Very Interesting reading about the northern hemisphere. We down-under in the land of Aus have similar issues of which direction to face the panels. First of all we face to the north instead of south otherwise east and west are the same.
1) I have a 2 KW Gross system that feeds the grid directly and my generous government decided to pay me $0.60 per KWh so I am building a credit. We are also on time of day charging so 2 pm to 8pm is peak @ $0.49 per KWh. In this case I have a north facing and a west facing aspect to my dwelling. I split the 20 panels equally with 10 panels north and 10 panels west. I was told I gained 5% additional with this. This system cost $5890 and so far after almost 3 years has earned $4000.
2) I have just signed up for a 2.5 KW Net unit to be installed in 5 weeks. I had the option of 50% east and 50% west or all on the west side. This was to maximize the early morning sunlight and the late afternoon. The company I chose advised it would increase the installation cost to split the system as suggested. As a result of reading these threads I am glad I opted for the West side as I will maximize the generation during the 2pm to 8pm high cost period particularly during daylight saving. I will only be paid $0.077 per KWh for the excess energy sent to the grid however I have decided to add this system (Pay back est 5.4 years) to reduce the daytime electricity which averages $0.32 Per KWh and hence this saving when my subsidy stops in 2 years will still mean I do not have to pay any electricity bills. In other words I should be earning $0.32 per KWh.
3) The third system my son has purchased is a 2 KW system that will pay off in the future. He is flat rate charged and has off peak hot water. He lives alone during the week and is at work from 5-30 am to 4-30 pm and hence has little use during the week. We expect him to generate to the grid @ $ 0.077 during the week and use most of the solar during weekends. His main uses will be lights, air cooling and heating and the water pump to pressurize the water lines.This will only be installed on the west facing roof.
Hope this is of interest.
