Thanks for the replies Joel
1) All of the components look good except the battery tender. I assume that you will be using the battery tender to keep the batteries at full charge during the evening hours? If so, you only want to use the tender during the evening hours and never during the daylight. If using the tender simultaneously with the PV panels, possible to over-charge the batteries. To play it safe on the tender, I would recommend to plug the tender charger into a timer and only have it top-off the batteries during evening hours.
2) You will also need a roof mount or a pole mount to mount the panels. The mounts are always made of metal and need to be grounded using an Inter-system bonding device at your existing ground rod near your electrical meter socket. The equipment grounding conductor needs to be sized as 10 AWG Copper.
3) Code also requires a safety disconnect switch located on the exterior of the home prior to the cables being routed into the house. Since each panel is rated @ 8.28 amps, you could purchase an air conditioning disconnect switch (non-fusible type) 30 amp rated, 2 pole and weatherproof type that would be able to cut power from the PV's for any maintenance and/or safety reasons.
4) The 2 batteries will be installed in parallel for a 12 VDC output. You also need 2 plastic battery cases to protect the batteries.
5) Depending upon the distance from the PV's to the battery bank, you may want to consider increasing the cable size from 10 AWG to 8 AWG due to any voltage drop. I would need to know the approximate distance in order to calculate the voltage drop.
6) You will also require a combiner box or weatherproof junction box (NEMA 3R rated) for combining the PV cables on the exterior.
7) If you will be grid tied to your main electrical panel, let me know.
