Good performance and easy installation
I am very happy with this product. I installed it on my 35 foot fishing boat with two banks of batteries. I previously purchased a 20 watt solar charger from the same company through Amazon. I live in a temperate rain forest in southeast Alaska. The 20 watt unit provided some charging, even on cloudy or rainy days, but was not enough to maintain a full charge. I added the 50 watt solar charger and it now maintains a full charge, even on cloudy and rainy days. (about 12.8 volts) On sunny days it maintains a voltage of 13+ volts. Both chargers were easy to install and work great.

Works exactly as expected
After reviewing several panels and determining that I needed one with the capability of being weather resistant, I decided to purchase the 20W SOLPERK Solar Panel Kit 20W 12V, Solar Battery Trickle Charger Maintainer.Initially, I read various concerns about overcharging the battery were stated on other SOLPERK reviews, as well as some hardware issues, but as this one had no reviews at the time, I thought I would take the chance to use this panel to charge a 12V battery that I use to provide light to my stand-alone shed.Installation was straightforward and aside from finding a way to thread the wire from the roof of my shed to the battery, there is nothing complicated about the installation. (I did create a bracket to prevent damaging the roof, and would recommend that approach to prevent inducing leaks on a shingled roof.)After set-up, I didn’t see a green light (indicating complete charge) on the battery indicator, but since I hadn’t charged the battery in a while, I thought I would give it time. I did monitor the output of the solar cell (roughly 14V depending on sun exposure) and noted that with no load, my battery was just about 12 volts. After a day, the voltage on the battery popped up to about 12.4V, but I still had a red light on the battery charge indicator. By day 3, the battery light was green and the battery was at full capacity.Testing a week later, I drained the battery a bit by leaving some lights on for about 1 hr (12 V LEDS). The battery charge light was red for a period of time and then went green again. The battery had maintained full charge.At this point, I’ve had the panel connected to the battery for about 2 weeks and all seems well. Should I see the battery overcharge or diminish in capacity, I will update my review, but until that time comes, everything seems to be working well.

Great system, but watchout
I bought this controller after getting tired of connecting a charger/maintainer to my generator battery every three weeks or so.I installed this panel on my house roof and, on a cloudy day, it still delivers 22.54 V and 1.5 A at the charger-controller.However, there is a BIG gotcha. The connector from panel to controller is reversed (see photo).I didn’t notice this at first, didn’t even see it, until after several exchanges with support I decided to look closely. By this time I didn’t want to get back on my roof to desolder and reverse the wires at the panel, so I cut and reversed the wires at the controller. So, if you’re considering this item, beware.

Working great on my gate opener
I have a mighty mule fm 500 gate opener. I was having frequent problems with dead batteries with the dinky 10 watt mighty mule solar panel. I haven’t had a single case of dead batteries since getting this solar panel 2 months ago. I bypassed the mighty mule charge controller and wired the solar panel directly to the batteries using the included controller. And-I now have 3 batteries wired together in a separate box. This solar cell keeps them charged with no problems. I would recommend.

Good panel
Very good panel. Installed on the roof of my trailer and it’s been great.

Works as intended.
Works as intended. Keeps both batteries charged on my pontoon boat. I used a charging diode to keep them separated.

Easy Installation, Appears Well Built, but Be Careful of Manual
Just installed this week, so unsure the longevity, but the panel was putting out 23 volts on a cloudy day, so that’s a good sign. We bought two to power GTO automated gates on our farm. The original panels were 20 years old and needed replacement. We bought 30W panels, but found the batteries (deep cycle marine batteries) were not recharging sufficiently. We are now trying these 50s.The product was well packed, and the hardware and fittings all look well made. The only issue I found was in the instructions, where on the right hand page, the brackets are installed on the panel upside down. On the left page, it correctly shows the brackets with the hing at the top. On the right page, the hinge would be on the bottom. This assumes the wires from the panel output should face downwards coming out of the housing. Otherwise they bend backwards hanging down.A minor issue, but it did make me have to install the first set of brackets twice. Once corrected, installation was easy. The power control box handy and informative. Do read directions regarding the order that the connections are made. Note, I used the power controller with the panel, as opposed to hooking the panel directly to the gate’s power controller, as I was unsure the wattage the gate controller could manager.

Bad product
I opened the package to install, and it was shattered and there is no return or refund. I do not recommend!

I must say that this solar charger is exceptional. Iâve used it seasonally for the past few years. It charges my heavy duty deep cell marine battery weekly without issue. The battery is usually at 25% by end of the weekend as I use it for my trolling motor. I hook it up on Sunday and by the time I return on Thursday itâs fully charged.

I had ordered a different brand from a different supplier where the controller didn’t work. So I odered this one. I could tell immediatley it was better quality in not only the solar panel, but the controller was metal instead of plastic, and has an extra connection for a light. Although I found out of 2 I ordered, the solar panel LED indicator light doesn’t seem to work. However it does chaarge, and operate correctly otherwise.

Les fils étaient assez longs pour bien rejoindre ma batterie et la pose était simple. Ãa serait vraiment un atout d’avoir des instructions en français. Je donne 4 étoiles parce je ne suis pas en mesure de savoir si ça recharge bien. Avant je devais charger ma batterie au moins une fois par semaine.
