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
