Jan 13 (Reuters) - David Tepper-led hedge fund Appaloosa
Management LP sued to prevent SunEdison Inc's SUNE.N yieldco
from taking over some of Vivint Solar Inc's VSLR.N assets
after SunEdison acquires the rooftop panel installer.
The yieldco, TerraForm Power Inc TERP.O , is to acquire
Vivint's residential solar rooftop portfolio after SunEdison
completes its acquisition of Vivint.
SunEdison offered to buy Vivint in July.
