Eight Great Women in the Business and Science of Solar
It has been a long, long, long road for the global photovoltaic industry and its participants from its early days with few manufacturers and support primarily limited to oil companies looking for a feel-good business unit to what seemed like its overnight success in the mid-2000s. In 1977 the industry had 1.74 MWp of capacity to produce PV cells. At the end of 2017 the industry had 98 GWp of capacity to manufacture PV cells. [...]

The Solar Trade Case: It's Gonna Be President Trump's Decision!
Not much new surfaced at today's public hearing on the Section 201 trade case. Rather it was a reaffirmation by both sides of what they had previously stated in the two public hearings at the International Trade Commission.  The hearings started off with Governor McMaster of South Carolina and Senator Heinrich of New Mexico testifying against the imposition of any tariffs. There were no elected officials testifying on behalf of Suniva/Solar World.  [...]

Looking for New Solar Markets? Think Water.
So if solar won’t be growing in the United States, where should developers look for new markets? One place is in disaster relief. Yung Wong, engineering manager with WorldWater and Solar Technologies explained that when disaster hits, the first thing that the Red Cross and the military do is fly in water bottles. He said that the cost to transport water comes out to about $1.85 per gallon whereas his company can provide drinking water for just a few cents per gallon though a mobile self-sustai [...]

Clean Energy Leaders Fear Brutal Impact on Renewable Growth As US Tax Reform Takes Shape
In the early morning hours of Dec 2, lawmakers in the U.S. Senate passed their version of a tax reform bill. Unlike the version of the bill passed by the U.S. House of Representatives, the Senate bill makes no changes to the Investment Tax Credit (ITC) and the Production Tax Credit (PTC), on which wind and solar energy developers rely to help finance projects. However, the bill makes changes to the way corporations can use tax equity, in a provision called BEAT (base erosion and anti-abuse tax), [...]

Why the Bifurcation of an Industry’s Supply and Demand is Bad for Everyone
“Happy families are all alike; every unhappy family is unhappy in its own way,” Leo Tolstoy, Anna Karenina.  In the solar industry, strong markets are alike in that they have incentives, subsidies and/or mandates to drive growth and adoption but also a fair amount of political and economic risk and every weak or collapsing market is alike in that it no longer has incentives, subsidies and/or mandates to drive it and its political and/or economic risk has become a reality.

Massachusetts Opens RFP for the First 100 MW of “Smart” Solar
On November 13, utilities in Massachusetts announced that they would begin to accept bids pursuant to the new “Solar Massachusetts Renewable Target or SMART” program, which seeks to ultimately add up to 1,600 MW of solar capacity. The SMART program was voted into law in April and explained in great detail by Renewable Energy World contributor John Farrell in this post. Farrell likens the program to the California solar incentive and Germany’s long-expired Feed-in Tariffs, which kick starte [...]
