ECO-WORTHY Bifacial 195 Watt 12 Volt 12BB Solar Panel Monocrystalline Double-Sided Power Generation Rigid High-Efficiency PV Module Power Charger…
🌟【Bifacial Solar Panels】Bifacial solar panels are designed with a transparent back of 12BB solar cells, the back panel uses composite materials, the light transmittance up to 91.5%, the conversion rate of 23%, the power generation is 858Wh per day under ideal conditions, compared to traditional solar panels, energy surge up to 33%.In order to fully utilize the bifacial solar panels, it is recommended that they be used in conjunction with ECO-WORTHY’s Tracking Bracket/Tilt Mounting Bracket.
🛰️【Smaller Space,More Efficient】Size: 52.6 x 26.4 x 1.4inches（1335*670*35mm）, weight 20.48 Lbs. Compared to multiple 100W solar panels of the same wattage, it is smaller and more efficient in generating electricity.Diodes are pre-installed in junction box, with a pair of pre-attached 2.95ft Cable.Plug and play, friendly to novices.
❄️【Efficient power generation all year round】With the double-sided design of ECO-WORTHY’s solar panels, the back side is also available to provide power through reflected light, which helps heat the panels faster and speeds up snow removal in the winter. With the backside always available, our solar panels not only generate power during the light seasons of the year, but also in the winter months by reflecting off the snow surface, truly providing unstoppable solar energy for your off-grid lifestyle efficiently all year round.
🔝【Pioneering use of 12BB technology】 The product technology is ahead of the peer 5BB/9BB/10BB technology, 12BB technology improves the collection ability of the current generated by the wafer, providing higher power. It is also minimized by shadows and generates more power than ordinary 5BB/9BB/10BB solar cells.12BB solar cells, the best choice for your solar power system!
💪【Build to last】 The back plate is made of composite material and the metal aluminum frame is rust and corrosion resistant, which can withstand strong winds of 2400Pa and snow loads of 5400Pa. Both IP65 junction box and IP67 junction box have excellent waterproof function, so you can use it outdoors with confidence.
☎️【Long-term Warranty】As a professional solar system manufacturer that has been deeply engaged in the solar field for 17 years, we promise a 25-year ultra-long transferable power output warranty. Whenever you encounter any problems, ECO-WORTHY team will actively provide you with professional off-grid system solutions. ECO-WORTHY bifacial solar panels are a trusted, high-return and long-lasting investment for your energy needs.

Power output. These are reasonably priced, and beat the $1 a watt, especially if you catch the $30 coupon. They really boosted my Output. Excellent Quality. Arrived quickly.

Eco-Worthy Solar panels are very definitely our solar panels of choice. This is because;
1. They are most efficiently priced. 2. They have the highest output efficiency. 3. They are built the strongest. (They are built to withstand an RV going 70 mph with a headwind of 30 mph). 4. The 195 watt panels are very easy to handle and install by only one person, so our electrician students can very easily manage a DIY installation themselves at their homes. 5. We use 5 of the 195 watt panels in series, strictly utilizing the National Electric Code specifications, as all those in series add up to high Direct Current voltage of 130 volts DC in very cold weather with full peak sunlight (1 sun). We use the West-Southwest orientation (20 degree tilt) to maximize power production for the Summer July 15th through Sept 15th maximum seasonal temperature peaks. (This orientation drives a 12,000 btu 22.0 SEER 1 ton heat pump for a 225 square ft master bedroom) at or very near a 100% /24 hour runtime at 1 sun.)

I like these panels. Work as advertised and better than expected. I strongly recommend them. Will buy more in the future if they are available. If I opened a business selling solar panels, these would be in my product line up.

I found the ad to be misleading as the panels are actually 150watt panels and with the back capable of producing 30% of the front or max of 45watts the panels max output front and back together totals 195.

It is important to me that when making an Investment like this, every panel has a serial number and temperature coefficients either in a manual or on the panel. This has both.
These panels perform very well when all factors are taken into account. Those factors are how much w/m you are receiving, air temp, humidity and atmospheric interference that blocks the sunlight that gets to the panel. All weather center and almost all irradiation meters use the full light spectrum light brightness meter and calculate watts/meter.
I bought 4 of these panels, data logged their performance them over the past 2 days and based on my data, they are indeed 195 watt panels.
With 850 w/m reading, 50% humidity and 41c cell temp, I’m seeing between 150 to 155 watts. Considering the cells are rated at -0.5% per c over 25c and max watts at 25c is 165 watts in 850 w/m sunlight, 150-155 watts is well within specifications. This is while sitting on a rack at 15%, facing south in Florida. The only negative I see is they are only warrantied for 2 years vs 10 from others but at this price point, you can’t beat this if you can put them in a location to take advantage of the bi-facial feature.
Overall, I am very happy with these panels.

We have tried multiple brands and types of solar panels, both in the desert and the rain forest. We are super happy with these. Five power our house in the rain forest, with no problems even on multiple cloudy days. Double sided is useful if you have a reflective surface underneath (like a mirrror, tin, or white paint).
