  • Performance data is based on representative samples of factory production. Actual values may vary slightly due to variations in the production process.
  • Tabulated data is based on NRFC methodology using the LBL Windows 5.2 Software and where noted European methodology using WinDat WIS version 3.0.1 software.
  • SF = Solar Factor (EN410) also known as g-value.
