The One Big Beautiful Bill Act (the OBBB) signed in July 2025, as well as subsequent guidance issued by the federal government, significantly rolled back the core tax incentives that clean energy projects have relied on since 2005. . There is a patchwork of federal, state, and local policies and regulations pertaining to renewable energy systems that impact your project development. State Solar Carve-Out Programs - Learn about which states. . Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. and across the country to establish supportive policy frameworks that allow solar to. . Solar photovoltaics (PV) is a very modular technology that can be manufactured in large plants, which creates economies of scale, but can also be deployed in very small quantities at a time. This month's "Solar Policy Spotlight" delves into these pivotal changes, highlighting new legislation, incentive programs, and regulatory adjustments designed to. .

The International Electrotechnical Commission (IEC) has created two main standards for solar panels: In Europe, these standards are called EN IEC 61215 and EN IEC 61730. . The UL 1703 standard for flat-plate photovoltaic modules and panels is being gradually replaced by UL 61730, which aligns more closely with international standards. Following an overview about the major IEC PV module certifications: The IEC61215 covers the parameters which are responsible for the aging of PV. . Support to the ongoing preparatory activities on the feasibility of applying the Ecodesign, EU Energy label, EU Ecolabel and Green Public Procurement (GPP) policy instruments to solar photovoltaic (PV) modules, inverters and PV systems. reliability, degradation and lifetime. Since PV is such a global industry it is critical that PV products be measured and qualified the same way everywhere in the world.
