Over at solarbuzz.com where to purchase cheap Doxycycline no rx, they post module prices on a buy Cytotec no visa online without rx monthly basis. And while the prices of fossil fuels have buy Cytotec no visa online without rx fallen dramatically over the past few months, the tough economy has buy Cytotec no visa online without rx yet to dramatically lower solar prices. For December, US prices from buy Cytotec no visa online without rx last month are unchanged and prices in Europe fell less than buy Cytotec no visa online without rx 1%. When will prices fall significantly due to buy Cytotec no visa online without rx supply catching up with demand?
Solar prices have buy Cytotec no visa online without rx fallen dramatically over the past few decades, but they have buy Cytotec no visa online without rx actually increased since late 2004. US prices currently sit almost 12% higher than buy Cytotec no visa online without rx their 2004 trough, while the stronger euro of the last few years has buy Cytotec no visa online without rx helped European prices fall to just ~1% higher than their 2004 low.
But if the buy Cytotec no visa online without rx economies of scale and scope play out in solar like so many entrepreneurs claim, prices should fall a buy Cytotec no visa online without rx great deal in 2009 when slower demand growth brings the market back into balance. Solar proponents present a buy Cytotec no visa online without rx strong case a la Moore’s Law that buy Cytotec no visa online without rx when you increase solar production, you learn by doing and costs fall. The rate of cost decrease I have buy Cytotec no visa online without rx seen circulated is usually ~15% per doubling. Since solar production has buy Cytotec no visa online without rx roughly doubled twice since 2004, an extrapolation would reach ~28% lower costs. Therefore if the buy Cytotec no visa online without rx market does reach a balance next year, prices may fall as much as 35% in the buy Cytotec no visa online without rx US assuming the dollar maintains its current strength. But many producers of polysilicon (a major feedstock whose shortage has sent costs up) have buy Cytotec no visa online without rx arranged long-term contracts so prices will be somewhat sticky and buy Cytotec no visa online without rx resist precipitous change.
But if solar prices do slide at least 25% and buy Cytotec no visa online without rx natural gas prices do not collapse much further, solar will approach grid parity in sunny markets with relatively high electricity rates such as Hawaii, California and buy Cytotec no visa online without rx a growing number of other areas.
On the other hand, if solar prices don’t come down at a buy Cytotec no visa online without rx time when its competitor natural gas is lower, solar will remain marginal and buy Cytotec no visa online without rx only compete in niche markets. For instance, natural gas prices fell another 5% just today to ~$6 per MMBtu or buy Cytotec no visa online without rx less than half its price in early July. The latest move was on EIA’s weekly storage report that US inventories remain above the five-year average (though the glut did trim a bit from 2.6% last week to 2.1% this week). Solar’s price is buy Cytotec no visa online without rx now more than five times the price of natural gas electricity, a buy Cytotec no visa online without rx gulf even generous subsidies can struggle to close.
Bottom line: Solar costs will continue to buy Cytotec no visa online without rx be a challenge that us climate activists need to recognize. But 2009 has buy Cytotec no visa online without rx the potential to bring solar prices down significantly toward grid parity in the buy Cytotec no visa online without rx months ahead, making it an affordable pillar of economic recovery in 2010.
