A study released by the Energy Platform Studies Center for Labor and Agrarian Development (CEDLA) reveals that 97 percent of Bolivia’s territory is suitable for solar energy use, thanks to high solar radiation levels in large part of Bolivia.
“It can be concluded that the use of solar energy level throughout the country is possible, except for some areas that constitute less than 3 percent of national territory,” says the study “The role and impact energies socioeconomic renewable rural Bolivia. ”
Research carried out by Miguel Fernández Sources identified that the only space “impracticable” for the use of solar energy is the cloud-forming regions located in the eastern belts of the Cordillera de Los Andes, at the low rate of solar radiation.
The high values of solar radiation in Bolivia, according to a study published in 2011, are due to the geographical position that has the land, which is located in the tropical South, between parallels 11 ° and 22 °. Therefore, the radiation rate between winter and summer season does not represent differences that exceed 25 percent.
The document notes that in the country, the average values of solar radiation vary for the highland areas, valleys and plains. The areas of the plateau region showed the highest rate of radiation, which decreases towards the plain areas.
“In Bolivia, the highland regions and the valleys are a high rate of solar radiation between 5 and 6 kWh/m2d (kilowatt-hours per square meter per day), depending on the time of year. In the plains area average radiation rate is between 4.5 and 5 kWh/m2d. This energy is sufficient to provide daily 220 Wh / day of electricity through a 50 Wp PV panel, “the technical explanation.
