Interview

Solar Sector: Charged up for growth

With more than 13,000 attendees and 241 exhibitors engaged in meaningful conversations, Intersolar India concluded on a happy note.

Compared to solar’s share of 31.9 per cent in the first half of 2017, solar accounted for 39 per cent of new installed capacity additions at the end of the third quarter. As long as solar remains cheaper than coal, it will continue to overtake it as the fastest growing energy generation source, bringing with it tremendous environmental benefits.

The positive market situation created a very optimistic atmosphere on the show floor during Intersolar India 2017. More than 13,000 attendees and 241 exhibitors engaged in meaningful conversations about the best approaches for sustained market success. With the special exhibitions ees (electrical energy storage) and Power2Drive, Intersolar India has set the next steps for the energy transition in India. Around 50 companies showcased electrical energy storage solutions on the show floor – highlighting the ever-increasing importance of stabilising the grid in India. In addition, battery industry professionals shared their views on how to steer developments in India more actively at the presentation stage.

Various product launches, award ceremonies and the sold-out networking event “Solar Power Developers Night” have highlighted the event as an important meeting and business gathering point for the complete solar and energy storage industry in India. Here we highlight some of the key highlights of Intersolar India 2017.

Spark Solar’s 120 Cells Rapid Series
Spark Solar is a globally renowned Indian manufacturer of high-performance solar panels. Capitalising on its strength in solar panel manufacturing, it is committed to provide panels with unparalleled efficiency, and reliability to enable customers to maximise the returns on their PV projects.

Saurabh Jakhotia, Director, Spark Solar says, “The company has evolved as reliable solar module manufacturer. It has presence across India, Middle East and US. Spark Solar has gained admirable reputation with an un-paralleled growth with consistent quality in solar industry.”

Commenting on the company’s participation at Intersolar India 2017, he adds, “We have launched new solar panel – 120 cells rapid series and received quiet good responses. World-wide only a very few companies are making this type of modules.”

Spark Rapid 120 cells series module produces energy even if part of the module is shaded. Whereas if standard module is partially shaded minimum one string will completely stop producing power, this accounts to one third reduction in power generation. Moreover, it can even completely stop generating power if shaded across its breadth. Rapid 120 cells series module is split into two parts. Each section of 60 half cut cells generates power on standalone basis but combines again before current exits the module. This structure results in power generation in non- shaded area of the module even if one of the sections is partially or completely shaded, resulting in higher overall energy yield as compared to standard module.

Features for Spark 120 Cells Rapid Series

  • High power density: High conversion efficiency and more power output per square metre.
  • Durability: Durable PV modules independently tested for harsh environmental conditions and known PID risk factors.
  • PID resistant: Advanced cell technology and qualified materials lead to high PID resistance.

RelyOn launches SCADA to monitor solar power plant health
RelyOn Solar, a leading company in India’s solar power sector, unveiled its SCADA – an Advance Monitoring System built on IoT platform. It helps in monitoring the health of solar power plants and is capable of Real-time data acquisition and analytics.

According to Suhas Pansare, Vice President- Sales and Marketing of the company, RelyOn Solar’s SCADA is capable of historical data collection and analysis and can assist in creating customised charts and performance analysis. The product assists the users in decision-making through trends and the user can also take actions based on the data analysis to improve the Plant performance. In case of any plant-related issues, the user can directly check the origin from across the world and take necessary action. This helps in increasing the plant uptime and hence improves the generation of the plant.

“It is also a great tool for optimising O&M. The system is capable of maintenance scheduling and tracking making it easier to keep the process on track,” he adds.

As the solar industry is growing it’s becoming increasingly competitive. With the reduction in solar tariffs, today viability of projects is dependent upon increasing the output of the plant. “With RelyOn Solar’s SCADA one can stay competitive and improve project returns, reduce operating costs and lower the LCOE,” Pansare said.

The SCADA launch is an effort towards building a tool to take solar closer to assured power. Various technologies are essential to accomplishing this in a cost-effective manner including the development of accurate forecasting and prediction capability. “Through enhancement of SCADA platform, we will develop energy forecasting and day ahead prediction capability to make the solar primary source of energy,” Pansare asserts.

With the service and support network across 16 states in India, RelyOn Solar SCADA has to capability provide its customers the best assistance for improving their project viability.
