I have 38 panels with the goal of producing 106% of my electricity usage.

^^^ Just curious, what is the size of each panel (how many feet wide by how many feet long)?

Also, when I think about solar I often wonder how long will they last? Are they guaranteed for a number of years?  What potential costs would there be for repairs and maintenance?  I live up north, but if I lived in FLA like some of you guys I'd worry about a hurricane ripping them off; would they be covered by homeowners' insurance?  Any additional insurance cost to cover them?  I wonder if ones sold up north have a mechanism to melt the snow off of them after snowstorms?  It seems you would want to have a pretty new roof before you install them, otherwise I think it would be a hassle to remove them to install a new roof, this could add to cost if you decide to replace your roof earlier than necessary.

Snow melts off of them pretty quickly.
I have 20 panels and they're these:
HANWHA 400 (Q.PEAK DUO BLK ML-G10.a+ 400)

400 watt rated 1.8m x 1m in size

Not sure about the insurance issues, but longevity is not something that is a big issue even for normal panels (if you got some off aliexpress, well, who knows). Mean degradation is around 0.5% per year. That is, your peak output is still 90% of "new" after 20 years.

The system isn't entirely zero-maintenance (what is) and one of the bigger issues is the inverter which typically has a lifespan of 10-15 years. (There are different configurations, such as using "microinverters" for each panel individually, that last considerably longer - upsides and downsides to everything, so the best solution varies by use case.)

The cost of a new inverter is cheap compared to a total install, but not exactly *cheap*. For an install size like Fau's, we're talking several thousand dollars (last I checked, anyway).

As an update, I used 439 KWH last month, and after 10 days i've generated 321 KWH using solar, so i'm on a pretty good pace to break even for the year (last august I used 1300 KWH because of the central AC)

Over my 30 day cycle, I have generated 1142 kWh.  I don't know what I've used or what the bill will look like.  I think I probably will have some spillover from before so I don't expect to have an answer until the NEXT bill after this one.

Check this out. Maybe adding solar and wind power together could do the trick.

In CA, we have a grid connection fee that makes the minimum electric bill around $20.  Do you have something similar?

That bill makes absolutely no sense.
Which numbers do you add to get to $36.55?

If I am reading it correctly 31.97 is a subtotal of everything above it   31.97 + everything below is 36.55.  but that is just eyeballing did actually do the math.

Edit taxes are also listed and subtotaled

^ seems legit

I don't know why "base charge" or "minimum base bill charge" are separate line items or what they represent.

I'm just guessing, but it seems like the actual electricity cost is the $11.73 and the $4.00.  My minimum possible bill is probably around $20.
