399 Done

Finally, it is done.  

399 houses provided with electricity from solar panels, wired for LED lighting, phone charging and a small radio powered by rechargeable battery.  

It is not 400 because one was found to be found to be double-counted. 

30 houses were formed into 6 mini-grids.  In each mini-grid, a larger panel and larger batteries support 5 houses clustered close together for greater efficiency.  

The rest are individual systems, each with a 40 watt panel and its own battery. 

There is an experimental communal television powered by a solar panel and battery.  The signal comes from a terrestrial antenna receiving free TV channels. 

There is an intranet server stocked with videos, educational games and teaching material for English, mathematics, etc.  The server is accessible using a smart phone via a wireless local area network.   It is not connected to the Internet.  

An IOT system monitor the health of the system, and connected to the Internet via a local SIM card.  Hence it is can monitored remotely, from Hong Kong. 

This afternoon we dance with the villagers to celebrate. Everyone was having fun.
