10W(Watts) 12V(Volts) Monocrystalline 10BB Solar Panel High-Efficiency PV Module Power for Boat RV Gate Opener Fences

This panel keeps the deep cycle battery that powers my boat lift motor well charged. My only complaint (and it's minor) is that it did not come with any mounting hardware or any electrical connections. They leave that last detail up to the owner. I attached mine to a piece of metal conduit on the pier with u-bolts. It seems to be secure. Be careful when drilling new holes, there is little room behind the mounting flange. Time will tell how well this holds up to the weather but so far it's working.. May 2020, I'm on the second summer with this installation and it still works great. Adding a charge controller next week to keep the battery from over charging.

i have bought 2 of these, at separate times. I bought the first one to charge a 6ah 12v battery in my shed to power some 12v fans on a temperature circuit to keep it ventilated in the heat. I just bought a 2nd one as a upgrade to add extra power for some more fans, and fitted to the solar controller i bought these keep both batteries fully charged even when fans are running all day, even on days where the weather isn't ideal. My only gripe is how hard to mount they are. The screw holes are to hard to get to, so i ended up bounding them to the shed roof. I guess they are made to fit a rack, and i was unable to find one that worked. Well worth the money, but must be fitted with controller because peak unloaded power is 22v, (normal for a solar panel incase you didn't know) so it would kill a 12 volt battery without one.

I bought two NewPowa panels for a solar-powered automatic door on my chicken coop. The first one was a polycrystalline model (same wattage, slightly larger); that one was harder to install, since the holes on the panel frame weren't quite big enough and had to be tapped out for the mounting screws which came with the (separately purchased) mounting brackets. This one, the monocrystalline model, had holes which didn't require any extra drilling, but I did still have to buy the mounting hardware separately. And it's a bit tricky to install; holding the nut inside the frame while arranging the bracket and bolt would be easier with a third hand, and there's not a lot of room. But it's doable. The panel itself seems quite sturdy, and so far is putting out reliable power. You can get the mounting brackets from Amazon: https://www.amazon.com/gp/product/B0819MJ33Q I'm using the two panels with this charge controller and a 12V lead-acid battery: https://www.amazon.com/SolarSynthesis-Controller-Waterproof-Lead-Acid-Discharge/dp/B07FCS2P4B

I wish the manufacturer included mounting hardware but the actual solar panel is excellent. It delivers the rated wattage and works nicely even under cloudy conditions to keep my DIY 18650 based 12v Li-Ion Battery pack topped off on a daily basis. I am running Aquarium pump 24hrs a day using this DIY solution. Oh by the way, I did use a Renogy Wanderer 10 Amp Solar charge controller to safeguard against overcharging of the Li-Ion battery pack on very bright sunny days. Having said that, Just like other reviewers who has commented, I too had some difficulty in mounting this on a roof. I had to improvise and got some additional mounting hardware from local store and drilled additional holes to mount this on roof. If you are handy and do not mind finding your own mounting brackets then for the asking price the solar panel is surely worthy of the price. Rating the product with four stars!

This got delivered by FedEx in a soft envelope! Husband thought for sure the glass plate would have been broken. Not! It was perfect! Hooked this up to a system we have had with the same size solar panel that had stopped working very good (only charging 20%). In less than 3 hours this baby fully charged the battery!!! Fantastic!

Works great at maintaining a rarely used vehicle of mine. When it keeps it topped off on voltage, I get away with leaving the battery in the vehicle in cold Wisconsin winters, and it never dies out. Remember to have a charge controller, so as to not over charge the battery. Stop reading reviews and just get this done before winter. It will be your friend and take care of you.

Installed this on an overcast day and it was supplying 19 vdc, which is great since the brand I had before would only supply 12v if it was a sunny day, Of course you would need to add a charge controller to supply correct voltage when battery needed charging. Now my gate battery does not die when it rains for a few days! This has been in service for four months without issue. It does not come with a bracket, I used the bracket that I built for previous panel I replaced.

Pleased with quality and output in direct sun. However if you cast even a narrow shadow on any portion of panel it halts output, whether shadow is vertical or horizontal. Perhaps i need to experiment with similar products to know if this is normal. I've been using it for hobbies and charging 12v lead acid batteries with diode to prevent backfeed (instead of charge controller) which is fine only if monitored to prevent overcharging. It will maintain 0.6amp from 0 to about 20v in direct sun which is 8.4 watts at 14v while charging my lead acids and 10.8 watts @18v so it does output advertised wattage! But when a cloud drifts over sun the output drops to 1/3 or less.
