This　study　aims　to　establish　a　novel　solar　air　collection-cascade　storage　system.　Flat-plate　micro-heat　pipe　arrays　are　applied　in　collector　and　heat　storage　units　for　heat　transfer　enhancement.　To　increase　energy　utilization　ratio　and　improve　system　stability,　a　cascade　storage　configuration　using　paraffin　and　lauric　acid　is　adopted.　In　the　charging　process,　the　cascade　heat　storage　units　store　the　solar　irradiance　collected　by　the　collector　in　the　phase　change　materials　through　the　heat　exchange　fluid　(air).　During　the　discharging　process,　air　takes　away　the　heat　stored　in　the　phase　change　material.　The　heat　transfer　process　and　thermal　performance　of　the　system　was　analyzed　experimentally　in　different　volume　flow　rates　from　the　perspectives　of　energy　and　exergy.　The　experimental　results　show　that　the　air　flow　rate　affects　the　thermal　performance　of　the　system　significantly:　as　the　volume　flow　rate　increases,　the　heat　collection　power　and　efficiency　show　an　upward　trend,　and　the　heat　storage　power　and　heat　storage　efficiency　also　show　an　increasing　trend.　Contrary　to　the　increasing　trend　of　exergy　storage　efficiency,　exergy　extraction　efficiency　decreases　with　increasing　volume　flow　rate.　An　airflow　rate　of　220　m(3)/h　obtains　the　highest　average　heat　collection　power　and　average　heat　collection　efficiency,　which　are　542.0　W　and　35.8%,　respectively.　In　this　condition,　the　average　heat　storage　power　and　average　heat　storage　efficiency　of　latent　heat　storage　unit　I　are　175.1　W　and　67.5%,　respectively,　and　those　of　unit　II　are　136.0　W　and　87.5%,　respectively.
