Energy is a key factor for the development of a country. In many remote areas of the third world with good insolation such as Uganda, photovoltaic is one of the most suitable ways of providing energy to rural areas. The government of Uganda is actually pushing what is called “Rural Electrification, Strategy and Plan” to foster a massive purchase and use of Solar Home Systems. Nonetheless, in order to spread photovoltaic technology, one of the main difficulties of a country is the lack of proper framework for importation of the components, maintenance, and data on technical performance of these components. This paper does a national survey on local manufacturers of deep-cycle batteries, charge controllers, lights and inverters; panels are not available as yet and it won’t be in a foreseeable future. Given the importers possibilities, it also does an economic analysis comparing products from China, India, Europe and USA, taking into account the actual governmental position in terms of taxes on photovoltaic products. Some valuable data are presented on the experiences of NGO’s and local communities; how successful have they been, problems they face, etc. The concern about quality and the idea of providing the costumer with a reliable product drove the authors also to analyze the documents of the Uganda National Bureau of Standard establishing national standards and minimal warranty for all components related with solar energy and write some few considerations. Finally, taking advantage of other countries experiences a specific solar home system is designed for Uganda users

The rural electrification in Uganda is facing an enormous challenge following the ongoing process of privatisation/liberalisation of the power sector. The Electricity Act enacted in November 1999 provides for more power utilities in the generation, transmission and distribution of electricity, ending a more than 40 years of monopoly of Uganda Electricity Board (UEB), a government parastatal. One of the consequences of this Act is that rural electrification pass to be responsibility of the Ministry of Energy and Mineral Development. This ministry issued a document “Rural Electrification, Strategy and Plan”[1] whose overall objective is to increase electricity accessibility in the rural areas from the actual less than 1% to 10% within 10 years. It supposes to electrify 300,000 new rural households. This objective is meant to be achieved using gridextension, mini-grids and photovoltaic solar systems. This present paper considers the possibility of using SWER for grid-extension and mini-grids aiming at reducing costs. Technical and regulatory aspects are presented.
