Zambia and Ethiopia are two countries from southern and eastern of Africa due to their geographical location and other factor the environment condition is different. The research aims to Investigation how operational and climatic factor affect PV-grid tied inverter. In Zambia the study focused on...

Sustainable hydropower development provides a reliable and stable power source that is economical and environmentally friendly. However, its investment capital is huge and unbearable to third-world countries. Hence the requirement of an alternative power source that is manageable. Zambia’s main...

The agricultural sector in most developing countries encounters a lot of post-harvest losses due to a lack of appropriate drying and storage facilities for preservation. Though many drying technologies have been developed, there is an increasing demand for automation in drying. Concerning this...

In an effort to mitigate post-harvest losses (PHL) of agricultural products from farmers and the markets, greenhouse solar dryers (GSD) have been extensively employed by various stakeholders. The operation of these conventional GSD is though allowing cool or cold ambient air to enter them during...

Access to electricity is one of the main drivers in the process of sustainable development. Access to energy transforms the lives of people, communities, and nations. The main issue facing developing countries is the lack of access to affordable and reliable electricity supply for their...

The telecommunications industry in Zimbabwe keeps growing with an increase in the number of users yearly. The demand on the national grid and low power supply means long hours of electricity outages, which prompts Internet Service Providers (ISP’s) to use generators as backup power to keep base...

The Zambian electricity grid system has been dominated by hydropower at 96 %, 2.1 % thermal and 1.7 % renewable (Kaluminiana, n.d.). During the 2014 - 2015 rainy season, Zambia received very low rains which led to reduced electricity production at the two major power plants. In the light of this...

Utility scale Solar PV power generation is for the first time being added onto the Zambian national electricity grid to increase capacity of electricity generation and to reduce over dependence on hydropower generation. The World Bank group recently funded a ‘Solar Photovoltaic (PV) Utility Scale...

The Government of the Republic of Zambia (GRZ) has set an ambitious target of raising the rural electrification rate from 3.4% (in 2008) to 51% by the year 2030.However, as at 2017 - almost 10 years down the line, the Rural Electrification Authority (REA) indicated that access to electricity in...

Mini hydropower plays a critical role in providing energy access to remote areas through mini grids. However, the development of mini hydropower sites has lagged in Zambia with the country only witnessing the construction of two off-grid mini hydropower stations namely, Zengamina and Shiwan’gandu...
