any other american company can step up to the Elon Musk empire.
In December the Vermont company green mountain power sold Tesla’s power wall to residents for a staggering $6,500. Users can share the battery with GMP and get up to $31.76 credit on their monthly electrical bill or even a cool $37.50 per month for the powerwall at no money down. This model of the no money down solar panel is going to be an interesting development in the leap into households. Solar city is already offering free installation for anyone, and this concentration is needed if they want it to take off with the speed only fitting of Elon Musk.
