I have a two panel system, and the panels are about 430 watts each. Given the current ToD rates for electric, it will take years to pay back.

Microinverter: 400 Panels (used): 250 for both Cables: 50

I also picked up two LiFePo4 batteries and two Kasa smart plugs and time shifted my computing infrastructure's electricity usage. That made much more of a difference in my bill, since a few hundred watts moved to .09/kwh. If the bms was smarter i could charge the batteries with solar, but alas i can't cap the recharge current.
