Tesla Solar Roof and Solar Panels to be sold exclusively integrated system with Powerwall batteries

Published

on

In recent comments on Twitter, Elon Musk announced that Tesla’s Solar Roof and traditional solar panels would now be sold only as an integrated product with the Powerwall, the company’s popular residential battery system. Tesla would start selling the bundled residential energy products beginning next week. 

In a later tweet, Musk mentioned that having an integrated solar and battery system should present some advantages, such as a more seamless installation process. The Powerwall battery would also just interface between the utility meter and the home’s main breaker panels, providing customers with backup energy just in case a power outage ensues. 

“Solar power will feed exclusively to Powerwall. Powerwall will interface only between utility meter & house main breaker panel, enabling super simple install & seamless whole house backup during utility dropouts,” Musk wrote. 

The Tesla Powerwall stands as one of the most popular residential battery systems in the market, partly due to the fact that it offers the least expensive storage option on a per-kWh stored basis, as per data from EnergySage in its eleventh semiannual Solar Marketplace Intel Report. Considering that the demand for the battery has resulted in long wait times for Powerwall customers, Tesla’s decision to sell the energy storage system with solar products makes sense.

Musk’s recent updates came not long after a Twitter interaction with ARK Invest Director of Research Brett Winton, who described the current situation with his Tesla solar system. According to the analyst, his solar + Powerwall setup has not generated a single watt-hour since its installation back in January, simply because the utility has not approved the connection. In his response, Musk noted that utility permission is typically needed when the Powerwall is full and capable of stabilizing the grid

Tesla’s Solar Roof tiles have been the topic of several news articles as of late, partly due to reports from customers who noted that their system’s estimates have seen a notable price increase. The price increases are significant, with one customer telling Ars Technica that their Solar Roof quote had been updated from its initial estimate of $66,000 to a far more expensive $87,000. “Tesla has reneged on its solar roof contracts and has raised the prices for people (like me) who have already signed a contract with them,” the Solar Roof customer noted. 

Tesla has not provided details about these reported price increases, though the company’s online cost estimator for the Solar Roof now asks potential customers about their roof’s “complexity,” which considers factors like pitch, number of joints, chimneys, and other features. Tesla also highlighted in its online cost estimator that “complex roofs take more time and material to install than simple roofs.”

The Tesla Model 3 recently captured the title of “most economical electric vehicle to own” in a new study performed by research firm Zutobi.

Perhaps one of the biggest and most popular reasons people are switching to EVs is the cost savings. Combining home charging, lower maintenance costs, and tax credits has all enabled consumers to consider EVs as a way to save money on their daily drivers. However, there are some EVs that are more efficient and cost-effective than others.

Tesla police fleet saves nearly half a million in upkeep and repair costs

Zutobi‘s new study shows that EV cost-effectiveness comes at different levels. For example, some cars are simply better than others on a cost-per-mile basis. The study used a simple process to determine which EVs are more cost-effective than others by showing how much it would cost to drive 100 miles.

National averages for energy rates have been used to calculate the cost as they widely vary from state to state.

The Rear-Wheel Drive Tesla Model 3 was listed as the most economical vehicle in the study:

“The standard Tesla Model 3 is the most economical electric vehicle to drive in 2025. With a usable battery capacity of 57.5 kWh and a real-world range of 260 miles, it costs just $3.60 to drive 100 miles. That translates to an impressive 2,781 miles per $100 of electricity—making it the most efficient choice for EV owners nationwide.”

It had an estimated cost of just $3.60 to drive 100 miles.

The Tesla Model 3 Long Range All-Wheel Drive was second, the study showed:

“Next is the Long Range version of the Model 3, which offers extended range and dual-motor all-wheel drive. With a larger 75 kWh battery and 325 miles of range, the cost to drive 100 miles is slightly higher at $3.75, still equating to a strong 2,665 miles per $100.”

This version of the Model 3 had a price of just $3.75 to drive 100 miles.

In third, the BMW i4 eDrive35 surprised us with a cost of just $4.12 to drive 100 miles:

“Rounding out the top three is the BMW i4 eDrive35, with a 67.1 kWh battery and a real-world range of 265 miles. Drivers can expect to pay $4.12 per 100 miles, which still allows for 2,429 miles per $100—a solid choice for those seeking luxury and efficiency.”

Several other Teslas made the list as well. The Model 3 Performance ($4.34 per 100 miles) was sixth and tied with the Volkswagen ID.3 Pure, the Tesla Model S Long Range ($4.35 per 100 miles) was 8th, and the Tesla Model Y Long Range was ninth ($4.36 per 100 miles).

Tesla offers new discounts on Cybertruck inventory

Tesla is knocking up to $10,550 off of Cybertruck units in inventory

Tesla is offering new discounts on Cybertruck units in inventory, giving customers a chance to snag a unit of the all-electric pickup for a slight reduction in price. Some are even coming with additional perks to make the offer even sweeter.

Tesla is now offering up to $10,550 off of Cybertruck inventory units across the United States. This is up from previous discounts of $6,000 on inventory Cybertrucks, and it will apply to 2024 model year vehicles.

Non-Foundation Series Cybertrucks are getting up to $10,550 off of their original prices, while Foundation Series pickups are getting up to $10,000 off. These are great deals and should help clear out some inventory from last year’s models.

Additionally, Foundation Series Cybertrucks purchased will receive free lifetime Supercharging, another great addition to make the deal even better than the $10,000 off.

The move comes as Tesla is still ramping Cybertruck production and is hoping to stimulate some additional demand for the vehicle, as it is holding on to these units. These are not Demo Drive units that have been driven by any number of people who were looking for a quick test drive.

Tesla launched a new configuration of the Cybertruck just last week with the Long Range Rear-Wheel-Drive, which undercuts the All-Wheel-Drive option by roughly $10,000.

Tesla released the Cybertruck RWD to make the AWD look like a deal

However, Tesla stripped the vehicle of several features, including Air Suspension, a tonneau cover, and interior features. For example, the Rear-Wheel-Drive trim of the Cybertruck has textile seats and no rear touchscreen, two things that come standard in the other trim levels.

The Cybertruck is the best-selling electric pickup in the United States, outperforming formidable competitors like the Ford F-150 Lightning and Chevrolet Silverado EV. However, Tesla is still working to get the vehicle to a lower price point that makes it more accessible to consumers, as its current pricing is a far cry from what was intended.

Rivian grapples with challenges from Trump’s auto tariffs

Rivian CEO warns Trump’s auto tariffs will squeeze the EV industry. Scaringe says auto tariffs threaten rising costs & slower production.

Rivian is grappling with challenges arising from President Trump’s auto tariff. Rivian CEO RJ Scaringe recently enumerated the difficulties automakers face and elaborated on the impact of Trump’s auto tariffs on the electric vehicle (EV) industry.  

President Trump’s auto tariffs were announced last month, imposing 25% tariffs on imported vehicles effective April 3, 2025, and levies on auto parts starting in May.

Scaringe talked a bit about the complexity of the automotive supply chain with Fox Business. Rivian’s R1T pickup, R1S SUV, and commercial electric van are manufactured at its Normal, Illinois plant. Scaringe boasted that Rivian has a “very U.S.-centric supply chain.

Yet, the complex global supply chain poses hurdles for U.S. automakers who want to comply with Trump’s auto tariffs.

“One of the things with automotive is the supply chain is so complex, where we have hundreds of suppliers providing parts from, say, a headlight or a tow hook or tires or the structure under the skin here that are coming from not only a set of suppliers that supply to us, but those suppliers have suppliers, and then in turn, those suppliers have suppliers, so there’s tier two, tier three,” Scaringe explained.

China’s restrictions on rare-earth material exports–in response to Trump’s 145% tariff on Chinese imports–further complicate matters. Rare-earth materials are critical for EV motor magnets and batteries. Nearly all rare-earth materials are processed exclusively in China.

“The trade restrictions and what we’re seeing in terms of rare earth metals out of China, that’s a real challenge for electric vehicles,” Scaringe noted.

Batteries comprise up to 40% of an EV’s cost. Goldman Sachs noted that battery costs have been falling in recent years. The investment bank estimated EV battery costs would drop by 50% between 2023 and 2026. However, China’s decision to restrict rare-earth materials may increase battery costs.

Wedbush analyst Dan Ives called the tariffs a source of “pure chaos” for the auto industry, stating, “A U.S. car made entirely with U.S. parts is a fictional tale.”

Ives warned automakers could increase car prices between $5,000 to $10,000. Wedbush predicts a potential change in Trump’s auto parts tariffs could ease disruptions.

For Rivian, starting prices near $70,000 limit room for cost increases without impacting sales. As trade tensions escalate, Rivian faces rising costs and potential production slowdowns, threatening its growth in a shifting EV landscape.
