wind and utility-scale solar projects generated a record 17% of U. electricity in 2025—an enormous jump from their share of less than 1% in 2005 (Energy Information Administration).
National Solar is a world leader in the origination, design, construction, financing and operation of renewable energy systems for the utility energy marketplace.
Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025.
NLR has developed a cyber-physical test bed to investigate the complex interactions among emerging microgrid technologies such as grid-interactive power sources, control systems, and communication platforms and bandwidths.
NLR maintains a chart of the highest confirmed conversion efficiencies for research cells for a range of photovoltaic technologies, plotted from 1976 to the present.
With DER management systems (DERMS), utilities can apply the capabilities of flexible demand-side energy resources and manage diverse and dispersed DERs, both individually and in aggregate.
TERMS, DEFINITIONS AND SYMBOLS1 ScopeThis Technical Specification deals with the terms, definitions and symbols from national and international solar photovoltaic standards and relevant documents used within the fiel of solar photovoltaic (PV) energy systems.
This map provides information about all of the solar photovoltaic (PV) manufacturing facilities in the United States and how they contribute to the solar supply chain.
Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop estimates of the performance of potential PV installations.
In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh.
Significant advances in battery energy storage technologies have occurred in the last 10 years, leading to energy density increases and battery pack cost decreases of approximately 85%, reaching $143/kWh in 2020. 4 Despite these advances, domestic growth and onshoring of cell and pack.
Marking five years since its overall completion on Saturday, the Three Gorges project has solidified its role as a multi-functional backbone of China's Yangtze River management, delivering extensive benefits in flood control, power generation, water supply, and shipping.
