Renewable energy often referred to as clean energy, is an important energy source that comes from natural sources or processes that are constantly replenished such as solar, wind, geothermal and hydro-based energy. Zambia’s installed energy capacity stands at 2,800 Megawatts (MW) of which 85...

Solar energy plays a vital role in reducing energy deficits by providing a renewable and sustainable power source, and it significantly reduces contributions to climate change compared to fossil fuels. A deeper understanding of the concepts involved in the study of solar energy is crucial for the...

Zambia's National access to electricity is approximately 31 %, with 67 % of the urban having access and worse off in rural areas, which are very remote and far away from the electricity grid, with only 4 % of its population having access. Rural areas do not just need electricity for everyday uses...

Well-illuminated streets play a vital role in enhancing the security and well-being of residents in cities and towns. Investing in solar street lighting can reduce costs spent on grid electricity bills. It can also enhance safety and security at the same time uplift the economy of, women and men...

The power utility company in Zambia, the Zambia Electricity Supply Corporation (ZESCO) introduced load-shedding in urban and rural areas in 2015 when the country experienced severe drought and caused low water levels in our hydropower stations for power generation and distribution. To mitigate...

The Solar mini-grid initiatives aim to provide access to electricity to rural and remote areas which are currently not connected to the national grid. However, the implementation of solar mini-grids in Zambia presents challenges and therefore understanding the success factors and challenges of...

One of the major problems in concentrating solar radiation on the Photovoltaic (PV) module is the uneven illumination of the solar cells. The non – uniform irradiance creates hot spots on the module and increases its temperature. The high temperature results in a lower efficiency and increases...

In this work, a report is given of a centralized smart metering system intended to run an algorithm designed to address the problem of peak-hour energy deficit in Zambia. A survey study conducted in Lusaka to establish household power-usage patterns led to the development of the load-management...

The traditional high concentrating photovoltaic systems have proved to be expensive as they use high grade silicon solar cells, highly specular reflecting materials and require tracking arrangements which are equally expensive. The problem of un-even illumination creates heat-sinks which have not...

The production of energy from fossil fuels and nuclear materials has environmental drawbacks. These drawbacks include the creation of nuclear waste and the pollution associated with fossil fuels which lead to global warming and climate change. It is apparent that alternative and sustainable...
