  •  Sunlight is diverse (4+ / 0-)

    There is no 'economy of scale' in solar radiation.  the solar energy that strikes the earth is about 946 watts per hour per square meter (perpendicular to the rays).  There is NO place on earth where it is more than that -- it's the same on your house top as it is in the desert.  So building a large solar power plant doesn't make a whole lot of sense for a power company.
    What seems to make sense is a distributed collector array -- solar panels on every roof with battery storage in every garage -- and service contracts to maintain the equipment for the home-owner.  I don't know why power companies haven't picked up on what amounts to an almost free source of revenue (service contracts).  

    •  Actually (4+ / 0-)

      there are significan economies of scale in the construction and permitting, which is why many (but not all) developers look to do utility scale solar.

      homes to put solar on roofs, there is a great deal of cost associated with selecting, purchasing, contracting and installation that is lower for large scale projects.

    •  Different method of collection (2+ / 0-)

      This isn't passive collection via PV panels.  The plants out in the desert are massive things that concentrate sunlight to create steam to turn turbines.

      But I am with you -- if we covered even 1/10 of rooftops in this country with PV panels, we'd have all the energy we need for everything.

      More solar energy hits the surface of this planet on any given day than will be burned in the entire history of all fossil fuels combined.  Why are we not making more of an effort to harvest it?

      because they tend to be cloudless and to not have interfering structures to cast unwanted shadows.  Lots of places get less than "about 946 watts per hour per square meter" because of clouds.

        either from a DNI point of view or an economy of scale POV.

        Remotely sited solar loses as much or more in transmission as is gained by slightly higher insolation.  Transmission is costly ($10 + million/mile), highly inefficient and slow to permit and build.  The use of sulfur hexafluoride or SF6 in power transformers and circuit breakers contributes to GHG emissions as does digging up highly calcified (and carbon sequestering) desert soils.   We don't have time to repeat the same old energy mistakes folks.  Distributed point of use solar is cheaper, faster and smarter.  More at: http://solardoneright.org/...
