Hi,

The rating of bi-facial is the expected STC rating, just like monofacials.

So if a monofacial is rated 615w its bi-facial counterpart is also rated 615w.

Bi-facials then have a ‘potential’ power gain on the rating.

For example, I have 6 x JA 605w bifacial s, they are rated to give me the 605w each, but I can get extra power of up to 653w each from bi-facial gains.

Here is my experience, I mounted it on a roof (regular angled roof), my max expected power at STC before bi-facial gains should be 6 x 605w =3,630 W. Then I can potentially get higher due to potential gain.

I actually get up to 3897w with them, so 649.5w each for 605w rated. That means I constantly get the bi-facial gain while mounted on roof.

The main thing is that your roof should be refective (etc aluminium) and from a white colour to like a light shade of gray etc, those are the roof colours that’s can reflect sunlight on the back of the s. Black roofs might not work because black and darker colours absorb light and do not easily reflect.

See the attached picture, the first bar on the chart, notice the Pmax 3897w.

Thank you for taking out time to actually prove the benefits of bifacial s even when mounted on a rooftop, most people here have been against it without actually ing their claims.

They are very quick to discourage anyone from considering a Bifacial s even when there is no longer a price difference between Bifacial and Monofacial s.

Jumia Anniversary Deals has come and gone, but there are still some nice offers from one of the sellers on Jumia named Globalomerce. His offers sometimes looks unbelievable like the Oneplus 5 8GB/128GB Version for ₦87,500 I came across but doubted it until I confirmed from his Facebook page that it was a clearance sale ongoing, but before I could rush to place my order, it was sold out I felt sorry for myself for not grabbing this Once in a Lifetime opportunity of getting such a deal. Please if you were able to grab any of this offers, respond to this post.
