Are you suggesting that solar panel factories are really in the dummy manufacturing business? Hmm, I think you're onto something here.

With google you'll find many sites to help you building your own energy-plants Solarpanels in 2004 costs were € 7,55 W/P In 2008 it was € 5,00 W/P in 2009 it was € 4,50 W/P Now they cost € 2,05 W/P In 2015 it will be about € 1,00 W/P or less, so solarpower has a future! -- Ik praat liever tegen een domoor, dan tegen dovemansoren.

The grid in my country is getting more expensive by time. Every year I have used the same amound of energy, but the prices is about € 100,00 more. With an of-grid installation, it's only a matter of time to be cheaper as the energycompany. It doesn't matter how you generate your energy, it's just cheaper to use the energy around us like sun, wind or water. You just need the space to build your plant and the money to invest. If you're living in a big building with many other families, you probably have no chance to generate your own energy, except methangas. -- Ik praat liever tegen een domoor, dan tegen dovemansoren.

Really disconnnecting yourself from the grid implies having some other method of providing power when your solar panels won't. Energy storage is a problem. Batteries are expensive, and have a short life. And even if you've installed batteries to handle the nightly loss of solar power, you still need something else to cope with cloudy days. Your ultimate backstop is presumably a fossil fueled generator, even if you hope not to use it much. All of this costs money. Getting a really independent system down anywhere near the cost of grid power is a tall order. I suppose some people might be happy to use power when it's available, and do without when it's not, but few would willing to live that way. > > It doesn't matter how you generate your energy, it's just cheaper to use > the energy around us like sun, wind or water. > You just need the space to build your plant and the money to invest. Money invested has a cost. At its simplest the cost is the interest forgone - instead of buying the gear to produce your energy, you could have put the money in the bank, earned interest on it, and used the interest to buy energ from the grid instead. Even if you do decide to buy the plant, it won't last forever (batteries particularly), so you need to allow for future replacement. It's not a one-off investment. Sylvia.

Solar power has always had a future. The question is whether it will ever have a present. ...quite like fusion. |
