2 Pcs 100 Watt 12 Volt Monocrystalline Solar Panels Kit, with 30A 12V/24V PWM Charge Controller for Outdoor RV Boat Trailer Camper Marine Off-Grid Home (200 Watt with Accessories)

This panel comes with a variety of accessories enough to connect it to almost anything. I don't know what the longevity is because I've only added a short while but I was so impressed that I ordered another. If the lifespan is as good as the great deal on the panel and accessories I will be extremely impressed and suggest anyone looking for a panel of this size and wattage make this purchase. It's the best deal I could find and considerably better than others.

I use this product on my troll motor deep cycle battery. This troll motor is on a pontoon so it uses alot of battery power to move my pontoon around while fishing Hooked up my SunSul charger to the battery which keeps it fully charged. No more carrying the heavy battery to the house to charge. So far this has been a great purchase.

I have used this so far to trickle charge my Riding Mower and my Town & Country minivan, and seems to work great. Easy to move between things needing charged. Good quality, well made. Works as described. Might even buy another one later on. Just don't touch the controller when it is charging, as it gets pretty hot (normal). I have mine mounted to the back of the charging panel, so it is out of the way, and somewhat protected from the elements. Really like this.

I wanted to power four small fans to cool a 1/4 hp motor for a pond aerator. The problem was the solar panel simply could not recharge the 12v battery being used to also run the fans at night. I could probably switch to a rechargeable 6v battery and have a better chance of success. The small voltage regulator included with the purchase did seem to work OK. Yes, I realize the 12v battery was overkill, but I already owned it.Update:Originally, I bought a 20 watt solar panel. But the solar panel was not large enough for 24 hour operation. I purchased this 50 watt panel hoping it would do the trick. I checked the power regulator this evening and it was showing 12.1 volts for the battery. The instructions were straight forward and I did not do anything except power up the power regulator and check the display at the beginning and 24 hrs. later. I gave this review 5 stars because I feel confident that this solar panel will continue to work exactly as described.

So my mower doesn't seem to ever put out enough juice to keep the battery recharged, so about every 4th mowing session I find myself having to recharge the battery so it will start. This happens when the batteries are about a year old. Rather than forking out cash for a new battery every year and sending the old one back (to hopefully get recycled) I decided to add a solar charger that I can just plug my mower in when I park it in the shed. Installation was easy except for climbing up on the shed roof and It seems to charge the battery nice and keep it maintained. The panel was putting out a solid 24vdc when there was sun on it and the charger will regulate it down to the 12v for the battery.I did have an issue with one of the connectors not working. I reached out to the company inquiring about it and had a response the same day. They also did not hesitate to correct the issue and I had a replacement part in my hands in two days. EXCLELLENT customer service!

This worked very well for me. Setup was a breeze and if you place it in a good position to the sun, really works well. The only thing that I would recommend is that you invest in a good MPPT charge controller. The one in the kit works but instructions on how to read it are like reading Chinese and an MPPT charge controller is a better investment in your solar system.

I own two, one on my gate openers and this new one on a 12v DC solar light (we’re waiting for the light fixture head) One keeps a 680cca deep cycle battery charged, the new one will maintain (2) 9ah sealed batteries in parallel, and run a 12w 12v lamp shining all night long through a 12v DC photocell. My design in a NEMA3R raintight box. I forgot, my deer blind has one as well so I own 3, if you’re looking I recommend this, it has every wire and connector you need to hook it to your battery, meant for light output loads, i’m at 1 amp connected load, ohms law.

Somewhat surprised after opening box, for the price $$, how decent made & strong everything seamed to be !!???...... it's going on 3 weeks after I installed on my automatic gate opener. So far, no issues!!We'll see how she stands up to the test of time & the elements !!??..... right now, I'll give her a 8.5/9 out of 10 !!
