Apollo Solar designs and manufactures energy systems for Remote Mobile Telecom Towers. Starting in September 2012, Camusat has installed these systems on towers owned by Orange. With over 1,000 systems now running, some for the entire six-year period, the results in terms of reliability, cost, battery life and greenhouse gas avoidance are statistically significant. The installations are spread over seven countries in Africa, which include challenging climates. This case study, submitted by Apollo Solar CEO John Pfeifer, will identify the principle results, and comes at a timely moment as MNOs and towercos contemplate the economic, social and regulatory burdens associated with continued reliance on fossil fuels.
