“…La búsqueda necesaria para un futuro global más sostenible significa usar fuentes de energía renovables para generar electricidad libre de contaminantes, es así, las plantas CSP (energía solar concentrada) y fotovoltaica (fotovoltaica) son los sistemas más demandados para la producción de electricidad utilizando la radiación solar como fuente de energía (Alonso-Montesinos & Batlles, 2015). El diseño y la evaluación del rendimiento del sistema solar fotovoltaico y térmico requiere el conocimiento de la radiación solar global (Manju & Sandeep, 2019). La radiación solar y la temperatura ambiente son los recursos básicos para el despliegue a gran escala de tecnologías de energía solar (Dhimish & Mather, 2019).…”

En el Valle del Mantaro hay presencia significativa de la radiación solar, sin embargo, no están adecuadamente organizadas los datos que otorga las estaciones de la zona, es más, poseen una incertidumbre fuera de los límites permisibles por ser monitoreado con equipos obsoletos. Debido a que surgían investigaciones inherentes a las energías renovables, particularmente energía solar, había la necesidad de analizar y caracterizar los datos de radiación solar, a fin de que éstas sean los insumos para los diseños de sistemas solares, para tal efecto, se adquirió una estación actinométrica de alta precisión, en base a una selección y dimensionamiento adecuado, luego se instaló y se puso en operatividad, con este dispositivo se obtuvo 518 000 datos durante el periodo julio 2018 a junio 2019; los mismos que han sido tratadas con la asistencia del software Excel. La caracterización nos muestra que la radiación directa de onda corta en promedio anual es de 175,7 W/m2 y el máximo alcanzado fue de 553,3 W/m2, generando una variación de 151,7 W/m2 y 410,3 W/m2, respectivamente. La radiación difusa de onda corta fue de 98,2 W/m2 en promedio anual y alcanzó como máximo 297,3 W/m2, con una desviación estándar de 52,7 W/m2 y 170,1 W/m2.

The sun is the primary source of life on the earth. The heating effect of the sun provides a more fruitful environment for mankind. In addition, solar energy in the form of thermal radiation has been utilized for solar thermal applications and space heating. With abundant solar radiation, the emergence of the solar desalination has been emerged as a viable solution for water purification by utilizing solar stills. However, solar-powered distillation is relatively a slow process due to the requirement of bulk heating. To suppress thermal conduction to bulk water, various photothermal materials were employed. However, there are many governing parameters which influence the productivity, including solar intensity, cloud, wind, ambient air temperature, humidity, solar absorption of blackened surface, depth of bulk water, feed water type, angle of condensation surface, water film thickness, underneath the condensing surface, and experiment period. Further, systematic and continuous experiments for extended periods are essential for determining the stability and durability of a solar desalination system. The main objective of this article is to review all the experimental studies conducted for two months at minimum up to 1-year duration. In addition, all the SDSs handled in this study further were examined by solar geometrical factors, including day length (DL) and position of the sun or zenith angle (θ z ). As a result, the sunshine hours, day length, and the solar zenith angle play an important role in the water evaporation rate. Lower solar zenith angle and longer day length (more sunshine hours) are desirable for higher water productivity.

“…Karakoti et al [9] shows that all the models performed fairly well to estimate the mean monthly solar global irradiance for twentythree different stations in India. Recording the dust, cloud cover, aerosols and scattering of rays from the atmosphere [8] and also temperature and relative humidity [9] pose strong difficulties in estimation of solar radiation. The amount of solar radiation harnessed by any panel is depended on the absorption and orientation (tilt) of the panels.…”

Solar panels can achieve the highest yield when they are oriented in the right way as the influence of the tilt angles can lead to a high impact on the performance. This paper demonstrates the effect of the tilt angle on the final yield and maximum utilization of solar energy. The annual optimal tilt angle of the solar panels for Pune was found out using the Liu and Jordan model. The optimal tilts yielding an increase of 7% was found out to be 0° on the months starting from April and lasting till September and 40° starting from October and holding at 40° till March. By changing the tilt angle every month, there was an increase in the yield by more than 8%. For better yield and maximum utilization of solar energy, optimizing the tilt angles of solar panels monthly or even twice a year is effective based on the study. Most of the panels are fixed at an angle equal to the latitude of the place and oriented towards the Southern sky in the northern hemisphere. Measurements of the monthly average global solar radiation, monthly average temperatures, and monthly average relative humidity were compared. Further ahead regression correlation for a linear model was carried and the regression coefficients a and b were found out to be 0.2804 and 0.3618 respectively.
