There are projects that are promoting WLEDs lamps technology powered with photovoltaic modules, which are reporting excellent technical results. However, the high initial cost, compared with fuel- based lighting, is a barrier to achieve them, so other evaluation methods must be used such . . .

However, the basic results demonstrate that a PV LED lighting system represents a lower cost option for off-grid lighting systems, with a present value LCC of about $330, which is about half of the LLC for fluorescent lamps of over $700.

Emerging high efficiency WLED technologies can significantly improve the quality, safety, and quantity of illumination for both rural and urban homes, while reducing overall costs and environmental emissions. PV modules are the best option to power WLEDs lamps in rural areas, since they can be installed at the site where the energy is needed and no further . . .
