These deaths and illnesses can be significantly reduced by using very efficient, reliable, safe and economical solar cookers with which any type of food could be cooked most of the days of the year. Even thought there are today lots of succesfull designs of solar cookers, we still need such optimised designs that could operate even in frankly cloudy days;the solar cookers presented here meet these strict requirements. Globally, cooking food involves a significant and unavoidable consumption of energy cause more than 7.8 billion people must eat at least three times a day and this cooking is done mostly by burning fossil fuels or firewood, generating a large amount of toxic and greenhouse gases and particles that are very harmful to health and the environment. The massive use of solar cookers would have great benefits, but to guarantee their use for at least 85% of the days of each year it is necessary to have very high-performance solar cookers, keeping ease use and reasonably low manufacturing costs. The use of Nonimaging Optics and the Constructal Design have made possible to create solar cookers with which them is possible to cook any food on almost any day of the year. Details of their design and some operational results are sumarised here. © 2021.

Solar thermal applications are indispensable and crucial technologies with increasing attention in renewable energy research for their high energy conversion efficiency and energy storage density. Solar collectors can absorb nearly the entire solar spectrum; around 50% of the sun's energy is invisible to the human eye in the infrared spectrum, as heat. Thermal energy storage (TES) can store on average around 10, 000 kW for about 6 hours. Financially, solar thermal energy conversion systems in many locations have reached gridparity (EUR 0.02 0.05/kWh for low-temperature and EUR 0.05 0.15/kWh for medium-temperature applications). Thus, solar heating and cooling (SHC) systems are identified as typical application areas for the huge technical potential of solar thermal integration (up to 5.6EJ in 2050) available within industries that are predominantly being met with environmentally unfriendly and less available fossil fuels. The scope of this review is, therefore, to demonstrate the state-of-the-art for basic energy generation and supply concepts of solar thermal systems for industrial application. The paper presents the basic solar thermal system design, configuration, operation, and possible integration concepts with an existing conventional system. It also describes the techno-economic mathematical models and analysis techniques for solar thermal system key performance indicators. Accordingly, this paper can be used as a brief extract and guide to systematically approach industrial solar system development projects using best practices adopted to explore the contributions of the researchers in the literature.","PeriodicalId":216647,"journal":{"name":"Proceedings of the SOLAR 2021 Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116736189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how best to configure the geometry of these bifacial solar collectors is non-trivial as many geometric factors (tilt, ground reflectance (albedo), height above ground, row spacing, module spacing) tend to be interdependent, requiring a case by case analysis in order to optimize the total power output and maintain the frontside incident irradiance while maximizing the backside gain. In addition, as with monofacial modules, use of planar reflectors can be a cost effective way of increasing the incident irradiance, in the case of bifacial modules, on both sides of the module. However, the addition of reflectors adds to the challenge of optimizing the system configuration. The work described here presents an experimental and modeling study of reflector enhanced bifacial modules. Experiments were conducted on bifacial modules with and without reflector augmentation and compared against monofacial PV modules, assessing the effects of specular and diffuse reflectors. A model was developed to calculate the incident and reflected irradiance on the front and back sides of the modules. Beam insolation components were handled with ray tracing and sky and reflected diffuse components were handled with view factors.","PeriodicalId":216647,"journal":{"name":"Proceedings of the SOLAR 2021 Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129636446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
