It has been a big few weeks for smart electrical panel-maker Span. The company announced major deals with Pulte Homes and utilities with Landis + Gyr. The startup also expanded its lineup to include small home and apartment-sized panels and even subpanels
But firstly, why do we even need $3500 smart electric panels?
Founded by the former head of Powerwall development and Tesla Energy Arch Rao, Span has been creating smart circuit breaker boxes for homes for a few years.
Span smart circuit boxes were launched in 2020 at a price of $7000 and require specialized electrician installations in low numbers.
Since then, the price has halved to $3500 (or $2900 after the IRA tax credit), and the number of Span installers has expanded, leading to much lower costs and, with this week’s announcements, much-expanded capabilities.
Why Span smart circuit breaker boxes?
As people dump petroleum-based vehicles and home heating and move to EVs and heat pumps, the electrical service lines that homes use are getting taxed. Even 240V/200A service, which a few years ago was very high end, can almost entirely be used up by a few EVs and a whole-house heat pump system. An 80A EV charger will take close to half of 200A service.
With dumb panels, electricians are limited to those 200A, or they’re forced to bring in more power from the street, which can cost thousands or even tens of thousands of dollars along with a lot of time and effort.
Enter the smart panel. Span panels can monitor home power usage and turn off high-power-use items like car chargers, pool pumps, and water heaters when the capacity starts to fill up. Users can set priorities, and there are 32 different smart breakers to wire up many household items.
Solar and Batteries
It isn’t just EVs and heat pumps that are going into new homes. More and more people are looking to solar and battery storage to help mitigate energy costs and outages. These each require a huge breaker and, on dumb panels, eat into those allotted 200A.
Span helps manage these pieces of technology as well. Span can set the home to be run off solar and save energy-intensive operations like charging EVs and Powerwalls for low-energy-cost timeframes.
Obviously, with Rao’s history with Tesla, Powerwalls, Tesla inverters, solar panels, and gateways are fully supported. But other major batteries, such as Franklin WH, Enphase IQ Battery, and LG Chem RESU2 SolarEdge Energy Bank, are also supported.
Span Announcements
Span announced this week that smaller 24-circuit and 16-circuit model boxes are available for smaller homes, apartments, and commercial usage. These can also be utilized as smart subpanels, and there’s even a panel with a built-in meter that is being tested and readied by utilities (details forthcoming).
There’s also a bigger 48-breaker panel coming for new homes. Prices aren’t set yet, and obviously, installers will get discounted prices in bulk.
More announcements are expected in the next few months, which should be exciting for Span.
Electrek’s take:
As I’ve added solar, batteries, EVs, and heat pumps, not just for HVAC but also for water heating and clothes washing, I’m feeling the strain on my 200A service. Our electrician initially recommended running another 200A line that would cost over $10,000. Another option was only having 1 EV charger (which we split with a Neocharge)
Installing a Span will run a fraction of the cost, allow us to add EV chargers and, as a bonus, will allow me to better monitor and control the loads going into and out of my home. That will also save money in the short term and we’ll likely be able to move to better rate plans in the longer term.
I’m fairly confident that I won’t need to do much in the way of mitigation because our house, when not heating and car charging, uses less than 2kW of electricity out of the 50kW coming in. We’ve also removed 240V dryers and replaced them with 120V heat pump modelss and are moving from a 240V water heater to a 120V heat pump water heater.
I’ll have a review of the Span after my upgrade is done in a few months.

Elon Musk said today that Tesla will double its electric vehicle production in the US in the next two years.
What would that look like? Let’s do the math.
Today, during a press conference to promote Tesla at the White House, Tesla CEO Elon Musk said the following:
“As a function of the great policies of President Trump and his administration, and as an act of faith in America, Tesla is going to double vehicle output in the United States within the next two years.”
This raises many questions, as Musk’s phrasing of the statement suggests that Tesla is planning to add previously unannounced production capacity in response to Trump’s policies.

However, the reality could be different.
What is Tesla’s current production capacity in the US?
We only know Tesla’s installed capacity, which is much different than its actual production rate.
This is Tesla’s latest disclosed global production capacity at the end of 2024:

In development
In the US, it adds up to 1,025,000 vehicles per year.
In reality, Tesla’s factories are operating at a much lower capacity.
Based on sales and inventory from 2024, Tesla is currently building fewer than 50,000 Model S/X vehicles per year compared to an installed capacity of 100,000 units.
As for Model 3 and Model Y, Tesla is currently building them in the US at a rate of about 600,000 units per year compared to claimed installed capacity of over 800,000 units.
Finally, the Cybertruck is being produced at a rate of less than 50,000 units per year compared to an installed capacity of over 125,000 units.
This adds up to Tesla producing 700,000 units per year in the US in 2024.
What will be Tesla’s new capacity?
Considering Musk mentioned that it will happen “within the next two years”, it is unlikely that he is referring to installed capacity.
The CEO is most likely talking about Tesla’s actual production, which would also make sense, especially considering he mentioned “output.”
Tesla currently outputs roughly 700,000 vehicles per year in the US.
Doubling that would mean bringing the total to 1.4 million units per year, which would be an incredible feat, but it’s not entirely a new plan for Tesla.
First off, Tesla has already announced plans to unveil two new, more affordable models this year. These models are going to be built on the same production lines as Model 3/Y, which would potentially enable Tesla to fully utilize its installed capacity for those vehicles.
That’s another 200,000 units already.
As already mentioned in Tesla’s installed capacity table, the company is currently developing its production facility for the Tesla Semi electric truck in Nevada.
Production is expected to start later this year and ramp up next year. Tesla has previously mentioned a goal of 50,000 units per year. It would leave Tesla roughly a year and half to ramp up to this capacity, which is ambitious, but not impossible.
Then there’s the “Cybercab”, which was unveiled last year.
The Cybercab is going to use Tesla’s next-gen vehicle platform and new manufacturing system, which is already being deployed at Gigafactory Texas.
Production is expected to start in 2026, and Musk has mentioned a production capacity of “at least 2 million units per year”. However, he said that this would likely come from more than one factory and it’s unclear if the other factory would be in the US.
Either way, Tesla would need to ramp up Cybercab production in the US to 450,000 units to make Musk’s announcement correct.
It’s fair to note that all of this was part of Tesla’s plans before the US elections, Trump’s coming into power, or the implementation of any policies whatsoever.
Electrek’s Take
Based on my analysis, this announcement is nothing new. It’s just a reiteration of Elon’s plans for Tesla in the US, which were established long before Trump came to power or even before Elon officially backed Trump.
It’s just more “corporate puffery” as Elon’s lawyers would say.
Also, if I wasn’t clear, we are only talking about production here. I doubt Tesla will have the demand for that, especially if Elon remains involved with the company.
The Cybercab doesn’t even have a steering wheel, and if Tesla doesn’t solve self-driving, it will be hard to justify producing 450,000 units per year.

The average incentive package for a new EV was 14.8% of the average transaction price (ATP), or approximately $8,162, the highest level in more than five years, according to the latest monthly new-vehicle ATP report from Cox Automotive’s Kelley Blue Book.
Incentives for EVs are more than twice the overall market. A year ago, EV incentives were 10.2%. EV incentives, as a percentage of ATP, have increased by 44% in the past year.
In February, at $55,273, new EV prices were lower by 1.2% from January – generally aligned with the industry – and higher by 3.7% year-over-year. The January EV ATP was revised higher by 0.06% to $55,929.
Compared to the overall industry ATP of $48,039, EV ATPs in February were higher by 15.1%, an increase from the 14.9% gap recorded in January.

Donald Trump, the President of the United States, performed what basically amounts to an infomercial at the White House for Tesla, a company controlled by his biggest political donor, a day after its stock crashed.
Yesterday, Tesla’s stock crashed 15% – resulting in a 50% drop from its peak in December.
He has apparently followed through today, but he went a quite a bit further as he held a press conference in front of Tesla vehicles at the White House:

The President, who has previously shared misinformation about electric vehicles being “unusable,” praised Tesla’s vehicles and said that he would be buying a Model S Plaid.
He is not allowed to drive, so he said that he would let White House staff use the vehicle instead.
Tesla’s stock (TSLA) rose up 5% on the publicity stunt today, but it closed up 3.8% compared to being down 15% yesterday.
Electrek’s Take
When I write those headlines, I feel like I’m running The Onion in an alternative universe where satire is the reality.
But you can’t accuse me of “clickbaiting” because this headline is actually accurate.
For years, Trump has been one of the biggest promoters of misinformation about electric vehicles in the US. We have often reported on the ridiculous things he has said about them.
That hasn’t changed. In fact, Trump is still pushing hard against electric vehicles. We recently reported on Trump shutting down 8,000 EV chargers at federal buildings and he is pushing to remove the tax credit on electric vehicles.
This is purely transactional. Elon gave him $250 million, so now that Tesla’s stock is in free fall, he gives him a boost.
Like his Bitcoin pump, it isn’t likely to work. My hope is that it will at least help open the minds of some of his fans to electric vehicles, but I have doubts.
