I manufacture battery based systems. One of the other advantages to a battery based system is they continue to work when the utility is down. Straight to Grid systems shut down when the utility power is out.
As far as maintenance, the new batteries we use are good for 3000 cycles at 50% depth of discharge. At one cycle per day, they should last 8.9 years. They are sealed batteries so no maintenance. Charging system prevents off-gassing.

It will happen every night. 25 panels *310 Watts/panel = 7750 Watt array. In your location, the AVERAGE power produced per day will be around 46.5 kWh. I know you don't have too many cloudy days. But the power output will vary summer/winter. Winter will average about 30 kWh/day and summer will be about 60.
See the light blue line for standard fixed solar tilt. This chart is for an area with 5kWh/day production. You would shift the chart up, one kWh/day
Monthly value @ $0.20/kwh
Summer=$360
Winter=$180
Spring/Fall=$280
Yearly savings =$3400
