Solar Power

Kuldip Sidhu
Hello ,

Is there anybody has keen interest in Solar Power which perhaps less talked about because of the Cold weather.

    Kuldip Sidhu:

    Hello All,

    Yes I am based in U.K. My Equipment is designed for U.K as well as for overseas Market. My view is one cannn’t generate more than 2KW power on a 4 Bedroom Detached House. If someone has different opinion I would love to hear about it. I am very happy that I am getting lot of feed back from you. Keep it up.





    That all depends on your roof.  On my 3-bed semi, I have 18 panels, rated at 3.4kW peak.  Those panels are now obsolete - new ones would generate more like 4kW peak.  But I have a nice simple roof with plenty of space for panels, and all facing just East of South.

    Of course, as with all energy issues there's the question of whether solar panels offer a "whole life" greenhouse gas reduction, i.e do they take more fossil fuel energy to build than they save, this thread has just made me look this up and there's a nice article here http://www.nature.com/articles/ncomms13728 that suggests that yes, they have now passed that break even point through advances in technology and larger scale manufacturing.


    There are those who dismiss solar panels and wind power as "irrelevant", my feeling is that with the rise of electric cars they may become very relevant!


    Cheers,

    Andy




     

    Andy, this is a slightly older review on the energy balance of solar PV.  The conclusion was that anywhere north of Spain is unlikely to give a real payback.

    Your last comment is thought provoking enlightened

    Interesting article, particularly where it points out that because this is such a political football it's fantastically hard to get to the truth of the matter. Which is very frustrating and annoying.


    I went a fascinating LN talk a few years ago about a proposed project for massive solar thermal generators in North Africa to be connected to the UK (and the rest of Europe) by, IIRC, a huge DC link. ("Desertec"?) Again others will know of this project, it's been around for a while. From the engineering point of view seems a very interesting idea, although tthe sclae of the distribtuon network seems a big issue - but I'm no expert here by a long way. Politically has some challenges, although instinct says these should be no worse than buying gas from Russia.


    I think Rule 1 of anything to do with energy is this: There are no easy answers! But some very interesting opportunities.


    Cheers, Andy

    Andy,


    As you say climate change and renewables is so politically charged and polarised that it is very difficult to get credible information and data.


    Previously I tried to get information on the size of the foundations used for wind turbines, I realise that they are partially dependant on location and ground conditions, but there is almost nothing publically available. I eventually found a research proposal from the USA DoE with some data. I was trying to compare the excavation and concrete requirements for Hinkley Point C with the requirements for an equivalent number of wind turbines assuming 20% capacity factor. The figures for the nuclear power station were readily available.

    It’s frustrating!


    Best regards
