HD435/440XA-THE10 · Bifacial · Korea Expressway Corp. certified
Bifacial photovoltaic modules integrated with highway and railway noise barriers — turning sound-mitigation infrastructure into a power-generating asset.
435 – 440 W modules with bifacial architecture maximize yield on infrastructure sites.
KS certification, expressway quality criteria, fire resistance, and AGC anti-glare glass — engineered for road environments.
2 M / 4 M mounting frame options adapt to varying road-segment lengths and site conditions.
Both models share bifacial architecture, IP68 junction box, and anodized aluminum frame.

Expressway Criteria
Five core capabilities engineered for road environments, backed by verified certifications.
Certified under Article 91 of the Construction Technology Promotion Act — construction material inspections waived.
Fire-safety performance verified for both materials and structural members. Fire-resistance test passed.
Diffuse-reflection coating reduces external glare. Chungbuk Technopark measurements: 300–700 nm 3.85 % / 300–1,100 nm 4.78 %.
163 categories of highway construction materials tested — 9 categories passed (sound transmission loss, falling ball, pendulum impact, heat, accelerated weathering, Taber abrasion, allowable displacement ×2, load class).
440 W output and 21.16 % efficiency deliver stable energy yield on roadside sites.
Two frame options — 2 M and 4 M — to match road-segment length and site conditions.
Five outcomes that combine noise mitigation with energy revenue on a single infrastructure footprint.
Sound-transmission performance — 500 Hz 30 dB · 1,000 Hz 35.1 dB.
Generated PV power offsets common-area electricity costs.
Roadside integration reduces construction cost and ongoing barrier-maintenance expense.
Supports zero-energy-building strategy by combining demand reduction with renewable generation. Off-site renewable production counted toward building footprint.
Activates underutilized highway/railway sites and aging noise barriers. Building-perimeter applications also possible.
