Circular Solar Economy to boost the inclusive energy transition through the reuse of photovoltaic solar modules in needy local communities.

Long description

Currently in Brazil, 30% of the population receives monthly ⅓ of the minimum wage. On the other hand, solar energy grows exponentially, being the second largest source in the country. In this way, RESolis proposes a circular economic model that takes advantage of the solar module, which would otherwise be discarded, for reuse in needy communities, helping in a fair and social energy transition.

To validate the proposed model, it is necessary to apply a pilot, centralize information and provide training to educate stakeholders on current end-use options. From this, the pioneering project of Second Life of Solar Modules (RESolis) was born in the Photovoltaic laboratory of the Federal University of Santa Catarina (FV-UFSC).

The university has donated 76 units of modules that generated energy in an isolated system on the island of Ratones for the past 21 years. Now, these modules are being tested individually and, if technically approved, they will be reinstalled in needy communities. These communities will receive public lighting and monitoring cameras. Furthermore, the tests and results will be standardized for future use and the community will receive training to understand the technology, its benefits and proper disposal.

Seeking the expansion, after validating the pilot, a digital platform will be created, integrating stakeholders, allowing the offer of used modules to find communities and projects that demand this solution. The platform will also offer courses to qualify service providers in this circular model.
