Review: Good deal on decent bifacial panels. - Pro: These are Bifacial so i first tried using a mirror under it to but i could only get up to 79w that way. Then i did some internet research and it said to try a white panel with a matte finish to have diffused light. I found the cardboard box the panel came it is sort of ideal so i spray painted the inside with a matte white and tried them again and got up to 92w- a big difference! so KEEP THE CARDBOARD BOX it comes in. It works as a good base when painted white and it is a perfect case to keep the panels in. That 92w is in Washington state in winter so the sun is very low in the sky going through a thicker part of the atmosphere. In summer when the sun is high I should be able to get over 100 with each panel. They are very light and easy to move around. CON: The Junction box is on the front of the panel which is unconventional and a little strange but easy to work with. If you are looking for the Maximum series fuse rating I contacted the seller and it is 20A
Review: Great economic solar panel - Nicely constructed solar panel that is somewhat flexible. I plan on using two of these on the roof of my crew cab 2500HD truck to power a solar generator I built. I do worry that the backs of the panels get hot so I may place a barrier between then and the roof of the truck. My solar controller says they are pushing watts so I am happy. Power output seems to be about what I would expect, and my battery (2 50AH Lithiums in parallel) fully charge up each day after 8 hours of 5AH breathing machine so i am happy.

## Features

- Bifacial Solar Panel: (it is old version, product size is:41.3"L x 22.2"W x 0.2"H, the size is different from 2x100W new version). Compared with traditional solar panel, this bifacial solar panel can generate electricity not only from the front side, but also from the back side, efficiency increased by at least 10%-20%. (Package does not come with the kickstands that the photos show).
- Lightweight & Easy to Install: It is only 0.2 inches in height and weighs only 4.4LB (2KG), the solar panel is easy to transport, install, hang and remove. The pre-drilled holes and PV solar connectors help you install easily and quickly.
- 9 Busbars Solar Cell, High Conversion Efficiency: 9BB & A Grade Monocrystalline silicon solar cell provides high conversion efficiency up to 23%. The narrower busbar space and more cells receiving surface bring lower cost and increase the output of the PV module. Compared with 5BB panel, the 9BB solar panel ensures lower risks of microcracks and longer service life.
- Waterproof & Dustproof: This solar panel is equipped with IP67-rated junction box to effectively block water splashes and dust from outside, making it perfect to be used outdoors. It is much more durable than traditional glass and aluminum model solar panels. 2 pieces bypass-diodes are built in the junction box.
- Excellent Quality: The solar panel is made of ETFE material, which has a higher light transmission and longer service life than ordinary materials. The back panel is made of TPT, which is good for heat dissipation, waterproof, high temperature resistant and easy to clean.

### ⭐⭐⭐⭐⭐ Great economic solar panel

### ⭐⭐⭐⭐ Works up to specs, but when not on sale it cost almost the same as 2 100w panels.
*by A***H on June 18, 2024*

Some of these panels sometimes arrive bent on the outer aluminum frame, I know these bend a little, but shipping damage can break or crack the solar cells near the aluminum edge. This company needs to package them better, often they get bent or damaged in transit. Only gripe. It works well up to specs rating. But i do not know if a bi-facial panel works any better as just the one sided panel ??? The price is good on sale....I think it puts out 120 watts in bificial sun? Not sure yet have to do a solar array test. I have these wired in pairs series, to make 24v. Make sure buy in pairs, 2 solar panels to make 24v. Less large wiring, more efficient in 24v over 12v. No reason to not get a 24v mppt charge control, even when you run 12,v batteries, you always run 24v solar to a mppt charge controller, it auto detects the proper charge voltage either 12v or 24v batteries, using 24v solar always, much cheaper to wire. No need to ever go 12v solar if you can avoid it. And or buy a 24v panel single, either way they make 24v. Good for efficiency. I do like the tiny bubble magnifiers built into one side of this panel. Seems to collect light rays at almost any angle. Not angle sensitive so that is a plus. Would work great on a flat roof like house or RV roof. Plus it weighs a lot less than an aluminum glass framed panel. Plus it's flexible to match contour of a RV roof up to a point, don't flex it too much. The other side bificial I will test output soon. I'll get back...... However needs spacers underneath to catch light on bottom of panel and for cooling panel. Plus one side of panel uses different colored solar light gathering diodes cells. Not sure how well bi-facial panels work ?!? Seems to be inconsistent different colored diode cells on one side. Probably okay. Works better on face side, more voltage and amp output. So who knows without testing. Front face is all the same quality. Has nice aluminum thin frame around perimeter. Nice looking and light weight. Looks durable enough. Has a good warranty. Time will tell.
