SUNGOLDPOWER 10pcs 450W Monocrystalline Solar Panel,Grade A Solar Cell, Waterproof IP67,High Efficiency PV Module for RV,Home,House,Boat,Farm,Off Grid and On Grid System (10 Pack of 450W),Black

I purchased 8 450w panels from Sungoldpower. As these panels are about 6 ft x 4 ft and weigh close to 50 lbs a piece, I’ll admit I was a little worried about how well they would survive shipping from California to Florida. They were shipped quickly and Customer Service was very responsive and helpful in increasing my order right before they shipped. They arrived in perfect condition! They are pretty sturdy! Within a few days I got them up to the roof using a rented drywall lift, hooked them up, grounded and anchored them, and now they are feeding my EcoFlow battery backup system. They are installed flat rather than being angled toward seasonal sun, but even on these Winter cloudy days the 8-panel array is putting out around 5 to 6 KwH. On sunny days I’m getting more than 10 KwH. I’m expecting to hit considerably higher numbers as the sun gets higher for longer in a few months. VERY happy with these! Would recommend Sungoldpower!

About a year ago I purchased 6 of these to try for a battery back up system and recently ordered 6 more to double my winter intake and run the house off battery more. After seeing the results, ultimately decided it was time to go off grid and placed a large order of 2- 8,000 watt split phase inverters, 5 wall mount battery banks and 12 more of these 450w panelsGreat packaging and shipping speed, very well built panels to hold up to Michigan's harsh seasons!Update 4/18/25:24 panels total rooftop and 62kwh worth of battery coupled with the 2-8,000w sungold inverters runs my 5 person household flawless for the last 2 months.

I told them how well they work in my system, however I have no room in my system to use them so remember it is just a logical review of if I could do it in my system of how well it would work. By the way North town aside they are working great and the repair area is back up and operating 100% with the replacement panels. The power is used for the lifts in their bays.

Great solar panels. They reflect close to the spec sheet supplied with the product. I also have a SunGold Inverter that is paired up with these panels. Very happy.

Super happy with these panels. Delivered on time and very good communication

I was surprised to find out there is no wiring with these panels, just a little pigtail. hope I don't spend a week trying to find the proper connector.

These panels are of good quality. I tested them up against a wall, on 80 degree day, humidity med. Bright sunny day at 12 noon on the east coast. They were maxing out around 630 total in series. But the panels were hot (to be expected) about 120 degrees. But what i have noticed was, my other different panels were about 135-140 degrees hotter. I think the half cut perc cells were doing what they were designed to do, keep cooler which was a plus. I bet they will do great in colder temps, maybe buy more. I would recommend these panels.

A lot of cloudy days since install. I did see 414w on one panel and 404 on the other. Very well packed. Delivery driver placed where I asked.Used the pallet to mount my frames side by side and tested.Great choice for my setup.I would buy again.
