SOLAR POWER FOR TELECOMMNUCATION NETWORKS
Solar power for telecommunication networks is another application for solar photovoltaic. The
telecommunication BTS towers have power supply from Diesel Generators in areas where no grid is
available and have back up diesel generators where grid is available. Operational Expense of power
generator is very high. The best replacement of the diesel back up is the solar power which is clean energy.
These systems can be hybrid (solar and wind) where wind is available. Many telecom operators have
installed solar systems and they are very much satisfied and many are still in the process of planning for
purchase of solar power systems. Again designing of solar solution for BYS towers is a specialized job.
