From pv magazine India More than 250 million households across India have the technical potential to deploy 637 GW of solar energy capacity on rooftops, according to a new independent report by CEEW. The researchers said that rural areas have a higher technical rooftop potential of 363 GW than urban areas (274 GW) considering the residential rooftop area. Residential willingness to install rooftop Solar mounting systems is the highest in Gujarat at 13%, while the national average is 5%. The report stated that deploying just one-third of the 637 GW solar potential could meet the residential sector’s entire electricity demand of 310 TWh. The overall technical potential reduces to one-fifth (118 GW) after factoring in the current electricity consumption of households. “Most residential consumers fall into low-consumption slabs and solar may not be economically feasible for them without financial support even though it is technically possible,” said CEEW. The potential reduces further to 11 GW when no capital subsidy is considered. “The payback period for rooftop solar is restricted to five years and we factor in consumers’ willingness to buy fixed adjustable brackets,” explained the researchers. However, with the Ministry of New and Renewable Energy’s capital subsidy, the researchers noted the potential to increase to 32 GW as the subsidy makes the solar systems feasible for more consumers.

Photovoltaic brackets are referred to as the "skeleton" of photovoltaic power plants. They are special structural components designed to support, fix, and rotate photovoltaic modules in photovoltaic power generation systems. Together with photovoltaic modules, combiner boxes, inverters, and other core equipment, they form the photovoltaic power generation system. As an important supporting structure in the photovoltaic system, its core requirements are safety and ease of installation. Solar mounting systems are mainly composed of columns, main beams, purlins, welding parts, and foundations. They can be divided into fixed brackets and tracking brackets based on whether the angle can be freely adjusted later. Among them, fixed brackets can be further divided into fixed brackets and fixed adjustable brackets, and tracking brackets can be divided into single-axis tracking brackets and dual-axis tracking brackets. The market size of the photovoltaic bracket industry expands with the growth of photovoltaic installed capacity. The overseas tracking bracket industry started early, with mature technology and higher recognition downstream. At the same time, the construction of large domestic projects and other factors have brought broad market prospects for the application of tracking brackets, which are expected to penetrate rapidly. According to the forecast of the China Photovoltaic Industry Association, assuming a capacity ratio of 1.2, the global penetration rates of tracking brackets from 2022 to 2025 are projected to be 60%, 64%, 68%, and 72% respectively. Assuming the average selling price of brackets changes by 0%, -3%, -2%, and -2% based on 2020, the total market size of brackets (tracking + fixed) in 2021 is estimated to be approximately 66.5 billion yuan, and is expected to reach 117.7 billion yuan by 2025, with a compound annual growth rate of 15.4%. The market size of tracking brackets in 2021 is estimated to be around 31.4 billion yuan, and is expected to reach 65.1 billion yuan by 2025, with a compound annual growth rate of 20.0%. The compound annual growth rate of the tracking bracket industry in the next five years will be higher than that of the fixed bracket industry.

Image: Pv-tech According to the Solar Energy Industries Association (SEIA), solar manufacturing jobs in the US are expected to more than triple in the next decade. Currently, the solar manufacturing industry provides around 35,000 jobs. However, with the US government's increased production efforts and significant investments in expanding domestic solar manufacturing capacity, this number is projected to reach 120,000 jobs by 2033. In Dalton, Georgia, Qcells plans to enhance its solar module assembly capacity by 2GW. An investment of US$2.5 billion will support the entire supply chain and create over 2,500 jobs. By 2024, the company's total solar panel production capacity in Georgia will reach 8.4GW. Additionally, in Cartersville, Georgia, Hanwha Advanced Materials Georgia (HAGA) will construct a new manufacturing facility for producing encapsulants, which are used to seal solar cells and ensure their durability. These encapsulants will be supplied to QCells for use in their module production. The Cartersville facility is expected to bring in US$147 million in private investment and generate 160 jobs within the industry. Georgia Governor Brian Kemp stated, "Since we first welcomed Qcells to our state in 2018, we've announced more than 4,000 related jobs for Georgians." Furthermore, in Memphis, Tennessee, PV tracker supplier Nextracker has collaborated with MSS Steel Tubes USA to establish a new factory specializing in the production of low-carbon steel torque tubes for solar tracking systems. These torque tubes play a crucial role in efficiently rotating PV modules for optimal sunlight absorption. This factory will create 129 jobs and contribute to millions of dollars in local economic investment. It will also support projects across multiple states, including Kentucky, South Carolina, Virginia, Mississippi, and Georgia. The expansion of the solar manufacturing industry, coupled with the development of solar mounting systems, demonstrates the growing significance of the solar sector in job creation, economic growth, and sustainable energy efforts within the United States.

Despite the pressure the pandemic has placed on supply chains and income levels, the number of people who source electricity from solar energy kits has continued to grow and has now reached 490 million. According to the “Off-Grid Solar Market Trends Report 2022: State of The Sector” report – published by the World Bank’s Lighting Global, International Finance Corp. (IFC), GOGLA, Efficiency for Access Coalition, and Open Capital Advisors – the number of people who use solar energy kits had grown by 70 million by the end of 2021, up from 420 million in 2019. The report attributes this result to continued sales, the longer lifespan of larger products, and current customers beginning to move up the “clean energy staircase.” This is where they have paid off or made savings from their initial solar energy kit and are able to purchase a new, often larger product and additional services. For instance, 3.8 million customers have gained access to solar TVs in 2020 and 2021. The adverse effects of the pandemic were most pronounced in 2020, translating into a 22% decline in solar energy kit sales. However, in 2021, the off-grid solar sector bounced back with a 10% increase in sales, the report finds. In pursuit of universal energy access by 2030, off-grid solar technologies are expected to play a critical role as population growth, particularly in sub-Saharan Africa. According to the report, off-grid solar represents the cheapest solution for 41% of new household connections between 2020 and 2030. But for many homes and businesses, the price of solar panel mounting systems remains prohibitive. The pandemic has also exacerbated the affordability challenge in the form of declining income levels and job losses. Therefore, the availability of consumer financing options, such as PAYGo, has never been more important. Assuming consumer finance is readily available, between 177 million to 277 million currently unconnected people are still unable to afford a Tier 1 solar energy kit, the report shows. In the absence of consumer finance, affordability levels drop even further. That is to say, of 733 million unconnected people around the world, only between 3 million and 167 million could afford to buy a Tier 1 multi-light and charging system upfront. “This indicates that end-user financing is essential to provide the poorest population with Tier 1 energy access, but that PAYGo is not sufficient to close the affordability gap,” the report said. Meanwhile, investments into the solar panel manufacturers continued to grow, surpassing $2.3 billion since 2012. However, most of the finance went to seven companies operating at scale, while those in their seed and start-up phase have found attracting financing more difficult. From 2016 to 2020, the industry saw yearly investment volumes plateauing between $300 million and $350 million, before reaching $457 million in 2021. This year is set to be another record-breaking year, the report states. In other findings, the report foun...

Germany's Federal Ministry of Economics and Climate Protection (BMWK) has launched a request for expressions of interest (EoI) in a bid to boost the country's solar PV manufacturing supply chain. The goal is to build up 10GW of solar PV manufacturing per year across the entire value chain, from silicon to modules, with a capacity of at least 2GW per year for modules alone. The EoI aims to encourage companies to set up manufacturing facilities in Germany and thereby increase the country's domestic solar manufacturing capacity. The BMWK has set forth a few requirements, such as a module efficiency higher than 24% and the use of recyclable materials in the manufacturing process. So far, the response to the EoI has been positive, with many companies expressing interest in setting up production facilities in Germany. This move towards domestic solar manufacturing is critical for Germany's economic security, according to Robert Habeck, Federal Economics and Climate Protection Minister. He stated that Germany needs its own production capacities for central transformation technologies and that this is not only a question of economic reason but also one of economic security. The EU's new subsidy framework offers opportunities for this, and Germany aims to take advantage of them. Starting with photovoltaics, the country hopes to establish permanent photovoltaic production in Germany by financially supporting lighthouse projects. This not only strengthens our technological sovereignty but also our energy-political sovereignty. Germany has long been one of the leading European countries in terms of solar technology, with companies such as Wacker Chemie, Meyer Burger, and Aiko Solar investing in research and development facilities in the country. In addition to this, the country is also a key market for solar mounting systems. German companies, such as Schletter and Renusol, are some of the leading solar mounting system manufacturers in the world. As solar technology evolves, the importance of the solar panel mounting systems increases. The mounting system serves as a critical link between the solar panel, which generates power, and the building's structure. In conclusion, Germany's efforts to boost domestic solar manufacturing capacity will help to ensure the country's energy security, while also nurturing its technological sovereignty. With innovation in solar panel technology growing by leaps and bounds, the country's solar panel manufacturers could be at the forefront of the next wave of progress in the worldwide shift towards renewable energy sources. article reposted from pv-tech.org
