ITC Steel Tariffs : How are they affecting your project?

ITC Steel Tariffs : How are they affecting your project?

Steel Tariffs Introduced in March for Solar Industry

As many of us know, March of 2018 was a volatile month for the solar industry, as steel tariffs up to 25% were imposed on manufacturers and steel importers to the United States.  In January, the International Trade Commission acting on orders from the President imposed an import tax or tariff on various products including solar panels, which immediately caused a number of utility scale projects to be halted until financial profitability could be once again guaranteed.  As a result of the steel tariffs imposed in March, a number of these utility scale projects are once again put on hold, while companies scramble to make projects profitable once again.

Quality Materials Reign in Utility Scale Solar

On March 22, 2018 the White House announced that it would offer exceptions to the tariffs to Mexico, Canada, The European Union, Australia, Brazil, Argentina and South Korea.  It is said that these exceptions were made due to political/trade relations and QUALITY OF MATERIALS PROVIDED.  As you can imagine, many utility scale solar manufacturers have not only had to completely adapt their supply chain, but also have lost a number of projects because of the use of inferior materials.  Though the tariffs are impacting almost every manufacturer in the US, there are some bright spots to be found.

Where Does the Steel Come From In Your Solar Project?

Sun Action Trackers is one of the only Solar Manufacturers globally that sources our steel from South Korea.  Our Magnesium Alloy Coated (MAC) Steel is sourced from POSCO and is in many ways a highly superior product.  Through UL testing and certification, we are able to prove our products resistance to harsh environments and its self healing capabilities.

We at Sun Action Trackers were pleased to learn of the steel tariff exemption allowed for South Korea.  This exemption allows us to continue to offer POSCO’s superior steel products at an even more competitive price.

This could mean a possible advantage for your projects by installing a better material at a lower cost than other imported options.  If you would like to learn more about how Sun Action Trackers can help your project get back on track, or to learn more about our Dual Axis or Single Axis Solar Trackers, please feel free to CONTACT US for more information.

Come See Sun Action Trackers at MIREC Week

Come See Sun Action Trackers at MIREC Week

Visit Us in Booth 59 at MIREC Week

Its that time of the year again, when Mexico and Central America converge on Mexico City for MIREC Week.  This week of renewable focus also hosts the Corporate and Industrial Energy Summit in conjunction with the exhibition.  Over 300 expert speakers will also be sharing insights with attendees and industry experts alike.  This year, MIREC Week will also be streamed live through 6 separate streams insuring that all insights will be documented.  There is also a host of networking and after conference events nightly to engage and foster connections in the solar industry.

Sun Action Trackers is proud to be an exhibitor at MIREC Week and we would love to meet you!  Please visit us in booth 59 for information regarding our new DUAL AXIS RESIDENTIAL models as well as our utility/commercial scalable Single Axis and Dual Axis Tracker offerings.  Our team is ready to speak with you about something that we are very passionate about, and we would love to show you what the future will hold for the solar industry.  More capable, More flexible, and More efficient.

Carefree Operations and Maintenance – Part 2 – Less Is More

Carefree Operations and Maintenance - Part 2 - Less is More

By Sun Action Trackers

In Part 1 of our Carefree Operations and Maintenance series, we discussed Land O&M and various solutions to lower costs and minimize financial risk, while maintaining an “eco-friendly” approach.  In Part 2 of our series, we will be discussing the complexity of system designs and how they affect your overall O&M costs over time.  There are a wide variety of issues to take into account when evaluating O&M costs during the lifecycle of your project.  These issues could include such variables as system design, environmental variables and materials used in the project.  In this article we will be focusing on System Design.

Keep it Simple Solar (KISS)

In previous articles, we have mentioned this approach which we have found to be most effective when tackling O&M costs over time.  By focusing on hyper-simple design, O&M costs of systems designed by major manufacturers are getting lower and lower as systems become more refined and efficient.  Though approaches vary widely, there are a number of innovative designs and options for your project.  Sun Action Trackers’ PST-1AX6 Single Axis Solar Tracking solution highlights a number of innovative additions to lower O&M costs initially and for the lifecycle of the project.

Linked vs. Independent Row Designs

Linked Row Solar Arrays or “centralized tracker designs” move multiple rows of solar trackers with a single motor or actuator, whereas Independent Row or “decentralized tracker designs” require 1 motor or actuator per row.  Though the decentralized tracker designs offer some flexibility for land usage, the centralized tracker systems are much more efficient with 25% of the moving parts than its counterpart.  Less moving parts lowers the potential for system failures, while also requiring less time to maintain the system overall.  In many cases, linked row systems will also require “leveling” of each row to allow the systems to work.  The Sun Action Trackers’ PST-1AX6 single axis solar tracker however does not require grading or leveling to make our system work properly.

Figure A

Replaceable Parts

Linked row and independent row systems also differ greatly in the number of motors that are needed to make the entire system.  Figure A highlights an 800Mw project using 8 actuators to run the entire system vs. 28 motors on the independent system as each row requires its own powered motor.   Each row also requires its own control box and sensor opposed to the linked row system that uses 1 control box and sensor for every 6 rows. This means a significant increase of energy usage to use the tracker system, and more moving parts to replace and fix moving down the road.  As another question, Which do you think would require more operations and maintenance attention?  1 actuator and 1 sensor, or 6 motors and 6 sensors?

Figure B

Ground Mounting

Even before tracker construction can begin, the pilings must be poured and secured before steel construction can begin.  Figure B illustrates linked row systems vs. independent row systems.  As you can see, the linked row system only requires 48 pilings per 100 Kw compared to 56 for the independent row system.  This makes a difference in future foundation maintenance and installation time.

Key Takeaways

When it comes to single axis solar tracking: Simple is King.  By limiting replaceable parts that could potentially fail during design and engineering, you will ultimately lower your Operations and Maintenance costs across the board.  Minimizing points of failure is going to lead to a system that consumes less energy thus maximizing total production of the system.  If you want to make your project more efficient, KEEP IT SIMPLE SOLAR.
