Proposal the Use of Alternative Materials for Construction of an Alternative Low Cost Sunlight Collecting System to Latin American Market

This paper presents a study on the potential use of fixed collectors consist of prismatic lenses that capture sunlight for indoor lighting. The proposed research is to develop an alternative system to capture sunlight, aimed at lighting environments with natural light directly, maintaining thermal comfort without cost functional, using a source of clean and inexhaustible energy. Currently the technology to capture the natural light is not developed in Latin American, but is already exploited in other countries so quite efficiently reaching present yield greater than 90% transmission of natural light due to its high quality finish. This market the application of this technology is in quite small considering the high cost of implementation for point light added to the import taxes can reach US$ 1,500.00 (in Brazil). The main focus of the work is to develop a product that through the study and development of materials from raw materials derived from municipal solid waste can provide a low cost solution with adequate income to reality where the product is applied. The work requires the design of a prototype of the capture system using the materials developed and the validation of the same real situation of application for a period of twelve months so predicting system behaviour verification in various conditions and to verify the behaviour materials developed front inclement weather and aging. As a result of this preliminary study it was found that the costs of materials to be used for the development of alternative products do not reach even 20% of the current selling price. Therefore, the development and industrialization of this low-cost sunlight collecting system result in a social nature of technology accessible to all. Consequently, will benefit dealers, who can distribute it poor communities, improving the quality of life of these people and thus reduce non-technical losses. Therefore, with the focus in the popularization of technology in Latin American, presenting this as a low cost solution, the work aims to develop an alternative to natural light harvest, using recycled and reused materials, making it an environmentally friendly product, good efficiency and sustainable.
