Solar photovoltaic energy
PV applications in lesser developed countries
lighting and power supplies for remote building (mosques, churches, temples etc farms,
schools, mountain refuge huts) - low wattage fluorescent or LED lighting is recommended:
power supplies for remote villages:
individual house systems (solar home systems):
See the Practical Action Technical Brief Rural Lighting
Water pumping and treatment systems
pumping for drinking water:
pumping for irrigation:
dewatering and drainage:
saltwater desalination systems:
See the Practical Action Technical Brief Solar PV Waterpumping
Health care systems
lighting in rural clinics:
UHF transceivers between health centres:
ice pack freezing for vaccine carriers:
blood storage refrigerator.
PV is frequently used to power vaccine refrigeration in remote health centres. See the Practical
Action Technical Brief Solar Photovoltaic Refrigeration of Vaccines.
remote TV and radio receivers:
