Tesla has officially taken the wraps of a new solar powered battery pack for homes dubbed as the Tesla Powerwall. You can register for the Powerwall through the Tesla’s website; it would be available in the summer.
The Tesla Powerwall gets its electrical energy generated from the Sun and then in turn provide electricity to homes. Asides generating charges from Solar panels, it also generates energy from electricity mostly at night when the power rates are at the lowest. It can serves as an emergency back-up electricity supply and for area where are prone to electrical outages (e.g Nigeria) it can serve as an alernative to power supply.
Two model of the Tesla Powerwall are available – a 7KWh daily and a 10KWh weekly cycle; for homes where much more is needed up to Nine more can be installed. It comes with 10 years of guarantee with an option to extend another 10 years. The average powerwall weighs almost 100Kg (200 pounds) and measures about 18cm deep.
The 7KWh daily model which is recommended for daily use costs $3,000 and the 10KWh model which is recommended as a back-up power source costs $3,500 ($350 per KWh). Additional costs would be incurred when Solar panels or AC-DC inverter (about $4000) are purchased; whilst also not forgetting the cost of installation.
PS: The 10KWh model provides around 1000 watts of current for the home for about 10 hours.
