If you own the property you live at, getting solar makes sense. Electricity is just going to keep on going up, not going down, at least from Eskom.
You don't even have to go the whole hog. You can install it in stages if you can't arrange the capital in one go.
At the end of the day, each person needs to do the math and figure it out for their households. Even in Cape Town during winter we've probably cut our electricity costs by at least 75% over the last few weeks since we got solar installed.
We basically have our install set up to only use the grid as a last resort. On sunny days we haven't even used a single unit of electricity from Eskom. On cloudy days we draw maybe 50% what we used to. And this isn't on some mega build. It was 130k in total. Less than a budget car.
In the short run it stings, but in the long run it's going to save thousands.
