Google search, should find plenty of information. There are solar charging phone chargers/battery packs, with good capacity, which can power anything using a USB port. Not sure how weatherproof, but possible cheap/simple solution, considering the small space, only used for a short time (hunting season). There are USB lights and desk fans.
A permanent installation, best to start of with your needs and usage, how much power, and how long (couple hours/all day or night), watt-hours. Then you choose a battery size, that will cover your needs. Charging is usually 10% of the capacity current, but you have to take into consideration how much direct sunlight/cloud cover you have at the location. You'll also want a charge controller, to protect your battery (expensive), and maximize the output of your panels. You want one that shuts off the output to your devices, before the battery is completely depleted. Batteries are expensive, 7Ah sealed lead-acid is about $25, powers my back porch led lights for 3-4 hours. The lights were off a truck my brother scrapped once, pretty bright. Battery isn't strong enough to run even a 70 watt inverter. Have single 15 watt panel charging it, on my second battery, over 12 years now. We had a bad hurricane season in 2004, wanted to install enough solar to run a coffee maker, but never got around to it. Need a pretty large battery.
