The aim of the work was to find out the functionality of LED lighting combined with solar panels in developing countries and to find out the availability of solar energy in different geographical locations. Another aim of the work was to understand the advantages and disadvantages of photovoltaic systems and the optimum combination of PV systems for lighting. Measurements of photovoltaic systems combined with LEDs and fluorescent lighting were conducted in an office building in Finland. Measurements in a one-room house in Sudan using LEDs and fluorescent and incandescent lamps were also conducted. The costs analysis comparing photovoltaics and diesel generators in Sudan are discussed. The results showed that in Finnish conditions photovoltaic systems may be combined with AC power sources and DC rectifiers. However, in Sudanese conditions, where solar radiation is available all the year round, photovoltaic systems can be used without inverters. LED lighting combined with solar panels was found to be suitable for lighting in developing countries. Photovoltaic systems have shown high potential for electricity generation in Sudan.
