Draft Standards on Solar Photovoltaic (SPV) Power Supply
for Telecom Equipment Issued by TEC (08 Aug)
The Telecommunication Engineering Centre (TEC), under the
Department of Telecommunications (DoT), has circulated draft
Standards titled Generic Requirements (GR) on Solar Photovoltaic
(SPV) Power Supply for Telecom Equipment's (Standard No. TEC
66090:2025, revision of TEC 66090:2017). These Standards define the
requirements for SPV power systems catering to telecom equipment
operating at 12V, 24V, or 48V DC, covering load capacities up to
20A continuous or 480 AH per day. The SPV system includes solar
modules, battery banks, charge controllers, and hybrid arrangements
with float chargers for a regulated DC power supply. The initiative
seeks to ensure reliable, sustainable, and non-conventional power
solutions for telecom applications. Comments are invited within 60
days from the notification, that is, by 7th October
