This paper examines solar energy solutions for different generations of mobile communications by conducting a comparative analysis of solar-powered BSs based on three aspects: architecture, energy production, and optimal system cost.
The communication base station installs solar panels outdoors, and adds MPPT solar controllers and other equipment in the computer room. The power generated by solar energy is used by the DC load of the base station computer room, and the insufficient power is.
These cables are commonly deployed in wireless base stations and mobile networks, including 4G, 5G, and LTE systems. They are suitable for outdoor fiber optic installations that require waterproof and dustproof connections, as well as long-distance, high-bandwidth data transmission.
Both units can be powered by the vehicle's DC bus, accepting 11 to 33VDC, while the BST35 is powered by a 70Wh internal Lithium Ion battery which provides up to 10h of continuous operation. The battery is charged through a USB-C charger or the vehicle's DC bus.
The recommended approach is to use a separate DC grounding electrodefor PV arrays and frames,as this enhances protection against lightning and transient voltage. For lightning protection associated with grounding systems,refer to NFPA 780 and NEC 250.
The protection of GSM and base station towers from lightning and overvoltage is provided by integrating external lightning systems, internal lightning systems, earthing, equipotential bonding and LV surge arrester protection techniques within the framework of IEC-62305 standard.
A wind-solar hybrid and communication base station technology, which is applied in photovoltaic power plants, wireless communications, photovoltaic power generation, etc. , can solve the difficulties of disassembly and assembly of wind-solar hybrid self-powered.
