I want to charge 6-35AH. How many of which type panels will it take to keep them charged. I live on the Gulf Coast and have excellent sun, no shade,

This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max. But I find mine realistically charges about 5 amp hrs per hr. So 210ah/5amp is 42hrs of charge time. so you prob have 7-9 hrs in day of good charge, so 42/~8 is at minimal 4 panels... I live in midwest and have less sunlight per day. But I think 4 is about minimal. I work more with electrical consumption than I do with battery charging so someone else might have better charging math, but I am familiar with electrical systems. Hope this helps and sorry for all the math, just wanted to back my answer. Good luck. This is a rough guess but, 6x35ah is 210 total Ah, and if you have 100w panel/ 12v it's about ~8 amp max.

That's a hard question to answer,do you want to just keep the batterys topped off or is there going to be daily usage of the batteries also ? I would say with your constant sun 3-4 100watt panels would be enough. Mono or Poly panels don't matter with your amt. of sun. Go cheap ! They both will give you a life span of 25years give or take.Hope this helps.

You need to fully charged your Deep Cycle Battery. Connect your HQRP 30W Flexible Solar Panel and face it towards the sun where you have approx 8 to 10 hrs of sunlight daily . Also I have a Sunright 7 amp Solar Charge Controller for double protection of overcharging. I use it for my Battery Portable Solar Generator, and My RV's House Batteries (trickle charging)

I've found that a 100-120 watt solar panel will be able to recharge this system from empty to 80-90% full in a good sunny day's worth of sun. It takes the full day to do it and if it's cloudy or worse then expect 2-3 days depending on conditions. You will need to add a solar charge controller to help with the task and to protect the battery from being over charged.

You need a charge controller pretty much for any solar panel over 10 watts. I like the ones that have a digital voltage meter and built in float mode. Lots of choices for controllers in the $20 range Panel has held up well so far on my sailboat.

This is primarily a 12vdc device. You would need to set up batteries with an inverter to run your AC operated devices, and you will most likley need two or three panels to keep up with the demand. The batteries would need to be enough to run your heat lights all night I am guessing. Knowing (calculating) what your power demand is will be key to proper setup. That will tell you the number and capacity of batteries/inverter you will need and the charging demand you will need taking into account cloudy overcast skies (winter weather, etc..) when a solar panel is not as efficient.

I would think you would need at least 6-8 hours of daylight for it to get a good charge. It seems to do fine on cloudy or rainy days as long as it gets some sun for most of it. I live in Florida, so we don't generally have a ptoblem getting plenty of light for keeping it charged.

The charge control can handle up to 7A. Your 30 watt panel puts out ~1.68A at high noon. You should be fine with one charge controller charging two or more batteries and it would require more charge time. Just make sure you hook up your batteries correctly. Personally and for convenience I would much prefer to get two charge controller with two solar panels for the two batteries so that I could avoid having to move and or reconnect the batteries. A larger solar panel can would benefit you quite a bit if you need to drawn power from the battery each night. Hope you are using deep cycle batteries. The charge control can handle up to 7A.

I have 120w panel on my cabin roof but the sun doesn't hit it that hard....... I struggle to keep one charged. But the 100w is on the roof of my other little hunting cabin that is in the sun all day and it rocks the batteries no prob. Just all depends on the sun.

Yes with a charge controller and about 72 to 86 hours of constant sun light. For more than 60 Ah you should use 3 of these panels and always a charge controller.

Depends on your battery set up...doubt one panel will get the job done. Works great for my RV though.

I can't say exactly ... we have a lot of shade in our yard and they still charge. These lights are very durable and nice, although not super bright, but enough to line our walkway and driveway. I would Rec them for the brand and price!

Yes, that's true ~. 2x30watt panels = 60 watts going to your controller. Good luck & have fun capturing the Sun. :-)

Yes; in full sun one of these 15w panel will produce well over 800 milli amps close to 1 amp. 2 panels like these will double the charge rate and so on. My one panel easily maintains and keeps two 105 amp hour 12v deep cycle flooded batteries fully charge to over 12.6v month after month with about 6-8 hrs of full sun.

For one panel I use a 7 amp in line charge controller.The Sun Force 7 amp controller, which is available on Amazon for $14.01, has worked well for me.It also contains a diode to prevent the battery from discharging at night.The max output of the panel is about 3 amps.

There is a switch under the hood that allows you to turn ON the solar lamps. Take the top off, look for the red button and switch ON. I let mine charge in the sunlight for about 8 hours...and when it was dark outside, the lamps illuminated beautifully.

I haven't got the bill yet. I plan to install more solar colectors to offset the cost. I have a 20K system now and SCE will not let me install more until I use more electricity!!

The solar panel comes with a stake to put it in the ground or you can also attack it to the wall. It can be pivoted around. The lamp works very well&lt; at least 9-10 hrs. of light. and it lights up to 6 meters depending of how you place it. I live in Curacao, where we have a lot of sun, so no problems to charge the panel.
