It’s been interesting to read and watch how corporate media, industry experts and financial analysts digest Tesla Energy’s battery storage solutions over the last seven days. Numerous media outlets are poking at Tesla’s business premise of a 7 and 10 kWH residential battery packs for your home, as they should be.
Here’s a very even-handed take by Dan Steigert, an energy professional, on the 7 kWh daily battery:
If you are getting this out of the battery every day for 10 years the price drops to $0.12/kWhr-cycle, again neglecting installation and inverter price. If this is truly the spec, this is an exceptional number. It is still more expensive than a genset—fossil fuel generator—because the genset can run @ $200/kW, and this is $1500/kW.
The residential battery packs are getting a LOT of attention, partly due to the lack of information at the PR event last Thursday in Hawthorne, Calif. For the last couple of months, I’ve been documenting the lack of a residential market for energy storage, think “community energy” and being able group 100 to 200 hundred solar houses and sell it back to the utility.
That residential market example doesn’t exist, yet.
Tesla Powerwall debuts at Tesla PR event in Hawthorne, CA on Aug 30, 2015.
However, utilities are fully engaged in offering commercial demand/response programs throughout the U.S to large companies and, since last Thursday, Tesla has received over 2,500 reservations for its PowerPack, the commercial and building storage solution.
Currently, Amazon is focusing on clean energy to power its data centers and will roll out a pilot program with Tesla Energy for 4.8 megawatts in Northern California. Tesla is also working with Jackson Family Wines and Target on pilot projects.
“As part of Target’s support to our communities, we’re excited to partner with Tesla on a pilot test at select Target stores to incorporate Tesla Energy Storage as part of our energy strategy,” says David Hughes, senior grp. mgr., Energy Management, Target.
So, yes, Tesla Energy has to deliver a real business solution with these pilot projects and, of course, margins need win out. During Tesla’s conference call, Musk said, “Once we get Gigafactory up and running, and high volume and get the economies of scale working, this is just a guess, but maybe it’s somewhere around 20 percent (battery margins). It’s like we just don’t have enough information to say exactly what that would be (at this point).”
Also from the conference call are the similarities between the car packs and Tesla Energy packs and how that could help economies-of-scale.

JB Straubel, CTO at Tesla Energy, says, “Maybe one point on the cost structure. There’s definitely a lot of commonality in the supply chain and even in the manufacturing base on how we do the modules and sales for the Tesla Energy products along with the vehicle products.”
Sounds promising, especially when Tesla is on record saying it should drive down battery costs by 30% when the Gigafactory is fully operational.
So, the company has to deliver but mind share is already there for the Silicon Valley company and its energy storage products. According to Bloomberg, Tesla Energy’s current reservations–no money down is needed–for both the home and commercial products would equate to $800 million if they could deliver immediately.
Ten years from now, who’s going to get credit for leading the clean energy battery storage drive? I doubt Panasonic and Sony and their much pricier battery storage solutions would roll off your tongue.
SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo
SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.
SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.
The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.
The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.

Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.
Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.
The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.
Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990
Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.
However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.
Multi-Row Climate Control
Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility
One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.
Tesla has improved upon this with the Model Y L:
This is a drastic difference. https://t.co/wTdhitD5aA pic.twitter.com/z6hFs0Jkss

PowerShare will be included
Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.
Wireless Charging Pad
There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit
Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.
Thermal Management Improvements
These improvements in the Model Y L were seen with thermal management:
- Up to 15% faster cabin cooling
- +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
- 8x more solar energy reflection off of glass roof
- 30% reduction in solar energy entering the cabin
