Dual column solar panel installation

How do bifacial solar panels work?

Bifacial panels take a different approach. These modules use transparent back sheets or glass-on-glass construction. This design allows light to reach solar cells from both directions. When sunlight reflects off the ground or nearby surfaces, the rear cells convert it into electricity. “The concept is simple: capture more sunlight from more angles.

Are dual-sided panels better than monofacial panels?

Industry-standard degradation rates average 0.7% per year for quality modules, similar to premium monofacial panels. The dual-sided construction may actually improve durability in some respects, as glass-glass designs resist potential-induced degradation (PID) and moisture ingress better than traditional backsheet constructions.

How do solar panels work?

Front-side absorption works exactly like conventional panels. The sun’s rays hit the front surface directly. Solar cells convert photons into electrical current. This accounts for the majority of power generation. Rear-side absorption captures reflected light. This is where the design shines. Light bounces off surfaces below and behind the array.

Who makes bifacial solar panels?

Global production capacity for bifacial modules expands dramatically. Major manufacturers including LONGi, JA Solar, Trina, and JinkoSolar commit to this technology. Economies of scale drive prices down continuously. China leads manufacturing capacity, but production expands globally.
