20W High-Efficiency Monocrystalline Solar Panel for Off Grid System, Charge 12V Battery of RV, Boat, Camper, Trailer, Gate Opener

The media could not be loaded. The Alrska 200 watt Solar Panel, and I must say, I'm impressed with its performance. This high-efficiency black PV module is an excellent addition to my 12/24 Volt system, and it is a very reliable source of power, I use it to charge my power stations.What I appreciate most about this solar panel is its efficiency. It consistently delivers the promised 200 watts of power, allowing me to charge my devices, run appliances, and maintain the necessary power.The mono design ensures optimal energy conversion, even in less-than-ideal lighting conditions.Installation was a breeze thanks to the clear instructions, and the build quality isgreat. It feels durable and I can bring it with me if we go camping.Overall, reliable and efficient source of clean energy, making it a must-have for anyone that has RV, boat, cabin, or off-grid system.

This is a two year latter review. I hope the seller sees this. And if they help me out I will change from a 1 star to 5 if they stand behind this product. It's 1 plus years later sence this array was put into use. The pannel are Excellently made, rigid and take all weather thown at them well. Being in utah Salt lake area... Winters are cold and snowy and summer in late july and august reach over 100 degrees. When first installed. The out put on 5 200 watts units in series was amazing. Pannels never put out what they are fully rated at. But in good sun... I had 5 rated at 200w ran in series. And when in optimal sun conditions.. I consistently pulled 850 to at times 940 watts. AMAZING. Worst case senerio late in the year when sun is not fully optimal or over head, it has still held at 450 to 550 whats. I am glad i did not rate them at that time. Now at 1 year plus out I have had 2 fail. Another failing. Voltage is still good. But amps , have dropped to 1.5 and 1.9 on 2 pannels. The 3rd pannel is down to 4.6 This has crippled my whole 1000 watt array in Series. I had to pull the two dead pannels out as it crippled it to 210 watts in best sun condition. I have left the other amp failing panel in but it is crippling the pannels in series, and I will soon have to pull it as AMPs output is failing on this pannel. So, at 1 plus years, I have had, give or take, 50 percent failure as this is a five pannel array charging 3 Ecoflow Delta Pros. One main battery and 2 extra batterys plroducing 10 plus killawat storage. If the seller will make this right. I will give a 5 star rating as the seller will stand behind thier product. And that is what really counts in the end. These ridged pannels should be good for 10 years or more if taken care of. I clean them regularly. It is the materials that have failed. There is no visable damage to the pannels as I have them well protected, and cleaned as needed. No scratches, hot spots, blistering or visual damage. They still look brand new. I would highly recommend these units for there output, build quality and cost to Wats ... but That is to many failures in my array for 1 year plus array. Please reach out to me seller to help if you would. It is not your fault for failure. But sellers that stand behind thier product gives one confidence to stay with them. Other wise you need to look to diffrent pannels.I hope this review was helpful. And di nt blame seller for product failure. Mabe I just had bad luck. But I will never know untill they are replaced. And if the seller does not stand behind thier product, I will have to rebuild with a more reputable pannel.Price to watt output is UNBEATABLE!!!. That is why I bought them. But now 1 year plus, Mass failure on AMPs out put. Voltage has remained the excellent same. But voltage WITH OUT consistent AMPs means.. LOW, VERY LOW WATTS.You do not start saving money untill your investment is payed off. Then only do you start saving and making money on Solor power and you Battery wall back up. Starting all over with new matched pannels will set me far back in finally Making money on my solor array and Battery back up Wall.I hope seller reachs out as like i siad, this may have just been a flek of bad pannels.

Hello all, first I’m going to tell you that I ordered one panel from this company to check them out first. I have never heard of them but I thought I’d give them a shot. I’m completely blown away by the results of my testing of this 200 watt solar panel. I was expecting to get about 150, maybe, if I was lucky, 170 watts from this panel. To my surprise, 183 watts straight out of the box, yes I do realize that it will vary for everyone depending on the conditions and maybe I got lucky but it seems to be a pretty consistent number so I just ordered another one and it arrived on 11/26/22. I will test the two together and get back to you all. So far, I’m super impressed.12/3/2022. I just ordered two more for a total of four now. Enough said, I like these panels.12/24/2022 This is a phenomenal update, I have never had a solar panel that will produce exactly what it is advertised for, see the photos I just posted. I have four 200 watt Alrska solar panels, it is 31 degrees at this moment and I’m pulling 813 watts with the four 200 watt panels I don’t expect you to take my word on this, you don’t know me, therefore I have posted 3 pictures as proof. The time is 11:50 a.m. as I type this and I am completely blown away by these panels. All I can say is I will buy four more in the very near future. Alrska panels have delivered for me, Alrska please make higher watt solar panels in the very near future. P.S. I’m completely blown away by these panels.07/30/2023. Just ordered and received two more for a total of six, still very impressed.

The panel are decent but it seems like they are really 100 W panels,

Been working well for awhile now

I purchased 3 panels for a total of 600 watts. I have a small setup in the garage to power misc items.The panels started off okay. I was getting 85% to 90% of the advertised power. After a year of use, one panel has died and the other two have significantly dropped power. The voltage has remained steady but the amperage has dropped. From 600 rated watts, I am now getting 90 to 100 watts after a year of use. I live in S. CA and the weather is primarily sunny.What initially was a value purchase will turn out to be more expensive. I do not recommend this product.

I had another 100 watt panel but it was less elongated like these (yes, I purchased 3 of these), however powerwise I get about the same - the most about 89+ Watts on a sunny day... The fact that they are long and narrow, as measured, make them so far the best fit across my camper and it feels they are easier to handle and put out and take off and angle towards the sun (I set them on top of the camper through the sunroof when and as I need to charge my battery "generators" - they have a built in solar power regulator - I got that provide 12VDC, 5VDC and 110VAC inside...One panel per generator)I may build a permanent mount but still to figure out best way to run the cables from the camper roof to the inside.
