Bifacial FAQ

Frequently asked questions

What is a bifacial solar panel?

A module whose rear side is glass or a transparent backsheet instead of an opaque backsheet, so it converts light reflected onto its back face as well as the light on its front. The extra yield depends on the ground or roof under it and on mounting height; the datasheet states it as bifaciality — the rear-side efficiency as a share of the front.

Which bifacial solar panels are in stock?

5,723 pallets (106.4 MW) landed in California (City of Industry, Commerce, Compton, Ontario, Vernon), Georgia (Dublin), New Jersey (Jersey City, North Brunswick) and Texas (Baytown, Brookshire, San Antonio): TOPCon & PERC from Sunpro Power, CW Energy, Mission Solar, Waaree, and ZN Shine. Every line, with its power, frame and pallet, is listed on this page. Lots still in transit are listed separately with their ETA.

What bifaciality do these modules have?

As printed on each datasheet: Sunpro Power > 80 %; ZN Shine 70 ± 10 % or (80 ± 10) %; Waaree 80 ± 10 %; CW Energy 80 ± 5%. Datasheets that print no bifaciality figure are shown as "—" in the table.
