O.T Carbon Tax v's PV ecomonic? but for who 19-Aug-2011 At 6:02:22 PM lacto

My pv feeds back into a SWER line with 12 houses , 3 active dairies and 3 parttime dairies. I very much doubt that any of my feed back would ever get back to the start of the line and even if it did would never get back to the area main substation . Produced here consumed here . Otherwise the power comes from Latrobe valley to morang , then dederang ,shepparton or snowy dartmouth or kiewa a distance of hundreds of kms with associated losses.On high use power days the coal "base load " is fully used say 6500mw everything over this is provided by consumable generation so Pv stops the use of gas , or water which can then be used later.so it is saving considerably for the grid.
thereare some very large pv systems around, bendigo has a 300kw array near the saleyards and many industrial buildings have large arrays (greater than 5kw which is the cut off for feed back)
If you actually are consuming power during sunlight hrs then pv is economic without any subsidies and the differential between peak and offpeak is starting to encourage people to use batteries charged off peak and used during peak . I saw someone with a nine hundred kg 48v forklift battery which he got for nothing as it had reached its 2 year "life" which he is connecting up on his house .
