Solar PV Technical
Due Diligence & Advisory
KRD Renewables provides independent Solar PV technical due diligence for investors, lenders and developers across Poland and Central and Eastern Europe. We assess project maturity, PV technology, module and inverter selection, project design, energy yield, grid connection, permitting, contracts and other technical risks to support informed acquisition, financing and investment decisions.
KRD’s Solar PV technical due diligence provides an independent assessment of the technical, development and performance risks that may affect a project’s value, bankability, delivery or long-term operation.
The review can cover project documentation, permitting, land and grid arrangements, PV technology and design, module and inverter selection, mounting systems, energy yield, performance assumptions, project contracts and technical assumptions within the financial model.
For utility-scale Solar PV projects, KRD’s TDD service can be structured in two independent phases, which may be contracted separately or sequentially depending on the transaction and the level of review required.
Solar PV Technical Due Diligence
PHASE 1 - RED FLAG ANALYSIS
Typical Scope Includes:
Screening of PV designs, equipment documentation and energy yield studies available in the VDR
Identification of material risks in PV yield, module and inverter selection, mounting, permitting, land rights and grid export
Review of environmental decision and zoning status
Land lease structure and plot consistency check
Review of grid connection and agreement status
High-level assessment of project layout maturity and installed capacity, including MWp / MWac
Headline review of energy yield assumptions where available
Identification of missing information and administrative gaps
Deliverable:
Concise Red Flag Memo with structured risk classification (None / Minor / Medium / High), highlighting material risks, information gaps and mitigation considerations
PHASE 2 - FULL TECHNICAL DUE DILIGENCE
Typical Scope Includes:
In-depth review of issued permits, licences and compliance status
Review of outstanding permits and realistic permitting timelines to COD
Grid interconnection and contractual review, including review of connection conditions, grid agreement and technical obligations
Consistency check between permits, land title, project layout and grid capacity
PV technology and design assessment, including DC/AC ratio, modules and inverters, equipment degradation, mounting systems and geotechnical assumptions
Review of installed capacity, maximum export/import capacity and key grid parameters, including MWp / MWac
Review of P50/P90 yield, shading, electrical losses, availability, degradation and curtailment assumptions
High-level review of CAPEX and OPEX assumptions from a technical perspective
Review of key project contracts from a technical perspective, where available, including EPC, BoP, supply and O&M documentation
Identification of key technical, grid and permitting constraints affecting value or schedule
Identification of key project risks, mitigation measures and residual exposures
Deliverable:
Full TDD report supporting acquisition or investment decisions, incorporating Client comments
Due Diligence Focus Areas
01
PV Technology Assessment
PV technology assessment tests whether equipment selection, system configuration and design assumptions are consistent with the wider project. KRD reviews the proposed technology against available project documentation and operating assumptions.
Focus areas
- Module and inverter selection
- DC / AC ratio and system architecture
- Mounting-system and electrical interfaces
- Degradation and site assumptions
- Equipment specifications and technical documentation
02
Module, Inverter & Balance-of-System Review
KRD reviews the principal equipment and balance-of-system elements that underpin Solar PV project performance. The assessment considers whether the proposed equipment, supporting infrastructure and technical interfaces are consistent with the project design.
Focus areas
- PV module specifications and degradation
- Inverter selection and configuration
- Mounting systems
- Civil and electrical infrastructure
- EPC, BoP, supply and O&M responsibilities
03
Technical Due Diligence for Investors & Lenders
Solar PV technical due diligence provides investors and lenders with an independent view of the assumptions and risks underlying an acquisition or financing decision. KRD assesses the technical project information alongside development, contractual and performance assumptions.
Focus areas
- Project technology and design
- P50 / P90 yield and performance assumptions
- Grid connection and export limitations
- Permitting, land and site constraints
- Technical issues affecting bankability
04
Project Design, Performance & Technical Risk
Solar PV project value depends on the interaction between technology, design, site conditions, energy yield and contractual arrangements. KRD focuses on issues that could materially affect project performance, delivery or long-term operation.
Focus areas
- Layout, capacity and DC / AC design
- Energy yield, losses and availability
- Grid connection and curtailment
- Permitting and land constraints
- Technical contracts and project interfaces
Optional Scope of Work
