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...

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...

Climate change has greatly affected Zambia’s hydropower production. This has contributed to reduced amounts of electricity being injected into the utility grid. Zambia has therefore embarked on igniting different solar energy initiatives. However, no critical study has been done to document the...

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...

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...
