4. Due Diligence by Lender
Legal due diligence – assessing the permits and contracts (EPC and
O&M).
Insurance due diligence – assessing the adequacy of the insurance
policies and gaps in cover.
Technical due diligence – assessing the technology, integration and
technical aspects of the permits and contracts.

5. Typical areas for Technical Due diligence
Sizing of the PV plant:
Layout in the land area available.
Appropriate buffer zone around the plant t
account for shading/other activities.
Overall size appropriate for the grid connection.
Layout of the PV modules, mounting and/or trackers, and inverters:
Assessment of level of inter-row shading.
Access to plant components for maintenance and installation activities.
Electrical design layout and sizing:
Assessment of cable losses in the DC/AC cabling.
Assessment of appropriateness of the cable placement and connectors.
Appropriateness of the earthing and protection systems.
Compliance to safety standards.

6. Typical areas for Technical Due diligence
Technology review of major components (modules/ inverters/mounting or
trackers):
Suitable for environment.
Integration of components.
Track record of suppliers and models.
Quality and compliance certificates.
Compliance to safety standards.
Warranties.
Design life.
Degradation assumptions.

7. Typical areas for Technical Due diligence
Energy yield assessments:
Appropriateness of any assumptions made.
Source of solar irradiation data.
Assessment of shade.
Degradation assumptions.
Uncertainty analysis.
Model used and modelling techniques.
Check the theoretical Performance Ratio.

8. Typical areas for Technical Due diligence
Contract assessments (EPC, O&M, grid connection, power
purchase and FiT regulations):
Looking for interface points and areas where there could be
risks.
Examining construction timelines and ensuring that the
critical path is clearly identified and mitigated in the contracts.
Assessing the warranty and guarantee positions within the
contracts – protection for the lenders.
Financial model assumptions:
Assessing that the assumptions used are complete and
appropriate
