Student, Faculty of Architecture, Islamic Azad University, Science and Research Branch of Hamedan Received: July24, 2015 Accepted: September 31, 2015 ABSTRACT The one of main human’s challenges is energy challenge. The way of exit of it, is going toward sustainable architecture. PV cells are one of the solutions that we have. One of important things in using pv cells is optimizing the using it’s products. This research is reaching to calculating and modeling of optimizing of light producing of residential units in Iran by PV cells. This research’s achievements are: calcuting the require lighting a common residential unit in Iran and how much it wants electricity and PV cells.

INTRODUCTION Moving to sustainable architecture is inevitable because of increasing the population, the consumerism and the problems in common energies caused by waste pollution. Since the underground sources of energy are consuming with a tremendous speed and nothing will be left in the near future, it is an obligation of the current generation to refer to the long-lasting energy sources. Nowadays people are focusing on the solar energy again after the events such as oil crisis, Chernobyl event and the greenhouse phenomenon[1]. The origin and persistence of human life is based on solar energy. Most of the basic activities and life-giving on earth such as photosynthesis and the water cycle will be done by solar energy. From the beginning of human history, man has recognized that proper using of solar energy would be suitable. However, only during the last 40 years the solar energy has been controlled by specialized tools and has been used as an alternative energy source. The main reasons for this choice is that this energy is free and do not damage the environment. These two reasons are the main factors of the sustainable architecture[7]. In the present age the solar energy can be used in many cases such as: Photo biological systems; changes in the life and life of plants and animals caused by sunlight like the process of animal manure decomposition and the use of their gas. Photochemical system; chemical changes due to the sunlight such as hydrogen supply installations. Heating and cooling systems; heaters, heating and cooling installations, desalination devices, greenhouses, driers and solar cookers. Photovoltaic systems; converting the solar energy into the electrical energy such as solar cells[1]. In Iran at least 5.5 kilowatt hours of solar energy radiate from the sun on every square meter of the earth surface and we have 300 sunny days in 90% of the country. The area of Iran is approximately 1600000 square kilometers. This means that the area of Iran is about 1.6 * 10 12 square meters. The solar daily radiation in Iran is 1.6 * 5.5 * 10 12 kWh. The total amount of solar radiation equals to 9000000000 megawatt hours. If we absorb the solar energy from 1% of Iran area and the efficiency of the receiving energy system is only 10%, we can receive 9000000 megawatts hour energy from the sun daily[2]. 2. MATERIALS AND METHODS 2.1.The application of solar energy in order to produce the residential lighting The solar lighting systems are divided into two main categories: The interior lighting including houses, workshops and …. The external lighting including street and parks lights, advertising panel lighting and …. The solar lighting system components include: 1-Solar Panels 2-Controller charge 3-Battery 4- Electronic ballast 472
