Global Solar PV Pipeline well Crosses the 200 GW Mark

With an undeniable stir in United States solar investment tax credit (ITC) proposed last year, the global solar photovoltaic pipeline is now reported to surpass 200 gigawatts (GW). At a combined capacity of 110 GW, projects in the U.S., China and Brazil make up half of the current PV pipeline, according to IHS.

The biggest growth of the global solar pipeline has been in the United States, where 16 GW of new projects entered the pipeline in 2015; at the same time, 10 GW of tracked projects were installed or entered construction. As a result of the ITC extension announced in December 2015, the U.S. pipeline is now changing shape, according to the latest IHS Solar Deal Tracker.

“A large share of the planned projects is still immature, with developers scouting for tenders and other opportunities to sign power-purchase agreements,” said Josefin Berg senior analyst for IHS Technology. “The previous panic to complete project phases ahead of schedule has reverted to a development pipeline responding to demand and contract fulfilment.”

Early-stage projects that tussled to complete development to match the completion prior to the previous deadline at the end of 2016, seem to have to get sigh of relief, as they do not need to enter construction before 2019 to benefit from the 30 percent credit.

“We expected to see some hectic activity from late-coming developers in 2016; however after the ITC extension, developers have calmed down,” said Christine Beadle, senior analyst at IHS Technology.

On the opposite end of the global spectrum is the United Kingdom, where the PV pipeline of pre-construction projects decreased by more than 4 GW in 2015. Projects continue to be built; however, few new projects have started development, because of the looming expiration of the Renewable Obligation Certificates (ROC) scheme in April 2016.

Economies of scale, and an inclination for oversized projects, are expected to increase system sizes. Two thirds of the global PV pipeline capacity is projects larger than 50 MW. Developers in both the United States and China target economies of scale by implementing large projects in areas with abundant land.

The oversizing of module capacity in relation to the output inverter capacity also raises total system sizes. In the United States, IHS tracks projects where the module capacity is up to 40 percent higher than the inverters.

“Among the markets with the largest pipelines, only Brazil prefers the more modest system size of 30 megawatts, as a result of regulation; however, Brazilian developers are bundling projects to reduce costs,” Berg said.
