Hello everyone! So I am very new to all things solar and honestly not very knowledgable on electrical in general. I recently installed a Hoop House on my property and it need consistent power to operate the inflation fan along with some other things intermittently. I purchased a Jackery E1000 Plus with solar panels thinking this would work based on the numbers Jackery claims and what the numbers where to run the equipment for the hoop house. Here is a better breakdown of those for context.

Inflation Fan: 6 watts continuously
Vent Actuators: 55 Watts each x 2 = 110 watts but only when operating. Takes about 1min for those to fully open
Auto Side Curtain Motors: 60 watts each x 2 = 120 watts when operating, takes about 3 mins to fully open or close.

My Jackery is drained of power within 36hrs, despite running the solar panels. Right now the only thing operating is the inflation fan so ive determined to build a solar power system and return the Jackery as I don't feel it will live up to the needs I want nor allow me to grow my needs.

I have been looking at building the hand truck solar system and I want to figure out how many and what size solar panels to get. The hoop house will run 236 watts of power max intermittently throughout the normal day, at this time I don't know how many times a day those systems will operate as its based on temperature so those systems could kick on 20 times a day maybe more. We have not added lighting yet but plan to add some Led hanging lights along with potential to add a water pump down the road.

Since this will be a stand alone system and will be outdoors (inside the hoop house but that isn't heated or cooled) what issues should I expect and what should I add to my system to account for freezing temps and high temp days. We are in Kentucky so we don't get a lot of subzero days but we do get about 2 weeks worth give or take and we do see temps consistent in the mid to high 90's for weeks or month straight. So I don't know what systems solar has to protect the battery from those temps. I'd like to have this system built before winter hits some mid November would be great. If you're around the Lexington, KY area even better I am happy to pay for your time and knowledge to help me walk through a system setup.



 
I'll help.
fan, 6 watts for 24 hours= 144 Wh
vents, 110 watts for 1 min 20 times per day= 37 Wh
curtains, 120watts for 3 mins 20 times per day= 120 Wh

subtotal current demand = 301 Wh

Now, guessing at some numbers :
Inverter idle/overhead loss of 30 Watts for 24 hours==720 Wh
Add 15 % to demand for inverter efficiency loss = 45Wh

Total demand = 1066 Wh

Estimating 15% loss in charge controller, you'd need 1.25 kWh in a day from your solar panels.
