## Features

- 2 Pieces 100W Bifacial Solar Panel: Update to latest version size: 36.61inch*23.62inch*0.20inch/930*600*5MM. 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Solar panel!
*by M***P on June 10, 2025*

Works as it should for a solar panel! Arrived on time and was well packed. Good documents and connectors. Solid (but fliexible).

### ⭐⭐⭐⭐⭐ worth the price!
*by D***L on May 27, 2025*

i got 90 watts out of one 100w panel with it just laying flat in the grass, very happy with quality and output!

### ⭐⭐⭐⭐ 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*

It works well up to specs rating. But i do not know if a bi-facial panel works any better as just a one sided panel ??? The price is good on sale....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.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.
