RatedPower’s 2025 Global Renewable Trends Report surveyed industry professionals and drew data from simulations of more than 45,000 solar projects using RatedPower’s site planning software. 48.3% of respondents to a survey of clean energy professionals say energy storage is a key area for growth through 2029, more than the 30.8% of respondents who highlighted the promise of solar power. The 2025 Global Renewable Trends Report has been published by RatedPower, a Spanish software company for large-scale solar energy projects owned by the Texas software company Enverus. The publication surveyed over 140 industry representatives and the report also includes RatedPower user statistics, which provide insight into the most popular design trends across the project design platforms 45,000+ sites. Energy storage and solar power top the list of most promising trends, while green hydrogen comes in third place, cited by 9.8% of respondents. The United States, China, Australia, Brazil and India are the countries with the greatest growth potential for renewable energy, according to industry experts, followed by Germany and Spain. Government support, strong economic incentives and favourable geographic locations were cited as key factors in their projected potential. Respondents again cited grid congestion and instability, as well as permitting and regulation, as their top concerns, just as they did in 2024, but the number of people citing these issues dropped by around 6% in each case for the 2025 edition of the report. Industry representatives said supportive policies, incentives and streamlined permitting processes could unlock the potential of battery energy storage systems, agrivoltaics, floating solar and offshore wind, and also discussed the impact that artificial intelligence, machine learning and digitalisation will have on the cleantech sector. Key facts Some 93.7% of respondents rated their confidence in the future of the industry at four or five out of five and 60.1% said grid congestion and instability was the critical challenge facing the renewable energy industry, down from 66.7% last year. RatedPower statistics indicate that hybrid clean energy plants, which combine more than one technology, accounted for between 11% and 28% of simulations run on the platform during the four quarters of last year. Bifacial modules were the solar panel of choice in over 91% of simulations, reaching a record high of 94.46% between October and December. Trina Solar, Jinko Solar, JA Solar, CSI Solar, and Longi Solar were the five most commonly used module manufacturers in RatedPower’s project simulations. Yingli Energy Development, Trina Solar, Jinko Solar, Emmvee Photovoltaic Power, and Reliance New Solar Energy were the manufacturers with the highest average rated panel power. More than 60% of RatedPower’s 2024 solar project simulations included single-phase inverters. That upward trend has been consistent over the past few years, but central inverters remain more popular in simulations of plants with a peak power of 100 MW or more. The most commonly used inverter manufacturers in the simulations were Sungrow, Huawei Technologies, SMA, Power Electronics, Gamesa Electric, Ingeteam and TMEIC. In the last quarter of last year, solar trackers accounted for about 60% of installations, compared with 38% for fixed-mount panels and 2% for east-west configuration modules. The preference for solar trackers has remained constant in recent years. Nextracker continued to lead the list of mounting system brands chosen on the RatedPower platform, followed by TrinaTracker and Array Technologies. Soltec and Gamechange Solar rounded out the top five. Fixed-mount panels were most common in China, Germany, the UK and Indonesia. Developers in Australia, Brazil, Chile, Colombia, Italy and the US preferred tracker panels. |
