What happens to solar panels and materials after their useful life? What role does recycling play in the lifecycle of photovoltaic (PV) systems? Is it possible to design PV in a “cradle to cradle” approach so that materials are designed with the purpose of being reused, upcycled, or recycled to a safe and useable material instead of ending up in landfills? From 2010 to the 2nd-quarter of 2015, the U.S. has cumulatively installed 19,884 MWdc of PV in the residential, non-residential, and utility markets Given the growth in solar installations over the last five years, exploring these questions is prudent for designing a more sustainable energy system.

Solar STAT Blog
This blog discusses state and local efforts to develop solar markets in the United States. With support from the Energy Department's SunShot Initiative, members of NREL's Solar Technical Assistance Team (STAT) author posts related to events, solar policy analysis, and technical assistance outcomes for the purpose of informing the market in a credible and timely fashion.

This series explains more about batteries and the power-to-energy ratios. This is the second part of a two-part series. Read part one of the series.
As solar and other renewable energy technologies become more mainstream, the public becomes more familiar with the language of photovoltaics (PV). Even if most people don't have a thorough understanding of how it works, homeowners with a PV system may know the difference between the rated capacity of the system (expressed in kilowatts) and the amount of electricity that the system actually produces (expressed in kilowatt-hours). Homeowners may be confident explaining their 5-kilowatt system produces about 7,000 kilowatt-hours per year.Continue reading

Surprise! It’s not wealthy enclaves or college towns but often small communities with solar farms leading the way.
Recent NREL research analyzed the installed solar capacity in municipalities across six states and found that the communities generating the most solar energy per capita are smaller communities with fewer but larger solar installations. In addition, the study found that these leading solar communities are generally at or below state averages in education attainment and income levels—dispelling a common perception that wealthy or highly educated communities generate more solar energy.Continue reading

Sunny San Diego welcomed state energy officials and their affiliates to the 2015 National Association of State Energy Officials (NASEO) annual meeting September 13-16. The theme was “Interconnected: Smart Energy Policies, Clean Energy Investments, and the Cloud.” As an affiliate, I had the opportunity to share information about state and local clean energy policies as well as the types of technical assistance the Solar Technical Assistance Team (STAT) provides to state-level decision makers. Several themes emerged from the whirlwind of presentations, discussions, and one-on-one conversations with participants. Continue reading

When Hurricane Sandy made landfall on the east coast of the United States, New Jersey was ranked second in the country for solar photovoltaic (PV) implementation—only behind California. However, when millions of New Jerseyans were without power after the storm, only two PV systems in the state were operational. Continue reading

Under U.S. law, individual states can evaluate and modify interconnection and net metering policies and regulations based on changes in technology. Due to the increasing complexity of new photovoltaic (PV) technologies, one of the most popular requests received by NREL's Solar Technical Assistance Team (STAT) is for help with understanding and evaluating solar interconnection and net metering policy options. Continue reading
