SEIA produces a variety of research and supporting resources for the solar industry, ranging from full reports to short factsheets. This data helps inform policymakers and business leaders alike on the current state of solar and where the industry is headed.
Why Are Residential PV Prices in Germany So Much Lower Than in the United States? A Scoping Analysis
This report looks at the reasons for cheaper PV systems in Germany comparing to the ones in the US.
Finance & Tax | Regulatory PolicyImplications of Wide-Area Geographic Diversity for Short- Term Variability of Solar Power
Worldwide interest in the deployment of photovoltaic generation (PV) is rapidly increasing. Operating experience with large PV plants, however, demonstrates that large, rapid changes in the output of PV plants are possible. Early studies of PV grid impacts suggested that short-term variability could be a potential limiting factor in deploying PV.
Rooftop SolarSupporting Solar Power in Renewables Portfolio Standards: Experience from the United States
Among the available options for encouraging the increased deployment of renewable electricity, renewables portfolio standards (RPS) have become increasingly popular. The RPS is a relatively new policy mechanism, however, and experience with its use is only beginning to emerge.

Installations of grid-connected photovoltaic (PV) systems in the United States have increased dramatically in recent years, growing from less than 20 MW in 2000 to nearly 500 MW at the end of 2007, a compound average annual growth rate of 59%.
Rooftop Solar | Finance & TaxUnderstanding Variability and Uncertainty of Photovoltaics for Integration with the Electric Power System
Data and analysis are needed to understand the variability of photovoltaic (PV) plants to avoid unnecessary barriers to the interconnection of PV. Several data sets show clouds can cause rapid changes in solar insolation. Smoothing of rapid ramps, however, occurs within PV plants. The degree of smoothing depends on plant size.
