It is true that the electricity supply in Zimbabwe can be described as erratic. During my stay, power would be off during the day most days (although that was improving before I left). This meant it was going go be a challenge for both Pakati schools once the computers were in place.
During my discussions with the Head of the Secondary school, Mr Chifaka, he told me that at both Primary and Secondary schools they had a solution: both have Solar power. He showed me the set up at Pakati Secondary during my recent visit.
The resulting supply proved more than enough to power the 4 PCs and a laptop, with a similar set-up at the Primary doing likewise there.
