On the final day in this remote city (last 2 hours), they were still trying to set up a new Solar Panel for testing. They said they could not afford to pay somebody to install it. They have 2 new Solar Panels, which they got 2 days before we arrived. They also have an MPPT controller, which was given to them some time back. I told them I had never installed a Solar System, but we could try. Without proper tools, we finally assembled the system after 1.5 hours.
After 2 days, they reported that the Solar system was working. 😊
