Modelling annual yields of a solar-tracking solar syphon using ASHRAE’s weather data for tropical Africa

Abstract

This work is a follow on to previous ones on solar tracking in Tropical Africa by the authors. While the first work showed the necessity to replace current fixed panels/collectors with two slope fixed installations at prescribed angles and times, the second established the need for - and determined the constraining techno-economic factors of tracking photovoltaic panels in rural Africa. This paper covers the introductory part of trackingpassive flat collectors as would be applied in hot water cylinders (domestic water geysers) in these areas.
