Solar Panel

[Maxable]

So I'm debating some power options for my non-hydro annual camp site. The Champion generator I have is just rude. I see that Harbor freight has a 45W solar panel kit (3 15W panels) for $149.99. Since I can't afford a Honda generator, will this solar panel keep my battery topped up if I go to the trailer once or twice a week? My site is partially wooded so may not get a full day of sun. Will I need to buy anything else or just wire straight to battery? Thanks

I think it all depends on what you are going to be using for electricity when you are there. If you will just be using lights "sparingly', and the water pump "sparingly", you might get by. If you will be needing to run the furnace very much that's a different story. The furnace fan takes a lot of amps.
Another thing is what have you got for a battery bank? You will have your best results from at least two 6 volt deep cycle batteries. Call harbor freight and ask them what all comes with that set up, and if you need anything else for it. I'm not sure if it needs a charge controller or not.
I have a 135 watt panel on the roof and a charge controller panel mounted inside the camper, and two T105 6 volt Trojans. There are times I wished I had another panel on the roof and more batteries.
