My roof design didn't allow for northern aspect so i have two parallel rows on the eastern side of my house, i'm on the side of a hill and my panels get sun from dawn, and because my roof isn't a tall pitch they stay active till the sun passes my neighbours roofline which is virtually sun down, the west was no good for me either because of a huge patio roof that reflect heat. I reckon the east gives me the best result because they get sun the earliest as well as the afternoon sun and they don't seem to suffer from overheating which can compromise production and lifespan. Of course, it's only be default they are where they are, but no bill since installation means i'm happy with it, my neighbour has his facing north and it's exactly the same system as mine but he doesn't get much of a rebate so comparisons are a little harder, his usage is very different to mine also.
Distribution authorities use rechargeable battery banks for their capacitor banks in their subs, they replace them periodically because they lose efficiency but the technology is advancing, hopefully they will be practical and cost effective for private use soon and just like everything as technology improves they come down in price too.
yeah best I`ll get is 9-10c /kw but hopefully use most during the day, well thats the plan
Just got this Spring bill today $80.
I remember the day we got the solor on, the old meter was spinning backwards, got some good credits, we went over seas for 6 weeks and came home to a great bill
we thought this solor is shit hot, then the new meter was installed, still get the odd credits but nothing like before
That sounds like there is a problem, my 2kw system on a sunny day will produce 13-15kw a day. Not great but half my panels face east so the system only works at capacity from mid morning to early afternoon when all panels are in direct sunlight and that is when sunny not cloudy or raining when I get as low as 4-5kw. Your usage over 3 days sounds high 150kwh ×10=month ×3=3 month billing period =4500 kwh per bill and at what I pay per kwh would be $855, these are rough figures but sounds high. Instead of battery you could go for a solar hot water ( most states offer rebates for install) which would give you heating panels on the roof and a new h/w system. I don't know if the meter switches between solar and grid, meaning during the day you would still be paying for power just offset by what you are feeding in. My last bill showed 1100kwh for 3 months which includes winter, I have all led lighting in my house and an inverter refrigerator with gas h/water (gas for cooking & h/water only) I now longer use gas heater just reverse cycle air con. I don't know how much difference all this makes in the end, I am just a cheap cunt who hates paying bills.
Looking at this very interesting subject, again, I think I did not receive in the 80 cent bracket, but was in 60 cent bracket for sure. Which was great, but now must start all over again.
After homework has been done and discussed with people, who know.
Do Not get "Dodgey Brothers" to install system.
