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.”
Last week, Parker Hannifin launched what they’re calling the industry’s first certified Mobile Electrification Technology Center to train mobile equipment technicians make the transition from conventional diesel engines to modern electric motors.
The electrification of mobile equipment is opening new doors for construction and engineering companies working in indoor, environmentally sensitive, or noise-regulated urban environments – but it also poses a new set of challenges that, while they mirror some of the challenges internal combustion faced a century ago, aren’t yet fully solved. These go beyond just getting energy to the equipment assets’ batteries, and include the integration of hydraulic implements, electronic controls, and the myriad of upfit accessories that have been developed over the last five decades to operate on 12V power.
At the same time, manufacturers and dealers have to ensure the safety of their technicians, which includes providing comprehensive training on the intricacies of high-voltage electric vehicle repair and maintenance – and that’s where Parker’s new mobile equipment training program comes in, helping to accelerate the shift to EVs.
“We are excited to partner with these outstanding distributors at a higher level. Their commitment to designing innovative mobile electrification systems aligns perfectly with our vision to empower machine manufacturers in reducing their environmental footprint while enhancing operational efficiency,” explains Mark Schoessler, VP of sales for Parker’s Motion Systems Group. “Their expertise in designing mobile electrification systems and their capability to deliver integrated solutions will help to maximize the impact of Parker’s expanding METC network.”

The manufacturing equipment experts at Nott Company were among the first to go through the Parker Hannifin training program, certifying their technicians on Parker’s electric motors, drives, coolers, controllers and control systems.
“We are proud to be recognized for our unwavering dedication to advancing mobile electrification technologies and delivering cutting-edge solutions,” says Nott CEO, Markus Rauchhaus. “This milestone would not have been possible without our incredible partners, customers and the team at Nott Company.”
In addition to Nott, two other North American distributors (Depatie Fluid Power in Portage, Michigan, and Hydradyne in Fort Worth, Texas) have completed the Parker certification.
Electrek’s Take

With the rise of electric equipment assets like Bobcat’s T7X compact track loader and E10e electric excavator that eliminate traditional hydraulics and rely on high-voltage battery systems, specialized electrical systems training is becoming increasingly important. Seasoned, steady hands with decades of diesel and hydraulic systems experience are obsolete, and they’ll need to learn new skills to stay relevant.
Certification programs like Parker’s are working to bridge that skills gap, equipping technicians with the skills to maximize performance while mitigating risks associated with high-voltage systems. Here’s hoping more of these start popping up sooner than later.
Based on a Peterbilt 579 commercial semi truck, the ReVolt EREV hybrid electric semi truck promises 40% better fuel economy and more than twice the torque of a conventional, diesel-powered semi. The concept has promise – and now, it has customers.
Austin, Texas-based ReVolt Motors scored its first win with specialist carrier Page Trucking, who’s rolling the dice on five of the Peterbilt 579-based hybrid big rigs — with another order for 15 more of the modified Petes waiting in the wings if the initial five work out.
The deal will see ReVolt’s “dual-power system” put to the test in real-world conditions, pairing its e-axles’ battery-electric torque with up to 1,200 miles of diesel-extended range.

The ReVolt team starts off with a Peterbilt, then removes the transmission and drive axle, replacing them with a large genhead and batteries. As the big Pete’s diesel engine runs (that’s right, kids – the engine stays in place), it creates electrical energy that’s stored in the trucks’ batteries. Those electrons then flow to the truck’s 670 hp e-axles, putting down a massive, 3500 lb-ft of Earth-moving torque to the ground at 0 rpm.

The result is an electrically-driven semi truck that works like a big BMW i3 or other EREV, and packs enough battery capacity to operate as a ZEV (sorry, ZET) in ports and urban clean zones. And, more importantly, allows over-the-road drivers to hotel for up to 34 hours without idling the engine or requiring a grid connection.
That ability to “hotel” in the cab is incredibly important, especially as the national shortage of semi truck parking continues to worsen and the number of goods shipped across America’s roads continues to increase.
And, because the ReVolt trucks can hotel without the noise and emissions of diesel or the loss of range of pure electric, they can immediately “plug in” to existing long-haul routes without the need to wait for a commercial truck charging infrastructure to materialize.
“Drivers should not have to choose between losing their longtime routes because of changing regulatory environments or losing the truck in which they have already made significant investments,” explains Gus Gardner, ReVolt founder and CEO. “American truckers want their trucks to reflect their identity, and our retrofit technology allows them to continue driving the trucks they love while still making a living.”
If all of that sounds familiar, it’s probably because you’ve heard of Hyliion.
In addition to being located in the same town and employing the same idea in the same Peterbilt 579 tractor, ReVolt even employs some of the same key players as Hyliion: both the company’s CTO, Chandra Patil, and its Director of Engineering, Blake Witchie, previously worked at Hyliion’s truck works.
Still, Hyliion made their choice when they shut down their truck business. ReVolt seems to have picked up the ball – and their first customer is eager to run with it.
“Our industry is undergoing a major transition, and fleet owners need practical solutions that make financial sense while reducing our environmental impact,” said Dan Titus, CEO of Page Trucking. “ReVolt’s hybrid drivetrain lowers our fuel costs, providing our drivers with a powerful and efficient truck, all without the need for expensive charging infrastructure or worrying about state compliance mandates. The reduced emissions also enable our customers to reduce their Scope 2 emissions.”
Page Trucking has a fleet of approximately 500 trucks in service, serving the agriculture, hazardous materials, and bulk commodities industries throughout Texas. And, if ReVolt’s EREV semis live up to their promise, expect them to operate a lot more than 20 of ’em.
Fleet electrification expert Tony Nisam took to LinkedIn yesterday to post a deal that he ran across at a Washington State Costco that stacks a $25,500 manufacturer rebate with $3,000 in “regular” Costco Member Savings, $2,750 in “LIMITED-TIME” Manufacturer to Member Incentives, plus an additional $250 for Costco Executive members.
Do a bit of math (add up 25,500 + 3,000 + $2,750 + 250), and you’ll calculate an almost unheard of $31,500 discount on one of the best, most capable commercial vans on the market – ICE or electric. And that’s before you factor in the 0% interest financing (72 mo.) being advertised at Blade Chevrolet, the Mount Vernon, Washington, where VIN 2G58J2TY6S9104313 (the exact van shown, below) is shown as stock number 16757.
If you’re not a Costco member yet and you’re looking for a new truck for your business or even a unique #vanlife ride with zero emissions, modern tech, and a nationwide dealer network, GM makes that $130 Executive membership seem like a no-brainer.
