jeffn Posted June 26, 2015 Author Posted June 26, 2015 There is no project to send. This bug is in the Heterogeneous Arrays Tool, as the subject line indicates.For example, use the following settings:Array nb 1 Mfr: Trina Solar PAN: Trina_TSM_305_P14A.PAN Nb modules in Series: 2 (This is the ONLY one that really matters) In parallel: 1 Plane Tilt: 30 Azimuth: 0 Albedo: 0.20Array nb 2 Mfr: Trina Solar PAN: Trina_TSM_305_P14A.PAN Nb modules in Series: 1 In parallel: 1 Plane Tilt: 30 Azimuth: 0 Albedo: 0.20Incident Irradiation Site: Detroit Date: June 26, 2015 Fraction of Clear Sky Irradiation: 100% Diffuse Fraction: 15%Click the Graph button. In 6.38 the "Resultant Pmp" is 587W and loss is reported as 100%, but in 6.25 the Pmp is 584W and loss is reported as 43.1%.
André Mermoud Posted June 28, 2015 Posted June 28, 2015 Thank you for this information. I have corrected for the next version 6.39.
