1. EPC Company
Contractor
Design & Build 2x 5MWp Solar PV Project Land Area 40,000 SQM on Plot
Title 1 DPR Goa,Maharashtra

2. Project Team
• Project Director: TBA
• Project Manager: (TBC)
• Technical Manager: TBA
• Cost & Planning Engineer: (TBC)
• Sr. Technician(E & I): TBA
• Site Coordinator: TBA

3. Overview of Ground
Mounted PV Power
Plant
Basic Engineering + Design Schematics,
Configurations of Inverters, Technology
Selection shall conform to the best industry
practice. Access for HV/MV grid sub-station
shall be available for Switchgear/RMU +
Metering at MV level (by EPC sub-
contractor)​

4. Design Criterion
• The national grid code requires inverter to
provide reactive power control and hence shall be
over-sized.lly,THD shall be less than in the
inverter's AC power output.MTBF figures
availability must conform to industry standards.
String Inverters shall be preferred subject to site
conditions. Expanding the system capacity and
design flexibility shall be ensured. Shading
conditions, location of site inverters must be suited
to better IP class and cooling requirements are
mitigated to allow for permissible loss.
• Minimum requirements during design phase shall
be in following forms and formats:
• Datasheets of modules, inverters, array,mounting
system and other system components.
• Wiring diagram including as minimum as per Table
• Layout drawings showing the row spacing and
location of site information.
• Mounting structural drawings with structural
calculations ,reviewed and certified by a licensed
engineer.
• A detailed resource assessment and energy yield
prediction.
• A design report. It will include information on the
site location ,site characteristics, solar resource, a
summary of the geotechnical survey ,design work
and the energy yield prediction.

5. Data sheets for
Inverter
Type test certificates for inverters shall be
compliant to BIS and/or International
Standards. Module nameplate shall be
standard according to Table (Inverter
Specifications) standardized vide EN
50524:2009​

6. Single Line Diagram –
Grid Connected
Centralised PV System –
Electrical Works
A full independent due diligence is carried
out on the design before construction
commences.Therefore,'for Construction''
drawing(s) shall be approved by the design
review team or as deem fit.​

7. Annotated Wiring
Diagram Requirements
Cable Schedules for MV/LV Panels and
Earthing & Protection Schemes/Devices shall
be furnished by Gewis(OFS Subcontractor)​

12. Project Economics & Financial Modelling
Finance ,Returns, Debt Service
IRR >Weighted Average Cost of Capital(WACC)
IRR for the Equity Partner, if any The decision
rest with developer for implementation of
project based on equity IRR
NPV after discounting all present & future
receipts/outgoings >0 (+ve).
Picking discount rate shall be ascertained,
depending upon the uncertainty of receipts and
payments it is difficult.
DSCR=Cash flow available to service the
debt(/the debt service requirements(interest +
redemption payments based on long or short
term )
Sensitivity Analysis
• This analysis gives the lender and investors a
greater understanding of the effects of
changes in inputs such as power tariffs on the
project's profitability and bankability.
Therefore, typical results are monitored to
ascertain the key risks associated with the
project by changing PPAs single part tariff
fixed components(power tariff, capital cost,
and energy yield) which are listed as follows:
• Post Tax Project IRR
• Post Tax Equity IRR
• Average DCR
• Minimum DCR
