It gets worse than that Gramps.
Ok so no power outages, and we have a nice sunny cool day great. Perfect conditions for generating solar energy. Should be pumping out the full 5KW right?
Wrong.
All output from solar systems must also be able to be controlled by the energy company.
If you live in an area where there are other solar panels, it's likely that the
grid will go into 'over voltage' because of the way it was designed and the energy companies will turn your output down to manage the network. In many suburbs it is estimated that solar systems are turned down to as low as 10% of their rated output under optimal conditions when high local demand from air conditioners isn't present.
Oh another one.... Probably the biggest issue with solar.
The list price for electricity is generally around 25c per kw. With some homework and haggling you can get it as low as 17c. I pay 17.5c per kw.
BUT when you haggle for discount, what is the first question they ask you?
"Do you have solar?" If your answer is yes, then they don't discount off the list price. So you pay 25c per kw. ( or whatever your local company charges)
Now in Victoria the 'feed in tariff' is 5c per kw. So even if you generated 1 Kw for every kw you use, you are still up to 3c per kw WORSE OFF than simple haggling and discounting. Most people in southern states use about 4 - 5 times as much as they generate so the savings of not having solar are even greater.
So the answer to the question "How long before my system pays for it's self" is ...NEVER. The longer you have it, the more money you lose.
When you look at your solar rebate, you also need to consider the extra you pay for the incoming electricity. It's like going to the races, gambling $150 and at the end of the day saying you won $50 today. LOL That is how they work...
If you have an old feed in tariff of 60c per kw then the economics are different. Stick to it and never move.
Here is another one of my favorites.
Remember when you got a $4000 rebate from the government? Every company was advertising 3- 4kw of solar for $8000. Then the government dropped the rebate scheme. Guess what? The price of the same solar from all companies went down to $4000 overnight.
