Tesla's not-so-secret plan to fill the world's homes with giant batteries could involve leasing them, according to a report from The Guardian. The batteries have apparently already been leased to customers of SolarCity, a renewable energy firm chaired by Tesla CEO Elon Musk, as part of a small pilot program. Customers were asked to finance a $1,500 downpayment followed by $15 monthly payments for 10 years. The puts the overall cost of a 10-year lease at $3,300, or $27.50 per month. According to the report, the cost is further reduced by subsidies from energy companies, who support the idea as it reduces the load on their networks during peak hours.
Why would you want a huge battery in your home? There are a few benefits. The batteries leased to SolarCity customers are able to store energy (up to 15kWh in the trial) from renewable sources locally, rather than feeding it back into the grid when you're not using it. Even if you haven't fitted your roof with solar panels, the batteries can still pull in power from the grid when it costs the least, and then power a home during peak hours, reducing your energy bills considerably. For context, an average american house uses just under 30kWh of energy per day, meaning you could expect to get through the peak hours without much difficulty. The battery packs can also act as an uninterruptible power supply (UPS), keeping your electronics on during power outages.
Tesla has invested heavily in batteries, partnering with Panasonic on a "The Guardian's report), but full details on the plan are expected later this week.
