Throughout 2014 and 2015, a project called “50 Telhados” (50 Roofs in Portuguese) has been an initiative of the Instituto Ideal for installing fifty 2 kWp or 100 kWp total power photovoltaic systems per included city, has resulted on the installation of 369 PV roofs in Brazil. This project has been conducted in partnership with PV installing companies in 22 cities in Brazil and has amounted to approximately 2.38 MWp installed power with an estimated 3.62 GWh generation per year. President of Ideal`s Institute, Mauro Passos, believes that this project has encouraged a suitable competition, producing results that confirm the widespread use of PV technology, urban by definition. “50 Telhados has been a tool that can leverage and aid consumer decision-making.”
Of the 22 included cities on the project, nine (9) have achieved their intended target, and, most of them, through total installed capacity. Fortaleza (CE) and Rio de Janeiro (RJ) have effectively installed more than 50 roofs. Other cities that have achieved their goals were: Florianópolis (SC), Salvador (BA), Santa Cruz do Sul (RS), Campo Grande (MS), Curitiba (PR), Luis Eduardo Magalhaes (BA) and Recife (PE). The three states with the largest number of installed roofs were Ceará, Rio de Janeiro and Rio Grande do Sul, each reaching more than 60 PV installations. In terms of installed capacity, in addition to these three states, Bahia deserves to be highlighted, it reached second place, followed by Ceará.
The 50 Telhados Project has been locally implemented in those cities by 15 installing companies. Of these companies, the ones able to amount the largest number of cities were Solar Energy do Brasil, which has amounted five cities from different states; and Enersol Brasil, with four cities in the state of Bahia. Satrix has accounted for the largest number of PV installations in a single city, 63 solar roofs in Fortaleza. Solar Energy do Brazil came next (37 in Campo Grande and 33 in Rio de Janeiro), followed by Solled Eficiência Energética (28 in Santa Cruz do Sul) and Araxá Energia Solar (22 in Florianópolis).
The 50 Telhados Project was developed by Instituto Ideal in December 2013, with the aim to broadcast photovoltaic distributed generation, thus promoting REN 482/2012 – Regulating Norm of the Brazilian Electric Energy Agency (ANEEL), which creates net metering. The target of reaching 50 photovoltaic roofs of 2 kWp or 100 kWp of total installed capacity per city could be reached individually by the installing company or joined by others, in a period of up to two years.
The German Cooperation for Sustainable Development has supported this project through Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH.
