JAMIE: I recommend : Sandro Fattore" <[EMAIL PROTECTED]> I believe in Northern Italy, he makes SUPERB and I mean SUPERB SMALL HYDROS, exactly for your site, contact him, I do not know if he can handle French, English OK. Of course Italian. The attachment is for 1 KW High head..
It would be "cheaper" to have the shortest pipe and transmit the power at the highest voltage possible to reduce the transmission losses. At 220 volts 250 meters you may have about 5 watts lost in the transmission line if well done. Your site is around 300 watts producing 7.2 KW-hour so for you to have the 5 KW you will need a storage battery bank-- so you will be limited to the 7.2 KWHOUR -- power usage management is necessary. The piping depends how the run is, the first 15 meter head is OK for Grey piping, one may go some few more meters if you are careful with the water management control. to avoid Ram Pump effects, then pipe 40 and then pipe 80 Produce High voltage AC for transmission and MPPT converter to charge the battery bank and even leave as AC for limited night lighting ( using Fluorescent lamps [10 or 13 watts ] ). Since you have not bought any land yet, so lets wait until your pocket gets "empty" or almost "empty". How many streams do you have and what water volume and heads ?.
