Cat herder, and dog toy tosser.

I made a layout this afternoon on the roof with a cardboard template. I will have about a 1-foot gap between two rows of 5 and a row of 2.
I plan to have 2 strings of 3s X 2p (12 total panels, 3.5 kWp), 120VDC will work with my 60-115V MPPTs. (MPP Solar LV5048, x2, 4 total MPPTs, 4000w capable each/16kW of possibility!)
I have 6.2 kWp of SolarEdge grid-tied. That I waisted an enormous amount of money on. Had I done this "DIY" I would have saved a great deal of money, just to blow on more battery banks. ?

- 295w used solar panels (I've seen 248w from them already! They are polycrystalline, big and heavy, way overbuilt for residential use.)
- Superstrut
- Lowes
- Threaded rod hangers (Sammys 3/8-16 for wood)
- Bolts to hold the Superstrut to the Threaded Rod hangers
- 3/8 washers 316SS for bolts to hold the Superstrut to the Sammy
- X-Large Rubber Fender washers (Helps seal the roof and a gap between the steel and the aluminum)
- Bolts to hold the panels to the Superstrut
- Fender washers to hold panels
- Spring Nuts for Superstrut (so the bolt holding the panels to the strut have something to tighten with)
- 8AWG outdoor PV cable for the panels. (10 would work fine, but it's cheap so why not?)
- Missouri Wind and Solar
- The only 8AWG wire stripper I could find
- MC4 Connectors
- MC4 Branch Connectors (AKA "Y" (WYE) connectors/2 to 1 connector/Parallel Connectors)
- PVC Box for the circuit breakers to live in
- Lowes
- DC 40 AMP/150V circuit breakers (DC circuit breakers act as on-off switches also, DO NOT USE AC Circuit breakers for DC loads, they are different)
- Din Rail mount for DC Circuit Breakers
- Roof Sealant
