[EnergyPlus_Support] Re: small (5kW) wind turbines in E+ v5

Hi Jeremiah,

Weather data was the issue! I'd used Meteonorm to generate an EPW but not generated the DDY file that E+ uses to normalise the yield.

I used the E+ weather tool to create the DDY and found a resolution.

Thanks for your help

Chris
