Solar panels, touted by many to be a renewable energy panacea that will rid the planet of all those nasty coal-fired power plants, may be a bigger boondoggle than we already thought. We’ve already complained that they do not appear in many instances to provide a return in investment.
It now appears that the time they provide energy before replacement is required is dramatically less than claimed. Thus shortening not only the life of the panels and the electricity generated, but also reducing the return on investment.
If you listen to the mostly-Chinese manufacturers, solar panels work great. They can be expected to degrade about 0.5% a year. So that is how we build the economic models to finance, insure and subsidize the larger solar systems.
In the real world, we are just starting to find out how bogus many of those predictions are. The National Renewable Energy Laboratory says that panels can degrade as much as 4.5% a year. Or more. Put that in your pro forma and see what your banker and insurance agent — or Congressman — say about that.
While we see claims that average solar panels will last 25 to 30 years, the aforementioned claim of 0.5% per year means that solar panels should last an astounding 200 years (100% ÷ 0.5%). At the realistic rate of 4.5% per year they will only last about 22 years before replacement is needed (100% ÷ 4.5%), which is not even the 25 to 30 currently claimed by many and not even remotely close to 200 years.
It gets worse folks. They don’t only degrade, it appears they also can literally fall apart and it doesn’t take very long.
In Italy last year, “they discovered that after one year in the field, over 90% of the (solar panels) from a one megawatt project began to delaminate and ended up on the ground.”
That is a lot of wasted money. 90% down the tubes after being used for only one year. No return on investment and very little ‘free’ electricity generated. All that is left is an eyesore that is a pile of toxic waste, wasted tax dollars and perhaps a tax deduction for a business loss.
We are adverse to the lies about what renewable energy costs and what it’s capabilities are. We’re also adverse to the physical and financial messes left when solar and wind-power are abandoned. We’re extremely adverse to the rush to install solar and wind-power without having full knowledge about the effects. Look at the carnage left in the previous two links to see what we’re talking about.
California seems to be leading the rush off the proverbial cliff via the implementation of AB32, California’s cap & trade law, that mandates power providers to generate 33% of their power from renewable (green) sources by a not too distant 2020.
With many large solar projects planned in California, it would seem to be a logical move to slow down and find out what our money is being spent on and what the return on investment will be as opposed to rushing in head first, only to find another government mandated, costly boondoggle. To know what happens to government mandated boondoggles one only has to look at the Solyndra and Evergreen Solar fiascos.
You can safely bet that when these solar energy plants fall apart at the seams, the taxpayers and energy consumers of California and other states will get stuck paying for the bill. It’s probably also a safe bet that the messes left at abandoned solar and wind farms will be there for decades as a reminder of what happens when the government gets involved in what should be private enterprise.
