This research investigates whether the installation of photovoltaic solar power plants in Brazilian beef cattle farms presents strategic advantages when compared to those in which there is no other form of interaction with the generating units. For this, it is proposed the adhesion of standard solar roofing, as well as stalls, which are sized to accommodate up to 100 adult cattle and are capable of capturing rainwater along with part of the animal waste. It is estimated that one-third of the bovine waste can be collected to be later used as means of biogas and biofertilizers generation. Biogas allows more energy production and biofertilizers can be used for the animals’ feed planting, which will thus reduce monetary costs and environmental impacts. Shading for beef cattle is one of the requirements of the Humane Farm Animal Care certification, which is the world's largest production animals welfare certification. In order to obtain this certificate it is also necessary to fulfill other prerequisites. Shading, however, is a difficult item to be attended by large-scale beef cattle producers. With the energy availability provided by the adhesion of the proposed model, it is identified the opportunity to station slaughterhouses near cattle creation sites, which allows slaughtering and processing to be performed as a social business. Such geographical proximity will also ease the attendance of another major aspect of the welfare certification, the caution with the animals transportation to the slaughter location. Clear strategic advantages, which excel the drawbacks, were identified. If all Brazilian beef cattle production adhered to the proposed integration model, it would be possible to obtain around 160 TWh per year with the solar roofing, in addition to more than 12 TWh per year with the biodigesters. Based on the Brazilian Electricity Regulatory Agency - BERA’s (Agência Nacional de Energia Elétrica - ANEEL) figures, these numbers are equivalent to an annual revenue of R$ 47 billions and R$ 2 billions (US$ 14.71 billions and US$ 625.7 millions), respectively. The proposed model also enables the capturing of more than 120 billion liters of water per year, to be used in cattle breeding and biodigesters dilution. This will later grant the fulfillment of one of the requirements for animal welfare certification, arising then the possibility to add more monetary value to the Brazilian meat.
