Sitawi develops solar energy simulator

Free tool allows energy consumers to test the economic viability of installing solar panels

Solar energy, in addition to being clean, has become increasingly competitive with other sources, especially when used as distributed microgeneration. In this model, energy consumers, which can be homes as well as commercial and industrial enterprises, install solar panels with up to 1 MW of capacity on their roofs, becoming energy producers.

However, many variables can influence the economic viability of this energy, such as equipment cost, volume and time of consumption, taxation and the price of electricity sold by distributors, which vary from state to state. The tool developed by Sitawi allows energy consumers from any Brazilian state to test this economic viability using simple and available data on their own consumption.

The Simulator was developed at the end of 2014 at the request of the Ethos Institute, which led the project ?Sustainable Business: Transforming Ideas into Innovative Models?, whose objective was to demonstrate the viability and competitive advantage of sustainable business in Brazil. Throughout 2014, the project held five meetings in which methodologies such as design thinking, Business Model Canvas, financial modeling among others. The group made up of nine large companies, specialists in finance, sustainability and design chose to work on the modeling of distributed photovoltaic solar microgeneration for companies of different sizes and energy contracting models.

Sitawi Financeira do Bem was responsible for the methodology and facilitation of the meetings and for the production of the Simulator.
