Other than yes, I’ve installed ours, your question is difficult to answer for several reasons, discounting the savvy of who’s installing the panel, and the romantics of green energy.
Here are some questions you, or anyone, should answer prior to any purchase.
Battery capacity, amps consumed on the average and at peak, frequented locations—north or south US – wooded areas, valley areas whereby shadows occur, angle of the sun in other words. Further, does your panel tilt or is it flat on the roof, obstructed or clean? Do you have a controller, or do these panels require additional monitor systems? If you have more than one, do you require diodes to restrict feeding the solar cells in the evening, while in the shade, or a bad cell when you are on battery power. Are you restricting or limiting AC to your units?
Anyway, you get the drift, I’m sure. However, most often folks under-size cell installations, which means spending a ton of money for little effect.
I hope this helps,
