The payouts on solar are monthly and the payouts on blueberries and beehives are twice a year. The projections for solar are between 10% and 12% per year. This is based on an annual increase in the energy price of 8%. If it increases by more than this, as is currently the case, you stand to make more from your asset.I doubt that...but if it is then it's actually worth it.
If that is yearly, you won't even make your money back on the solar panels before they are destroyed after 20 years.
I see they predict 8% p.a. on 1 solar unit and with 10+ units...14% - 32% p.a.
Solar is obviously the way to go thanks to Eskom.
