    It was a typo (none / 0) (#28)

    When I was going through the calculations a second time, I realized that I forgot to multiply by 5 to account for there being 5 panels, not 1. I changed the results accordingly but missed changing the .81 KW to 4.05 KW. The 24.3 KWh is still correct.

    Also, I agree their usage is really high. They should not be running a $14000 electric bill at an office that only operates 5 days a week. Unless, they are running multiple offices with that and several servers or something. I don't know.

    With regard to the 13.5% figure, I used it because I knew that for a 13.5% level of efficiency, you could buy a relatively cheap panel that'll last 25 years ($360/panel), whereas the newer, more efficient panels that get efficiencies between 20%-30% are rather expensive to the point that they might not be the best choice economically. Their prices are still coming down because newer, more highly efficient solar panels* use very recent technology that is becoming cheaper to produce now that they're out of development, but aren't quite as cost-effective as other solar panels yet.

    *I should mention that early high-efficiency solar panels were not cost-effective because they used very expensive materials. The new ones that I'm talking about, however, look like they will be because the materials involved aren't as expensive to produce.
