Tesla Top 5 Week in Review: Solar Roof, P100D Race Car Composites, Model 3 sighting, and more
The top articles of the week at Teslarati revolved around some of the Biggest Tesla Stories for 2017, with solar roof production at Gigafactory 2 and a Model 3 prototype sighting taking the news fast lane. But sometimes the small voices are the ones that are heard the loudest, with an upcoming Tesla commercial as the result. Tesla has become the first company to provide large magnitude solar energy for a utility, and a self-described vegan hippie race car chick will unveil an electric GT Tesla P100D race car later this month — and it’s made of biocomposite materials. Here are those stories, and more.
Tesla gears up for Solar Roof production at Gigafactory 2, Panasonic will have major role at plant
Tesla’s factory in Buffalo, dubbed Gigafactory 2, will be a site of solar roof tile manufacturing. Panasonic, Tesla’s strategic partner, will manufacture solar cells there with ancillary help from Silevo, which SolarCity acquired in 2014. Panasonic, which has a $250 million investment in the facility, will also produce full solar panels in Buffalo, and those will be sold to Tesla. Panasonic has agreed to grant adjustable pricing to Tesla for solar products it purchases from the Japanese electronics company over the next 10 years.
Tesla Model 3 spotted testing along Hyperloop track outside of SpaceX
A polished and very complete-looking silver Tesla Model 3 prototype was caught in rare video footage this week doing test runs on a street outside SpaceX and the Hyperloop test track. Unplugged Performance, which produces upgrades for Tesla vehicles, spotted the prototype cruising around the nearby area. The Model 3 is newest vehicle in the Tesla catalog, with a starting price of $35,000 and an expected production date of summer, 2017. The prototype has made guest appearances at a number of events and venues, including an investor event in January.
Tesla launches “Project Loveday” contest for fan-made commercials
This week, Tesla CEO Elon Musk — whose Twitter feed is a much-visited social media site by journalists, Tesla owners, and cleantech aficionados — announced that he would hold a contest for homemade advertisements after receiving a challenge from a fifth grade student. “Thank you for the lovely letter. That sounds like a great idea. We’ll do it!” Musk tweeted to young Bria. The “Project Loveday” contest, which will end on May 8, 2017, will review the best fan-made commercials. According to the blog post on Tesla’s website, entrants can submit a link to a 90 second or less YouTube video along with a brief description.
Tesla locks in 20-year deal to provide solar electricity to Kauai Island Utility
On Kauai, which is described by many as the most picturesque of the Hawai’ian islands, daytime reliance on solar energy and other renewables has traditionally dissipated when the sun sets. Now that’s all changing, as the Kauai Island Utility Cooperative (KIUC) is drawing energy from 272 Tesla power packs to provide electricity after dark. The measure will save KIUC 1.6 million gallons of diesel fuel annually and will cut KIUC costs per kilowatt hour from 15.5 cents down to a fixed price of 13.9 cents for the next 20 years. The agreement shifts the power generation from the utility to Tesla, and Tesla is the first company with which any utility company has contracted for a system of this magnitude.
Leilani Münter will help showcase Tesla race car “biocomposites” made of natural fibers
Electric GT’s Tesla P100D race car will be in Paris on March 15 with Leilani Münter showcasing the car’s high performance composite material made from natural fibers. Swiss firm Bcomp configures natural fibers into ultralight components known as “biocomposites” for the Electric GT race vehicles. These materials are formed by a matrix which mimics the structure of the living materials, maintains strengthening properties, and provides biocompatibility. An environmental activist, Münter believes it is essential for humans to adapt and evolve to a sustainable way that does not destroy the world. The racer is an advocate for renewable energy, solar power, electric cars, and plant-based diets and has been a longtime Tesla protege.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
