Technical Due Diligence

Technical Due Diligence (TDD) at LuciSun is an independent and structured technical assessment performed in the context of project financing, acquisition, or major contractual decisions.

Its purpose is to determine whether a photovoltaic project is technically robust, internally consistent, and aligned with realistic performance expectations, while identifying material technical risks, inconsistencies, and sources of uncertainty that may affect the long-term value and operability of the asset.

This assessment provides investors, lenders, and project owners with a clear and traceable technical basis for informed decision-making.

The assessment is based on a structured analysis of the project’s technical and regulatory documentation and typically covers: 

  • EPC and O&M contract reviews from a technical scope and performance perspective 
  • Construction quality assessment and site visits, depending on the project phase
  • Environmental permitting and regulatory constraints 
  • Grid connection conditions and technical interfaces
  • Desktop analysis of the site and its constraints
  • System design, layout, and component selection
  • PV components quality assessment
  • Solar Resource Assessment, PV Energy Yield Assessment, and, where applicable, PV Performance Assessment, whether carried out by LuciSun or reviewed on behalf of the client

Most of these topics are analysed directly by the LuciSun team, drawing on internal expertise in photovoltaic system design, modelling, data analysis, and operational performance. For aspects with a strong local or regulatory component, such as environmental permitting or grid connection conditions, the analysis is performed in collaboration with local experts familiar with the applicable regulatory frameworks and technical practices. This approach ensures that conclusions remain technically sound while being fully adapted to the local context of each project.

A key element of the Technical Due Diligence is the verification of consistency across the various project documents and technical studies. The objective is not to reproduce underlying analyses, but to ensure that assumptions, inputs, and uncertainty treatment are coherent across the documentation and appropriate for the specific project context.

The outcome of the Technical Due Diligence is a consolidated technical position on the project, highlighting material risks, residual uncertainties, and elements requiring mitigation or clarification. This technical view provides a clear and traceable basis for investment, financing, or contractual decisions.
