How Polycarbonate Sheets Power Building-Integrated Solar Systems
Market Growth 2026:
- Global BIPV market: USD 28.3 billion (projected)
- China BIPV market: RMB 300+ billion
- Annual growth rate: 25–30%
- PC sheet demand for BIPV: 35% increase YoY
Why PC Sheets Matter in BIPV:
In agricultural photovoltaic greenhouses, PC sheets and solar panels work together. While PV panels generate electricity, PC sheets provide essential light transmission for plant growth. The optimal ratio depends on crop light requirements — typically 30–50% light transmission is ideal for most greenhouse vegetables.
For industrial factory rooftops, PC daylighting strips complement large-scale PV installations. This hybrid approach maximizes roof utilization: PV panels cover 70–80% of roof area for power generation, while PC strips illuminate work areas below.
Best PC Sheet Specifications for BIPV Applications
Key Parameters for BIPV-Ready PC Sheets:
Critical BIPV Requirements:
- UV Stability: Must match 25+ year solar panel lifespan
- Thermal Performance: Low thermal conductivity (≤0.2 W/m·K)
- Mechanical Strength: Withstand wind loads and thermal expansion
- Light Control: Precise transmittance for plant or human comfort needs
PC Sheet vs Glass: BIPV Material Comparison
Cost Analysis:
PC sheets typically reduce BIPV system costs by 15–25% compared to all-glass solutions, primarily through savings in structural support and installation labor.

BIPV PC Sheets FAQ
Q: What thickness of PC sheet is best for solar greenhouses?
A: For most crop greenhouses, 6–10mm PC sheets with 80–85% transmittance provide optimal balance between light and insulation. Fruiting vegetables may require higher light (85–89%), while leafy greens thrive with 70–80%.
Q: Can PC sheets withstand hail in BIPV applications?
A: Yes. Premium PC sheets with impact resistance of 250× glass can withstand 25mm hail at terminal velocity without damage. Always verify impact test certifications.
Q: How long do PC sheets last in outdoor BIPV applications?
A: Quality PC sheets with proper UV protection (≥50μm co-extrusion) typically maintain 80%+ transmittance for 15–20 years. Glass alternatives last longer but cost significantly more.
Q: Are PC sheets fire-rated for BIPV roof applications?
A: Yes. B1-rated (highest flame retardancy for construction) PC sheets are available and recommended for all building applications. Request flame test certificates from suppliers.
