Here in Arusha you can buy small household solar systems. However, we find that they are not durable. Instead, we install solar systems of our own design with carefully chosen parts.
For electric service, the people prefer the micro-grids we put into their family settlement. These are at their shared expense and include a panel, battery, controller,and underground wires. The wires go to all the houses, buildings, and corrals.
Perhaps a year or two after installation the people get in touch to report problems. Maybe the lights don’t work after 9 pm. Perhaps there is one house with no light, but the rest are okay.
It is important to have a well-trained team of electricians who can identify the problems and fix them. But it's not easy to learn how to diagnose a problem if the technology is unfamiliar.
The International Collaborative has held training workshops where the learners build electrical systems. We secretly introduce problems and ask the learners to find them.
But we find that with technical diagnosis training, it works best to take the team along to observe us in action. We bring a good meter, tools, and spare parts, We search and find the problem while thinking out loud.
Sometimes there are bad connections in a switch. Other times a battery is finally getting old. And sometimes we need to try the simplest things right from the start. We might take a light bulb that is working in one house and try it in the house with no light, and find the house just needs new bulbs. Our team is learning.
