Hello, I'm new to this.
I`m looking to set up a backup system that will run five Goal Zero 4.5 watt lights (light a life 350) at their full brightness for 4 hours per night. Plus run my laptop which has a 19V battery at 3.42A (so it I guess it draws 65 watts per hour?) for 4 hours per night. Note: The panel or panels will be set up with only a 10% camber (nearly flat) and facing southwest (I can`t change this- long story).
I have one KingSolar 120 Watt Solar Panel (link)
I`m trying to figure out:
- How big a battery do I need? Any specific recommendations?
- How many 120W panels do I need to be able to recharge the battery enough throughout the day for the stated nightly usage?
- What`s a good quality Charge Controller that can handle all of this?
If you have any other advice or tips or reading recommendations so I can learn more about all this that would be great! Thanks
