New information means that the Tesla Powerwall 3 is considerably disrupting the US photo voltaic inverter market.
The house battery pack’s built-in inverter is altering the sport.
Tesla acquired its photo voltaic enterprise when it purchased SolarCity in a controversial deal resulting from Musk being a big shareholder of each Tesla and SolarCity, and Musk’s cousin led the latter.
The automaker saved the SolarCity operations going for just a few years. In truth, it continued till after Tesla shareholders sued Musk over the acquisition, and Musk defended himself by claiming that SolarCity had turn out to be an integral a part of Tesla.
Shortly after he received the lawsuit, Tesla just about stopped all operations that got here from its SolarCity acquisition, which primarily consisted of residential photo voltaic financing and installations.
Tesla even stopped reporting photo voltaic deployment. The corporate’s vitality enterprise now consists nearly completely of Powerwall and Megapack deployments.
Nevertheless, the launch of the Powerwall 3 has not directly introduced Tesla again into the photo voltaic enterprise, as the house battery pack options an inverter that works for each photo voltaic and storage functions.
EnergySage is an organization that matches photo voltaic installers with potential consumers, and in consequence, it has a wealth of attention-grabbing information in regards to the photo voltaic trade within the US. As we speak, it launched its Spring 2025 Market report.
Within the report, EnergySage revealed that Tesla turned the second-most quoted inverter model within the second half of final 12 months:
Tesla turned essentially the most quoted battery model in H2 2024, occupying 63% of Market share nationwide. As a result of the Powerwall 3 contains an built-in inverter, Tesla additionally turned the second-most quoted inverter model. With batteries more and more being added to photo voltaic methods—the nationwide battery attachment fee jumped to 45% in H2 2024, an all-time excessive—Tesla’s progress was a key driver of the low storage and photo voltaic costs seen on EnergySage. In 2025, we’re inspecting whether or not model backlash and gear shortages will have an effect on Tesla’s Market share.
That is additionally a byproduct of the elevated reputation of vitality storage methods when deploying new photo voltaic methods.
In large photo voltaic markets like California and Texas, the vast majority of residential photo voltaic quotes are hooked up to batteries, and Tesla just isn’t the highest quoted model, due to Powerwall 3:
Powerwall was already the popular dwelling battery pack for a lot of householders, and the truth that it now features a photo voltaic inverter has made it much more engaging, as most dwelling vitality storage methods within the US are being deployed together with rooftop photo voltaic.
The Powerwall 3’s photo voltaic inverter integration is pushing photo voltaic plus storage prices down fairly a bit.
The recognition of the Powerwall 3 has significantly harm Enphase, a frontrunner in photo voltaic inverter. It had 73% of the US market in 2022, and now it’s right down to 53%.
Regardless of Tesla driving costs down, Powerwall 3 just isn’t the most cost effective battery pack accessible. Panasonic and EG4 batteries had been each priced decrease on a per kWh foundation than Tesla’s within the second half of 2024, however Tesla received on price when additionally changing the photo voltaic inverter.
Nevertheless, it’s not all excellent news from Tesla. EnergySage additionally lately reported a rise in clients requesting alternate options to Powerwalls in 2025, partly resulting from Elon Musk’s growing controversy.
Should you’re concerned with putting in photo voltaic panels and/or batteries in your dwelling, we suggest utilizing EnergySage. It is possible for you to to get quotes with none trouble and solely discuss to somebody if you end up prepared to maneuver ahead. Inside minutes, you may get on the trail to producing your personal energy with photo voltaic and battery storage, together with with Powerwall.
