 Current tax incentives aimed at encouraging users to install solar
technologies fail to reward actual energy produced, said the authors
of the report, published by the Massachusetts Institute of
Technology Energy Initiative, which promotes adoption of renewable
energy.
Solar energy received approximately $5.3 billion in federal support
in the 2013 fiscal year, up from about $1.1 billion in 2010,
according to the U.S. Energy Information Administration.
Most federal tax credits for solar are to expire at the end of 2016.
"Ideally ... rather than subsidize investment, we would subsidize
production, so you receive the greatest benefit for each
kilowatt-hour of solar energy you generate," said Francis
O'Sullivan, a co-author of the report, called "The Future of Solar
Energy."
Solar industry subsidies have long been politically controversial,
becoming even more so after the 2011 bankruptcy of Solyndra, a
California solar panel manufacturer that received $535 million in
federal loan guarantees from the Obama administration.
 The MIT Energy Initiative report also said federal funding for solar
research and development should prioritize emerging technologies
that could have a transformative impact on costs. Research on
incremental improvements to existing technology is already well
funded by commercial firms, the report's authors said.
"Smart people in industry have every incentive to work on that, but
they don't really have any incentive to look forward 20 years, and
we think that's the DOE's (Department of Energy's) job," said
Richard Schmalensee, a professor at MIT's Sloan School of Management
who chaired the study.

Improved technology at lower prices has pushed growth in solar
capacity, with the amount of U.S. electricity generated by solar
technologies up 82 percent between February 2014 and February 2015,
according to the EIA.
Still, solar energy accounted for just 0.4 percent of U.S.
electricity generation in 2014.
"The real question is, 'Can solar help us deal with climate?'"
Schmalensee said. "That means solar at scale in the decades ahead."
The report also said regulations and pricing systems should adjust
to anticipate greater solar penetration. That would include ensuring
residential and other solar generators pay their fair share of costs
to the overall system, such as maintaining electrical wires.
