Abstract: A photovoltaic horizontal beehive system provides a horizontal beehive. The brooder box has sidewalls and a floor wall that form an interior cavity. The cavity is segregated into independent compartments through a central fixed divider, and multiple removable dividers that segregate the brooder box into a queen bee colony and a honey bee colony. The removable dividers are manipulated in the cavity to adjust the size of each compartment to accommodate population changes in the bee colonies. A lid regulates access to the interior cavity. A solar panel operates on outer surface of lid. The solar panel harnesses sunlight to generate electricity used internally and externally of the brooder box. An electrical compartment in brooder box retains electrical components, like a battery, an inverter, and a charge controller. The solar-generated electricity is used internally for operation of an internal beehive apparatus, and carried distally to operate an external electrical apparatus.
