When Josh Hurwitz decided to put solar power on his Connecticut house, he had three big reasons: To cut his carbon footprint, to eventually store electricity in a solar-powered battery in case of blackouts, and – crucially – to save money.

Now he’s on track to pay for his system in six years, then save tens of thousands of dollars in the 15 years after that, while giving himself a hedge against utility-rate inflation. It’s working so well, he’s preparing to add a Tesla-made battery to let him store the power he makes. Central to the deal: Tax credits and other benefits from both the state of Connecticut and from Washington, D.C., he says.

“You have to make the money work,” Hurwitz said. “You can have the best of intentions, but if the numbers don’t work it doesn’t make sense to do it.” 

Hurwitz’s experience points up one benefit of the Inflation Reduction Act that passed in August: Its extension and expansion of tax credits to promote the spread of home-based solar power systems. Adoption is expected to grow 26 percent faster because of the law, which extends tax credits that had been set to expire by 2024 through 2035, says a report by Wood Mackenzie and the Solar Energy Industry Association. 

Those credits will cover 30 percent of the cost of the system – and, for the first time, there’s a 30 percent credit for batteries that can store newly-produced power for use when it’s needed.

“The main thing the law does is give the industry, and consumers, assurance that the tax credits will be there today, tomorrow and for the next 10 years,” said Warren Leon, executive director of the Clean Energy States Alliance, a bipartisan coalition of state government energy agencies. “Rooftop solar is still expensive enough to require some subsidies.”

California’s solar energy net metering decision

Certainty has been the thing that’s hard to come by in solar, where frequent policy changes make the market a “solar coaster,” as one industry executive put it. Just as the expanded federal tax credits were taking effect, California on Dec. 15 slashed another big incentive allowing homeowners to sell excess solar energy generated by their systems back to the grid at attractive rates, scrambling the math anew in the largest U.S. state and its biggest solar-power market — though the changes do not take effect until next April.

Put the state and federal changes together, and Wood Mackenzie thinks the California solar market will actually shrink sharply in 2024, down by as much as 39%. Before the Inflation Reduction Act incentives were factored in, the consulting firm forecast a 50% drop with the California policy shift. Residential solar is coming off a historic quarter, with 1.57 GW installed, a 43% increase year over year, and California a little over one-third of the total, according to Wood Mackenzie.

For potential switchers, tax credits can quickly recover part of the up-front cost of going green. Hurwitz took the federal tax credit for his system when he installed it in 2020, and is preparing to add a battery now that it, too, comes with tax credits. Some contractors offer deals where they absorb the upfront cost – and claim the credit – in exchange for agreements to lease back the system. 

Combined with savings on power homeowners don’t  buy from utilities, the tax credits can make rooftop solar systems pay for themselves within as little as five years – and save $25,000 or more, after recovering the initial investment, within two decades.  

“Will this growth have legs? Absolutely,” said Veronica Zhang, portfolio manager of the Van Eck Environmental Sustainability Fund, a green fund not exclusively focused on solar. “With utility rates going up, it’s a good time to move if you were thinking about it in the first place.”

How to calculate installation costs and benefits

Here is how the numbers work.

Nationally, the cost for solar in 2022 ranges from $16,870 to $23,170, after the tax credit, for a 10-kilowatt system, the size for which quotes are sought most often on EnergySage, a Boston-based quote-comparison site for solar panels and batteries. Most households can use a system of six or seven kilowatts, EnergySage spokesman Nick Liberati said. A 10-12 kilowatt battery costs about $13,000 more, he added.

There’s a significant variation in those numbers by region, and by the size and other factors specific to the house, EnergySage CEO Vikram Aggarwal said. In New Jersey, for example, a 7-kilowatt system costs on average $20,510 before the credit and $15,177 after it. In Houston, it’s about $1,000 less. In Chicago, that system is close to $2,000 more than in New Jersey. A more robust 10-kilowatt system costs more than $31,000 before the credit around Chicago, but $26,500 in Tampa, Fla. All of these average prices are as quoted by EnergySage. 

The effectiveness of the system may also vary because of things specific to the house, including the placement of trees on or near the property, as we found out when we asked EnergySage’s online bid-solicitation system to look at specific homes.

The bids for one suburban Chicago house ranged as low as $19,096 after the federal credit and as high as $30,676.

Offsetting those costs are electricity savings and state tax breaks that recover the cost of the system in as little as 4.5 years, according to the bids. Contractors claimed that power savings and state incentives could save as much as another $27,625 over 20 years, on top of the capital cost.

Alternatively, consumers can finance the system but still own it themselves – we were quoted interest rates of 2.99 to 8.99 percent. That eliminates consumers’ up-front cost, but cuts into the savings as some of the avoided utility costs go to pay off interest, Aggarwal said. 

The key to maximizing savings is to know the specific regulations in your state – and get help understanding often-complex contracts, said Hurwitz, who is a physician.

Energy storage and excess power

Some states have more generous subsidies than others, and more pro-consumer rules mandating that utilities pay higher prices for excess power that home solar systems create during peak production hours, or even extract from homeowners’ batteries.

California had among the most generous rules of all until this week. But state utility regulators agreed to let utilities pay much less for excess power they are required to buy, after power companies argued that the rates were too high, and raised power prices for other customers.

Wood Mackenzie said the details of California’s decision made it look less onerous than the firm had expected. EnergySage says the payback period for California systems without a battery will be 10 years instead of six after the new rules take effect in April. Savings in the years afterward will be about 60 percent less, the company estimates. Systems with a battery, which pay for themselves after 10 years, will be little affected because their owners keep most of their excess power instead of selling it to the utility, according to EnergySage. 

“The new [California rules] certainly elongate current payback periods for solar and solar-plus-storage, but not by as much as the previous proposal,” Wood Mackenzie said in the Dec. 16 report. “By 2024, the real impacts of the IRA will begin to come to fruition.”

The more expensive power is from a local utility, the more sense home solar will make. And some contractors will back claims about power savings with agreements to pay part of your utility bill if the systems don’t produce as much energy as promised. 

“You have to do your homework before you sign,” Hurwitz said. “But energy costs always go up. That’s another hidden incentive.”

Tesla and Rivian are settling their battery tech theft lawsuit

Tesla and Rivian are settling their battery tech theft lawsuit

Tesla and Rivian have been embroiled in a lawsuit in which the former accused the latter of having stolen battery technology by poaching Tesla employees.

It sounds like the two automakers are finally about to settle the lawsuit, which has been going on for 4 years.

In 2020, Tesla filed a lawsuit against Rivian over allegedly stealing trade secrets by hiring former Tesla employees and encouraging them to bring documents. Rivian has denied the allegations.

When Tesla filed the lawsuit, it wasn’t clear what trade secrets Tesla was claiming Rivian had stolen. However, we noted that the employees listed in the lawsuits were two recruiters, an EHS manager, and a manager of Tesla’s charging networks.

The automaker claimed that these employees brought “documents consisting of highly sensitive trade secret, confidential, and proprietary engineering information” when they went to work for Rivian.

A year later, Tesla expanded the lawsuitclaiming more specifically that Rivian was “stealing the core technology for its next-generation batteries.”

At first, the companies tried to settle out of court, but it didn’t work out, so the lawsuit was moved to court last year.

Over a year later, we now learn that Tesla had notified the court that it expects to file to get the lawsuit dismissed after reaching a conditional agreement with Rivian. The company didn’t disclose the details of the settlement (via Bloomberg):

Tesla didn’t disclose specifics about the agreement in a court filing, but told a California state judge that it expects to seek dismissal of the case by Dec. 24 upon satisfactory completion of the terms.

Neither Tesla nor Rivian have commented on the reported settlement.

While Tesla has claimed that it somewhat open-sourced its patents, we have previously noted that it’s not exactly the case. Tesla claims to let other companies use its patented technology as long as they themselves don’t sue them over patent rights.

And in this specific case, Tesla alleges that Rivian has specifically hired employees to steal technologies. Again, Rivian has denied the allegation.

Electrek’s Take

The terms are unknown, but in similar cases, it often involves things like some level of access to make sure that no proprietary technology is being used or has been used.

The lawsuit is not exactly clear, but based on the timeline and the allegations of “next-gen batteries”, Tesla could have been talking about its 4680 battery cells, although those are cells. It could also be the structural battery pack.

Rivian is expected to use a taller 4695 battery from LG Energy Solutions for its next-generation vehicles.

Kempower, Proviridis partner on novel electric semi truck charging solution

French infrastructure specialists Proviridis have partnered with EVSE manufacturer Kempower to deliver a novel, underground charging solution for electric semi trucks designed to easily integrate into existing truck depots.

By installing its high-powered charging cabinets underground and integrating the charging cables into a solid metal pipe, Kempower and Proviridis have been able to make room for high-powered charging points in an existing truck depot that didn’t have enough space to install either conventional EVSE or overhead “drop lines.”

For the pilot, the metal pipe is painted in a striking yellow color to make it easier to see while maneuvering the lot, and keeping the dispensers themselves more protected than conventional concrete bollards. The 600 kW power cabinet is positioned a few yards away – a typical space-saving Kempower solution – and connected to the charge points by underground cable.

Proviridis believes their solution provides enough of a competitive advantage that fleet buyers looking to electrify will be eager to give it a try.

“The product is durable across a wide spectrum of temperatures and conditions, requires minimal ventilation, and can cater for a wide range of customer needs,” explains Olivier Verdu, Technical Director at Proviridis. “These are features which perfectly place the Kempower solution for this type of charging configuration in a logistics environment.”

Electrek’s Take

While traditional charging equipment can cause up to 20% of an existing truck depot’s parking capacity to be lost, the Kempower products have already gained recognition for the efficient size footprint of its overground Satellites. If this underground version proves to be even better, you can expect to see a lot more Kempower installations near you.
