I pop riveted my panel to Renogy Z brackets and secured them to a 16X20 piece of angled plywood on the side of my snowplow shed The controller is fastened to an interior ceiling beam, and since it seems to be regulating the battery charge well, I am content to let it do its job without interference.
Like all of these products, be sure to keep your battery leads separated to prevent a short circuit. I rely on my plow to be ready when I need it, and a well charged battery goes a long way to make that happen. This system works well for me.

I got the panel, put as meter on it, got 19.87 volts. Controller connected, yellow light came on (no explanation in the minimal paper work what that meant) Output of the controller was only 4.3 volts! Connected to a battery to charge, light went out. Multiple emails sent to company (they have no phone!!!) went unanswered to after five days. Item returned to Amazon.
Amazon refunded my money the day UPS got the package which is excellent, though the money was put in an Amazon ‘gift card’ and not refunded to my credit card.
Edit: 12/7/2019 – The company reached out to me after the return was completed. They sincerely wanted to make things right. They sent (at no charge) a 20 watt panel/controller kit and asked if I’d re-review. I agreed. The kit arrived yesterday. I set it up temporarily, being extra careful to follow the directions. They are not written by an American and therefore, loose something in translation unfortunately.
The battery I used was a little low, 12.6V. I attached the controller to the battery FIRST and then the panel to the controller per the instructions. I rechecked the voltage at the battery and got 12.73V, which means it is charging. The was at 11:30AM with a winter sun (low on the horizon, panel vertical and not optimally positioned). So it works. I’d like to see the voltage rise further and will recheck tomorrow and the next day. Ideally, it will be in the 13V range indicating a full battery on a float charge. I will also check for a precipitous drop in battery voltage (the blocking diodes should prevent this) after cloudy days.
To use to charge a item like my tractor, it seems I have to disconnect the panel from the controller and then disconnect the tractor from the controller. Not particularly convenient. I would think you could leave it connected to the controller all the time being careful (read being responsible) not to short the output.
I suspect my problem with the first panel kit was a bad controller as only one LED lit and it was a faint yellow. All LEDs light now as expected. I have changed my rating from one star to four. If we hit 13V after a day of sun and no drop in voltage after a cloudy day, I’ll bump it up another star!
Edit2: 12/18/2019 Suner was disappointed I could not make a better review and they (Mason) was committed to doing right. Seems the controller I got was bad and the new one, worked as expected. The paperwork with the panel is not clear, a problem in technical writing from China to the US. Also, an email sent is responded to most likely while you are in bed at night, so it can be a drawn out process to resolve issues. But I can assure you, they will take care of you. Patience. My battery now has a full charge (13.7 volts float) in mediocre sun.
Here are the key concepts. The battery must be somewhat charged, 11.5 volts or better (less is essentially a dead battery). You must connect the battery first. Doing so, the controller ‘figures out’ the battery voltage (12 or 24). After a few seconds (two lights will come on), the lights change and you can connect the panel. Then after a few seconds, all three lights will come on. You are in business! If you disconnect the battery (like I do, it is maintaining a tractor) you must follow the procedure. Controller disconnected from EVERYTHING. Connect the battery, wait for two lights, , connect the panel, all three will light. Suner earned the five stars!

I plugged this in on Jul 1–90 degrees, barely any clouds at all. It yielded .81 A x 20 V = 16.2 Watts.*
I never expected an affordable solar panel on Amazon to have output equal to 100% of the description, so to be clear I’m not complaining, I’m thrilled with this panel. Thus, the 5 stars.
This takes 5 seconds to set up and is basically idiot-proof. If you want to mess with the light output then make it 120 (and it’s not idiot proof).
I use this for car camping (I wouldn’t call it glamping, but others might disagree). I have a heavy canvas tent and this is light enough to put on the roof or hang from a corner, if it’s not a windy day. I really needed 30 Watt to ensure net zero consumption, but those panels were too heavy.
If you need a longer cable just search for any SAE extension. This is what I bought so I can position the solar anywhere in camp, 20+ feet from my tent. https://www.amazon.com/gp/product/B07D54QN6B
Bear in mind that you will only get a few hours of maximum solar, you have clouds and haze (and rain!) and if you’re not moving the panel as the sun moves, you have angular issues.
I figure 1/4 of the time it’s at full capacity or 100%, 1/4 at 75%, 1/4 at 50%, and 1/4 at 25%. (This would be lower in winter, but I don’t camp then.)
Or on average just use 62.5% of the solar panel’s output when trying to figure out if you can cover your uses.
For this solar panel that’s 121.5 Watt-Hours on a 12 hour summer day by my calculations.
[I use my battery to run a fan, so on cloudy/rainy days I don’t get as much solar but I also don’t run the fan as much. You may have similar needs. If not, be sure to allow for cloudy days!]
[EDIT: I just realized I extended the panel’s cable by 25′. That could be a reason for loss of efficiency. The 5 Watt panel I measured below is much shorter.]
* This 5 Watt trickle charger (that doesn’t require a controller) was outputting 5 Watts (.25 amp X 20 V) alongside the Suner. 5 Watts is in fact what it lists, so haze or clouds can’t be the excuse for the Suner.
[Again, I like the Suner and recommend it.]

Bough this for maintaining the battery on my motorcycle the olace where i park it theres no electrical plugs i decided to buy this particular model to use in the futere for more than that too. It does work and i actually tried charging diferent things and it worked out of the box. It charges car batteries, cellphone batteries with the right atachment, a light that atach to a cigarette lighter. I tried all i could find and it worked i even tried a tire inflator but that was its limit i tried all of it with out being attached to a battery just direct sunlight. Over all good panel for what i needed and costumer service is excelent if you got any questions or problems they’ll go out of their way to fix the issue as fast and easy as possible
