Accelerating the energy transition

One Solar is a leading Energy and Technology Partner in solar energy, electricity market and energy storage.

our goal

Solutions for making the energy transition

We work at both ends of the electrical and renewable energy sector, both with generators (large photovoltaic solar generation plants) and with large consumers (industry, services, administration), providing comprehensive services and benefits from one segment to the other.

We turn our clients into the real actors of the technological leap towards new business models, allowing them to lead the energy transition and to anticipate their competition

For a real energy transition

One Solar's commitments

Accelerating the energy transition

Our project is a commitment to contribute with our effort and knowledge in the process of Energy Transition. For OneSolar this process is the responsibility of the whole of society and we accept the challenge as specialists in the sector.

Access to clean energy

Our objective is to provide solutions and resources so that companies from different sectors can generate and/or access clean and free energy. We know that access to specialized knowledge and energy resources can be limited, so we are pleased to bring together the experience of our team and connect the different actors to ensure the viability of the projects.

Technological innovation

We are committed to technological excellence and innovation. We understand that this is the right way to achieve a change in the energy model as quickly as possible, which is not only sustainable but also economically profitable.

Integral partner

OneSolar does not aim to be a mere supplier, we work to be an integral partner and provide support for all electricity contracting and supply services. Our obsession is that our clients trust us and can focus on their business

Business Independence

We are committed to being independent of external interests, always prioritizing the optimization of energy consumption and an electricity supply based on renewable sources. OneSolar does not depend on large corporations, financial institutions or electricity marketers.

Local benefit

Based on the conviction that the energy transition is necessary and very positive for our society, we collaborate with the territory and local administrations to ensure that the projects we develop meet their specific needs and bring collective benefits.

Professional network

We prefer to work with partner companies that have been linked, like us, for years to the renewable energy and environmental sustainability sector.

Philosophy of commitment

At OneSolar we believe in what we do and enjoy doing it.
