Tesla’s
Powerwall Event: The 12 Most Important Facts
'The issue with existing batteries,' Musk mused, 'is
that they suck.'
"..Tesla just gave us its first look at a new stackable
battery system to store electricity for homes, businesses and the grid.
It’s a product that Tesla says will soon bring in billions in annual revenue.
Here’s what Elon Musk revealed..
1. The home battery version is called the Powerwall. It looks like this:
And it can be stacked, sideways, like this:
2. It’s cheap (but not too cheap). Powerwalls cost $3,500
for a 10-kilowatt-hour version that will allow you to run a handful
of home appliances for a few days in case of an outage. That’s
consistent with the general trajectory of falling battery prices—great for
people who want to live off grid with solar power, but not yet cheap enough to
make economic sense for most grid-connected customers.
3. Notably, that doesn’t include the cost of the
inverter or installation. In a conference call a year ago, Musk gave his first hint of what he wanted the
Powerwall system to look like, including an "integrated bidirectional
inverter, and it’s just plug and play.” The inverter and installation can
more than double the price of a home storage system.
4. It’s thin. The battery is
designed to be hung on a garage wall, or even on an outside wall. It’s 220
pounds but just 7.1 inches deep. That’s two inches deeper than what he’d hoped for, but still pretty
sleek.
5. It ships this summer. Units are
available for pre-order now and come in
several colors.
6. "The issue with existing batteries is that
they suck." That’s Musk’s characteristically colorful take on
the competition. “They’re expensive, they’re unreliable
… stinky."
7. The larger version is called
the Powerpack. Musk's biggest immediate opportunity is in commercial
and utility-scale storage. The Powerpack is “infinitely scalable,” he
said. It consists of 100-kilowatt-hour blocks that can be clustered to meet any
project size.
8. Customers are waiting. Tesla has already been
approached by a utility that wants a 250-megawatt-hour installation, Musk said,
without naming the utility. That's 2,500 Powerpack towers.
Non-utility customers include Wal-Mart, Amazon, and Target.
9. This is what a utility-scale project
looks like:
10. Powerpack costs weren’t provided. It's worth noting that
even before this event, Tesla was already the biggest provider of battery
storage under California’s generous subsidy program for storage projects. The
Powerpack isn't really a new line of products for Musk, just a streamlined one.
11. The event (which started more than an hour after
it was scheduled) was run entirely on batteries. "This entire night,
everything you’re using, is stored sunlight,” Musk told the crowd.
12. The spirit of open source continues. Tesla’s open patent policy has been extended to
both the battery technology and the design of the $5 billion gigafactory
itself..
