HINESE MAJOR LAUNCHES ROOFTOP SOLAR ENERGY SOLUTIONS IN INDIA

Chinese solar energy solutions provider Trina Solar has launched solar energy kits under the brand Trinahome to cater to the renewable energy needs of household and small and medium enterprises (SME) sector in India. Trinahome will come in three sizes -- 3 kilowatts (KW), 5 KW and 10 KW -- and will contain all components such as the solar modules, inverter, grid box, mounting system and other accessories as part of the all-in-one product pack. With just 1.3 giga watt (GW) installed capacity so far, rooftop or home solar energy solutions is still in its infancy in India.

Industry Insights FOUR TRENDS LEADING GROUND-MOUNTED SOLAR IN 2018 DEMAND FOR GROUND-MOUNTED PV HAS BEEN THE PRIMARY DRIVER OF GROWTH IN THE UNITED STATES

PV INSTALLATION FORECAST BY INSTALLATION TYPE - UNITED STATES

The United States has become one of the largest solar photovoltaic markets in the world, primarily driven by demand for ground-mounted systems. To put this in perspective, IHS Markit forecasts the U.S. market will deploy 37 GWdc of PV from 2016 to 2018, with ground-mounted systems accounting for over 70 percent of installed PV capacity during the period. After the rush of development and installations in 2016 due to the late extension of the Federal investment tax credit (ITC), the U.S. PV market experienced decline in 2017 as the project development pipeline replenished and set targets

on opportunities in 2019 and beyond. Due to recent trade policy dynamics, 2018 could lead to a second year of decline for the U.S. PV market if new tariffs result in significant price increases for PV technology. IHS Markit currently assumes that a new 30 percent tariff on imported PV cells and modules will be implemented in Q1 2018 [the decision was not made at presstime], increasing the base price of PV modules in the United States and negatively impacting demand for utility-scale PV solutions during the year. But even as the market for ground-mounted PV in the United States faces decline in the near-term, it remains a multi-gigawatt opportunity. When the market experienced its greatest demand for ground-mounted PV in 2016, leading markets included familiar states such as California, North Carolina, Utah and Nevada. Increasingly, emerging markets are accounting for more ground-mounted PV demand in the United States. IHS Markit projects that Texas, Florida, Minnesota and Virginia will also be top markets in 2017 and 2018. Primary drivers of growth in such markets include the emergence of new renewable energy policy initiatives, attractive project economics for customers and utilities, and the developing interest of traditional energy companies.

SINGLE-AXIS TRACKING HAS BECOME THE DOMINANT TECHNOLOGY CHOICE FOR THE GROUND-MOUNTED MARKET IN THE UNITED STATES, PRIMARILY DUE TO CONTINUED PRICE REDUCTIONS AND IMPROVED ENERGY YIELDS Single-axis trackers have become increasingly popular in the United States in recent years, growing steadily in market share from 2014 to 2016 to 70 percent of market share compared to fixed-tilt systemsin terms of megawatt shipments. From 2017 to 2018, IHS Markit forecasts the share of fixed-tilt systems for ground-mounted systems will remain relatively stable as demand for such solutions remains strong in markets with lower solar resource, incompatible weather patterns, less than ideal land types,

Energy storage technologies have the potential to offset the intermittency problem of renewable energy sources by storing the generated intermittent energy and then making it accessible upon demand. A widely-used approach for classifying EES systems is the determination according to the form of energy used. The figure below compares several storage technologies as per their commercial maturity. Pumped hydro and compressed air energy storage are the most advanced electricity storage technologies (in terms of commercial and technical maturity and deployment); others bring cost and risk premium due to their lower levels of commercial maturity. As technologies move from demonstration and deployment stage to commercialization, the cost of the technology reduces and the technical characteristics are often enhanced. For example, in certain technologies such as Batteries, technical progress to date has seen the overall improvements in efficiency and lifetime of the storage

and

restrictions. At present, world over around 1643 energy storage projects have been installed with an accumulated capacity of 193 GW9 . The vast majority ~ 94% of this capacity is based on pumped storage technology. Others include electrochemical, electro mechanical, thermal storage etc. There are approximately 1000 electro–chemical (batteries) storage projects that have been installed world over with an overall capacity of 3.4 GW10. This is mainly due to falling cost of batteries and improving technology, batteries as a means to store energy is likely to scale up significantly.

ECONOMICS OF ENERGY STORAGE TECHNOLOGIES …and due to expected improvements in economics of the storage solutions over the next few years. Technological improvements are one of the major drivers of falling costs of energy storage system world over. The figure below compares the cost of energy storage across major energy storage technologies – Pumped Storage, Compressed Storage, Lead Acid Batteries, Lithium Ion Batteries, High temperature batteries, Redox flow batteries and Flywheel. The cost of most of the energy storage solutions in today’s context is considered expensive. However, for several storage technologies,

to fall by another 72% by 2030, bringing the overall cost of lithium ion batteries down to USD 73-74/KWh14. This correlation, between cost and volume of production can be attributed to economies of scale, as well as manufacturing and engineering improvements that are likely to emerge by 2030. Given this trend, the prices of energy storage technologies are likely to fall between 30-60% range 15, depending upon technology under consideration. Thus, the falling cost of storage and improving technology in terms of life and range clearly can enable greater penetration of wind and solar in the grid, especially for India. However, policy and regulatory mechanisms will be required to facilitate integration of energy storage in the Indian Power System. A debate is required around how to incentivize capacity market for grid balancing in the interim period, while continuously promoting Energy Storage as a long term solution for Grid Integration.

VISION STATEMENT

BUSINESS COMPETITIVENESS

TEAM & MANAGEMENT

Price competitiveness is the foremost issue faced by solar equipment manufacturers. As a fact, India still imports 8890% of its total solar panel requirement. This gives a very limited breathing space to plethora of solar PV manufacturers in India. The inability to compete with imported equipment in terms of price, ultimately leads to fierce competition within the Indian manufacturers for limited number of avenues using Indian made solar PV equipment.

Saatvik, being a young company, managed by people in 20’s and early 30’s, has very dynamical horizontal organizational structure. Saatvik believes in smaller team and greater efficiency. This way, every person working for Saatvik feels a sense of ownership.

Quality Policy Of The Company: ISO ratings, standards & specifications etc. Not only does Saatvik comply with ISO, but it has also implemented SAP H4 HANA which helps in automating a lot of manual processes, for superior records and quality implementation. If your people and processes are sorted, precision comes naturally, and we are a very quality conscious company, hence precision plays a very important role. To assist our people and processes, we have all necessary quality control/inspection equipment both in-line and in the laboratory, to ensure precision in our production for highest quality products.

CUSTOMERS & PROJECTS Saatvik has been able to make a good portfolio of customers already, including India’s leading IPPs and solar developers, apart from regional and national EPC companies. Saatvik solar modules have been successfully installed at various government buildings, government utilities, railway stations, hotels and universities, such as Delhi Jal Board, DMRC, Western Railways, Ambala Airforce Station etc. Saatvik’s constant strive towards quality, delivery and commitment has made its products lucrative to many clients, and will continue to do so in future.

At Saatvik Green Energy, we actively support the global effort to energise the world through alternate and greener sources of energy, by manufacturing and distributing world class solar photovoltaic modules, globally. We seek to attain and establish our position as the most reputed, customer centric, significant solar module provider to Solar Industry.

Tech-Insights PV SYSTEM COMMISSIONING – PERFECTION IS THE KEY! Effective management of a solar PV plant could be divided

FIGURE 1: CHECKING OF STRUCTURE (ON LEFT) & A ROOFTOP PLANT (ON RIGHT) COMMISSIONED BY WAAREE

into 3 distinctive steps i.e. Engineering Procurement & Construction (EPC), Commissioning and Operations & Management (O&M). EPC deals with the pre-construction and construction activities of the PV power plant. Commissioning is the process that starts along with the construction of plants and proceeds through PV system acceptance. It also deals with the necessary documentation processes required for system acceptance. O&M deals with processes and/or actions required for maintaining and operating the power plant to its maximum capacity. While a lot is known and talked about EPC & O&M, a little is known about commissioning, which is a mandatory and significant process. For a novice in the solar field, it is important for him to know what the important process/checks while commissioning

VERIFICATION AND DOCUMENTATION OF INSTALLATION Amongst the first of the steps would be to verify the entire installation and ensure that it is complete and matching with the power plant which was initially designed without any deviations.

It also includes checking the module alignment which should look perfect in-line with other modules (as shown in Figure 1). This would ensure that the installation is robust and aesthetically

However, a day before energizing the inverter the grid side/AC side transformer is energized while the inverter and module remain isolated (i.e. AC breaker of inverter is kept open) (top side of Figure 4). This is to ensure that the transformer generates ingress current (which is the current generated via magnetic coupling) in a way that there is no problem during its further operations. On the next day, the entire plant is energized and its output voltage, current and frequency are monitored. In case of inverter tripping, ground faults in the plants are checked for.

of the power plant, there are always certain deviations from it. Not only is it important to exactly locate such deviations (at micro level) but it is also important note such deviations for a power plant. One of the best solutions is to document the entire plant along with the deviations or document asbuild conditions. This document shall preliminarily help the O&M team to closely monitor the deviations for any potential problems. In the longer run it would help the team to understand any fault if arising due to such deviations and

of plant, testing is the next most important step in commissioning. The testing includes but not limited to PV module, earthing, inverter, wiring, etc. One of the first tests performed is to check the insulation resistance of conductors. This test measures insulation of conductors ensuring that there is no leakage current via conductor (shown in Figure 2). With the plant being expected to last for 25 years, the conductors shall be exposed continuously to altering weather conditions. Such alterations could lead to degradation of insulation which in the long term could compromise the safety of power plant. Thus recording the resistance value at the beginning and tracking it over the course of plant’s life would give significant information over conductor’s deterioration and hence its quality. At module level, random or all (in case of small rooftop

happens at line side of DC disconnect whereas for larger inverters, such measurements happens at line side of combiner box with its fuse open. Obtaining a similar voltage in all the strings means that all the strings have similar number of modules with correct polarity. A similar exercise to measure the maximum current of string (Imp) is carried out by a DC clamp meter. The output for different strings if within range of ± 0.1A signifies that the orientation and tilt of the strings is same. While the above testing happens when the plant is

We ensure to follow all the safety standards and necessary guidelines in order to erect a power plant. An expertise like such enables end customer to be assured that their plant would be up and running for 25 years.

Solar panels, which constitute 60-70% of the cost of solar projects, are taxed at 5% GST. Maharashtra’s appellate authority for advance ruling (AAAR) on 5 September set 18% as GST on solar projects, endorsing an earlier ruling by the state-level authority for advance ruling (AAR) and dismissing solar developers’ demand to be taxed at a lower 5%. Previously, the AAR in Rajasthan too had declared 18% as the GST rate for solar projects.
