At best 100% solar power being absorbed, it will kick out 8-9amps at 12v +-
Good luck. I know you so want to “make this work” but the practicality of it is of seriously diminishing returns.
I have a 325 watt panel (24V split cell) and I get 22amps out of it for at least 4 hours and it climbs and drops before and after. the thing about electric resistant elements any power put into them will have an effect, sure it might only be warm early but if you size it right, in my case a 300 watt 12V heater it will fully power it. in his case I would do a 200 watt element weather it is for the water or the space heater.
