The “SolarBots and Status Data” custom report type doesn't have the correct relationship between the correct objects.

@Avuja Jamuna  You have to go to Object Manager and Then Opportunity Object, In Opportunity Object you have to select the field "Type", When you click Type, you can see the picklist value SolarBot there. Just check whether you have that value or not, If not you have to create one Piclist value of SolarBoat in the Opportunity Object's Field Type[ picklist].
