US Solar Industry Supply Chain Disruptions: The COVID-19 pandemic disrupted global logistics systems, causing delays in essential equipment delivery to solar farms, leading to rising solar costs and reduced US industry growth. NextTracker's response: building more US manufacturing facilities, catalyzing over 20 factories, and manufacturing over 30GW of components domestically, creating jobs.
The COVID-19 pandemic caused significant disruptions to global logistics systems, leading to delays in the delivery of essential equipment to solar farms and causing solar costs to rise for the first time in a decade. This issue, compounded by policy uncertainty, led to reduced growth forecasts for the US solar industry. In response, NextTracker, a leading solar tracker company, accelerated its strategy to build more US manufacturing facilities to serve local markets and reduce reliance on overseas supply chains. This retooling effort has resulted in the catalyzation of over 20 factories across the US, with over 30 gigawatts of major components being manufactured domestically and shipped today. This not only addresses the supply chain crunch but also leads to a surge in US solar jobs.
US manufacturing resurgence: The Inflation Reduction Act and focus on secure supply chains are driving a manufacturing revival in the US, particularly in the clean energy sector, through a hybrid strategy of local production and leveraging existing infrastructure.
The Inflation Reduction Act and the push towards making supply chains more secure are leading to a resurgence of manufacturing in the US, specifically in the clean energy sector. This is evident in the revival of old manufacturing facilities, such as the one in Leedsdale, Pennsylvania, which was once a major steel production hub during World War II. The hybrid strategy of manufacturing locally, while also leveraging existing infrastructure and know-how, is making this transformation possible. For instance, NextTracker, a solar tracker technology company, has tripled capacity at their steel facility in this location. This is just one example of the many manufacturing comebacks happening across the industry. Overall, the IRA is not just about reducing inflation, but also about creating jobs and re-industrializing America.
IRA's impact on clean energy industry jobs: The Inflation Reduction Act (IRA) has led to over 100 new factory announcements in the clean energy sector, contributing to re-industrialization, job creation, and reducing the carbon footprint through the use of recycled materials.
The Inflation Reduction Act (IRA) is making a significant impact on the clean energy industry and creating high-quality, enduring jobs in the US. This was evident during a visit to Nexttracker's solar manufacturing facility in Pittsburgh, where the granddaughter of an original Bethlehem Steel worker was now producing solar products. The use of recycled steel in the US has helped reduce the carbon footprint of raw material production in this industry, which is notoriously difficult to decarbonize. The IRA's passing has led to over 100 new factory announcements in the clean energy sector, contributing to a larger trend of re-industrialization and job creation. Looking back a decade from now, the IRA is expected to be seen as a major jobs bill that helped turn the economy around during a time when there were concerns about a recession. The combination of the IRA, the bipartisan infrastructure bill, and the CHIPS Act has created a strong momentum for re-industrialization and getting people back to work, resulting in historic low unemployment rates and record-breaking values on Wall Street.
Solar tracker innovation: Solar tracker innovation, particularly independent road tracker systems, enhances large-scale solar projects' efficiency and sustainability by enabling mobility, simplifying vegetation management, and streamlining panel cleaning and operations and maintenance.
The shift towards renewable energy and solar power in particular, has seen significant advancements, especially in tracker design. This transformation comes at a crucial time when the world needs more power than ever before. The IRA policy's onshore focus could not have been more timely. I've been involved in solar since the 1980s, and my colleague Howard Wanger and I have been advocates for trackers throughout. Our company, Next Tracker, has built on this foundation, with Howard's solar simulation software, PV Grid, playing a key role in our decision-making. Thirty years ago, we chose single axis tracking on horizontal trackers as the most effective solution for solar at scale. However, we faced challenges with mechanical impediments from vehicular traffic when using linked row trackers. To address this, Next Tracker developed an independent road tracker system, which not only enables mobility through the tracker field but also simplifies vegetation management, panel cleaning, and operations and maintenance. This innovation is a game-changer for the solar industry, making large-scale solar projects more efficient and sustainable.
