This applies to Australia, but no doubt is happening in other countries too.
Solar systems are marketed as a way to have free electricity. But free to whom? The customer, or the power companies?
Many people have been duped into spending thousands on solar systems for their homes. The power companies agreed to pay 47c per kW/h, which made it
look like an attractive investment. Now they are reducing the amount they will pay for the power you reduce to 16c per kW/h.
In order to get "paid" for the power you supply to the grid, you need to have an import/export meter installed, which looks like this:
This replaces the old electricity meter like this:
This is what enables the power companies to get their "free electricity" (or almost free). See, the import export meter seperately
how much power you use from the grid, and how much you supply to the grid. This gives them the opportunity to charge a different amount for what you
use and what you supply. So, in typical corporate fashion, they are going to start charging more and more for what you use, and less and less for what
you supply. Eventually, they will pay you nothing for what you supply them, while selling it to your next door neighbour for big dollars.
The way to avoid this scam is to not
install the import/export meter. Keep the old one instead. You won't get "paid" for electricity you
supply to the grid, but instead you will save
whatever rate the power companies are charging you. See, the spinning disc you see in them will
actually start spinning the opposite way when you start supplying power to the grid. It's like winding back the odometer on a car, except perfectly
legal. This denies the power companies the opportunity to set different prices for what you and they supply, meaning if they raise their prices, the
amount you save increases too.
So if you are thinking of going solar, remember that your bills will be higher
if you allow them to "pay" you for what you supply.
