After using artificial intelligence to sketch out an off-grid solar build, a Michigan homeowner brought a revised version of the plan to the "r/solar" subreddit to see how it would hold up under outside scrutiny.
While their first Gemini-produced draft drew some backlash, the new plans mostly passed muster.
Here's what to know
In a Reddit thread, the homeowner described an off-grid setup for a 2,300-square-foot house with a basement built around an EG4 18k inverter, two EG4 PowerPro wall batteries, and 30 Atlas panels rated at 550 watts each.
For heating, the plan relied on a pellet stove, with the furnace set to fan-only mode to move air, while mini-splits were intended for summer cooling.
At about 16.5 kilowatts of solar, the proposed array was large for a residential system. Even so, commenters focused less on panel count than on whether the battery capacity and heating approach could make it through Northern Michigan's long, overcast winter periods.
For homeowners weighing a similar move, going solar is one of the best ways to save money on home energy. You can try EnergySage to get free solar installation estimates and compare quotes.
More background
Much of the feedback shifted away from sheer generation and toward what would happen when conditions got tougher.
"30 panels at 550W is a beefy setup, that should cover a lot even with northern winters being what they are," a user observed. "The pellet stove with the furnace on fan-only is a smart way to reuse existing ductwork, and the mini splits will sip power compared to central AC."

In cold climates, heating is often the hardest part of the energy equation. Comfort and operating costs still depend heavily on how well warm air moves through the house and how much backup capacity is available. Most posters' concerns related to the latter.
Solar can lower utility bills, reduce dependence on volatile energy prices, and keep key home systems running more reliably, but only if the system is sized for real-world conditions, not ideal ones.
People are also turning to online communities to test AI-assisted planning before committing money. In this case, commenters raised questions about load shedding, generator sizing, and propane as part of the backup strategy.
