Focus on Environment - Only EPC to offer end of life recycling- Poseidon Solar is the only recognized recycler outside EU by Brussels headquartered PV Cycle. The company has a fully automated facility near Chennai.

Partnership

Singapore based Cleantech Energy Corporation (CEC) is a pan-Asia investor, owner, and operator of solar plants with focus on the commercial and industrial sector operational in India with a wholly owned subsidiary.

Together, we design, construct, own, and operate solar plants on a build-own-operate-transfer (BOOT) model.

Within six months of inception, we have created a portfolio with 1 MW in operation, 2.5 MW under execution, and a solid forward pipeline of ~10 MW.

We are well capitalized and have a fully streamlined execution process. We pride ourselves in delivering the operating plant to customers within 90 days of deal close

What is the definition of Best

Practices?11

“Commercial or professional

procedures that are accepted or

prescribed as being correct or most

effective”

What is the need for best practice?

12

India has set to add 100 GW of solar power in the

next decade.

Close to 30% of that is expected to be on the

rooftops of buildings.

TORP expects 80% of these on the roof of Industrial

and Commercial buildings.

Therefore, it is important to address and prepare “Best

Practices” for the installation of solar systems.

What is the need for best practice?

13

Improve solar asset transparency for investors

and rating agencies;

Provide an industry framework for quality

management;

Reduce transaction costs in the solar asset

securitization process;

Eliminate accidents and improve worker

safety

Building Owner Vs System Owner

14

A big majority of solar plants is being built on

the OPEX model via a long-term PPA;

This is one of the significant reasons for the

growth of the solar industry;

Most solar project developers (system owners)

are from the financial industry;

Building owners generally negotiate on the

lowest tariff and do not get involved in spec

building.

Why is Specification Important?15

The quality and integrity of the system on the

roof is a function of the specifications;

Most people only speak about solar panels and

inverters. There are several other materials that

go into building a solar plant;

All these have to work together for 25 years – it

is not sufficient for the panels to work for 25

years.

Materials used should support sustainable

recycling at end of life.

Things to consider – Structural16

Installing PV panels onto roofs introduces hazards that

can affect the structural integrity

of the roof.

Dead load from Panels;

Wind loads on panels that are transmitted to the

building;

Roof leaks;

Additional footfall – is there provision for safe

walking on the roof?;

Corrosion of roof due to material mismatch

Things to consider – Contractor17

Most System developers use contractors to build their

PV plants on Clients roofs. Clients must ensure the

contractor has:

Sufficient experience;

Has built plants with no cases of safety incidences;

Takes insurance for man and materials;

Employs people with electrical license;

Provides Safety & Quality Plan;

Things to consider – Documentation

18

Before starting work on site EPC to ensure that the

following documentation is completed:

Electrical & local regulatory requirements

Electrical Consumption pattern – study of typical

daytime power demand and superimpose solar

power generation.

Plant Layout; Electrical SLD;

Mechanical Structures designed for IS875;

Specific area for material storage;

Things to consider – Diesel Generator

Integration19

If the plant will be synchronized to a diesel generator,

a few points will have to be considered:

What is the ratio of the PV plant capacity to the

DG capacity;

Will there be a situation when the demand is very

low compared to DG capacity (this may happen on

holidays/plant shutdown etc);

During these times how do you prevent reverse

power feed to the DG?

Things to consider – Electrical Design

20

Is the DC string length safe considering all weather

conditions?;

Is the inverter capacity adequate?;

Is the system connected to a dedicated Earth?

Does the system need a lighting protection system?

Are the other BoS with relevant certifications?

Are all cables routed clearly and secured in cable

trays?

Are cables labeled for easy identification?

Example of poor installation21

Poor alignment

Corroded structures

Open cables

Summary22

Remember – it is YOUR roof and YOUR assets are

under it.

Make sure that you take part in the selection of

materials and Contractor.
