Working in association with solar panels, this battery should offer three possibilities to their owners: store backup power, minimize peak-time use of utilities’ electricity and get off the commercial power grid entirely. As described on the company’s website, “Powerwall can reduce your power bill by storing electricity when rates are low and powering your home when rates are high.” The Powerwall’s 7 kilowatt-hour model price will be $3,000 and the 10 kwh version will sold for $3,500. That’s not including the installation costs, or costs for an entire solar outfit. Tesla wants to sell its batteries to consumers, businesses, homeowners and utilities. Speculations are made now regarding fact that the price could be not low enough to generate buyer’s attraction. Tesla is taking orders for the batteries now and delivery will begin in three to four months. Tesla Energy is a new division of the company.
