Also i think Solar tech has advanced a lot the last few years and may be winding down soon. What will you do on cloudy or rainy days?

My wife and I are going to be building a new house in the next few years. What I'm planning on doing is running the required wiring and the needed structural support into the roof, but I'll probably hold off actually putting in solar panels until the new tech comes out commercially. This way we can put in the higher efficiency panels later when they come out, without having to pay for renovations later since we did the structural work up front.

They seem a good solution for off grid and remote locations, but otherwise I don't think they are particularly green things to install where you have a mains connection (you'd be better off buying your power from a green energy supplier where this is possible, like in the UK).
The future of solar lies, IMO, in big solar power projects such as we are seeing in Spain, using solar power in the form of focussed heat to drive sterling engines and turbines rather than generate electricity through voltaic cells.

Manipulating solar to reform a glacier? Time will tell.
Geo thermal isn't what some think. My home uses a closed loop, 8feet down, 200 feet long.
No ground water is used in this system. It cools the home using thermal exchange with the ground @ the constant of 50 degrees.
There are open loop systems, made some time ago, but generally being phased out.
Solar is my next step, on grid. Having reduced the energy footprint of the home, I can now work to eliminate it.
All day the solar will feed the grid and my home. End result if all calculations are done right will = 0

This is my worry...buying in too early.
