Hypothetical: Let’s say you live in a hot, humid climate like, oh, I don’t know, the Texas Gulf Coast. You have all the sunshine you could possibly want, and in summer you have a good 14 hours of it per day. The only problem is that it’s astonishingly hot and humid all night long and you want to us…

Est 6ah x 12hours = 72ah So battery pack of 200ah would work if you recharged them everyday. 300w solar = about 80+ah day So 200ah+ batteries and 300w solar is my hypothetical answer. :sunglasses: These numbers are rough. If I’m way off, someone please correct me.

Thanks for the speedy reply :hearts:. I will continue to do more research on this

I’m gonna keep posted because I have the same question being here in Miami. We’re just trying to escape the hot nights. If I come across any info I’ll share it with you.

Let us know what you find out. Im sure many others have the same question as well. Thanks :slight_smile:

I have 160w panels and a 100ah battery. I do not run an ac though. I have plenty of battery to run my fridge and fan for cooling on those hot nights. The key is to open a couple windows with the fan and get good air flow. (Make sure you have fly wire to keep those bugs out)

I’m no math whiz but in my research on this topic, I was told by multiple sources (including Bob wells’ book) that solar to run AC it’s completely. This is a very popular topic over at skoolie. net forums. I don’t want to be rude but I’m pretty sure your math is way off or most of us would have so…

This a why I just go for the good air flow and a small 12v fan :+1::ok_hand:

Exactly! I actually just use a couple battery powered fans. They’re super cheap. Kind of offsets there price of batteries. My 8" fan takes 8 D cells and my 3" fan only takes 2. One set of batteries lasts most of a spring/summer, but then again I can use them sparingly because I travel with the sea…

Hey! I dont know how much solar you would need but since its for ventilaton, maybe this is an option to consider. Ive bought one of these solar ventilation fans and they seem to be pretty good. I havent installed it yet so I dont know for sure. According to the specs it can run for 8 hours after onl…

Yo @bizness . So I know this is a UK company but they are great with solar equipment and they also have a calculator on their website! https://www.bimblesolar.com/
