Today it appears that the rumors about Tesla revising its referral program were true: As of September 18, 2021, Tesla is no longer offering any referral incentives on the purchase of Tesla cars or traditional solar panel systems. The only Tesla product that still benefits from a referral discount is the Tesla solar roof. As of today, buyers of a Tesla solar roof who use a Tesla referral code can still get $500 back after installation. The referring customer will also receive a $500 referral bonus after the system is installed. But the previous bonus of free supercharging miles for car purchases or leases is no longer in effect.
As of today, the only Tesla product eligible for a Referral bonus is the Tesla solar roof.
As with many Tesla “announcements,” there wasn’t one. Tesla simply changed the terms of the referral program on their web site without notice. The change comes just one week after Tesla increased the referral bonus for the purchase of any Tesla solar system from $100 to $500. It remains unclear why Tesla has increased the referral bounty of solar roof systems when the company has also recently stated that they are having trouble keeping up with demand for the PowerWall – Tesla’s home battery. As of April of this year, all Tesla solar systems (solar roof and traditional solar panel systems) require the purchase of one or more PowerWalls as part of the system.
The benefits of combining a large battery with a solar power system are significant: customers can save money and reduce strain on the grid by shifting their electricity usage from peak hours to off-peak hours. During peak usage hours, customers can draw electricity from the PowerWall instead of from the grid. They can then recharge the PowerWall from solar or from the grid during off-peak hours when power is cheaper. A PowerWall or two can also help provide continuous power to a customer during a blackout. Rather than installing a diesel or natural-gas powered backup generator, PowerWall owners can draw power from their own batteries and recharge those batteries from their solar panels until grid power is restored. But a PowerWall is still fairly expensive – currently $6,500 for the battery and $4,000 for additional hardware and installation. Current generation PowerWalls store around 13 kWh of electricity, which may not be enough capacity, depending on the length of the power outage. In some cases, Tesla recommends that multiple PowerWalls be installed to provide more backup power.

As for the referral program changes, Tesla has previously hinted that a new version of the referral program for car purchases could be coming at some point in the future, one that required more direct involvement and interaction between referrer and buyer. A new referral program may even require that the prospective buyer schedule a test drive in order to qualify for a referral bonus. Apparently the free supercharging perk of the previous referral program cost Tesla millions of dollars in the first quarter of this year, and the company may believe that the mechanism of the current referral program is too simple: click a link, get a bonus. By making the referral mechanism a little more complicated or labor intensive, Tesla may hope to be able to continue to offer an incentive to existing customers and to new buyers when a personal referral and connection is actually made. Tesla has not yet revealed any official details on a revised referral program for automobiles or traditional solar power systems.
Enphase Energy just launched a new off-grid system that lets homeowners power their homes without a utility connection – even for extended periods. The California-based Enphase says the off-grid setup delivers a seamless way to live independently from the grid while still using solar, batteries, and a standby AC generator.
A full off-grid setup
The new system combines Enphase’s IQ Battery 5P with embedded grid-forming microinverters, IQ8 Series Microinverters with Sunlight JumpStart, and a third-party standby AC generator. The components work together to supply power to a home and automatically manage energy sources to maximize efficiency and reliability.
If the batteries are drained and the generator runs out of fuel, the Sunlight JumpStart feature can automatically recharge the batteries the next morning once the sun comes up.
The IQ Battery 5P delivers 3.84 kVA of power per 5 kWh of capacity, and systems can be scaled up to 40 kWh and 15.4 kVA. That’s enough power to start big household appliances like HVAC systems or water pumps. The IQ System Controller 3G provides the backbone, managing solar, batteries, and generator inputs to deliver up to 46 kVA of off-grid power.

Smarter control and connectivity
Each system connects to the cloud through Enphase’s IQ Combiner 5C HDK, which bundles solar interconnection, communications, and metering into one box. For homes without reliable broadband, the built-in 4G LTE Cat 4 modem keeps the system online for monitoring, firmware updates, and remote support.
Homeowners can manage everything from the Enphase App – from solar generation and battery status to generator integration and load control.
Why it matters
As grid outages become more common and homeowners look for ways to gain energy independence, off-grid systems like this are becoming more appealing.
“With the launch of our off-grid solution, we are giving homeowners a reliable path to complete energy independence,” said Nitish Mathur, Enphase’s SVP of customer experience. Enphase says over 100 homes are already operating entirely off-grid using its technology. The company plans to expand availability beyond the US in 2026.

Global offshore wind targets are still strong enough to triple global capacity by 2030, despite the US’s offshore wind stagnation under Trump. A new analysis from energy think tank Ember and the Global Offshore Wind Alliance (GOWA) shows that the rest of the world is charging forward, underscoring confidence in offshore wind as a cornerstone of future clean energy systems.
Based on the latest NHTSA report, Tesla’s ‘Robotaxis’ keep crashing in Austin, Texas, despite ‘safety monitors’ preventing an unknown number of crashes.
Under an NHTSA Standing General Order SGO, automakers are required to report crashes involving their autonomous driving (ADS) and advanced driver assistance systems (ADAS) within five days of being notified of them.
For years, Tesla was only reporting ADAS crashes, since, despite the names of its Autopilot and Full Self-Driving systems, they are only considered level 2 driver assistance systems.
Since the launch of the Robotaxi service in Austin, Texas, where Tesla moved the supervisor from the driver’s seat to the passenger seat, it has now reported its first few crashes under the ADS reporting.
This week, NHTSA has updated its crash report and revealed a 4th crash that happened in September:

As we previously highlighted, when it comes to both ADS and ADAS crash reporting, Tesla abuses the redacting capacity and hides most information about its crashes, unlike most of its competitors.
Therefore, we don’t have much information about this new crash, but it reportedly occurred in a parking lot and involved a Tesla Robotaxi crashing into a “fixed object,” resulting in property damage.
What’s most interesting about this crash is that it comes as Tesla released the first bit of data about its Robotaxi program in Austin.
During its earnings call last week, Tesla confirmed that the Robotaxi fleet has traveled 250,000 miles since its launch in late June.
Therefore, Tesla Robotaxi currently crashes at a rate of about once every 62,500 miles. That’s with a safety monitor with a finger on a kill switch, ready to stop the vehicle at all times.
We have no data on how often Tesla’s safety monitors prevent crashes in its robotaxis.
For comparison, the NHTSA report lists 1,267 crashes involving Waymo vehicles. However, Waymo’s robotaxis have covered over 125 million fully driverless miles since inception. That’s a crash every 98,600 miles and without any onboard safety monitor.
Electrek’s Take
That’s the problem with comparing Tesla and Waymo.
At least we can now clearly see that Waymo’s incident rate is much lower than Tesla’s, but that’s with a safety monitor in Tesla robotaxis that prevents an untold number of crashes.
The actual difference could be 10x higher. We simply don’t know. Tesla has always refused to share any data regarding disengagement or intervention rates.
One thing is clear: Tesla is way behind Waymo in autonomous driving safety.
