450W N-Type Bifacial Solar Panel - White Glass

I purchased 12 of these and have been incorporating them slowly into my system. The first two I installed started activating the MPPT controller before the sun peaked over the ridge line. I have 8 currently installed and was capturing energy even on fully cloudy days. The sensitivity of these guys are amazing. I can't wait to install the rest.

I have been using the solar panels for weeks, they are producing excellent output.The packing was good, with foam inserts and pallet to protect the fragile panels. My solar set up is complete and getting big power every day.Couldn't be happier!

Very nice solar set! Hooked it up to my golf cart, installed 12v deep cycle battery and some neon lights, and it works like a charm. never charged it with battery charger again! Set-up is so simple and intuitive that didn't even looked at the instructions.
Reliable product

I purchased 8 panels for my off grid 2,050 square foot building in Texas. I combined them with 2 - 48 Volt 100 AH batteries and two Callsun 5000 Watt MPPT inverters. The panels are providing their rated wattage and the system has been working very well. I also received a 30% refund on my federal tax return.

These panels are able to produce power as rated and seem to be very well constructed. They're mounted to rails on the roof of our skoolie and so far have been able to produce 2984 out of the rated 3300 watts. The limit is actually our mppt which reaches the 100amps charging the 24volt battery bank.

Would definitely recommend these.

I have limited roof space so it was important to me to get the most watts for the space I have to work with. These are mounted on my garage roof and south facing. I’m in the Pacific Northwest and these have been fantastic. On cloudy days I’m getting about 15-20% of rated power. On sunny days, I’m getting about 90% of rated power. I have them connected in parallel to a solar hybrid inverter and 2 200ah batteries connected in series.

I bought 10 Callsun 450 watt Bifacial panels this summer and very happy with their performance. I got a really good deal. They were very well packaged on a pallet for shipping and arrived early with no damage. I have since bought 10 more Callsun, and would buy again.

These things really put out a lot of the rated power all the time. Even at sunset, they are still making some power.

I installed this panel on my RV a few weeks ago, to augment two other solar panels, and have benefitted greatly from it over the past few weeks, as I have traveled the Southwest to visit the National Parks in Utah. I have a "smart" charge controller, so I can monitor the output of my three solar panels on my cell phone. I was surprised to see the panels produce some electricity even as we drove through heavy clouds and rain.

Because the panel is mounted flat on my RV, it doesn't produce as much solar power as it would if it were angled directly toward the sun's rays, but I'm well satisfied with it. I'm writing this review in October, and I'm sure the panel will produce a lot more power in June, which the sun is higher in the sky.

Bought 8 of the Callsun 450 Watt Monocrystalline Solar Panels for my houseboat. All the panels were in perfect condition. None of the packaging was damaged when it arrived at my house. No cracks in the panels. All connections were good. Installation was easy. Panels performed up to the specs. Panels have been on my houseboat for over an year and still working like they are brand new. Would definitely purchase Callsun products again in the future

I recently purchased six of the 450 watt Callsun solar panels and added them to my existing system. I installed them over two months ago and they have performed perfectly... On a sunny day they exceed the rated output by a couple of hundred watts! Needless to say I am very impressed and pleased with them. They actually outperform my Renogy panels. Also, they make an excellent covered area by the poolside. It's a win win!

The complete process was easy from start to finish. The ordering process was made extremely easy as you can buy package deals at great discounts. I bought 12 panels and run them in two different legs of 6 to one Sungoldpower controller/ inverter. Each set of six push on the average 250 VDC at around the 12 to 13 amps which balances perfectly with the 6KW Controller which has the two solar inputs. The panels are large, but still easy to handle and mount. I'm 6'2" 245 pounds. I built a free standing mount as you can see in the pictures because it is easier for snow removal and cleaning. The panels deliver the voltage and amperage as described. The controller has run well for me for the past year as I feed 10 circuits in my house and run the Two garages and a barn. I bought two Controllers because I had an older system and I eventually want to run 240 VAC in phase with the two to the house. I only have one transfer switch at this time which limits me from putting the 240 VAC into action. Over all I would say these are Great Solar Panels, Well worth the money and of great quality.

My neighbor and customer requested I upgrade their panels from old 300 Watt single face to something better. I told them about the Callsun 450 Watt Bifacial PERC Solar Panels. They were interested right away. Shipping was extremely efficient and quick. They arrived very well packaged. They were easy to install. The factory holes lined up perfectly. The panels have been in service for a year now and still function 100% output. They no longer use their backup generator and they always feel free to use any appliances in their cabin. They even bought a full sized refrigerator and an 18k BTU split heat pump / air-conditioning unit. No complaints. No issues. I am a solar power repair and installation technician. I love Callsun so much I purchased 6 additional panels to upgrade my own system. You will not be disappointed!

The product was professionally packed, preventing damage and delays resulting from the time to redeliver.The product has delivered superior results, even during times off overcast.The cost per panel was low, not compromising on the power, quality, and durability of each panel. The shipping was relatively low costing.My total cost for 48 panels was less tha $16k.There have been pluses throughtout my entire purchase. I find thesr panels to be the best in today's market.
