With Tesla ramping the production of its residential battery and solar products, Solar Roof installations are bound to become more commonplace. Being a new type of PV system, Tesla’s solar shingles could provide challenges to emergency personnel and first responders who are not trained to handle the glass tiles. The California Department of Forestry and Fire Protection, better known as CAL Fire, recently released a video demonstrating techniques on how to best respond to a home fitted with a Tesla Solar Roof installation.

CAL Fire veteran Brock Archer noted that the construction of the Tesla Solar Roof is actually pretty simple, with the photovoltaic cells being mounted on top of a firestone clad guard, which is a thin moisture barrier. The wiring for the tiles themselves is hidden underneath the shingles. Archer further stated that each Solar Roof tile represents itself as three shingles on the roof. As per Tesla’s design, one to four of these tiles can be wired together to create branches, which are then wired to a diode trunk harness. The diode trunk harness carries the electricity from all the panels through the roof itself.

Archer further noted that while the diode trunk harness operates at a high voltage, testing on the Solar Roof system indicates that there is almost zero risk of shock or electrocution when cutting or crushing the tiles. There is also almost no risk of electric shock when cutting through the diode trunk harness. A rapid shutdown device that’s installed close to the solar arrays, terminates DC power in the roof when AC power is interrupted.

While Tesla’s glass solar roof tiles are designed to be nearly indestructible, conducting emergency extrication maneuvers through the photovoltaic system could prove tricky. Fellow CAL Fire veteran Nick Papa noted that the Solar Roofs are very slippery, and are best treated like metal and slate roofs. Thus, for firefighters and other emergency personnel, using a ladder to gain access to a Solar Roof-equipped house is necessary. The fire veteran also noted that the tools such as fire axes and chainsaws work well with the Solar Roofs, as the shingles could be removed quickly without any problems.

The recently released emergency response training video for Solar Roof installations ultimately showcases the clever design of Tesla’s next-generation PV system. When Elon Musk unveiled the Solar Roof tiles back in 2016, Musk highlighted the shingles’ aesthetics and durability. If this recent video is any indication, it seems like the Solar Roof tiles are also designed with safety in mind.

In a recent statement, Tesla CTO JB Straubel noted that the company is aggressively ramping the production of its residential solar and battery products. Despite increasing competition from other residential solar companies in the United States, Straubel stated that Tesla is in no way stepping back from the residential solar industry. The Tesla CTO also noted that production of Powerwall 2 home batteries is set to ramp later this year. Solar Roof tile production is also expected to hit its full stride in 2019.

Supply Partners Group has secured a distribution agreement for the Tesla Powerwall in Australia, with inventory expected to arrive in late February and official sales beginning in mid-March 2026.

Under the new agreement, Supply Partners will distribute Tesla Powerwall units and related accessories across its national footprint, as noted in an ecogeneration report. The company said the addition strengthens its position as a distributor focused on premium, established brands.

“We are proud to officially welcome Tesla Powerwall into the Supply Partners portfolio,” Lliam Ricketts, Co-Founder and Director of Innovation at Supply Partners Group, stated.

“Tesla sets a high bar, and we’ve worked hard to earn the opportunity to represent a brand that customers actively ask for. This partnership reflects the strength of our logistics, technical services and customer experience, and it’s a win for installers who want premium options they can trust.”

Supply Partners noted that initial Tesla Powerwall stock will be warehoused locally before full commercial rollout in March. The distributor stated that the timing aligns with renewed growth momentum for the Powerwall, supported by competitive installer pricing, consumer rebates, and continued product and software updates.

“Powerwall is already a category-defining product, and what’s ahead makes it even more compelling,” Ricketts stated. “As pricing sharpens and capability expands, we see a clear runway for installers to confidently spec Powerwall for premium residential installs, backed by Supply Partners’ national distribution footprint and service model.”

Supply Partners noted that a joint go-to-market launch is planned, including Tesla-led training for its sales and technical teams to support installers during the home battery system’s domestic rollout.

Tesla’s planned Megapack factory in Brookshire, Texas has taken a significant step forward, as two massive industrial buildings fully leased to the company were sold to an institutional investor.

In a press release, Stream Realty Partners announced the sale of Buildings 9 and 10 at the Empire West industrial park, which total 1,655,523 square feet. The properties are 100% leased to Tesla under a long-term agreement and were acquired by BGO on behalf of an institutional investor.

The two facilities, located at 100 Empire Boulevard in Brookshire, Texas, will serve as Tesla’s new Megafactory dedicated to manufacturing Megapack battery systems.

According to local filings previously reported, Tesla plans to invest nearly $200 million into the site. The investment includes approximately $44 million in facility upgrades such as electrical, utility, and HVAC improvements, along with roughly $150 million in manufacturing equipment.

Building 9, spanning roughly 1 million square feet, will function as the primary manufacturing floor where Megapacks are assembled. Building 10, covering approximately 600,000 square feet, will be dedicated to warehousing and logistics operations, supporting storage and distribution of completed battery systems.

Waller County Commissioners have approved a 10-year tax abatement agreement with Tesla, offering up to a 60% property-tax reduction if the company meets hiring and investment targets. Tesla has committed to employing at least 375 people by the end of 2026, increasing to 1,500 by the end of 2028, as noted in an Austin County News Online report.

The Brookshire Megafactory will complement Tesla’s Lathrop Megafactory in California and expand U.S. production capacity for the utility-scale energy storage unit. Megapacks are designed to support grid stabilization and renewable-energy integration, a segment that has become one of Tesla’s fastest-growing businesses.

Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year. 

The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.

As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.

The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.

Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.

Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.

Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation. 

“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.
