Globally, renewable power capacity is projected to increase almost 4 600 GW between 2025 and 2030 – double the deployment of the previous five years (2019-2024). Growth in utility-scale and distributed
This report summarizes the latest statistics on solar power capacity by state and highlights the top U.S. states in solar power generation.
Installed solar energy capacity Cumulative installed solar capacity, measured in gigawatts (GW).
Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for
Utility-scale solar capacity reached 128.6 GW in March 2025, growing from 96.9 GW in March 2024, while small-scale solar, projects of 1 MW or less, reached 55.7 GW in March 2025,
In 2024, generators added a record 30 GW of utility-scale solar to the U.S. grid, accounting for 61% of capacity additions last year. We expect this trend will continue in 2025, with 32.5 GW of new utility
Capacity is not the same as electricity generation. Power plants have a capacity to produce a certain amount of power during a given time, but if they are taken offline (i.e. for
Data and analysis including a list of solar power in every country in the world, countries with the most solar power, and countries that generate the highest percentage of their electricity from solar power.
Solar is the leading resource for permitted plants, accounting for more than 70% of the 78,039 MW of permitted generation capacity. Wind and natural gas account for another quarter of capacity in this
Data and analysis including a list of solar power in every country in
Solar, in line with the previous year, accounted for the largest share of the global total, with a capacity of 1 865 GW. Renewable hydropower1 and wind energy accounted for most of the remainder, with total
GreenVolt Home Energy is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in wall-mounted energy storage batteries, power distribution cabinets, generation-storage integration, hybrid inverters (PV & storage all-in-one), communication battery cabinets with IP54 protection, grid-forming energy storage, PV storage power plants, residential all-in-one storage, and VPP-ready systems. As a full‑service energy storage equipment manufacturer, we also provide containerised BESS, modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for residential, commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact wall-mounted energy storage batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication battery cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation. Whether for off‑grid power systems, backup emergency power, PV+storage integration or large zero‑carbon parks, our products feature advanced thermal management, PCS and EMS integration, deep discharge cycling, and compliance with European and international standards. We also provide professional energy storage system installation and after‑sales support across Europe.
