Freelancer profile translated to English.

Description

I help engineering companies, installers, and developers outsource the design of photovoltaic plants through precise, execution-ready technical studies.

I specialize in modeling and simulating PV systems using PVsyst, developing optimized designs for both grid-connected and off-grid systems. I deliver comprehensive analyses that validate energy production, system losses, and project feasibility before construction.

My focus is on generating clear, reliable technical documentation aligned with international standards, facilitating decision-making and reducing risks in the design phase.

I work on projects such as:

Energy simulation of PV plants in PVsyst

Production calculation (Yield, PR, losses)

Configuration optimization (orientation, tilt, strings)

Shading analysis and system losses

Technical feasibility studies for solar projects

Technical support for engineering teams (design outsourcing)

Additionally, I have experience in the coordination and management of energy projects, working with multidisciplinary teams in different countries. This includes technical follow-up, communication with clients and suppliers, and ensuring projects progress according to scope, timelines, and defined objectives.
