yes we always knew we wouldn’t get the maximum with the east west split, in fact we deliberately put half each way to maximise the length of time we were generating. We also went for top end panels to ensure we generated as much as possible and degradation was slower.The quoted figure assumes a north facing panel at the correct tilt angle. As you are E and W the max performance will be less which is much less important that being able to use the generated electricity.
Just received a quote for 15kw roof mounted all facing one way - so 1 three phase inverter
circa $19000 (net). But all facing NE
ill probably go 10kW as I wont be able to use all of the generation and ill just get net feed in tariff for the rest.
For 6 months of the year we will use every scrap of what we generate - as soon as we turn the floors on. We still have another roof (also east-west), where we can put more panels, but we thought we would see how this went first and what our savings were. Also given our age and intention to sell the house in another 8 to 10 years whether it would be worthwhile doing it,
We are paying around 15.5c and our feed in tariff is 12c, so we are expecting our bill next week to be very small .
