NECA 417-2019, Recommended Practice for Designing, Installing, Operating, and Maintaining Microgrids is the latest revision in the National Electrical Installation Standards (NEIS®) series published by the National Electrical Contractors Association (NECA).
September 2025 brought a wave of policy changes impacting the U. solar industry, from federal tax credit rules to state-level program expansions. Solar developers, manufacturers, and investors are now adjusting to new regulatory realities that will shape project economics.
A proposed 250-megawatt battery storage installation in Ottawa's rural west won a resounding vote of confidence Wednesday as Ottawa City Council approved a municipal support resolution (MSR) for the project on a 20-3 vote.
In 2025, wind power generated 464,000 GWh of electricity, 3% more than in 2024. Electricity generation from utility-scale solar has increased every year since 2006.
This paper examines the development and implementation of a communication structure for battery energy storage systems based on the standard IEC 61850 to ensure efficient and reliable operation.
While we don't expect a dramatic drop in pricing, there are opportunities to lower costs and increase homeowners' savings. After the passage of the One Big Beautiful Bill (OBBB), demand for solar exceeded the available supply of installation capacity, which drove prices up.
The 2024 Edition of Standards for the Photovoltaic Manufacturing Industry mandated reliability testing for mounting systems, addressing concerns that 35% of existing products failed fatigue life requirements. These reforms have accelerated technological innovation.
In 2025, standard residential solar panels produce between 390-500 watts of power, with high-efficiency models reaching 500+ watts. However, the actual energy output depends on multiple factors including your location, roof orientation, weather conditions, and system design.
Programs like the federal solar tax credit, state-level solar panel rebates, and utility-based solar subsidies have made it easier for homeowners to go solar and save on energy bills.
