First published in 2008, the first edition has been used to train more than ten thousand engineers and field technicians to install and maintain such systems. The newest edition of this practical manual is enriched with new field experiences and accurate and up-to-date information.
Nearly one third of humanity still live in semi-darkness after sunset, no better off than in earlier centuries, mainly because they are beyond the reach of mains electricity. The traditional forms of lighting such as candles, oil lamps, kerosene pressure lamps, butane lamps tend to be inefficient and inadequate for many applications.Recent technical developments in electrical lighting have led to exciting new possibilities such as highefficiency compact fluorescent lamps. Such lamps can increase the economic use of solar photovoltaic power systems or small wind-powered systems. These, and other new lighting technologies are becoming available and more affordable, but it can be difficult to know which types and sizes are most appropriate for different purposes.To meet these needs, Rural Lighting provides information to assist development workers and project managers working in rural or semi-urban development, health, farming, small business sectors to decide:ΓÇó What level of light is necessary to meet the needs.ΓÇó Which type of lighting sources would be most suitable.ΓÇó How to provide small amounts of power for lightingΓÇó How to implement cost-effective lighting systemsRural Lighting also includes an illustrated Buyers Guide'' section providing up-to-date information on lighting systems and products available and listing addresses of manufacturers in many countries around the world.
An ideal addition to the toolkit of anyone involved in the installation of solar powered photovoltaic systems, this practical guide provides step-by-step explanations of the process by which technicians can estimate the requirements of PV systems and guides the reader through the set-up and running of such systems.
