This report summarizes the latest statistics on solar power capacity by state and highlights the top U.S. states in solar power generation.
It is one of the fastest-growing renewable energy technologies and is playing an increasingly important role in the global energy transformation. The total installed capacity of solar PV reached 1 865 GW
Installed solar energy capacity Cumulative installed solar capacity, measured in gigawatts (GW).
A comparison of the solar power status among countries and territories has been provided, considering their concentrated solar power and PV installed capacities for each continent.
Solar and wind accounted for 91% of new US electrical generating capacity added in the H1 2025, according to data just released by the Federal Energy Regulatory Commission (FERC),
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
Solar accounted for 58% of all new electricity-generating capacity added to the US grid through the third quarter of 2025, with more than 30 GW installed. Solar and storage, combined,
Solar, wind, and batteries are set to supply virtually all net new US generating capacity in 2026, according to the latest EIA data.
Installed solar capacity quantifies the maximum electrical power that all solar photovoltaic (PV) and concentrated solar power (CSP) systems combined can generate at any given moment.
Scelto Energy Africa is a leading energy storage equipment manufacturer and integrator based in South Africa, serving the African market. We specialize in lithium-ion batteries for residential, commercial and industrial use, system-level battery management systems (BMS) for optimal performance and safety, energy conversion systems (PCS) for efficient power flow, energy storage battery system cabinets with integrated monitoring, communication cabinets for telecom and data centres, commercial & industrial energy storage cabinets for factories and warehouses, integrated PV-storage systems for seamless solar plus storage operation, distributed energy resources for microgrids and off-grid applications, and deep discharge battery technology for extended cycling. As a full-service provider, we also offer 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 Africa.
Our modular energy storage portfolio ranges from compact lithium-ion 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 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, integrated PV-storage or large zero‑carbon parks, our products feature advanced thermal management, deep discharge cycling, and compliance with African and international standards. We also provide professional energy storage system installation and after‑sales support across Africa.
