Normalised balance of system loss

The balance of system loss expressed as a per-day value.

The balance of systems (BOS) loss L_BOS represents the losses in the BOS components, including the inverter and all wiring and junction boxes not included in array capture loss.

It is calculated as the difference between the PV array energy yield and the final system yield.
