First Solar TetraSun™ Module

Unprecedented Performance in Restricted Spaces and Distributed Generation

Technologies & Capabilities /  Advanced PV Modules /  First Solar TetraSun Module
The First Solar TetraSun™ Module is designed for applications where space is at a premium or customers prefer a high-power density solution. With a proprietary cell architecture and manufacturing process, our crystalline modules offer one of the industry’s highest power ratings and lowest temperature coefficients, resulting in superior energy density in space-constrained installations. With lower installation costs, faster installation times, and greater system revenues, our crystalline modules will deliver unparalleled value for our customers.

Proprietary cell enables efficiencies over 21% and module designs with superior power density compared to standard crystalline silicon

Streamlined manufacturing process versus other approaches to high-efficiency reduces complexity and improves product consistency and performance

  • Manufactured using high-purity, large form factor (156mm) n-type wafers with higher efficiencies than p-type mono-crystalline  cells due to a higher minority carrier lifetime
  • 156mm wafers provide more active cell area per module and increased power output than standard 125mm wafers
  • Metallization process utilizes less than 50μ narrow copper electrodes with superior conductivity and less resistive losses than industry-standard, screen-printed silver fingers
  • Copper-plated metallization induces minimal stress on wafers, improving mechanical yield and reliability

Superior energy harvest compared to standard crystalline silicon technologies

  • Lower temperature coefficient (-0.3%/ °C) results in superior energy production compared to standard crystalline technologies (typical -0.45%/°C)
  • No light-induced degradation
  • No potential-induced degradation
