A South Florida homeowner thought they had finally found a relatively reasonable solar deal until Reddit commenters zeroed in on how Tesla batteries could drive up the cost.
In the thread, the original poster explained that some providers had quoted "$80k and north," making a $59,000 offer for an 18-kilowatt system seem reasonable.
Here's what to know
In asking whether the bid was fair, the homeowner described a package that included labor and hardware, a gateway, one Tesla expansion pack, two Tesla Powerwall 3s, and 40 panels rated at 440 watts each. They would pay city permit costs separately.
The discussion centered on the battery hardware. Commenters said the figure did not appear unusual for a Tesla-based installation.
"Half of that price is the PW3's material cost. … The total price is actually low for Tesla hardware installed by a legitimate Tesla-certified installer," one Reddit user wrote.
For this homeowner, though, Tesla was not a brand preference. They said utility approval and net metering with Florida Power and Light made alternatives hard to justify.
"I would, but in order for it to remotely break even in South Florida, I need to take advantage of net metering," the homeowner replied. "Contractors are pushing equipment that's more readily recognizable and easily approved by FPL. I've looked into Franklin and Anker, but one was same price point and the other does not net-meter."

More background
The higher quotes showed that equipment, storage, and configuration choices can swing pricing by tens of thousands of dollars.
Battery storage can be valuable, but it can also be expensive. In a storm-prone state such as Florida, backup power and a measure of energy independence can be especially appealing, but they can also lengthen the payback period if the system is oversize or tied to premium hardware.
After accounting for a tax credit, the homeowner estimated a break-even timeline of 10 years.
Some commenters questioned that math, but one person argued, "You only need to save $30k to break even; you are still paying for electricity every month without solar."
