Solar Module Manufacturer:

A solar module manufacturer manufactures the solar modules in the solar industry and sells them to the EPC Player. 

Tata Power Solar is a solar modular manufacturer. The module manufacturing lines have an in-house production capacity of 400 MW for modules.

What is the meaning of EPC Player in Solar?

EPC Player means Engineering, Procurement and Construction Player. It is a particular form of contracting arrangement where the EPC contractor is made responsible for all the activities from design, procurement, construction, commissioning and handover of the project to the end-user or owner.

Why is the EPC Player in solar Important?

EPC Player is the person who is responsible for your solar rooftop efficiency. He is the main person/company with whom you are concerned, and have legal bindings.

It is one choice, the selection of which can make or break your investment in solar. It greatly affects the return on investment. 

Important criteria to consider while choosing the EPC Player in solar.

Chances of EPC Player shutting down within 25 to 30 Years

Shut down

Since the solar plant has a long life of more than 25 years, the EPC Player becomes very important. The chances of survival of small players and local players lasting for such a long period is small. 

The shutdown can be triggered by any of these events happening: 

  1. The death of the owner, 
  2. The firm going insolvent, 
  3. The firm makes losses from solar etc. 

This is especially true in the solar industry. R&D, product & price changes, changes in government policy are very frequent, the chances of loss-making hence are huge leading to the vanishing of the small players.

Experience of the EPC Player in Solar

The products used should be of Tier-I brand only,  only the best brands can survive so long. 

Technical Expertise of EPC Player

There should be a good technical team to support. There are many challenges at the time of designing and installation. Unless the team is good even if the good products are procured the efficiency of the solar plant will be sub-optimum.

Financial Status  of the EPC Player

If the financial status is not good the company may not be able to overcome the rough weather often coming in the solar industry: Falling prices, rapid changes in the product, increasing no. of suppliers, reducing margins etc. Check the financial accreditation from reputed accreditation agencies such as  CRISIL, ICRA, CARE and Fitch, which will prove the financial position of the company

Vertical Integration:

A player with vertical integration is likely to have more advantages over only an EPC Player: They will have better technical know-how, more technical support, and will be more economical.

After Sales Support:

The response time should be fast in case of any problem. Else, you will be stranded in case of any malfunction of the solar rooftop system.

Vendor Credentials:

If possible ascertain the vendor core skills, competence and level of knowledge in solar power plant design and implementations, else check the vendor experience in the solar industry, the no. of projects handled, the size of the big projects handled, the recognition,  awards and ranking received especially related to the quality parameters from reputed solar agencies. ISO 9001 certification relates to quality management systems. ISO 14001 relates to environmental management systems. The ISO Certifications along with the past customer references give an estimated vendor credential.

Now that we have understood why Tata Power Solar is the best. Let us also look into the consequences of choosing a bad EPC Player.

The consequence of going for a poor quality  EPC Player in solar

Poor quality EPC Player

The causes of loss in the solar system can be many here’s a list of important performance aspects that could be compromised in your solar power plant by an average or a poor quality EPC: 

01.Solar Module: The quality of the cell, ethylene-vinyl acetate (EVA), back sheet and glass that’s been used in the modules makes a big difference in the degradation that will take place in the modules with the passage of time. Only Tier I modules should be used in solar plants. 5 kinds of losses occur in solar modules which were covered separately in my earlier article.

Here is the link for it. https://horizon4u.co.in/solar-plant-information/solar-panels/

02. Inverter: It is the most intelligent device in the solar system which controls and regulates the power coming from Grid, Solar, Generator etc. The efficiency of inverters will affect the output that we get from the solar system.  Among the components failing in solar plants, inverters occupy the topmost rank. Hence it is essential to have a Tier-I inverter. 

03. Corrosion in mounting structure: If the galvanization layer of the mounting structure is not thick enough it will lead to structural failures after a few years of installation. A high-quality EPC, in this case, will be proactive in ensuring the procurement of an optimum galvanized structure. 

04. DC-side SCADA monitoring: This is one factor that is not emphasized by an average EPC which just goes for an inverter–level monitoring system. Analytics on the DC side, e.g. string-level monitoring, implemented by a good EPC can lead to big improvements in revenue losses. 

05. Plant Designing:  For Proper site designing many inputs are critical, which will directly affect the output and the savings that you will get from the solar system. 

The details of the power outage during the day and during the night,  shadows that will be formed during different seasons and times of the day have to be analysed, the power backup if required for how many hours has to be defined. If the above factors are not considered properly, it will directly affect the utility/savings that you will get from the solar power plant. The designing defect may itself lead to 10% to 20% loss.

06. Plant Installation: Good Designing with improper installation, will offset all the advantages of good design. The main factors to be considered during installation are:

a. Cable Sizing: To reduce costs, if the under-sizing of the cables is done or bad quality of the wire is used or cable length is not optimized, it will lead to proportional power loss with respect to the plant output. 

b. Cable Laying and installation: If the connectors are of inferior quality or the junction fittings have loose connections, or the cable joints are not as per standards. All of these will result in power leakage, heat generation, carbon deposit, poor electricity flow, electricity surges and glitches, resulting in deterioration of the power output and reduction of the life of the equipment.

c. Earthing: If proper earthing is not done, in case of electricity leakage, it can become life-threatening, the potential induced differences may lead to deterioration of the PV system, reducing its life and output.
