6. External Temperature The external temperature is a specification taken from the climate data files It is required to define the module temperature as the module efficiency is dependent on the temperature see PV Module parameters Grid Feed in The energy generated on the AC side of the PV array is the energy produced by the invertor and fed into the network Corresponds to the PY array generator power AC Grid minus own consumption Dr Valentin EnergieSoftware GmbH 76 82 Manual PV SOL basic 6 0 14 Glossary Incident Angle Modifier 96 IAM The incident angle modifier is a characteristic of the material covering the module glass The angle to measure the IAM is 50 between the ray and an orthohonal of the module surface 40 between panel and ray The glass reflects part of the radiation away from the module resulting in a loss of current The incident angle modifier reduces the amount of direct radiation falling onto the module The correction factor for diffuse radiation lost through reflection is assumed at 9596 Internal Rate of Return The yield represents the ratio of payments to the deposit of money or capital investment Basis of calculating the yield of a solar system is the profit that is set in relation to investment The return on assets provides an overview of the return on total investment The yield is a key indicator for assessing the viability of a solar system The nternal Rate of Return is calculated accordi
