Tesla will incorporate Panasonic cells into glass solar roof tiles when production begins in summer 2017

Tesla announced today that it has finalized an agreement with Panasonic that would allow both companies to begin manufacturing high-efficiency photovoltaic (PV) cells and modules from its Buffalo, NY factory. The update comes months after Tesla first announced that it had entered into a non-binding letter of intent with Panasonic under which the two companies would collaborate on the manufacturing and production of PV cells and modules. However, the agreement was only valid upon shareholders’ approval of Tesla’s acquisition of SolarCity – a deal that saw an overwhelming majority of voters approving the merger.

Tesla and Panasonic will initially build PV cells and modules for use in traditional solar panels, but will eventually incorporate Panasonic cells into Tesla’s Solar Roof product when production begins mid-2017. The PV cells will be integrated directly into the glass solar roof tiles which Tesla is offering in a variety of designs.

As part of Tesla CEO Elon Musk’s vision of the future, largely comprised of sustainable transportation and storage systems for renewable energy, Tesla’s solar products will be integrated with Panasonic cells and operate seamlessly with the company’s home and commercial energy storage products, Powerwall and Powerpack. Tesla indicates that it has plans to ramp up to 1 Gigawatt of PV module production by 2019.

Today’s announcement also reaffirms Tesla’s commitment to creating American-based jobs at Buffalo, NY, home to SolarCity’s solar factory. We had previously reported that SolarCity has begun holding workforce information sessions as the company prepares to hire nearly 1,400 workers for its $900 million solar factory located at Riverbend.

Expect to see more announcements from Tesla as it continues to fortify its long-standing partnership with Panasonic. Panasonic is an investor and strategic partner at the Gigafactory in Sparks, Nevada where it manufactures cylindrical 18650 and 2170 lithium-ion cells used in Tesla’s fleet of vehicles and grid storage products.

Panasonic has agreed to cover capital costs required at the Buffalo, NY solar factory. In exchange, Tesla will continue on its long-term purchase commitment from Panasonic, namely, an extension into the purchase of Panasonic PV cells.

Read Tesla’s full announcement below:

Tesla and Panasonic have finalized an agreement this week to begin the manufacturing of photovoltaic (PV) cells and modules at the Buffalo, NY factory. These high-efficiency PV cells and modules will be used to produce solar panels in the non-solar roof products. When production of the solar roof begins, Tesla will also incorporate Panasonic’s cells into the many kinds of solar glass tile roofs that Tesla will be manufacturing. All of these solar products will work seamlessly with Tesla’s energy storage products, Powerwall and Powerpack. Production of the first PV modules will begin in summer 2017, and will ramp to 1 Gigawatt of module production by 2019.

As Tesla and Panasonic begin production, Buffalo will continue to expand Tesla’s American manufacturing base and create thousands of new jobs in the coming years. Tesla reaffirms SolarCity’s commitment to create over 1,400 jobs in Buffalo—including more than 500 manufacturing jobs. Panasonic, with its technological and manufacturing expertise in PV production, will also work with Tesla on developing PV next generation technology at SolarCity’s facility in Fremont, CA.

Elon Musk says this essential Tesla Robotaxi feature will be here soon

Tesla will work to solve automatic parking at available Supercharger stalls with future updates.

Elon Musk reiterated that one feature, which is ultimately an essential part of the operation of the Tesla Robotaxi platform, will be here soon.

Tesla released a new video of its longest Full Self-Driving demo yesterday, showing off a zero-intervention drive from San Francisco to Los Angeles. The drive is roughly seven hours and 360 miles long, and not a single need for the driver to touch the wheel was recorded.

Tesla flexes its most impressive and longest Full Self-Driving demo yet

There was one question that was brought up by an owner that brings up an interesting point. Tesla still needs to solve the vehicle’s ability to pull into Superchargers automatically, something that does not currently have a high success rate, at least for the owner who got a response from CEO Elon Musk.

Musk assured him that a Tesla’s ability to pull into open parking spaces at Superchargers would be more reliable with future software updates. Owners can see how many and which exact stalls are available before traveling to a Supercharger, so Teslas should be able to identify these stalls and pull in automatically:

This is a small part of what will be imperative for the charging experience when Robotaxi launches in the coming years. Tesla plans to enable customer-owned cars to potentially enter the Robotaxi fleet and become an autonomous ride-sharing vehicle by next year.

However, it still needs to figure out autonomous charging. There are two parts to that process: pulling into the spot and charging without human need to connect the Supercharger to the vehicle.

Tesla used to consider a robotic snake-arm charger for this, but it has talked about induction charging more recently. Wireless charging seems to be the route that Tesla plans to go, but it might take some time to resolve the energy loss issue and make it an efficient charging method.

Tesla flexes Robotaxi wireless charging — autonomy from top to bottom

Tesla has said its wireless charging efficiency is “well above 90 percent.”

Nevertheless, Tesla is still working toward figuring out all of the edge cases of Robotaxi operation. Figuring out charging without the need of a human is just one part of the puzzle it still has yet to solve, but with its improvements over the past few years, there’s no doubt Tesla will find the missing piece.

Tesla Superchargers get massive nod in new study showing reliability

It showed Tesla Superchargers had the highest score on the 1,000-point scale with 709. They also had the highest reliability, as respondents reported they only had failed charging visits at Tesla Superchargers four percent of the time.

Tesla Superchargers got a massive nod in a new study that showed reliability across EV charging suppliers as electric car ownership in the United States continues to grow.

J.D. Power’s 2025 U.S. Electric Vehicle Experience Public Charging Study aims to find the most (and least) reliable charging suppliers for EV owners.

While charging has become much more popular over the past few years, thanks to the increase in sales of electric vehicles, they are still not quite as plentiful as gas pumps for combustion engine cars.

Tesla is rolling out a new ‘Supercharger queue’ in an effort to end one issue

For this fact alone, it is imperative that EV charging companies offer a fast and reliable product that will enable confidence and peace of mind for car owners. There are quite a few companies out there, but Tesla has the most expansive charging network, not only in the U.S., but globally.

It also has the most reliable chargers, a fact that was reiterated in this year’s J.D. Power study, which was released today.

It showed Tesla Superchargers had the highest score on the 1,000-point scale with 709. They also had the highest reliability, as respondents reported they only had failed charging visits at Tesla Superchargers four percent of the time. This beat out Electrify America at six percent, Red E at 10 percent, and EVgo and 12 percent.

These companies were the only ones to report failed charging visits below the average.

Tesla’s 709 score on the 1,000-point scale was a 22-point drop from last year, but the study said that most of the complaints came from non-Tesla owners.

Many non-Tesla EVs now have access to the company’s Supercharging Network, and the complaints came from those drivers as they stated the process and payment were not as streamlined for them.

Brent Gruber, Executive Director of the EV practice at J.D. Power, said:

“Tesla has facilitated an experience for its owners by creating an optimal technical environment that makes the charging process very easy to use and complete payments. That process isn’t quite as streamlined for non-Tesla owners.”

This likely came from the increased per-kilowatt-hour rate that non-Tesla owners are required to pay for having access to the company’s massive charging network.

For Tesla owners, reliability is not much of a concern. Apart from vandalism, it is pretty rare that a Supercharger stall is out of service, but, of course, it happens.

The important thing to note is that this study continues to show Tesla’s focus on keeping its charging network up and running, especially now that non-Tesla owners are able to utilize them.
