Here's some undeniably cool off topic high-tech news for your Friday afternoon pleasure. Tesla Motors officially announced they are creating a spin-off division called Tesla Energy which will sell home batteries for a very affordable price.

For weeks we were teased that Tesla was planning to unveil their home battery product, but the final official announcement kicked off and surprised everyone for being even more affordable than originally thought. The home solution is called the Powerwall and there will be two options available. The cheapest option is a 7k/Wh model for $3,000.00 USD, and the second option is a 10k/Wh model for $3,500.00.

The Powerwall is only a few feet high, a few feet across & 6 inches thick, and it weighs 100kgs (220lbs). The device can be mounted on the outside of your house, or in your garage (or really anywhere you decide in your home). The above price for the device does NOT include the installation, so you will need to hire a professional electrician for that.

There are a couple of things worth noting about the Powerwall. One is that you can add more than one battery to your house if you want to maximize how much energy it can save you based upon your personal electricity usage. The other is that it can be used even if you don't have a solar energy sub-system, yet it can still save you around 25% or more on your electric bills.

The way it handles this feat is by charging itself during non-peak hours (like at 3am for instance), while you then use the battery power during peak hours. The reason this saves you money is that most electric companies charge different rates based upon the time of day you are using electricity. For example, if your power company charges you .10 cents per kWh during peal times, but only .03 cents per kWh during non-peak times, then you end up being charged as if you were using electricity during those non-peak times, netting you a savings.

There's one other handy thing the Powerwall does for users who have multiple electronics and computer devices on all the time. It can act as a built-in home battery backup during power outages. Handy!

The Powerwall begins shipping for installation this summer! For more info, here's a link to Tesla's website: Powerwall Tesla Motors
 
Unfortunately here in Pennsylvania at least near Philadelphia, there are no peak and off peak power rates. All power is charged at the same rate so this would provide absolutely no savings by charging overnight rather than during the day. There used to be a program for a significant power cost difference for off-peak but that program ended for enrollment January, 2014.

Benefit from PECO Smart Time Pricing

Learn how to shift energy – and potentially save money
PECO Smart Time Pricing is a one-year program where customers pay less for the electricity they use during times of the day when the demand for electricity is lower. If you have our new metering technology, you can be among the first to take advantage of this program, which could save you money on your monthly electric bill.

With this program you:
      • Pay the NRG Retail Solutions price of 6.85 cents per kilowatt-hour during off-peak hours and 15.95 cents per kilowatt-hour during peak hours (2p.m. to 6 p.m. – weekdays only, excluding holidays).
      • Save money by running high-usage appliances – such as your washer, dryer and dishwasher – during off-peak hours.
      • Get bill protection: PECO guarantees that if you stay with the program for 12 months and your annual electric generation supply charges are higher than they would have been with PECO’s default service rate, you will receive a check for the difference.
      • No cancellation fee if you choose to leave the program at any time.
Qualifications
This unique program is designed to help you save money. In order to qualify for this program you must:
      • Have the new metering technology installed at your home
      • Not be on the CAP rate
      • Not be a net metering customer
      • Not be on a payment arrangement plan
Enroll
The deadline for enrollment was January 31, 2014.


However, there is one potential added benefit to this that can save you some money although nominal in fact. By having a battery tie to your home power system, it actually provides for current during the cycles of the power that are lost as the signal power switches from positive to negative and then back from negative to positive using AC.

I actually have a device that was sold for exactly that purpose tied into my home, it's a very high powered multi farad capacitor. It remains plugged into the outlet and does nothing other than pull power at the peak of each Hertz, and then dumps it at the dips in each Hertz to provide a more stable and continuous current flow. The benefit is really only felt with motors from what I understand, but if you consider for instance refrigerator compressor motors being one of the largest consumers of power in the home, this device actually allows the compressor motor to run more efficiently and run cooler so it actually reduces the power consumption in kilowatt hours per hour of use and allows the refrigerator to maintain a more stable temperature.
 
We were talking about this today at work. My wifes family actually has a couple of solar panels. I thought about getting them back in service and getting one of these. It would save us a ton of money.
 
One thing REALLY nice about this is that it has it's own power inverter built in so it could alleviate the need to add a full bank of batteries and a large inverter to tie into a solar panel system. I'll bet with some inginuity you could add individual solar panels as you get them, drop them onto the front end of this, tie into the battery bank internally and you're in business.
 
I wonder if the gub'ment would provide a tax credit for this the way they do for solar panels & hybrid/electric vehicles?

S5 tap'n
 
Well, considering the power company is already providing a subsidy through the off-peak rate, and it's not an "alternative" energy source I would bet not.

Ummm, it's Tesla so that's probably they're plan.

Do these have their own inverters? If so that is HUGE! That would be a deal maker for me. I'd love to do a solar system with these. The large cost after the battery is the inverter. Solar panels are cheap now a days and expanding a system as you go would be awesome.

Oops, it says AC inverter not included.
 
As I have solar on my home here in SoCal, this is very interesting, potentially being able to be "off the grid" is huge. I've installed typically lead-acid battery packs for large building temporary backup and they are huge, this size makes it interesting for the home.. I'll have to read more.
 
Hmm, this would be SUPER handy in my RV.
 
In your article you say most power companies offer off peak rates. I'm not so sure that is true. I don't know anyone personally that has different rates day vs night. It may be more of a regional thing.

Most major cities and their surrounding suburbs have peak/off peak charges. It does, however, depend on region size and power plant service areas and loads. A lot of rural places and small metros served by multiple plants are flat rate.

We are moving to a variable rate system in 2016. It has 3 "types" of days (A,B,C) in which each day of the year is one of those three types. Each type of day has a different "peak" and "off-peak" rate, around 27.x cents down to 5.x cents per kwHr. A battery would be AWESOME for me then.

Absolutely. But a small portable gas powered generator still should be part of the standard equipment.

In San Diego, we have 4 tiers and smart meters that can charge more "on peak " times. Thankfully my solar has me first tier...
