    Solar Power Much Cheaper to Produce Than Most Analysts Realize, Study Finds
    ScienceDaily (Dec. 7, 2011) — The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen's University.
    Solar power much cheaper to produce than most analysts realize, study finds

    Many analysts project a higher cost for solar photovoltaic energy because they don't consider recent technological advancements and price reductions," says Joshua Pearce, Adjunct Professor, Department of Mechanical and Materials Engineering. "Older models for determining solar photovoltaic energy costs are too conservative."

    Dr. Pearce believes solar photovoltaic systems are near the "tipping point" where they can produce energy for about the same price other traditional sources of energy.

    Good news assuming that the numbers are right.

    When does this good news scale up to truly cheaper solar power?

    Advances are always good,just wondering how the will make it work at night,and when it clouds over for weeks at a time.

    Batteries and inverters are expensive high maintenance and not very green,but then there are never any free lunches are there.

    Chickenwing, read a little about grid parrallel solar. You put your excess on the grid for credit, and use power off the grid at night. A win-win for everybody.

    Who pays for the maintenance, the idling time, the personnel for the nightime PRIMARY sources that just sit there all day while the sun is out? This is NEVER calculated in the true cost of solar energy. But the need to have a PRIMARY RELIABLE 24/7 source ready to back-up solar generation deficiencies is a REAL cost that gets ignored in all of these analyses.

    The fact that people get paid for deciding to be energy producing moguls (a losing proposition in most cases even with the solar panel market temporarally crashed) is a political artifact, not an indication of an actual generation problem getting solved..

    That's because it's irrelevant. The cost of solar power is calculated as the cost of all equipment initial purchases plus maintenance divided by lifetime kilowatts produced. Just as all other forms of energy production are calculated the same way, plus fuel costs if any.

    No "nighttime primary sources" are needed; all complete solar generations systems whether large-scale commercial or home rooftop, include storage batteries to provide power during times when the sun's not out. The capacity during generation times needs to be calculated with that in mind, not just current use -- and it always is.

    (Home systems aren't always "complete" and sometimes rely on net-metering rather than on-site storage; however, complete solar systems exist for use off the grid and there the principle applies.)

    Most analysts are wrong and professor Pierce is right? Prof Pierce of Ontario, Canada is hardly an impartial observor or an economic expert. He is in the business , duh, of promoting solar technology. Even if the crap was as relatively inexpensive to manufacture as Prof Pierce imagines it still doesn't work efficiently enough to make it a viable source of electricity. You need a freaking football field of the stuff to fully energize a modern house.

    CSI CS6P-235PX 235W Solar Panel

    Panels for under $1.50 a watt. About 20 sq ft per panel, so a 24 panel installation, $7200, would give you an installation of 5 kw, covering 480 sq ft. Hardly a football field, and would handily power a normal home.

    As usual, Whitey, you are full of shit.

    Your numbers don't coincide. In 2010 cost = $7.61 and in 2007 cost = $4.16. There is no reduction as stated as claimed based on 2009 claim, these prior 2010 vs 2007 states prices has increased by 22.3% not the 70% in 2009 reduction claimed in your report/find.

    Well Z, you can pay $7.61 if you want, but for the more informed, you can get panels for under a $1 a watt, if you buy in bulk. This can be, and is being done, by people forming solar co-ops. And those with some reasonable amount of skill can install their own and keep there costs down to the point of a five year payback. Shorter payback yet, considering how much the utilities keep jacking up the price every year.
