Transforming　the　road　public　transport　to　run　on　renewable　energy　is　vital　solution　to　achieve　carbon　neutral　and　net　zero　goals.　This　paper　evaluates　the　potential　of　using　solar　radiation-generated　electricity　as　an　auxiliary　power　supplementary　for　the　battery　of　electric　buses,　based　on　a　developed　framework　that　using　publicly　street-view　panoramas,　GPS　trajectory　data　and　DEM　data　as　input　parameters　of　solar　radiation　model.　A　case　study　of　Qingdao,　China　with　547　bus　routes,　28,661　street-view　panoramas　shows　that　the　solar-radiation　electricity　generated　at　noon　during　the　operation　accounts　for　about　one-fifth,　one-eighth　of　the　total　elec-tricity　consumption　of　a　bus　traveling　one　kilometer　in　a　sunny　day　and　a　cloudy　day,　respectively.　Spatial　variability　shows　significant　solar-radiation　power　generation　advantages　in　newly-launched　areas　and　expressway.　The　solar　power　generated　in　a　sunny　day　can　make　a　bus　half　of　passengers　and　with　air　conditioner　off　at　least　one　extra　trip　in　2:1　replacement　schedule,　and　nearly　close　to　one　extra　trip　in　4:3　replacement　schedule.　A　correlated　relation　between　the　solar-radiation　power　generation　benefit　and　the　operation　schedule　of　electric　buses　is　observed,　implying　that　the　high　cost　of　2:1　replacement　schedule　for　long-distance　routes　during　summer　or　winter　can　be　reduced.　The　proposed　framework　can　help　us　evaluate　and　understand　the　feasibility　of　solar　radiation-generated　electricity　energy　of　electric　bus　fleets　covering　the　large-scale　urban　areas　at　different　times,　locations,　and　weather　conditions,　so　as　to　support　effective　decisions　at　better　planning　of　PV-integrated　electric　buses.
