well, I'm thinking more like grabbing some sun shine in my garage door (?) and beaming it into the car.
it doesn't have to go far to be useful.
I fear the day when people are not allowed to have their own home installed solar panels free and clear.
Fearing an unknown and highly unlikely event is a waste of time. There are clearly more immediate issues. The oil and gas industry along with coal have such a grip on our economy and on the Congress that the day there is no power except what you generate is far, far from realistic.You should fear the day they require you to buy solar panels for your home and prevent you from connecting to grid power.
At current pricing, the payback on solar panels vs electrical grid power is over 40 years, if the panels could deliver full power for 40 years. You should fear the day they require you to buy solar panels for your home and prevent you from connecting to grid power. Solar panels only have a useful life of 20 years (panel output declines about 3-5% per year) Do the math on what year you get "free power" from an investment in solar panels.
Panels also have more than a 20 year life. Manufactures warranties are 25-30 years. No manufacture warranties longer than their projected life nd no solar panels don't lose 5% per year.
40 years? I wonder how you came to this price.
Perhaps the question is which warranty are you talking about. Yes you're correct the panels themselves are ~10 years. They are warrantied to not produce less than 80% in 25 years. So again your idea they'd lose 5%/year is a bit off or every company would be kicking out money after the first 7 years.Only single crystal silicon solar panels are warrented for 20 -25 years
Thin film polycrystalline panels are unlikely to have a warranty lasting more than ten years
This really isn't new. Dirt impacts the efficency of most everything. A panel is fairly easy to clean.Dirt and debris, such as blowing leaves, dust, and shading will also affect power output
Solar panels don't require batteries. Most states enforce power companies paying the home owner back for excess power generation.and how long do you think the batteries will last? and how often will the battery bank have to be replaced in 20 years ??
I believe Dow Chemical makes such an animal.a friend recently installed solar on his home and I will be asking him about his savings. Personally, I would prefer a system where the solar components are "printed" on roof tiles so that there is no added weight on the roof. And maybe printed on the sides of the house as well.
that's the way it works where I live.Solar panels don't require batteries. Most states enforce power companies paying the home owner back for excess power generation.
just saw this interesting tidbit:
Jay Leno has gone 11,000 miles in his Chevrolet Volt on one tank of gas
Meanwhile in China, as the government there isn't controlled by the oil industry, but by themselves, the energy consumption relies less and less on oil, and their economy is getting up and up.We can save billions of dollars from the DoE that is being spent on solar scam industry! Oh wait, this guy probably didn't donate anything to Obama campaign, never mind.
"Economically practical" is very relative I think. If oil reserves weren't depletable, or, well, in politically nasty places, you'd be right indeed.Solar is only economically practical for remote locations (10 mi off grid) used with wind and diesel generators
or where only small amounts of power is needed and trenching is required to bring in power
