Led by China, the solar power industry will grow at a CAGR of 8.3 percent – from 37.5 GWp in 2013 to 65.6 GWp in 2019 – but emerging trade disputes involving the Asian giant, as much as global policies, cast a shadow over short-term prospects, according to Lux Research.
China became the biggest solar energy market in the world with 11.8 GWp installations in 2013, and has been key to faster-than-expected global recovery. Since the competitive bankruptcy-ridden cost environment of 2012, module supplier margins have increased, with most Tier-1 suppliers topping 10 percent toward the end of 2013 and 15 percent in the first quarter of 2014.
Growth is fastest in the Americas. At a CAGR of 16.3 percent, the Americas will be the fastest-growing region in the world as its new installations market nearly triples from 5.3 GWp in 2013 to 15.4 GWp in 2019.
The U.S. will pace the rest of the Americas, growing from 4.7 GWp to 11.7 GWp but South America will grow 10-fold to 2.5 GWp in 2019. The Asia-Pacific region will grow at a lower 8.2 percent CAGR but will account for over 50 percent of global demand, led by China, Japan and other emerging markets.
Cost cuts will be sustained. With cost cuts critical to the sustained growth of the industry, incremental increases in efficiency are on course from technologies such as passivated emitter rear contact (PERC), heterojunction with intrinsic layer (HIT) and selective emitter (SE). System costs will drop by between $0.36/Wp for utility-scale and $0.60/Wp for residential by 2019. This will translate to a 20 percent cut in total system costs.
X-Si remains technology of choice. Crystalline silicon will dominate the solar market through 2019 even though other module technologies such as copper iridium gallium diselenide, copper zinc tinc sulfide, cadmium telluride and thin, flexible, epitaxial silicon have the potential to become major threats in the future. X-Si, with an 84.6 percent market share, will grow from 31.6 GWp in 2013 to 55.7 GWp in 2019, growing at a CAGR of 8.45 percent. CdTe and CIGS will be a distant second – growing to 4.8 GWp and 4.2 GWp, respectively, in 2019.
