I would first get me a much better, and good looking house with a large area, and then buy the solar system because i got to enjoy the view.
@varmitr Why figure in the energy it took to make every single part of the system? Isn’t that paid for in the price of the materials you buy to build it? Does that make sence to you?
I guess one can always find something to complain about with alternate energy systems.
I find it easier just to say, if you don’t want to have a solar or other alternate energy system, then don’t get one. You won’t save any money, and you won’t have to worry about what the systems save or don’t save.
I’d put some aluminum tape on that exterior pipe insulation, it won’t last too long in the weather.
yeah , but solar system doesn’t have any co2 emission, Last forever, Sun belongs to all of us, you dont pay bill to any big corporation etc etc
this is were constructing your own solar heating system from easily purchased or recycled materials beats out manufactured system hands down everytime!!! I build my own systems here in Houston Texas and I love it, the savings are instant! due to the fact that I try to cut as much conventional power usage out all together.
ah yes very nice system *****5stars*****
well put and good analogy thank you!
Yeah, but it’s cancelled out because a boiler system will have a similar carbon cost from production, but the boiler system will last around 2 times longer so it won’t need to be replaced as much so it kinda halfs that approximately. So it’s not just extra. Although boiler systems will have a smaller carbon cost, this should reduce as this technology takes off and is built in bulk and more economically viable and blah blah blah..
just curious, how much energy is required to build a single solar panel or vac tube?
therefore, how long does that device have to work to provide a feasible returns equal to its construction?
days weeks months years? if it takes 5 years worth of energy to construct it, and twenty serviceable years, it really only has a 15 year cost recovery. Am i making sense or not?
thanks
hi rix, id said screw the grid tie, just get stand alone and get away from the rest of people/utilities.
personal pride in ownership. the grid tie for me is about $40,000 more
Hello
The answer of your question is in the last part of our video. “El mejor video de instalación ENERGIA SOLAR TERMICA”
what happens when it snows or rains, do those solar panels capture sun to work the heating system?
the US has the most natural gas on the planet, enough to last 500 years – natural gas is just methane (97%) and can be found in coal deposits, or gathered from landfills.
This is a wonderful idea: Well presented. Now if they could generate electricity and run the electric meter backward – with a ‘grid-tie’ invertor.
Gas is just indirect solar. And it won’t be cheap for much longer unless you’re willing to go dig up methane clathrates from the sea floor.
dont they have gas
