Products Lines
Captive use Solar PV Systems TORP believes
that rooftop based solar systems with a
large share of captive use is the best and
most efficient method for speedy
implementation of large scale solar energy
plants. We provide total turnkey solutions
for any kind of rooftop system
Power Level Adjustor - We develop special
electronic control systems for preventing export
of energy to grid meet statutory and
regulatory requirements.

Solar-Diesel optimizer- We design and
manufacture diesel optimizer controller
for diesel generator synchronisation with
solar systems
Smart Display Units - In-house designed
and manufactured display unit helps
monitor real time system performance

Innovations and Best Practices
Project Management – Provide web based project management and Schedule Tracking- Transparency in operation
Monitor real-time system performance – Systems installed with alarm systems via SMS for solar plants-Ease in maintenance and complete event logging in both AC and DC side.
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?
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.
