Comments for Progression of US Cities Reaching Solar Grid Parity at http://www.ecogeek.org , comment 1 to 3 out of 3 comments http://www.ecogeek.org Wed, 22 May 2013 08:00:08 +0100 FeedCreator 1.7.3 http://www.ecogeek.org/solar-power/3671-progression-of-us-cities-reaching-solar-grid-parit#comment-45403 Assumptions appear to be incongruent. A comparison based on either lifetime $/W or on installed $/W of both dirty energy and PV would be more appropriate. Also, if the analysis would take away tax breaks, discounts, depreciation and subsidies (for both dirty energy and PV) the results would definitely show that PV has already far exceeded "parity" in most areas of the US. - Robert Smith Thu, 12 Jan 2012 15:06:17 +0100 http://www.ecogeek.org/solar-power/3671-progression-of-us-cities-reaching-solar-grid-parit#comment-45357 Solar module prices are now low enough for the cheapest installations to be reaching grid parity here in Australia. (The cheapest installations are usually on large flat roofs or on the ground.) It will be interesting to see how rapidly PV use expands over the next few years here. High levels of sunshine and high retail electricity prices mean that Australia and Hawaii can be test cases for what happens when grid parity is reached. - Ronald Brak Fri, 06 Jan 2012 17:04:27 +0100 http://www.ecogeek.org/solar-power/3671-progression-of-us-cities-reaching-solar-grid-parit#comment-45341 Funny thing about assumptions... they are frequently awry. Today (1/5/2012), there was a PBS radio new program on how the cost of solar was up (due to decreasing gov't subsidies as more people install) and the cost of natural gas generated electricity was down... about doubling the recuperation time for home panels, to about 17 years. The solar owner interviewed said that is the lifespan of his equipment..., and the cost does not include repairs (as needed). - Doc Rings Thu, 05 Jan 2012 12:36:09 +0100
