Difference between SolarEdge and string Inverter in loss diagram.

[Chae Han Lee]

Hello,

The simulation was conducted using the same Near Shadings (*.SHD) and Horizon to find out the difference in power generation between the SolarEdge inverter and the normal string inverter.
According to the loss diagram among the simulation results, [Near-shadings:irradiance loss] is different. (SolarEdge: -5.26%, String Inverter: -6.32%)
I would like to ask if Near-shadings:irradiance loss should be the same because it was simulated using the same Nearshadings and Horizon.

They should be the same, if the 3D scene, horizon, MET file are the same. Did you change anything else except the inverters?

Thanks for reply.

I didn't change anything except inverter.

Add new variant in project and import old variant.

Were they simulated in the same version?
If so I invite you to send us the project for review at support@pvsyst.com
