Many of the large transport companies that operate fleets of trucks do not actually own the tyres that their vehicles run on! They lease them from tyre management companies [eg, Tread Setters]. It works cheaper than holding a huge stock of tyres in their warehouses.
Now; one time a long serving and loyal driver was retiring and the employer wanted to give him a fitting send-off. So they decided to give him the 40-tonne truck that he had driven for the last ten years.
The hand-over ceremony was done and the retiring driver was asked to collect his lorry the following week. When he went, he found the truck all cleaned up and re-painted but it had no tyres - just rims!
Upon asking about them he was told "Si unajua tyres sio zetu. Wewe fanya hivi, enda nunua zako ulete tuku wekee halafu uchukue gari yako."
That was a big problem: one truck tyre costs about sh50k and he needed 22 of them: that's a cool sh1.1m - which he didn't have of course!
So what has this got to do with solar power?
Sunshine is free and we have plenty of it. Unfortunately, the process of converting it into electricity is very expensive. It will cost you about a million bob to replace your KPLC connection and enjoy the same appliances that you have in your house.
It's like the free truck without tyres!!
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
