This document describes a high level technical design for and the economic assessment of renewable
energy solutions for radio base stations (RBS). It proposes a way forward in the development of
'hybrid' solutions with renewable energy sources (RES) for off-grid RBS sites.
The main purpose of this document is to provide initial practical, technical and economic guidance.
The following sections outline the specific requirements of mobile operators and provide specific
technical guidance for the selection and implementation of the elements of a hybrid system.
This information will enable mobile operators without any detailed technical and commercial
knowledge to develop initial ideas on the design of such a system and provide them with a common
basis for further discussion, evaluation and benchmarking.
