Product Description

10KW Solar Power System For BTS Power Supply


Photovoltaic power system for base station consists of photovoltaic modules, brackets junction boxes, charge controller, battery pack and inverter and so on.

A photovoltaic module usually uses monocrystalline silicon or polycrystalline silicon cells, and a single cell has an output voltage of 0.5V. As a module is mainly composed of 72 pieces of solar cells in series, two modules should be connected serially to get output voltages ranging from 43.2V to 56.4V. Modules with relatively large capacities such as 165W, 170W and 175W are preferred. The quantity of parallel connected modules depends on load capacities and solar power resources.


Photovoltaic modules are supported by zinc coated steel brackets, which fix the modules at a certain angle. Independent photovoltaic system should be placed at an angle of 10-20 degrees higher than the latitude of the site for maximum solar radiation in winter so as to reduce the number of batteries and the cost of the whole power system.


Battery will feed loads when the solar power is not enough due to shortage of sunshine, which is common on rainy days and nights. Capacity of battery group depends on such parameters as load capacity, backup time, discharge depth, safety requirement and so on.


OPzS battery used to be the choice of solar power system as it employs positive tubular plates that can prevent the active material from falling off and thick pasted negative plates that ensure a long service life. However, OPzV with positive tubular plates gradually become popular in recent years as less maintenance is needed.


Multi-channel controller is used in charge/discharge management, and solar array is divided into several sub-arrays, which are connected to the controller via conjunction box. When battery is fully charged, the controller will cut off solar sub-arrays one by one; then battery and the rest of the photovoltaic sub-arrays provide power for the loads together. When the voltage of the battery falls to the set value, the controller will reconnect solar sub-arrays one by one to adjust the charging voltage and current of the battery.

Case Study

Showing a photovoltaic power system in Pakistan provided by GPOWER

The maximum continuous rainy/cloudy days in the local area is 5 days; power system is required to provide power for BTS and microwave equipment; the total power consumption is 550W. According to the requirement mentioned above, the system configuration is given as:


Photovoltaic module: 16 pieces of 320W monocrystalline cells;

Battery: Two groups of 2V/1000Ah Gel OPzV;

Charge controller: 48V/150A controller.


In this project, 22 solar-powered BTSs are deployed. They have a relatively small capacity, which is in the range of 400-900W. If diesel generator is adopted, the conversion efficiency will be very low as the capacity is small, and the power supply reliability is also very low. Solar power system makes diesel re-fuelling and maintenance work unnecessary, which can save about US$150,000 for operator every year.


Since 2012, GPOWER has helped over 40 operators in more than 20 countries build solar-powered BTS system in areas without enough power supply, to meet the communication needs of local people and improve their living standards.
