HI Chris,
Thanks for feed back.
As to use, I want to net meter down my bill, avoid batteries for time being.
My calcs show about 1/3 to 1/4 of average use could be met. ROI at current
rates is only $40-50
month... but if I can put in a system for $2-$3K or less, it seems worth it.
I.e 1/2 the cost of
exquivalent solar and way less obtrusive.
PLue I expect rates to rise steadily.
My state and power co have net metereing rules for solar, and I expect I'll
have to jump thru aome
hoops to make my case from hydro, but would prevail.
As to your suggestions, yes, I am concerned about clogging, etc. as that has
already happened
for a scary time... twice! I posted pics of the site and one shows the
'maelstrom' I got after a
clog raised water about 18" before I freed it. Dock was floating free till I
tied it
beteen wier and dam.
THe siphon idea could work but how do I regulate flow? I preseum pond level is
set by where I
place intake of siphon?
Also, as i said, my land boundary is 'right on' the base of the dam... no room
to work or set up
unless I work inside the outflow pipe( I think it's 24 or 30".
I may follow up with you on dealing with state and power co at a later time.
thanks
