Rabi High School now enjoys constant daytime power for computers, office equipment and the PA system. The larger equipment in the woodwork room requires the generator to be started for short periods. Teachers' residences still have power access from six to ten pm, but most of it is now clean power with the generator only used for limited periods to supplement their needs.
An added benefit is that the inverter now protects the school computers and other equipment from damage. The generator was delivering 'spiky' power that damaged the computers—the school previously had ten donated computers, eight of which burned out.
New education resources
Each year over $7000 will be saved on generator fuel. That is channelled directly into education resources. With the escalating price of fuel, this saving is likely to increase. In this low income community the renewable system is making a huge difference.
With the fuel savings the school is currently establishing a permanent internet connection, purchasing new software, networking equipment, documentary DVDs and building fume cupboards in the science room.
While students are able to study computer science, the school was down to only two functional computers that were donated ten years ago. So nine Apple laptops were donated independent of the core funding of the solar system (computers are not a deliverable of the Foundation).
CO2 saved
Generator use is expected to drop by seventy-five percent, saving approximately 150 tonnes of carbon dioxide over the expected twenty-five year life of the system.
Please note: the carbon saving estimate does not account for the system's manufacture and transport because this is more than offset by the reduced transport requirement for fuel, generator maintenance and probable generator replacement.
For the future
Arranging communication, supplies and installation in remote communities is complex, so a carefully documented pilot was essential. We are delighted to report the project was a great success and is a robust template for future projects.
