Tesla Solar Roof 15kW installation completed in 4 days: Time-lapse video
A recent video posted by Weddle and Sons Roofing has revealed how fast a 4,000 sq.ft. (about 372 sq.m) roof could be replaced with Tesla Energy’s Solar Roof tiles. The roofing company installed a sizeable 15kW Tesla Solar Roof system on a Topeka, Kansas house. The entire installation, including PV tiles, glass tiles, and flashings, took a total of four days to complete.
The Friday before Weddle and Sons Roofings installed Tesla Solar Roof, the existing roof and dry-in with double-layer Firestone underlayment was torn off the house. Based on the roofing company’s description, tearing off the existing roof seemed to take only one day.
In total, the 15kW Tesla Solar Roof installation, covering 4,000 sq.ft. (about 372 sq.m) seemed to take only five days, including the tear-down of the old roof. For comparison, it usually takes several days to install a new roof, depending on the material used.
According to amconstruct.com, the estimated time for roof installations are as follows:
- Wooden Shingles – 3 – 4 days
- Slate Tiles and Shingles – 6 – 7 days
- Asphalt Shingles – 1 – 2 days
- Concrete Tiles and Shingles – 8 – 9 days

Elon Musk announced the release of Tesla Solar Roof Version 3 during the EV automaker’s Q3 earnings call in 2019. Tesla scaled-up production of its Solar Roof at Gigafactory New York once Version 3 was ready.
Installation for the latest iteration of Solar Roof steadily picked up at the beginning of this year, before COVID broke out. In February, Tesla CEO Elon Musk tweeted that the company was planning to ramp Solar Roof installation across the United States.
Along with the announcement, Musk included a link to Tesla’s Solar Roof Team page, subtly inviting people to apply for the company’s open positions for roofers, installers, and electricians. Musk has stated in the past that Tesla will need more manpower (i.e. roofers, installers, and electricians) to ramp Solar Roof installation.
COVID ultimately stalled some of Tesla Energy’s progress with production and installation of Solar Roof V3. However, Elon Musk and the rest of the Tesla team remained positive that Solar Roof installation could get back up and running despite the pandemic.
“And internally, we want to have at least 1,000 Solar Roof install teams with — and taking a week or perhaps a little less than a week to do an install, which gets you 1,000 a week roof installations. We see demand is good. Production is good. So it’s really all about the install,” said Elon Musk during the Q1 2020 earnings call.
The CEO also talked about Solar Roof’s rising demand globally. He alluded to expanding Tesla Solar Roof installations internationally by the end of the year back in February 2020 before the pandemic hit.
“And then like I said, also build out the training, the very diverse group of companies in the roofing industry to also install Solar Roof that, I think will scale — allow us to scale far beyond 1,000 a week. We’re also seeing a lot of interest outside of North America. So we do expect this to be a product that is international and actually seeing a tremendous amount of interest from China on the Solar Roof. So we’re confident, this will be a very significant product for the Company over time,” Musk said.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance
Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.
Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.
Tesla Full Self-Driving v14.3.5 Performance
The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.
Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.
We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.
FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:
“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.
Terrible Parking
Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:
Yeah it seems like FSD v14.3.5 is having some issues with parking early on https://t.co/Bw5ULfVmDq pic.twitter.com/RHdpjOEpIo

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features
Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:

Tesla makes the cut on California’s newest EV Rebate program
California just signed a $270 million EV rebate into law and it starts this summer.
California Governor Gavin Newsom signed SB 168 into law on Monday, July 13, 2026, creating a $270 million EV rebate program that delivers money directly at the dealership rather than as a tax credit applied months later. The program, called MyFirstEV, is funded equally by California’s state budget and participating automakers, with each contributing $135.5 million to make the math work.
The timing is directly tied to the loss of federal support when the $7,500 federal EV tax credit ended, removing the most significant consumer incentive that had driven EV adoption in the U.S. California, which accounts for roughly one-third of all EVs sold nationally, moved to fill that gap with a state-level replacement.
The rebate structure is straightforward. First-time EV buyers can receive $3,500 off any new battery-electric vehicle with an MSRP up to $50,000. Used EVs priced at $25,000 or below qualify for a $1,750 rebate. The credit is applied at the point of sale, which removes the friction of the old federal system where buyers had to wait for tax season to see the benefit. The program goes live later this summer, with the California Air Resources Board expected to release full participation details next month.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
For Tesla buyers, the implications are mixed. The Tesla Model 3 RWD at $42,490 and the Model 3 Long Range at $47,490 both fall under the $50,000 cap and would qualify for the full $3,500 rebate for first-time buyers. The Model Y, which starts at $44,990 after Tesla’s recent price adjustment, also qualifies. The Model X, Model S, and Cybertruck all exceed the cap and receive no benefit. As Teslarati has reported, the program also includes a carve-out exempting California-based automakers like Rivian and Lucid from the price cap entirely, a provision that puts Tesla at a disadvantage since it relocated its headquarters to Texas in 2021.
Other qualifying vehicles include the Chevrolet Equinox EV, Ford Mustang Mach-E, Hyundai Ioniq 5, Kia EV6, and Volkswagen ID.4.

Tesla Semi enters new Pilot Program with interesting challenge
The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”
Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.
Tesla Semi spotted on journey home after winter performance testing
PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.
CEO of PTI Tyler Ellison said:
“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”
PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.
Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.
PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:
“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”
PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.
