Who We Are?

about us

S4 Solar do Brasil, is a Brazilian company based in Pernambuco, is engaged in sustainability, research and development of new technologies for energy generation electricity through photovoltaic panels, in addition to seeking improvement in the structure with the use of inputs, strengthening the national industry. Over these years, S4 Solar do Brasil has developed projects and studies to implementation of solar energy in Brazil, and also established partnerships with the largest companies with know-how in the manufacture of equipment and materials, such as photovoltaic panels, inputs, industrial parks, batteries for energy storage, engineering companies for the assembly of solar plants and transmission lines, among others.

Our company understands the importance of the participation of great professionals in any success story. Among the great partnerships sealed, S4 Solar do Brasil highlights the participation of world-renowned scientists and consultants, references in the sector, are post-docs in solar cell and developers of technologies used by companies like Boeing, NASA, and others. In this sense, the technical board of directors.

The Doctor. Frank Faller, from our first 100% automated photovoltaic panel factory in America, bringing the best in the manufacture of photovoltaic modules and solar cells.



Frank is a veteran of the solar PV industry with over 25 years of experience in research, manufacturing, sales, business development and management across the entire PHOTO VOLTAIC value chain, including crystalline silicon wafer., solar cell and PV module technology, starting with industry pioneers like Astropower and Shell Solar.


Training as a solid state physicist and Ph.D. in materials science on photovoltaic silicon provides a very solid foundation for this work. Stefen starts in 1996 at the Fraunhofer Institute for Solar Energy Systems ISE doing a doctoral thesis on silicon materials for photovoltaics. Thereafter, in various scientific and leadership roles in photovoltaic R&D

Ben spent his career in solar energy. His innovations had global reach through his work on early solar pioneers, Suniva and SolarWorld. 
He has worked around the world commercializing new solar technologies and building solar energy manufacturing facilities. Ben received his PhD in Electrical Engineering from Georgia Tech and did some of his work at the Fraunhofer Institute in Germany.
