My 215 watt kyocera panel buy was just a small portion of the total spend.

It's like that with any electrical upgrade.... Try installing a high output alternator. The proper fusing, wiring, pulleys, brackets, nuts bolts and various other accessories will usually cost more than the alternator itself.. Hell a serpentine pulley kit to drive a 100+ amp alt runs about $700.00 alone....
But hey the price of solar has come waaaaaaay down. I just recently ordered two Kyocera 140's for a customer and including shipping it was less than $600.00 for both 140W panels... In fact I treated myself to a new Kyocera 140 a few weeks ago as the price was ridiculously low. We nearly doubled my solar capacity and the bank now goes from where the alt left off to 100% SOC in less than two days.
For about $500.00 or less you can get a pretty sweet solar set up these days.
The ROI really comes down the road. Our 375Ah $210.00 Wal*Mart battery bank is still purring along perfectly in its sixth season. They still test at 96-98% of new. Next year will be year seven and most of this success is due to the addition of solar for our mooring sailed vessel..
