The installation has cost 38,814 euros and it has had the support of the Canary Islands Operational Program with funds from the European Union to improve energy efficiency and reduce CO2 emissions in buildings and infrastructures and public services. The Deputy Mayor of Los Realejos, Adolfo Gonzalez, and the councilor for Urbanism and Industry, Laura Lima, visited yesterday the educational center in which this photovoltaic installation of 45 nominal kilowatts was executed, «whose start-up will propitiate a saving in energy consumption of 82% per year and a reduction of pollutants of more than 15 tons of annual emissions of carbon dioxide (CO2) into the atmosphere is estimated, going from the average of 18,514 kilos a year to 3,321 kilos a year ».
«We are talking, therefore, of an initiative that supposes a significant initial investment, in this case supported by financing with European funds, but since its inception it begins to generate results in economic savings, energy savings and reduction of pollution. According to technical data provided by the previous study, the photovoltaic panels of CEIP Agustín Espinosa They will be able to supply a large part of the center’s own energy needs, and also pour excess compensation into the grid ”, emphasizes González.
The new photovoltaic installation will be capable of generating about 72,900 kilowatt hours per year
«In line with the declaration of the climate emergency and the different actions to which the Los Realejos Town Hall Due to energy efficiency and the reduction of pollution, various studies of renewable energy potentials have been proposed in different public facilities in the town for their implementation. The CEIP Agustín Espinosa is one of the educational infrastructures with the largest roof area, so it was the appropriate school center to start a block of projects of this type, which already exist on the roof of the consistory itself or in the Basilio Labrador sports complex».
Los Realejos City Council launched a similar pilot experience in the CEIP Toscal Longuera, but that does not reach such a percentage of self-sufficiency in the center. In addition, it has drawn up other similar projects for the other public schools in the municipality that it will present shortly to the last call for European funds.
It is estimated that the school will emit about 15 tons less carbon dioxide each year
Regarding the detail of the energy consumption of the project of the CEIP Agustín Espinosa, the technical report determines a consumption of 35,535 kilowatt hours per year to supply the center, but the photovoltaic installation will be capable of generating 72,900 kilowatt hours per year. It is estimated that of the 35,535 consumption, some 29,160 kilowatts / hour can be used, especially due to timing issues. It is calculated that they will be poured as annual surplus to network about 43,740 kilowatt hours.
The photovoltaic installation, with a nominal 45 kilowatts, It is fed by three inverters of 15 kilowatts each. The development of this engineering project is based on a study of shadows that attends to the greatest number of production hours, which takes into account the differences in the incidence of the sun according to the time of year, as well as the precise inclination and orientation of the modules. or solar panels depending on the possible impact of shade from other buildings, which has estimated the weight supported by the roofs or which assesses the fact that a large part of the activity of the center is during the day and coincides with the productive hours of sun in those that are nurtured.
According Laura Lima, «The purpose of the project is to provide the school with a significant degree of energy self-sufficiency, thus reducing the consumption of fossil fuels and, furthermore, continue to comply with the local commitment to an energy policy respectful of the environment that is extended, depending on investment capacity and access to financing lines from different administrations, to other infrastructures ”.
