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.
Solar photovoltaic technology will maintain its position as the world's most cost-competitive power generation source through 2025, with single-axis tracker systems in the Middle East and Africa leading at US$37/Megawatt hour (MWh).
Renewable Energy Has Achieved Cost Parity: Utility-scale solar ($28-117/MWh) and onshore wind ($23-139/MWh) now consistently outcompete fossil fuels, with coal costing $68-166/MWh and natural gas $77-130/MWh, making renewables the most economical choice for new electricity.
Cost-benefit analysis offers a structured approach to measure the viability and profitability of solar investments by comparing the initial costs with long-term benefits, such as reduced energy bills, tax incentives, and environmental impacts.
Across the EU, photovoltaics surpassed coal-fired power generation for the first time in 2025. Wind power was the strongest net electricity producer in Germany, although production was 3. 2 percent lower than in the previous year at 132 terawatt hours (TWh) due to poorer wind.
This guide reviews five leading rooftop solar panel kits chosen for American homes, RVs, boats, and off-grid setups. Each option leverages advanced N-Type technology, anti-shading features, and space-saving designs to maximize usable output while minimizing hot spots and wear.
A portable solar power system is a self-contained energy solution that combines solar panels, battery storage, and power conversion technology in a mobile, easy-to-use package.
This is a type of solar PV system that involves the generation of electricity using solar panels mounted on the rooftops of residential, commercial or industrial buildings or structures. The rooftop systems include solar modules, inverters, electrical accessories.
Tulsa-based natural gas pipeline giant Williams said Thursday it is entering the solar energy business. The midstreamer, whose pipeline network spans more than 30,000 miles, plans to develop a series of solar photovoltaic farms to help power its gas transmission and processing.
