tilt determination via location_to_tilt() does not have a default option for non-South azimuths: https://jugit.fz-juelich.de/iek-3/shared-code/RESKit/-/blob/dev/reskit/solar/core/system_design.py#L8
Nobody builds an East-West plant with such high tilts as we get them for South-facing plants in Europe. Adding another (or an improved) convention for East-West plants or generally non-South would enable us to actually compare performances and grid stabilization impacts.
