There is not much that a 30w panel is good for, it's pretty small. What will you be doing with it ?
Is Mighty Max a gate opener ? if it's sold as being compatible with the opener, it's likely OKPowerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

See this thread. https://www.solarpaneltalk.com/forum...uestion-please
I'm using a 10w now and its not getting the job done all of the time, still in testing mode, I just want the battery to be fully charged by the end of the day. I figure more watts will not hurt and help with cloudy days.. but I did not stay at a Holiday Inn last night..
thanks for the reply, BTW I found the Mighty Max for a good price, then found a really bad review, then tried to find there web site, none to be found, so I got spooked and canceled the order..Comment

Looking back at the other thread you referenced, I'm still not clear, but will go out on a limb and take a guess.
LED's are usually rated in Milli-Amps when you look at their spec sheet. From the spec sheet, you can work out the milli-watts.. (Or I can if you link to the led's)
So I'll just guess that a 30w panel will perform better than the 10w panel.
I'll also throw in another approach to figuring this out.
You have led's that consume a total of > 2 < watts * 12 hours of night = 24watt hours consumed
You have a 10w solar panel that is only likely to produce 6 watts, for 4 hours (of good sun) and wile it "could" harvest 24 watt hours of power, batteries are lossy and need more watts to charge than they supplied. So a 30 or 50w panel would be more likely to work for your application of keeping the battery charged. You also need a charge controller to manage the charge and not overcharge the battery.
There is a Mighty Mule electric gate opener with a solar panel option and a couple sizes of panels - thats the source of my confusion.

Wish I could link to them but they were sold out for now, as I remember they were 22MW each, I change my plan so I'm only using three, so 66MW, I understand what you are saying which is why I think I should add a 30w panel for a total of 40w.
I am using a Regony Voyager controller, some days it will fully recharge and some not, so do you think 40w will do the trick ?
I am new to solar but do know a bit about wet cells, thats why my goal is to keep the battery at no less than 97% SOC at all times if possible..Comment

Just guessing, but I think 40W total is better than 10wPowerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

Ok I found another seller, this one says 1w.. I am running three so 3 x 12 hours is 36 watt hours. 40 watt panel, from what you said above at 60% of rating that would be 24 watts for four hours of good sun = 96 watts yes ? so I would have 96 watts to replace the 36 I used the night before, do I have this right ?
