bernard Posted September 18, 2015 Report Share Posted September 18, 2015 Hi,I would like to conduct an analysis of fixed tilt Photovoltaic array.I need a weather file for particular location. It can not be found in the PV*SOL Climate data.But Meteonorm has it. The problem is that this Meteonorm weather file does not contain data about snow depth nor albedos.I was wondering if I could approximate this by somehow defining an albedo to be 0.6 (ground covered with wet snow) in cases when air temperature is bellow some value.Which value would that be? Something bellow 0°C. Basically when this air temperature value is present, there is snow on the ground, and when it's higher than this value, there's no snow. RETscreen advices using 0.7 albedo for -5°C temperatures, and interpolated albedo values from 0.7 to 0.2 for air temperatures between -5°C and 0°C (example: -4°C - 0.6, -3°C - 0.5, -2°C - 0.4, -1°C - 0.3, 0°C - 0.2, 1°C - 0.2...).Do you think this is correct?Any recommendations please?Thank you for the reply.
