Tesla on track to generate $500M from SolarCity merger, Solar Roof launch slated for second half of the year

In November, shareholders approved a deal for Tesla to buy SolarCity Corp. in a transaction worth approximately $2.6 billion. Since that time, investors have pushed Tesla CEO Elon Musk to prove that this acquisition is fiscally responsible, with high expectations for the final quarter of 2016 and a positive outlook for 2017.
In the Tesla Q4 and full year 2016 financial results and Q&A webcast on Wednesday, SolarCity was well-celebrated as an essential element of “the world’s only integrated sustainable energy company, from generation to storage to transportation.”
Discussions around the Tesla Q4 financial statement included the results of SolarCity’s operations from the close of the acquisition on November 21 to December 31, 2016. Increases totaling Q4 GAAP operating expenses supported the growing Tesla business spectrum alongside $85 million of solar-related operating expenses since the acquisition of SolarCity. Moreover, Tesla also received $214 million in cash from the acquisition of SolarCity, which helped sweeten the Q4 report.
Tesla reports that it is “on track to generate $500M in cash” in the next two years. As Musk quipped at the beginning of the webcast, “I admire long term planning.” A significant component of that advanced fiscal forecast is the “achieve the cost synergies” that Tesla committed to upon acquiring SolarCity. Tesla outlined three ways that they intend to build the SolarCity.
- Cutting advertising spending: Ad Age commented in the past that “Tesla Motors has no advertising, no ad agency, no CMO, no dealer network. And that’s no problem.” As with today’s investor’s letter and webcast, the company receives positive coverage for posting its quarterly profits and announcing expansion of its product line and service networks. Musk, like many celebrity business people and politicians these days, uses Twitter to introduce company concepts and to generate buzz about everything Tesla— and that will extend more and more to SolarCity in the second half of 2017.
- Selling solar products in Tesla stores: The move to reinvent its retail sales strategy comes as part of Tesla’s long term business plan to promote a 360° sustainable energy lifestyle — complete with electric cars, solar power, and home battery storage. Selling a lifestyle and a way of thinking, Tesla retail store reconfiguration has deepened its already formidable brand, which offers a premium lifestyle experience that complements a high-tech image. SolarCity products, as part of this melange, will become an essential element of the Tesla product catalog at retail locations, with emphasis on markets with the most demand for solar energy products.
- Shifting away from leasing solar systems: At the end of 2016, SolarCity CEO Lyndon Rive had announced that the company expected to reduce the number of leases while loans and cash purchases increase. Now the market is expected to trend steadily toward direct ownership as loan designs become more appealing, system costs continue to fall, and more people see the benefit in a purchase.
Tesla is well-positioned in the alternative energy sector with SolarCity, as solar power installations doubled in 2016 over 2015 as more and more areas of the U.S. began pulling their power from the sun. Indeed, for the first time, solar power installations formed the largest group of electricity generating capacity of any energy source. Nearly 40 percent of new power generation projects added last year were solar, in terms of electrical production capacity. A record 22 states each added more than 100 megawatts.
The trend should continue in the next two years, consistent with the Tesla SolarCity viability plan, according to a report by GTM Research. They say that the community solar segment is on verge of becoming a mainstream driver of U.S. solar market growth. Starting in 2017, community solar is expected to consistently drive 20% – 25% of the annual non-residential PV market and become a half-gigawatt annual market by 2019.

Tesla recalls Powerwall 2 units in Australia

Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.
Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.
Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.
The issue is related to the cells, which Tesla sources from a third-party company.
Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.

Tesla’s new Megablock system can power 400,000 homes in under a month
Tesla also unveiled the Megapack 3, the latest iteration of its flagship utility scale battery.

Tesla has unveiled the Megablock and Megapack 3, the latest additions to its industrial-scale battery storage solution lineup.
The products highlight Tesla Energy’s growing role in the company, as well as the division’s growing efforts to provide sustainable energy solutions for industrial-scale applications.
Megablock targets speed and scale
During the “Las Megas” event in Las Vegas, Tesla launched Megablock, a pre-engineered medium-voltage block designed to integrate Megapack 3 units in a plug-and-play system. Capable of 20 MWh AC with a 25-year life cycle and more than 10,000 cycles, the Megablock could achieve 91% round-trip efficiency at medium voltage, inclusive of auxiliary loads.
Tesla emphasized that Megablock can be installed 23% faster with up to 40% lower construction costs. The platform eliminates above-ground cabling through a new flexible busbar assembly and delivers site-level density of 248 MWh per acre. With Megablock, Tesla is also aiming to commission 1 GWh in just 20 business days, or enough to power 400,000 homes in less than a month.
“With Megablock, we are targeting to commission 1 GWh in 20 business days, which is the equivalent of bringing power to 400,000 homes in less than a month. It’s crazy. How are we planning to do that? Like most things at Tesla, we are ruthlessly attacking every opportunity to save our customers time, simplify the process, remove steps, (and) automate as much as we can,” the company said.
Megapack 3 is all about simplicity
The Megapack 3 is Tesla’s next-generation utility battery, designed with a simplified architecture that cuts 78% of connections compared to the previous version. Its thermal bay is drastically simplified, and it uses a Model Y heat pump on steroids. The battery weighs about 86,000 pounds and holds 5 MWh of usable AC energy. Tesla engineers incorporated a larger battery module and a new 2.8-liter LFP cell co-developed with the company’s cell team.
The Megapack 3 is designed for serviceability, and it features easier front access and no roof penetrations. About 75% of Megapack 3’s total mass is battery cells, with individual modules weighing as much as a Cybertruck. It’s also tough, with an ambient operating temperature range from -40C to 60C. This should allow the Megapack 3 to operate optimally from the coldest to the hottest regions on the planet.
Production is set to begin at Tesla’s Houston Megafactory in late 2026, with planned capacity of 50 GWh per year. Additional supply will come from Tesla’s 7 GWh LFP facility in Nevada, which is expected to open in 2025, as well as with third-party partners.

Tesla Energy is the world’s top global battery storage system provider again
Tesla Energy captured 15% of the battery storage segment’s global market share in 2024.

Tesla Energy held its top position in the global battery energy storage system (BESS) integrator market for the second consecutive year, capturing 15% of global market share in 2024, as per Wood Mackenzie’s latest rankings.
Tesla Energy’s lead, however, is shrinking, as Chinese competitors like Sungrow are steadily increasing their global footprint, particularly in European markets.
Tesla Energy dominates in North America, but its lead is narrowing globally
Tesla Energy retained its leadership in the North American market with a commanding 39% share in 2024. Sungrow, though still ranked second in the region, saw its share drop from 17% to 10%. Powin took third place, even if the company itself filed for bankruptcy earlier this year, as noted in a Solar Power World report.
On the global stage, Tesla Energy’s lead over Sungrow shrank from four points in 2023 to just one in 2024, indicating intensifying competition. Chinese firm CRRC came in third worldwide with an 8% share.
Wood Mackenzie ranked vendors based on MWh shipments with recognized revenue in 2024. According to analyst Kevin Shang, “Competition among established BESS integrators remains incredibly intense. Seven of the top 10 vendors last year struggled to expand their market share, remaining either unchanged or declining.”

Chinese integrators surge in Europe, falter in U.S.
China’s influence on the BESS market continues to grow, with seven of the global top 10 BESS integrators now headquartered in the country. Chinese companies saw a 67% year-over-year increase in European market share, and four of the top 10 BESS vendors in Europe are now based in China. In contrast, Chinese companies’ market share in North America dropped more than 30%, from 23% to 16% amid Tesla Energy’s momentum and the Trump administration’s policies.
Wood Mackenzie noted that success in the global BESS space will hinge on companies’ ability to adapt to divergent regulations and geopolitical headwinds. “The global BESS integrator landscape is becoming increasingly complex, with regional trade policies and geopolitical tensions reshaping competitive dynamics,” Shang noted, pointing to Tesla’s maintained lead and the rapid ascent of Chinese rivals as signs of a shifting industry balance.
“While Tesla maintains its global leadership, the rapid rise of Chinese integrators in Europe and their dominance in emerging markets like the Middle East signals a fundamental shift in the industry. Success will increasingly depend on companies’ ability to navigate diverse regulatory environments, adapt to local market requirements, and maintain competitive cost structures across multiple regions,” the analyst added.
