To learn programming in Java, I've written a little utility that provides
_basic_ information on developing/designing a small home/cabin PV system
-- listing and totaling loads, PV panels, batteries, and inverters, as
well as estimated reserve time. Data can be printed or exported to a .csv
file that can be imported into a spreadsheet.
Source code is included, as well as a simple manual.
The program is called PV_calc, and is available at:

I might fiddle with it some. I'm thinking a duty cycle variable (or is
it in there?) Like some of my items are only on for x hours a day, and
i'm generating power at night when everything is completely off, so thats
a factor.
Haven't done much java but if I get motivated I might screw around in
your source.
thanks again man!

I commented the source pretty well (I think), so editing it shouldn't be
_too_ much of a hassle...
In the documentation, it mentions that the loads are assumed to be
operating only a certain number of hours a day -- the "undefined" loads
default to 6 hours/day, for example. You can compensate for your hydro by
quadrupling the power it generates.
Alternatively, if you export to a .csv, it dumps the hours/day info on
the loads, and you can also insert your hydro in the power gen section.
