“…In our study area, located in Portoviejo, the environmental impact is given by the imports of the panels, equipment, and accessories of the photovoltaic systems to be installed and the transfer to the region of location the same [33]. The province of Manabí is located in a humid and very hot climatic zone according to the zoning of the Ecuadorian Construction Standard (NEC) [34].…”

<span lang="EN-US">The research analyzes the influence of the average temperature on the performance of specific photovoltaic solar modules under the environmental conditions of the city of Portoviejo, province of Manabí, Ecuador. The research is carried out using the qualitative methodology. Its main objective is to determine the influence of temperature on the energy performance of photovoltaic modules under the region's environmental conditions. Two electrical diagrams with different configurations were designed, which were analyzed and simulated using the MATLAB Simulink software. The results obtained show the direct relationship between the electrical parameters of voltage, current intensity, and power with the temperature value on the surface of the modules. It is concluded that the modules generate a higher value of voltage, electric current intensity, and electric power at a lower temperature, regardless of the level of solar irradiation they receive.</span>

“…Potential alternatives and proposals for reducing energy consumption from lighting in buildings have been developed, utilizing more efficient technologies and renewable energy sources. Among these suggestions related to energy efficiency are improving the quality of luminaries in energy efficiency and lighting modeling before the construction of buildings [21]. Improving the quality of luminaires, such as implementing LEDs, can reduce energy consumption by approximately 50% compared to fluorescent lighting [22].…”

“…According to studies, providing minimal light and electric power to surgical equipment might cut maternal mortality by 70% [24]. The main suggestion related to renewable energies is integrating renewable energy in buildings [21]. Integrating renewable energy is essential for the building sector, since in places like Europe, this sector represents 40-45% of the total energy consumption [25].…”

Developing and underdeveloped countries face innumerable problems related to the accessibility and quality of energy that put the lives of patients, health-care infrastructures, and health workers at risk. Current approaches, such as grid power, unsustainable energy sources such as diesel or gas, and mobile health clinics, have proven insufficient to address this issue. In response, access to reliable health care and electricity has undergone multiple transformations in the last decade, especially in remote and rural areas. Good health and clean energy are two of the 17 United Nations Sustainable Development Goals, originally designed to be a “shared blueprint for peace and prosperity for people and the planet, now and into the future.” Unfortunately, little is known about the interaction between health-care access and energy access in developing and underdeveloped countries, mainly in remote or rural areas. For this reason, this study conducts a review of the literature, including current approaches, challenges, and opportunities for the implementation of solar energy in health centers. As a result, several challenges and opportunities in three impact areas are presented: (1) operational, (2) environmental, and (3) economic. This study delivers detailed information that allows the implementation of solar energy in the health-care sector (in a more effective manner) by sharing best practices.

“…Then, with these measurements we determined the luminous efficacy (η) (expressed in lm W −1 ) using Equation (1). The minimum illumination level (Ev) was calculated dividing the value of Φ by the surface (S) (1.2 m 2 ) (expressed in lx) and the limit value of energy efficiency (VEEI) (expressed in W m −2 ) was then calculated using Equation (2) following the methodology established by Hidalgo et al [20].…”

Nowadays, the evaluation of sustainability is an important aspect in the study of agricultural systems and the number of projects and methods for impact assessment of food production systems is increasing. In this work, we initially carried out a survey to know the status of the artificial lighting establishment in horticultural seedling nurseries in southern Spain. Taking into account the data obtained in the survey, we conducted an experiment with different types of fluorescent lamps (TLD-18, CF, TL5, TLD-56), light-emitting diodes (LEDs) and their combinations along with the novelty white LEDs lamps and XTRASUN LEDs to evaluate their technical parameters and spectral light qualities. In addition, the effectiveness of light irradiance (ELIplant) and the use of irradiance (UI) by cucumber and tomato seedling plants were estimated considering their light absorbance capacity previously analyzed. The results showed that TLD-18 lamps and their combinations, CF and XTRASUN LEDs, had a limited value of energy efficiency (VEEI) ≤ 2. The lamps essayed with the lowest total irradiance were LEDs (B, R, V, W) and the ones with the highest values were TLD58-6 lamps. The effectiveness of light irradiance (ELIplant) and the UI were slightly higher in the case of cucumber than that of the tomato for all essayed lamps. Considering the effectiveness of the light irradiance (ELIplant), TL5-6 lamps showed the highest values. On the other hand, considering the use of irradiance, XTRASUN LEDs on the mode of vegetative growth (VG) showed the highest values.
