IEA PVPS has released its latest Trends in Photovoltaic Applications 2025 report, revealing that the world's cumulative installed PV capacity surpassed 2 260 GW by the end of 2024, marking a 29% year-on-year increase.
In terms of cost-effectiveness, C-shaped steel is more affordable than aluminum alloy brackets, and its installation costs are lower, making it ideal for large-scale projects to reduce costs.
Keeping panels cool boosts energy output, which is why ventilation behind panels and quality insulation within the building work hand in hand. Insulation helps maintain indoor temperatures, reducing the demand for cooling or heating, which lowers overall energy use.
