Well, I live in Ontario and they have a solar panel subsidy program. If your country/region offers a program it would increase ROI by a lot. So, you would have lower costs to buy the hardware. Also, I'm not exactly sure but they buy back solar power at, at least 40 cents per kwH. That's a great price. So it would be best to sell all your solar power to the grid then buy cheap electricity at the lower rate.
