ECO-WORTHY Bifacial 195 Watt 12 Volt 12BB Solar Panel Monocrystalline Double-Sided Power Generation Rigid High-Efficiency PV Module Power Charger for RV,Sunsheds,Canopies,Farms,Home and Off-Grid

We had 10 year old solar panel technology which was still working at our full time off grid location, however so many new advancements like bifacial and bus bars made me think we could be more efficient. These truly exceeded my expectations. The only thing we changed in our system was the solar panels so measuring the performance was remarkably evident. We are cracking in double the watts when compared to the ones we removed. Even tho the previous solar panels were 10 years old, they had been functioning pretty much the same as when we initially posted them. We are ecstatic. Worth the investment. The build quality was superior, solid aluminum metal frames. The electrical components are securely mounted to the back side of the panel. Plug and play connections couldn't be easier. Literally we unplugged our old ones, drilled some new holes in the new frame to accommodate the already mounted z holders on the roof by placing a wood block between the frame and panel. Then we mounted the new framed panels on, plugging in the new connections. Immediately we could verify each panel was working on the Outback brand charge controller. Recommend these panels highly for anyone looking at electrical options.

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.

I love these panels, I’ve purchased them on 3 or 4 separate occasions. Seem to be a quality panel at an affordable price. Only thing I would change is a little more secure packaging. Delivery services don’t seem to be as careful with them as they should be.

This was my first diy attempt at solar energy. It took me about a year to get all the kinks worked out. For the money, I believe that these panels are very good. Not sure about the double sided use for my application, but I think it definitely increases the possible total watts when set up with adequate reflection to the backside. I currently have a total of 780 watts of solar and a storage capacity of approximately 5000 watts and plan on expanding it as quickly as I can afford to by adding two more of these panels.

Purchased these to set up a 2nd array to power my solar generators. I am still waiting to mount on my roof while I await some parts for the setup but have them on a rack on the ground currently until I complete the install. Even while not in an optimal location, they are doing a solid job generating power for my generator and inch for inch generate more power then the panels I have had installed on the roof for 4 years. Very impressed. Worth noting, you want them on a rack vs. flush on a roof because they generate power from both sides of the panel and will gain some power from surface reflection. Update: After using these for a couple months they are amazing! Generating more power than my existing 400 watt array.

I'm very disappointed with these solar panels I bought two of them and I'm very lucky to get 100 watts out of either one of them I also bought the 120 panels and they're non producers too I'm guessing I got what I paid for

Why did you pick this product vs others?: Great price on solar panels that work well

Works ok. Highest I’m getting is 106w in full Hawai’i sunlight.
