onsun - energy solutions

who we are

We represent investors active in this sector for the last 25 years. We intend to develop renewable energy production projects, through solar technology, taking advantage of the legal and regulatory opportunity offered to this sector.


We take advantage of the window of self-consumption and the increasing importance of decentralised production.

We offer the ESCO solution. It is a third party financing solution, offering customers, income or energy (in the self-consumption model).




We aim to develop decentralised production solutions. Preferably associated with ESCO models. Either by producing and selling energy to the RESP (Public Service Electricity Grid), or by developing self-consumption projects. The technological solution used is solar. It is based on solar module solutions – polycrystalline or flexible thin film – as well as on concentration solar technology solutions.
