A Hyundai Ioniq 5 owner in Southern California orchestrates his home’s energy consumption, running a Level 1 charger for six hours daily, adjusting AC charging rates, and balancing a 15 kWh home battery, all to avoid selling excess solar power back to the grid at a paltry $0.025 per kilowatt-hour.025 per kilowatt-hour. This elaborate dance, producing 50 kWh a day, is not about efficiency; it’s about survival in a utility landscape that actively disincentivizes renewable energy production. The core problem is clear: utility companies are making it economically punitive for homeowners to contribute to the grid.
This is a direct consequence of shifting net metering policies, particularly in states like California. When utilities pay a fraction of what they charge for electricity, homeowners with solar panels and EVs are forced into complex, real-time energy management strategies to extract any value from their investment. This systemic disincentive for distributed generation undermines the very premise of a greener energy future.
The current utility buy-back rates in California are forcing Ioniq 5 owners with solar to become full-time energy managers, rather than partners in grid decarbonization.
“Love to hear how those of you with solar panels maximize charging your EV.
Selling electricity back to the grid has a terrible rate (around $0.025/kWh), so I try to use all of my solar generation for myself. I have tried all the different strategies where I can generate about 50 kWh a day this time of year and have a 15 kWh home battery. I generally use my Level 1 charger at 1.7 kW starting around 10:30 AM and run it till around 4:30 PM. This allows me to cover all my house, electricity, fully charge my home battery, and charge my I5 simultaneously. If I need to charge more in a short period of time, I will use my Level 2 charger that peaks around a 9.2 kW rate and adjust the AC charging rate from my I5 as may be needed. For example, if my home battery is at least 85% charged and I’m producing around 6 kW per hour, I can adjust my charging rate to 60% and only pull about .8 kW off my home battery to get more of a charge into my car. If I’m really in need, I go full charging rate and maybe pull 4 or 5 kWh from my home battery. For me, my rate is very low for Southern California between midnight and 6 AM, so I really just need my home battery to get me to midnight.
How do you all manage your solar with charging your EV?”
His detailed description of balancing a 1.7 kW Level 1 charger, a 9.2 kW Level 2, a 15 kWh home battery, and his house’s load, all while monitoring 50 kWh of daily solar generation, paints a stark picture of the hoops EV owners must jump through.
Hyundai Ioniq 5: EV Charging Optimization
This level of granular control is a necessary defense against utility policies designed to benefit the utility, not the consumer or the environment.
The fact that an owner must consider whether to pull 0. Using 0.8 kW or 4-5 kWh from a home battery to avoid selling back to the grid shows the absurdity of the current compensation structure. This is about energy avoidance when dealing with the grid. The question then becomes: why are utilities allowed to pay so little for power that they then resell at a significant markup?
Facebook user David Lavigne, from Colorado, shows a dramatically different scenario, stating: “In Colorado, we have net metering and time of use. It’s cheaper to charge at night and sell the energy back during the day. We get $150 a year to let Xcel control our charging at night, which at 8c/kw is 1875kw for free.”
David’s experience in Colorado, where Xcel Energy offers a $150 annual incentive for controlled night charging and pays a reasonable 8 cents per kWh for surplus, stands in stark contrast to California’s predatory rates. A 9.3 kW solar array owner with 31 panels in Pittsburgh highlights the regional discrepancy, stating: Colorado’s approach encourages participation, while California’s actively discourages it, turning solar owners into reluctant energy hoarders. The disparity reveals a clear choice utilities are making: to collaborate with or exploit their solar-generating customers.
Mike Doughney, commenting on David Lavigne’s post, correctly identifies the core issue for California residents: “David Lavigne The OP is in California, where you’re paid a fraction of what you’re paying for grid power, for whatever surplus you return to the grid. In that case, it makes more sense to soak up whatever your panels are producing into your car or battery whenever possible, outside of the midnight-6 am bracket.”
Doughney’s analysis confirms the Ioniq 5 owner’s strategy is a rational response to an irrational market. The midnight-6 AM window, where rates are low, becomes the only viable time for grid interaction, turning the home battery into a buffer to reach that period. This effectively makes the home a microgrid, but one that is constantly battling the macro-grid’s punitive pricing. It begs the question: if utilities are so keen to push EVs, why are they simultaneously making it harder for EV owners to use renewable energy to power them?
Adel Assaad, an 11. This is a regional difference and a fundamental philosophical divide in how utilities view distributed generation. “What electric utility is this? Duquesne Light offers time-of-use rates, and generally, even in “sunny” Pittsburgh, they offset my electric bill March-November, including EV charging, two central air systems, and one heat pump water heater. They also offer time-of-use rates, with the peak between 3 pm and 9 pm weekdays only. Very expensive then, but this has been sufficient to make me not think about anything other than batteries to offset the peak (very expensive).”
Assaad’s experience with Duquesne Light in Pittsburgh, where time-of-use rates allow for significant bill offset even with heavy EV and HVAC usage, reveals the point. The peak pricing between 3 PM and 9 PM is a standard utility strategy, but the structure still allows for economic benefit from solar. This is a far cry from the Californian scenario, where the buy-back rate is so low it forces active avoidance. The technology exists to integrate solar and EVs seamlessly; the barrier is purely regulatory and economic, dictated by utility companies.
The detailed energy management strategy employed by this Hyundai Ioniq 5 owner is a symptom of a fundamentally broken utility policy. When homeowners must actively work to avoid selling clean energy back to the grid, the system has failed. California’s low solar buy-back rates are a disservice to its residents and a significant roadblock to true energy independence and decarbonization, forcing consumers into a complex and unnecessary daily battle with their own power company.
