Although Tesla Motors began its operations from electric cars, but it does not mean that restrict them. The US company just unveiled his latest project, which is the home battery power walls, whose task is to reduce the cost of electricity consumption.
The dimensions of the device are 130 x 85 cm, so it’s a fairly sizable equipment and homeowners will have to save a lot of space for him. The sale of two options will be available with a capacity of 7 kWh and 10 kWh, wherein can also be built with a kind of domestic power plant, because the manufacturer can provide the ability to interconnect up to nine batteries, thereby significantly more energy.
POWERWALL can be charged from a home electrical system, and if so, it raises the question, where are there advantages, since and so we pay for the consumed energy. In some countries, suppliers during the night, offer it at a much lower price and then you can charge the battery in order to then be able to use accumulated during the day race. Additional support will be solar cells, which can also charge us POWERWALL and therefore in theory we use the almost free energy.
Everything looks nice, but a practical man soon ask for price and here ceases to be so beautiful. For POWERWALL version 7 kWh have to pay $ 3,000, while the 10 kWh variant is about $ 500 more expensive, both models are covered by a 10-year manufacturer’s warranty. It is of course the price just the battery itself, this must be added the amount of the cost of installation, the inverter will change us the value of voltage and current, wiring and solar panels, which are optional, and of course an extra cost equipment. And that’s probably another few thousand dollars. The total cost of installing such a battery will probably considerably more than 20 thousand, and that’s considerably reduces the attractiveness of this solution.
POWERWALL Fortunately, you will not need to buy the property, because at current energy costs would be completely counterproductive and would draw up the whole system for several years (unless we would use them to charge an electric car, which is also possible).
Tesla already took care of the necessary agreements, whereby distributors, starting this summer, will lease them to customers, which should slightly reduce the costs of their use.
