Switching to Solar

[ReddingNetwork]

Hi There I am running a remote camera site as seen below.

1ea. WS-6-MINI Switch
1ea. PA-50V-65W Power supply
1ea. NBE-M5-19 5GHz NanoBeam M5 19dBi
2 ea. Cameras LTS Platinum Fixed Lens Bullet Camera 4.1MP - 4mm CMIP9142W

The total wattage is about 25 to 30 Watts

This site has power from 8PM to 6AM daily. ( Site is attached to a lighting circuit that is on a timer )
The site runs great at night but now we need to run it 24/7/365

I am trying to find the most cost effective approach to do this.
1. Solar only 2 panels running at 24V DC with 2 batteries and a controller, Remove the current power supply and connect directly to battery
2. Solar with a grid tie 2 panels running at 12V with 1 battery, a controller, and a 12 Volt DC to 110 Volt AC inverter
3. Go to a WS-8-150-DC and replace the WS-6-MINI ( Not sure the voltage needs for this? )
or any other options...

Any help would be appreciated
Thank You.

I would combine 1 and 3. The WS-8 needs between 9 and 60 volts or there about so a 24V system would give you plenty of margin.

Why bother with solar panels? Go with a modified version of #2 - Just put in a couple of properly sized batteries and a charger... charge at night, run all day on battery. Just be sure to do the load and run-time calculations in reverse (i.e. how long is the average day vs. with solar where it is how long is the average night). As I recall, these things are more efficient at 24V (although we have done 12V).

If you want to go off-grid, solar panels do provide a nice way to shade the equipment cabinet...
