I've really liked these and they have worked well for a couple of buddies that have them, too.

They replaced my solar panels that got damaged in route to my mailing address. No complicated process or extra fees, they just did me the right.

They have a great product one panel came loose and fell between the shed and the house ripped the wire out had to fix it the panel was not cracked i had to get the right diode to replace the damage it took some time to find on the web fix it and it still working it been 3 years and proud to say it the best I've seen so far runs computers microwave little oven ect in my house it also run my plc and light in the shed I'm still looking to buy 8 more panel but money is tight my bill is lower and it helps thanks' Renogy.

A higher watt means more watts in your daily spendable battery bank forevermore! Shippers do need to keep in mind the weight as do people installing on rooftops why do I prefer yard-mounted systems if no shading is a real issue a solar pathfinder is awesome Go Solar !!! Bank with lithium if you can¡­

Had these up and running for about a month running 4 panels into an 80 amp solar charger with an 8-battery bank

I like these panels are would buy more

Work great! Replaced 2 (out of 3 in the small array) Renogy 270w, 24vt polycrystalline panels destroyed in a 75+mph line squall, when the whole anchored mount came out of the ground and went airborne. (Let me interject at this point . . . the original installer of this system I ultimately inherited, was unbelievably ignorant surrounding most all aspects of his installation. My advice? If you contract a complete system solar installer, seriously do your DD and if possible, get recommendations and inspect his/her completed projects. I have had to add myriad protections, calibrate all components to match factory engineering specs, and completely replace the ground mount array supports. I have decades of experience to match my low-voltage education and certifications/licensure(s), but most people having a system installed will hardly ever know what they're buying. The original owner found this guy on FB and just took for granted someone on FB would tell her the truth about his qualifications. He, of course, didn't! )

I bought 6 of the 320W panels 3 years ago for an off grid cabin. They were on sale! I am now retired living there full time. I was surprised how much power they produce when it is cloudy. One benefit on a cloudy day is the clouds diffuse light and the panels generate power long before or after they normally would but with reduced output. Better than none! Considering 12 more panels for my RV. I have 2 A/Cs there. They will be mounted flat which isn't optimum. 3 roof mounted panels face morning sun and 3 face evening sun. 2 EPEver 4215 40A MPPTs, one for each string. Recently upgraded battery - 16 Eve 280A in a 24V 8S2P configuration yielding ~ 15KW-hr of storage. I use a Giandel 4000 W inverter. Previous 5K battery required generator for overnight A/C. Now I don't. These panels power my cabin, my garage and tools, and my new electric yard tool center shed with a riding electric mower, 2 electric push mowers, various electric yard tools and a small air compressor. In Summer, they produce almost all of the power I require necessitating rare occasional generator usage. The computer and monitor are 250-300W which are the largest year round draw on average. I run an 8000 BTU A/C all night on battery alone. I also have a water cooler and 7L mini-fridge/ freezer that run all the time. Keep in mind, I can only charge the riding mower when I have enough sun. The charger draws ~1500W. Since it is only used once a week or so, several days can partially charge it.
