US: the once and future PV market

Once upon a time, the global PV market was a US market.

Some 60 years ago, AT&T created the PV market. The industry was sustained during the 60s from military and space applications.

This is not just PV. Meanwhile, during the 1970s energy crisis solar hot water became mainstream (at least temporarily) as Californians replaced water heaters and pool heaters with rooftop collectors. In the 1980s, California created SEGS, the largest facility in the world that once comprised more than 90% of the world’s capacity.

As any reader of this blog knows, the German feed-in-tariff (and similar subsidies in selected other EU countries) has created huge growth and shifted the bulk of the global PV demand to Europe. In 2010, 80+% of the global demand was in Europe — and of that Germany was by far the largest with 8+ GW of capacity added in 2010.

Wednesday at the SolarTech 2011 Solar Leadership Summit, Shayle Kann of GTM Research talked about the growth of US PV demand, based on a state-by-state survey it did in cooperation with SEIA.

First off, Kann said "There is really no such thing as a US market. There’s a loose collection of 50 state markets” or even 3000-utility-specific markets.

In 2010, the US installation of PV reached 878 MW (volts DC, i.e. pre-inverter), up from 290 MW in 2008 and 435 MW in 2009. While US growth has been explosive, so has the US share of the global market , flat at 5-6% over the past six years.

However, GTM is expecting the US market growth will now outpace global sales — continuing to double annually, with global growth only 17-18% per annum. If these trends hold, the US share of the global market could triple to 16% by 2015. With European growth slowing, PV companies are seeking growth elsewhere and Kann said they're targeting the US for that growth.

The top 10 states account for about 85% of the US market. According Kann's data, 2010 was the first year that California did not garner for the majority of the US market: from 50.3% down to 29.5%. NJ remains number two (up to 15.6%), but Nevada (6.9%) and Arizona (6.2%) leapfrogged Colorado (6.2%) within the top 5. Florida fell both in absolute and relative terms (from 8.3% to 4.0%).

One key element of growth will be utility scale systems: 6.4 gigawatts (7 years of demand) of utility scale capacity is contracted — with all of that online by 2015. Another 13.6 GW are announced but do not have a signed PPA.

Interestingly, US manufacturing (per GTM numbers) has remained constant at around 38-40% of the market. While Chinese makers have gained share, it’s been at the expense of Japanese makers rather than US ones.

Still, PV remains a drop in the bucket for US electricity generation: PV to date totals 2 GW peak capacity, whereas 50 US power plants (mostly hydro and nuke) have 2GW capacity each. So, as Kann noted, it will be a while before PV actually has a meaningful impact on US electricity generation.
