Morn’ing Don,
Thanks for the graph. Those are pretty close to the members I had remembered. I was concerned that it may require more watts than I potentially gain. Though bringing from approximately-20 F to 32 F would effectively double available battery capacity, but not 100%. To try and calculate the wattage to elevate the temperatures that much, is far “above my pay grade”! :D I had resorted to the SWAG (scientific wild a$$ guess) formula. So, having already making the purchase, I’m down to experimenting.
Thanks again for all of the information and support!
Also....we have plans to set-up ours similarly. I don’t think that I can get the number of watts that you have ( insufficient room). But, I’ll keep measuring and researching available quality panels. Would love to do it with one panel....definitely “not” possible! I will be making the panel(s) tilt adjustable (like our 5er). I’m getting lazy.... adjusting “only” one reduces the work required!
