FAQ

1. What is a bifacial solar panel and how does it increase power output?

A bifacial solar panel captures sunlight from both the front and back. By collecting reflected light from surfaces like white RV roofs, sand, or decks, it can increase total energy output by up to 30%.

2. Will the panel still work if part of it is shaded?

Yes. With TwinCell parallel circuitry, the panel operates as two independent sections. If one half is shaded by a vent or branch, the other half continues producing power.
