Cellular network operators are always seeking to increase the area of coverage their networks, open up new markets and provide services potential customers in remote rural areas. However, increased energy consumption, operator cost environmental impact greenhouse gas emissions exhaustion non-renewable resources (fossil fuel) pose major challenges cellular operators. The specific power supply needs for base stations (BSs) such as cost-effectiveness, efficiency, sustainability reliability can be satisfied by taking advantage technological advances renewable energy. This study investigates possibility decreasing both operational expenditure (OPEX) with guaranteed BSs using a solar photovoltaic/diesel generator hybrid system. Three key aspects have been investigated: (i) yield, (ii) economic factors (iii) emissions. results showed benefits mobile terms conservation OPEX reduction, an average annual savings 43% 47% based on characteristics radiation exposure Malaysia. Finally, paper compares feasibility proposed approach four-season country against obtained Malaysia, which is tropical climate.
