There is access to the second floor of the house. I'll be putting a (bought it from HF last year) hoist in any time, to get the sheet goods up, then the tools.

You're forcing a comparison of apples and oranges if you use that approach. Figures for output are peak numbers, but anyone running the financials knows that you have then to apply data relating to insolation, which are location dependent. The figure of $/peak watt is much more useful in practice. Sylvia.

I fell three times this week, just walking through the house. Luckily, I was next to a wall all three times and fell against it.. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

A payback period (which doesn't exist at anything like current unsubsidised pricing) will also depend on location. Sylvia. |
