    Solar ... In the news 7th Jan 13 at 4:36 PM
    Hi All

    Thought it was about time we had a thread specifically to discuss relevant press articles relating to solar pv & thermal ..... so here goes ...

    First article ....

    "Over 300 small Chinese solar companies stopped operating in 2012"
    http://www.pv-tech.org/news/over_300_small_chinese_solar_companies_stopped_ope rating_in_2012_says_enf

    .... looks like a number of customers will be sitting on a pretty meaningless warranty, but the good news is that "Crystalline-based module prices stood at €0.68/Wp (US$0.92) in December 2011 but by December 2012 had fallen to just €0.46/Wp (US$0.60)." ....

    Hiya, not exactly news as this article is 10 months old. But it gives a lot of info, especially supply & demand curve economics in a very neat package.

    Also the PV install graph (near the bottom) is up to date.

    P.S.
    Pity Warren Buffet doesn't realise that solar farms are not as efficient as small sub 4kWp systems on roofs of houses

    I have no idea how the system works, but got the impression it wasn't aimed at private dwellings.

    My elder brother has lived in California(in one of the hottest regions) for many years and he doesn't know anyone who has Solar PV on their property. He has, like many others, solar thermal for his swimming pool.

    Hi

    Information for US solar incentives .... Federal & by state ....

    http://www.pvpower.com/SolarIncentives.html

    Interesting to note that despite the USA having been such a slow starter, California alone now has a similar installed capacity to the UK.

    Hi

    The issue isn't space available or population density (~2/3 the population on ~2/3 more land, that's a population density of around 40% of what we have) ..... it's simply the rate of increase from what it was when we were debating whether FiTs existed, or not, in the USA about a year or two back ....

    .... as for San Francisco, don't believe everything on TV - I spent quite some time around the Bay Area around 20 years ago, it seemed to be much colder and windier around SF itself with some early mist, but cross any of the bay bridges and move inland and the temperature and air clarity increases by the mile .... I've got the requisit pictures of the base of the Golden Gate shrouded in mist with the towers in gleaming sunshine, but needed to get up pretty early to get the best effects ....

    Not sure where 'don't believe everything on TV' came from, since I said more or less the same as you!

    I also worked there for a couple of years some years ago - a pleasant short trip was to head to Sam's Caff over the Golden Gate at Tiburon, to watch the fog roll in over the city, more or less as regular as clockwork.

    This a few months old but interesting nonetheless. HSBC has a strong far east presence so will have good contacts to know what is happening in China regarding the struggles of their solar producers. Goes along with the article in post 2 but its clearly not just the smaller producers that are struggling.

    We are still selling mostly Hyundai, and mostly the all black ones. They are quite a bit more than the teir 2 chinese silver framed polys but worth it IMO. We also sell Sunpower, the most expensive panel in the world, which comes with a 25 year product warranty, it's not all about price...
  • Energetic
    However, China has just connected its first domestic PV system and if their incetives work they could soak up all the extra production domestically.

    There is a theory in the industry that their government has had a plan to push production costs down by flooding the market to make their panels affordable domestically and also eliminating competition in the west. They have a proper plan there...

    The way technology advances, I wouldn't be surprised if some time in the future it might even be worth changing panels for more efficient ones anyway(financially especially), considering the 25 year (now 20 year) time line of FiTs. And even after the FiT stops being paid beyond that it may likely still be a viable thing to do the way electricity prices are going. There doesn't seem to be much evidence of solar panels failing common place so far.

    I can comment on consrtuction though, some of the cheaper chinese panels don't feel very robust and clearly haven't had as much time spent designing the frames or attention to detail in their manufacture.
