Technical background
The clean energy provided by the solar photovoltaic power is the new energy that is concerned and extensively used by the mobile communication at the era of 3G and 4G. As the particularity of the power supply requirements of the mobile communication base station, the solar light source becomes one of the preferred energy for the power supply of the mobile communication base station. Along with the continuous development and progress of science and technology, the solar photovoltaic electric power industry has grown into the leading industry of new energy, and been extensively promoted and applied in the communication field. The project is the third generation intelligent device system generated through the deepened research and development based on the high-tech achievement project in ***2 Power-Supply Device System Project for Solar Mobile Communication Unattended Base Station, which is developed, promoted and applied by Ministry of Information Industry. The project has become the best solution for the third generation power supply device of mobile communication.

Functional characteristics
Intelligent base station equipment system of the solar mobile communication box-type substation (hereinafter referred to as solar box-type substation) integrates such devices as solar photovoltaic power generation equipment, internet transmission equipment, switch power supply electrical equipment of the substation of *2KV below, BTS transceiver equipment, optical cable transmission equipment, computer protection monitoring equipment, multimedia DC switch power supply equipment, lightning grounding equipment, fire fighting security inspection equipment, lighting and air conditioning devices, etc, in the totally enclosed metal box of thermal insulation, radiation protection, waterproof and moisture proof, so as to combine into an intelligent mobile communication special base station room. The solar-cell panel square matrix with area of *0m2 is installed on the top of the box and iron tower of the base station, the power generation efficiency of the solar-cell panel is 6KWh. A mobile communication photovoltaic power station is made up of the above devices, and the box bodies of the box-type substations are combined into a complete mobile communication base station room. Wind power generation equipments of more than 6KW are installed in the mountain pass region, river shoal and gorge region and famous mountain tourist attractions with the wind resources, to form a wind-solar hybrid new energy power grid. Therefore, the solar box-type substation is not only a photovoltaic power generation station with 6KWh**0KWh power generating capacity and a wind-solar hybrid new energy power station, but also a mobile communication base station with the capacity of more than 8 carrier frequency, it is a new generation intelligent mobile communication equipment system with the wholly integrated system and photovoltaic telecommunication integration, energy saving and environmental protection.
Solar box-type substation is featured with unique design, attractive appearance, compact structure, energy saving and environmental protection, convenient installation and maintenance, strong box, security and guard against theft. Product can be integrated, pre-assembled and produced in the factory, it is the best equipment for the construction engineering of the mobile communication base station, with strong practicability, extensive promotion and application, it is the best implementation program for the mobile communication industry to accomplish the national energy saving and emission reduction targets.
