Stacey Said:

Can solar power be made more affordable?

We Answered:

Different materials and mass production is not the problem, it is getting more cells from what is now made to begin with. A change in structure such that cells in block form, that do not need cutting, and are inlaid with conductive traces might be an answer to the problem. Individual blocks that can be wired together to form complete panels would be a definite aid as opposed to how cells are currently produced.

Is Solar Power Affordable?

We Answered:

One installer I know told me not too long ago that solar was still running about $8000 per 1000 watt panel, after the tracking system and labor was included.

If this 1000 watt panel produced power at this full amount for 10 hours a day (probably over-optimistic), and that power was worth 10 cents per killowatt hour, thats a payback of $1 a day, so you would get your money back (not counting interest) in 8000 days.

Most people who do this now are off-grid, doing this for environmental reasons, gambling that electricity is going to cost more in the future, or they're survivalist sorts that like to be self-sufficient.

Many new technologies are in the works that might make this much more competitive.
