The world seeks new forms to mitigate the dependence of fossil fuels and emissions of effect gases greenhouse. The climatic changes and the possible scarcity of the oil force the search for new forms of energy generation. The solar energy, object of this work, is one of the sources of energy generation in constant expansion, according to the Global Market Outlook for Solar 2016-2020 report. Each country, including Brazil, must by means of iNDC (intended Nationally Determined Contribution) define the policies to be adopted to reduce and to remove the emissions of gases greenhouse (GHG), contributing for the Paris agreement. According to the Brazilian Atlas of Solar Energy (INPE, 2017), although Brazil to possess index of superior solar irradiation to the found ones in the majority of the European countries, it is a power plant little explored, currently in the electrical matrix corresponds only the 0.93 GW, which corresponds, 0.59 percent of all electrical matrix (ANEEL, 2018), but its projection for 2024 indicates to a growth of 7 GW, around 3.3 percent (EPE, 2015b) of all the electrical matrix. Brazil tends to become more competitive in the solar market, since there is the attempt to purify the silicon, here in Brazil, at UNICAMP, that is, avoiding to export raw materials to import after the silicon purified. Parallel to the growth of photovoltaic energy, Brazil has the MCMV program that aims to facilitate the access to the property of the less wealthy classes of society, the program has since delivered more than 2.5 million homes and estimates the hiring of more two million. The program does not aim at the rational use of the matrix, it is mainly concerned with the issue of housing shortages in the country. Despite, it is glimpsed possibility to include in its target a program of generation of clean energy for the layers most devoid of the society. This could create a program of popular dwelling with environmentally sustainable lines of direction. Probably, one of the reasons for not including issues related to the generation of clean energy in the Minha Casa Minha Vida dwellings is the usual thinking that such an element could excessively burden the construction costs, and may even increasing the costs of access to housing and maybe distort the program. Although housing may have its costs increased at an early stage, it should not be overlooked that such initial costs may be ignored in the long term by the economy derived from the use of solar energy, in addition to estimating the impact of that generation on the expansion of the Brazilian electric system.
