Executive Summary
PROJECT COORDINATOR Dr. Nadja Adamovic Technische Universität Wien Phone: +43 1 58801 76648 Fax: +43 1 58801 36698 E‐mail: [email protected] SME‐Targeted Collaborative Project FP7‐NMP‐2012‐SME‐6 http://www.solar‐design.eu/ Grant Agreement No. 310220 Duration: Jan. 2013‐ Dec. 2015 Executive Summary The vision to use photovoltaics (PV) as a decentralized and sustainable source of energy in their products is shared by thousands of designers, architects and manufacturers world‐wide. In principle PV can be integrated directly in products, such as devices, vehicles and buildings. Nowadays the development of photovoltaic modules is still primarily driven by the idea of economies of scales which leads to unvaried PV modules that are only good for large‐area installations. These photovoltaic modules are not suitable for the integration into building skins, roof tiles or electric devices because of their rigidness and their electrical constraints. Even companies which could provide a solution for these applications (flexible thin‐film PV firms) are not providing customized PV modules because of the associated set‐up times. The SolarDesign project addresses these obstacles by the development of novel solar cell materials, manufacturing processes and supportive actions to improve communication in the design value chain. One key technology is a novel monolithic interconnection process for thin‐ film solar cells that simplify the production of thin‐film modules and allows adjusting the essential properties of a PV module “on‐the‐fly” without excessive set‐up times. It allows adjusting the electrical properties of a given PV module on the fly as well as the production of fully customized photovoltaic modules in respect to size, shape and patterns. -

Solar Energy - Wikipedia, the Free Encyclopedia
Solar energy - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Solar_energy From Wikipedia, the free encyclopedia Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces.[1] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar Nellis Solar Power Plant in the United States, one of techniques include orienting a building to the Sun, selecting the largest photovoltaic power plants in North materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. America. In 2011, the International Energy Agency said that "the development of affordable, Renewable energy inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise.

Energy Saving Control of Solar LED Street Lamp Based on Microcontrollers
Advances in Engineering Research, volume 166 3rd International Conference on Automation, Mechanical Control and Computational Engineering (AMCCE 2018) Energy Saving Control of Solar LED Street Lamp Based on Microcontrollers Wang Fei Nanchang Institute of Science and Technology, Nanchang, China, 330108 Keywords: microcontroller, solar energy, LED street lamp, energy-saving control Abstract: In the modern society, the idea of energy saving and emission reduction has gradually permeated people’s production and life. In order to achieve this goal, all links in all industries should focus on the implementation of energy saving control. And specifically, the solar LED street lamp based on microcontroller is particularly important. The proposal of the design idea is of great practical significance to the undertakings of environmental protection. In this process, the characteristic analysis on LED light source is a prerequisite. Based on this, an intelligent street lamp driven system based on microcontroller is devised in the paper. Then, it discusses the work process in detail, and finally, works out a controlling methods of LED street lamp suitable to actual circumstances. Operating temperature and external light, for instance, are influencing factors. Only by putting the above requirements into place, can the advantages as well as social value of LED street lamp illuminating system can be fully demonstrated and utilized, injecting a steady stream of driving forces into the environmental protection of China. Compared with traditional lightings, white LED is energy-saving and environment friendly with a relatively long service life. In general, it is a practical and efficient electro-optical light source, which is listed as a major emission reduction measure by the Chinese government. -
Clean and Green Technology : Hybrid Solar Lighting
Clean and Green Technology ‘Hybrid Solar Lighting’ Abstract— We demonstrate an innovative application and turned off during the day, which results in lower electricity investigative results of fiber optic day lighting systems as a bills and less energy demand. means of bringing direct sunlight into a building while maintaining the controllability and ease of application usually reserved for electric lighting by collecting natural light and channeling it through optical fibers to luminaries within the space. In contrast to conventional methods of lighting as well as solar energy, this project focuses on reducing losses due to radiation, transmission and conversion to achieve increased efficiency and provide a profitable solution to the energy crisis the world is facing today. This project manifests the system performance which is accurately described by employing and analysis based on fiber and lens optics and interior illumination. Excellent efficiency is achieved which is only slightly reduced due to either transmission losses, although negligible, or a cloudy day, by employing the concept of hybridizing solar source along with electrical source for optimum interior lighting. This is implemented by using high quality Fresnel lenses (for concentrating and collecting sunlight), optical fibers (for transmission) and luminaries (for lighting). Large scale commercial buildings such as textile showrooms, malls, hospitals, museums, schools, colleges are the major nerve centers of applicability of this project. For Figure 1: Principle of HSL employing simple yet innovative principle, elementary mechanical concepts were executed with the sole purpose of curbing pollution, to dwindle green house effect and tackle energy crises. The high efficiency ingenious applicability III. MATERIALS REQUIRED achieved in this project brings it one step closer to commercialization. -
