   These panels are great so far. Im new to solar and ive been trying random panels so far I feel like I’ve gotten the most out of this brand. The 200 watt one are great. I’d recommend them over the 100 watts.

   I have a solar inverter system on my work truck so I can have electrical power on the truck. I recently upgraded the charge controller and the solar panels. My original charge controller was a Tracer 1215BN and I upgraded to a Victron 75/10. My original panel setup was four 30 watt Renogy panels, mainly because it’s what fit on the top of the truck boxes. So not long after I got the new charge controller setup I found these panels which also would fit on the top of my boxes. The area is small, 16 3/4″ x 96″. The biggest problem was the width because it’s narrow. These panels were only 1″ wider than the top so not much is going to hang over. The new panels took longer to be delivered than tugapower.net said initially. They said a Friday delivery when I placed the order and Sunday after I hit the buy button. After they were shipped the date they said they would come they were delivered. They came out of CA and I’m at the other side of the country so 5 days travel. The boxes were only slightly beat up. A couple of tears made it through the cardboard but in the end no damage, not dents or scratches and obviously the glass panel survived. The next day I swapped them out the Renogy’s and fired the new panels up. It was the end of the day about 4pm and it’s winter so not much sun at that point. I think they pushed 36 watts from both panels combined. But the battery wasn’t depleted so not much for them to do anyway. The next day was sunny so I tested them. Turned on the inverter about 9am and put a small light on it and it went up to 40 watts. Then I put my Milwaukee battery charger on it and it went up to about 70 watts. Still pretty early in the winter morning. By 9:30 I had beaten what my old Renogy panels did just the other day when it was full sun at 2pm, 75 watts with an 83 watt peak. I was testing them and had a 60 watt bulb as a load. As the sun continued to rise in the sky I hit the 100 watt milestone at 10am. My old Renogy panels maxed out at 7.2 amps into the battery at high noon in the summer. And now at 10am in the winter with a low angled sun I had 7.8 amps going into the battery. I kept swapping out batteries and then had to go to my Makita charger as I charged all my Milwaukee batteries. I maxed out at 126 watts and 9.6 amps which is near the limit of my 10 amp charge controller. Since the way my panels are mounted, the back of the panels are hidden and the bifacial probably won’t come into play other than a small percentage sneaking by. But the reason I got these was their width so they would fit on my boxes. If the panels max out my charge controller I may get one that can handle the full output of the panels. I think the Victron 75/15 would be enough to handle the 200 watts that could come out of the panels. So on their first trial they beat my 120 watts worth of Renogy panels by a couple of amps. So I’m happy with that. As the sun gets higher into the sky as the warm weather comes on I’ll see if I have the need for a larger controller. Maybe I’ll get that 200 watts. More: It’s been 3 weeks since I put the system together. As the sun gets higher in the sky the panel output has been getting higher. Today was yet another record output from the panels Just before noon on a cloudy day where the sun was peeking in and out I saw an output of 189 watts from my two 100 watt panels (in series). The sun is still pretty low in the sky in March and it was nearly full rated output. Another 11 watts would bring it up to 200 watts. I’m sure when we get into the summer months I’ll be able to get the full output of the panels if I’m getting this close now. I did upgrade to the 75/15 Victron charge controller because the 75/10 was going to limit the power I could get from my panels. So far I’m pretty happy with the panel/controller combination purchase. And the bifacial aspect of the panels really doesn’t come into play because they are mounted flat on the boxes of my truck. Maybe just a bit squeaks by because of the transparency between the cells. But I can’t imagine much. More: Well apparently they can actually put out 100 watts per panel. March 17th I was able to get 199 watts out of 2 panels in series. The sun is still low in the sky and yet I was able to achieve rated output minus 1 watt. I’m impressed. I’m sure in the summer I might be able to reach that 200w+ mark.

   I have 2 of these panels for a shed to power a few things. These panels work well and look really cool with the all blacked out design. Good price as well.

   I received this panel today and got it set up hoping to upgrade my system from a 25w to this Bifacial 100w panel, once i looked over and didn’t see anything amiss I plugged it into my MPPT and put it out in the sun at a decent angle, and for the very briefest of moments saw it outputting about 80w mppt, however it immediately dropped to 53w (+/-3w) where it has stayed regardless of positioning (excepting a couple clouds passing over. I can only conclude there is a an issue with the panel as that is half the rated wattage in very good conditions.

   Short version is the panel looks fine, and without opening up the electronics connection on the box i can’t see any major problems, yet it is only producing half the power it should.

   I have the 200 watt version and I am well pleased so far, I have measured it at 197 watts on a nice cool day in Maine. It is large but it seems well built, only time will tell.

   This is the first solar panel that I’ve used that actually puts out the full wattage. Got 104W in full sun; awesome!
