Karina Suharevska Posted September 15, 2022 Report Share Posted September 15, 2022 Hello! I made one solar plant with 1820 solar panels, each 450W. Total output 819kW with spec.annual yield 855,61 kwh/kwp. Grid feed in 700 955 kwh/year. Then I changed all 1820 panels to 460W. Then total output was 837,20kW with spec.annual yield 831,37 kwh/kwp. Grid feed in 696 232 kwh/year. My question - why the spec.annual yield and grid feed in drop off so much ? I am concerned because, the power of one module became bigger, but the spec. annual yield decreased. Please see file attached. Quote Link to comment Share on other sites More sharing options...
