The first version of the Prosumidor Guide, launched in 2019, was an effort to raise awareness and popularize the economic and environmental benefits of solar energy production, by providing all those interested with useful information on how to become prosumers. Since then, the situation has evolved, the number of prosumers has reached around 120,000, and the trend is set to continue.

In this promising context for the development of solar energy, the need has arisen to support prosumers in becoming even more sustainable by adopting behaviors and energy solutions that help them make the most of the energy they produce.

Thus, the Sustainable Prosumer Guide presents a set of useful recommendations for those who are already prosumers to become (even more) sustainable. In addition to reviewing the steps to become a prosumer, the Guide provides useful information from prosumers and examples of best practices to maximize the return on investment in self-produced energy systems, offers recommendations on the choice and sizing of equipment and ways to increase self-consumption, and last but not least, clarifies the billing of prosumers. All this promotes best practice and projecting this reality into the future by developing sustainable energy communities.
