Newpowa 9BB 6X360W 24V Solar Panel 2160Watt Monocrystalline Kit, High-Efficiency Mono Cells 24V Off-Grid Charge System for House Rooftop Residential Commercial House RV Marine Boat Shed Farm(360W6PCS)

I now have 10 of the 220W Newpowa panels. The first six I ordered worked so well that I got four more. Well made, no problems at all, and all of them worked exactly as specified. The packaging they come in is almost bullet proof as well. Despite some rough handling by the delivery service all of the panels were unscathed when they arrived. In actual use they work as specified. In excellent weather conditions they are putting out almost their full rated power, even up here in Wisconsin in less than ideal circumstances.

As a professional RV solar installerI like these panels a lot. I often recommend them to my customers.

I purchased the 240watt size. The major things to know. The frame is very study. I used the iPhone app for the ECHO Pro to measure output, the display response is very fast. On perfectly clear days in upper midwest it generates 190 watts perfectly aligned to the sun, 175-187 watts not perfectly aligned. When thin clouds pass by or the sun seems to be reduced by over 1/2 to 2/3, the output drops to 0-50 watts. Most times when clouds pass in front without direct sun, output goes to 0 (zero) watts output. PARTIAL SHADED common issues when only select cells are blocked with shade from any object I’ve noticed that if you block ONE cell (corner) the output drops to 120 watts. If you block TWO adjacent cells together in the LONGER direction, output drops to 60-80 watts. If you block two adjacent cells along the SHORT direction, the output drops to ZERO all the time. I'm not an expert but from online sources on Youtube, this is fairly common for partially shaded solar panels that are better, whereas those without by-pass diodes that are cheaper, any shading terminates all output. So just make sure none of the cells get covered at all. In full sun it works wonderfully and output is high. In full shade (when clouds pass over, output is zero). I think is fairly common to many better panels.

I hooked up two of these 250 watt panels in series to charge my Anker Solix C1000. The power station was at 50% when I hooked up the panels, and it only took about an hour and a half to charge the power station to 100%.I was getting 425 watts from the two panels on a mid February sunny day. This will more than suit my needs, and should charge my power station from 0-100% in 3-4 hours.This may not be the best value per watt in ratio to the price of the panels, but I am in need of something to recharge my power station in a short period of time while hunting off grid. These panels will do the trick!

just received this 4-panel set. Have only unpacked one so far. Was initially delayed in transit, but that is to be expected in this current environment. Delivered flat on a pallet. Delivery driver took the pallet off the truck and wheeled them right into my garage. Driver was very professional and helped me even though he had several other deliveries in his truck.Panels are very well packaged and no sign of external damage to the boxes. Now have every thing I need to really try these panels. I have finally received 50 feet of 8 and 10 Ga. wire with MC4 connectors and have two Bluetti EP 240 solar generators. Should charge fairly quickly at over 1000 watts of available power. Bought two Bluetti EP240's. Over a year old, very happy with these units. After 6 months in storage (initial full charge with wall outlet) these units are still fully charged. Need two (charge one while the other is running 12v frig and freezer (ICECO units) and LG portable AC unit. LG and ICECO units are top quality pieces of equipment. Placed both ICECO units on 36" SS shelving on wheels. Easy to work with and roll around when needed.

I was able to hit 182 Watts after re-alignment, that's about 86% of their rated output ....which is very good. I will be grabbing 2 more of these now that I have tested their performance. (For my MPP Solar 1012LV-MS project). Product came well packaged with no damage, highly recommended.People need to learn about how these work before they post bad reviews. All panels have a rated wattage output. Example: A 100w panel simply means it can have a 100w DC output under "Optimal" conditions.This includes unobstructed sunlight/proper angle alignment/power drop in cabling-etc. And the time these panels are in that perfect zone is maybe 5 hours a day. And remember, panels will pull only how much is needed. If your battery is charged and you're only using 150w factoring in inverter efficiency, don't expect panel to pull more wattage than is needed unless you are grid tied...it just doesn't work that way. I get 500-550w on any normal day with 3 of these 210w panels ,Off-Grid and very pleased with that performance. it recharges my 200AH Lifep0 battery from the night before and powers a basic home office at the same time. No issues.

i liked this so much that I bought another one! I have them connected in series and I'm getting 425W max. On a normal cycle, I get about 380 on the average. These 2 panels charge my ECOFLOW delta 2 and extra battery.
