Living in Cape Town, trust me when I say, you are pretty aware of the weeks of the year when you will have to fall back on utilities.
Living in Canada, Alaska, some USA states, Europe, and you have a whole new world of challenges to sort for months at a time.
You gain this experience from being on solar for more than a year.
Living where you live in South Africa, after a year you may look at it all again and think: I have these panels, they just sit there idling, the geyser being heated. How can I use that wasted energy just sitting there, already paid for?
You have to walk the talk first in your own shoes.
You can thank and pay ME when you are ready.
