Review: 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: Envoi rapide, emballage solide. Posé sitôt reçu. Il est très fin et, en effet, trés souple, parfait pour mon toit relevable sur Land Rover Defender. Les 100 w semblent bien là, en tous cas en plein soleil. Mon frigo a compression tourne a fond et la batterie 120 ampére reste chargée à 100 %! A voir sur la durée quelle sera sa fiabilité et sa longévité mais à ce prix, pour moi, c'esr parfait!

## 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.
