View Full Version : Here comes the sun: the cost of solar energy is crashing down

While attention has been focused on the Government’s overblown plans for expanding windpower, something extraordinary has been happening to solar energy. The prices of solar photovoltaic (pv) panels have been plummeting, wrong-footing even proponents of renewable energy.

In just the last two years, says a new report by the blue-chip Ernst and Young the average one-off installation price of pv panels has plunged from about £1.25 per watt of generating capacity to less than 95p. And in another two, it predicts, it will have crashed again to little more than 60p, which would mean that costs had halved in just four years.

Another estimate, by HIS iSuppli Market Intelligence is even more bullish, reckoning that the halving will have taken place by the end of next year.

And the Silicon-Valley-based Applied Materials reckons that by the end of this year producing electricity from the sun will cost the same as buying it from the grid in 18 countries – including Italy, Spain and Brazil – as well as its home state of California. That critical take-off point could come as soon as 2016 in the UK, but is unlikely to be later than 2019. By 2020, Applied Materials adds, more than 98 per cent of the world’s population will “have access to solar power at the sane cost as current residential power”.

All of which makes the official Committee on Climate Change –which last month concluded that solar power was too expensive to warrant attention in the short term, and instead backed nuclear energy as the cheapest low carbon source – look distinctly behind the times.

I love my Micky Mouse solar pannels from Harbor freight.....it puts out a hell of a lot more energy than what I am using so that I will add another 12v battery........my main solar panel, 120w, is now 12 years old and still working great and to that one I will also add another 12v battery........at $75.00 for the deep cycle batteries it is a pretty good deal.

WTSHTF I then will use my 5,000w generator one hour per day to upkeep my frig and freezers and heat up some water for a quick bath.........to those of you using electricity to cook with, CHANGE TO PROPANE you wont be sorry.

By the way, in summer (and sometimes in winter) my two black water tanks outside makes all the hot water that I need for a bath and to do my dishes........yesterday the surface water in the tanks was at 120 degrees, almost boiling.

What altitude are you at dude? ;D

I know the boiling temp goes down the higher you live. But at that temp I think you may have a problem breathing...:o

Note: the boiling point at 43,000' is 121°f or so...


Sorry bud , ;D just having a tad of fun.

This "dude" lives at 1,620 feet......I don't know what the boiling point is but I do have to bring the cold water from the bottom of the tank to the surface to mixed it so that I can use it.....straight from the surface is wayyyyyyy to hot.

FYI , at your altitude , water will boil at about 209°F in a open pot.

And you are right, water does not need to be boiling to burn you.

Might as well beat horn before he posts it.. ;D

Sorry dude!
