Solar Beyond Grid Parity

Tickers in this article: LOW STP

NEW YORK (TheStreet) -- Adapting to abundance can be as tough as adapting to shortage.

When I left Houston, on June 1, 1981, the economy was riding high on $50/barrel oil. There were construction cranes everywhere along I-610, with billboards advertising health treatments and new condos.

Driving through around Christmas of 1984, I saw a completely different scene. Houston was in depression. Potholes filled the highway, and billboards now advertised churches or stood unrented. The sour smell of broken dreams hung everywhere.

Back at my new home in Atlanta, these were happy days. Atlanta is a trading center, and trade was booming. The decade-long real estate recession that began in 1974, just as Houston took off, had finally ended. It was truly morning in America. Just not in Texas.

I thought about those scenes on Friday after looking at a GTM Research report showing the manufactured cost of solar panels is going down even faster than expected, and could reach 36 cents/watt by 2017.

This led me to a map produced by the Institute for Local Self Reliance a few months ago, showing the market impact of various prices for installed solar panels. (Manufactured cost is one thing. What you buy is the installed cost.) The map showed average installed prices of $3.72/watt for 2013, and a fairly small market.

But I had just called a friend who's in the business, asking about his own bids on slightly larger projects, the kind that can be installed on convention centers or next to factory buildings. What price was he quoting for installed panels? I asked. The answer came back quickly, about $2.50/watt -- and he wasn't the winning bidder.

Plug that price into the ILSR map and you get a vastly different picture. At that price Georgia could sustain a market of almost 6.3 Gwatt. Grid parity would have been achieved in all but four to six states.

None of this assumes big breakthroughs in technology. The GTM report indicates costs will be cut, incrementally, in several areas to reach that 36 cent/watt price.

Yet, breakthroughs are coming.

Stuart Wenham, former chief technology officer for Suntech Power , one of the Chinese companies blown out in the recent market shake-out, told the Sydney Morning Herald he has found a way to cover up defects in silicon using hydrogen atoms, which will allow low-quality silicon wafers to perform like high-quality wafers and raise efficiency to as much as 23%.
