This document outlines the key steps and considerations for project management of a solar power plant, including: 1) Conducting site analysis and basic engineering to evaluate location feasibility. 2) Developing a feasibility report, financial plan, and plant design. 3) Overseeing construction, ensuring quality, and addressing potential delays. 4) Commissioning the project by testing functionality and connecting to the power grid. 5) Establishing operation and maintenance procedures for ongoing plant upkeep.

Concentrated PV, Tracking, etc.) on the following parameters:
 Current & future expected capital costs , Efficiencies (including sensitivity
to ambient temperature)
 Performance of Solar Plants using the proposed technology, Operation &
Maintenance Practices

 Detailed budget with costs for the Project
 Identify and define key parameters and assumptions for the cash flow
 Prepare detailed financial models for the Project to forecast the:
 Internal Rate of Return
 Net Present Value
 Debt Service Coverage Ratio (DSCR)
 Sensitivity analysis on various costs, interest rate, and other parameters
as required.

11. Construction delays
 Design flaws. Poor design of components, such as the support
structures, lead to costly and time-consuming remedial measures.
 Poorly planned construction schedule. The illogical sequencing of
construction tasks caused a number of delays:
 Monsoon rains restricted access to the site as the access road had
not been sealed. The access route should have been sealed well
before the arrival of the monsoon.
 Modules were damaged (and were at risk of theft) as they were
stored unprotected on site for long periods of time. Modules and
other valuable components should not be delivered to site until
shortly before they are required. If they must be delivered earlier
then they should be stored in a controlled and secure environment.

12. Quality issues in construction
 Foundations in incorrect locations.
 Poor alignment of foundations.
 Cracked and damaged foundations.
 Elements of the supporting structure left unattached.
 Poorly aligned solar modules.
 Damaged solar modules.
 Poor attention to detail in finishing of substation buildings.

13. Commissioning of the project
Commissioning should follow the procedure described in IEC
62445 and prove three main criteria:
 The power plant is structurally and electrically safe.
 The power plant is sufficiently robust (structurally and
electrically) to operate for the specified lifetime of a project.
 The power plant operates as designed and its performance
is as expected.

14. Commissioning
Open Circuit Voltage Test
This test checks whether all strings are properly connected (module and
string polarity) and whether all modules are producing the voltage level as
per the module data sheet. The test should be conducted for all strings.
The open circuit voltage, Voc, should be recorded and compared with
temperature adjusted theoretical values.
Short Circuit Current test
This test verifies whether all strings are properly connected and the
modules are producing the expected current. The test should be
conducted for all strings. The short circuit current, Isc, should be recorded
and compared with the temperature adjusted theoretical values.

15. Grid Connection
 Grid connection should only be performed once all DC
string testing has been completed. It is likely that the
distribution or transmission system operator will wish to
witness the connection of the grid and/or the protection
relay.
 Such a preference should be agreed in advance as part of
the connection agreement.
 The grid connection agreement often stipulates the level of
parameters—such as electrical protection, disconnection
and fault—to which the PV power plant is required to
adhere. Usually, these conditions need to be met before
commissioning the grid connection.

16. Post Connection Acceptance Testing
Once the power plant is connected to the grid, the inverters will be
powered up according to the manufacturer’s start-up sequence.
Inverter internal meters and displays should be verified prior to use.
Post grid connection should include:
• DC current test.
• Performance ratio test.

18. Operation and Maintenance
Maintenance can be broken down as
follows:
 Scheduled or preventative
maintenance – Planned in advance
and aimed at preventing faults from
occurring, as well as keeping the
plant operating at its optimum level.
 Unscheduled maintenance – Carried
out in response to failures.
