Nicolau Bussolotti Francine with the PlenoSol II solar cooker.

Pleno Sol was founded by Nicolau Bussolotti Francine in Brazil from the desire to generate income without jeopardizing future generations, have innovation as a principle, and incorporate a spirit of continuous improvement throughout its line of products, constantly seeking sustainable solutions.

Pleno Sol wishes to be recognized for excellence in the field of solar cooking and solar energy, with the commercialization of artisanal foods produced with solar energy, aimed at spreading the culture of solar cooking. Their goal is to improve solar cooker design, share information about solar cooking, and produce high quality food for sale. Pleno Sol operates as a commercial bakery offering various cakes and breads, as well as a manufacturer of solar cookers.

Hopefully, this approach will make the search for sustainable products and efficient equipment easier, and make using solar energy more affordable.
