In order to better meet the special scenario-based needs of offshore PV and provide higher customer value offshore PV solutions for the application side, Trina Solar recently released the "Trina Solution" for offshore PV modules, hereinafter referred to as "TRW Solution" from the overall system solution to the reliability test of module components.At present, offshore photovoltaics are developing rapidly. In order to better meet the special scenario-based needs of offshore PV and provide higher customer value offshore PV solutions for the application side, Trina Solar recently released the "Trina Solution" for offshore PV modules, hereinafter referred to as "TRW Solution" from the overall system solution to the reliability test of module components. *It was revealed that with the advantages of low voltage, high power and high reliability, the Extreme N-type 700W series modules lead the new maritime scene, and interpret the leading edge of Trina Solar's N-type 700W series modules and the diversification of its application scenarios with its strength.
As early as 2021, Trina Solar began to study the new application scenario of offshore photovoltaics, starting from the characteristics of typical marine environments, establishing a complete module and material performance evaluation system, and achieving new breakthroughs in failure principle analysis and attenuation**, which is at the leading level in the industry. In May this year, Trina Solar's Extreme series modules received the TÜV Rheinland offshore PV certification, making it the first PV company in the world to pass this certification and an important milestone in the offshore application of PV products. As an outstanding representative of the Extreme series of modules, the Supreme n-type 700W series modules are based on the advanced 210 technology platform and n-type i-TOPCON cell technology, which brings greater opportunities for the development of offshore photovoltaics.
The Extreme N-type 700W+ module unlocks the offshore scene, and the better BOS performance proves the leading strength
Taking a domestic fishery-PV complementary project as an example, the results show that Trina Solar's 210-66 Extreme N-type 700W series modules can save 003—0.06 yuan watts.
In the offshore photovoltaic application scenario, the unobstructed vast sea area is more suitable for the layout of long array supports, the wind conditions in the open sea are complex, the water depth and waves are large, and the impact of ice floes in the northern sea area needs to be considered, so the design pile length and pile diameter of the pile foundation fixed project are longer, resulting in the basic materials and construction costs of offshore photovoltaic will be much higher than that of onshore photovoltaics. In addition, the marine environment has higher requirements for wind resistance, corrosion resistance, damp heat resistance, aging resistance and other materials such as pile foundations, floating bodies, and brackets. The results of the calculation show thatThe application of Trina Solar's N-type 700W series modules can effectively reduce the use of materials, and the cost advantage of BOS is more significant
Provide optimal component solutions according to local conditions
Offshore PV is mainly divided into two mainstream structural forms: fixed pile foundation and floating type. Depending on the installation method, water depth and offshore distance, Trina Solar has defined the corresponding module product solutions.
At present, Trina Solar has demonstrated and applied cases in both floating and pile-based fixed offshore PV. daysHesolar's ultra-high power modules of the 670W series have maintained efficient, stable and reliable operation after being tested by the marine demonstration of the country's first offshore floating photovoltaic demonstration baseIn the 2023 Offshore Photovoltaic System High-Quality Development Forum and the unveiling ceremony of the CPVT &CIMC Solar Co-construction Offshore Photovoltaic Demonstration Base, it was awarded the "Commemorative Certificate of Safe Operation". On the beachfront beach in Haiyan Town, Taishan City, Guangdong Province, the 100MW "Fishery and PV Complementation" project uses Trina Solar's Extreme series modules, bringing customers more value with the core advantages of "four highs and one low" of high power, high efficiency, high reliability, high power generation and low LCOE.
Fearless of the "three highs and three strongs", the supreme module leads the offshore photovoltaic scene with ultra-high reliability
In view of the characteristics of the marine environment of "three highs and three strongs" (high temperature, high humidity, high salt spray, strong wind, strong waves, and heavy precipitation), photovoltaic modules need to have better coping conditions in terms of load, salt spray, PID, and DH. Trina Solar, together with a third-party testing organization, conducted a series of rigorous tests on the modulesThe results show that Trina Solar Extreme modules maintain highly reliable load performance under extreme climatic conditionsUnder the Offshore PV module power attenuation (Arrhenius) model, the 30-year attenuation rate of outdoor PID is within 3%.
At the same time, the reliability of materials such as component connections is critical. Trina Solar has established a comprehensive design specification, process control and reliability evaluation system for module connectors. The reliability test data of component-related components under the conditions of high-temperature cooking, high-temperature reverse bias, current aging, temperature cycling, on-off and damp heat are all at the industry-leading level. Taking the junction box as an example, frequent sea breeze impact may cause loosening of the junction box, cables and connector connections, but Trina Solar's Extreme module has no abnormality in appearance and power generation performance after more than 200,000 connector shaking tests. In response to the problem of seawater erosion of junction boxes and connectors caused by waves and heavy precipitation, Trina Solar also designed IPX6 (strong water spray), IPX8 (continuous diving) and long-term seawater immersion experiments after aging to verify the excellent waterproof performance of the junction boxes.
Looking ahead, Trina Solar will continue to uphold the mission of "using solar energy for the benefit of all mankind" and the core values of "customer-centric", and contribute more to the development of offshore PV and the global clean energy transition.
