### Energy Generated by Solar Photovoltaic Systems in the Regions of Putumayo
According to these data in 2018 on average one person in each municipality of Putumayo consumed 213 kWh of residential electric energy per year. With this consumption and an installation of a 1 kW solar system, such as the one described in Table 6, the demand of three people in the Andean region and six people in the Amazon region could be supplied. By comparison, compiling the costs of electric energy from the SUI found that in the zones connected to the national grid in the department of Putumayo, the costs are above the Colombian average, and the costs of the ZNI of Putumayo are higher, almost tripling the costs of the national average (see Table 11). The costs of electric energy in Colombia are increasing yearly. From 2017 to 2018 they went up approximately 5%, while the costs of solar energy, according to IRENA, decreased. Therefore, over the last 10 years this decrease \begin{table}

Table 9: Residential consumption of the areas connected to the national electricity grid and the ZNI in the department of Putumayo. was 82%, and from 2018 to 2019 it was 13%, reaching almost seven cents (USD 0.068) per kWh [36]. Now, if we considering 25 years of solar system lifetime, return rate of 12%, a capital of USD 1000, operation, maintenance, and other associated cost at 1%, a capacity factor of 16%, the obtained value of LCOE from Equation (13), whit the energy generated for this type of solar photovoltaic systems, is of 0.10 USD/kWh.
