Nigeria’s Solar Scheme
The Cheers News reports on the scheme in Nigeria to provide electricity to as many as 10 rural communities. Construction on the project has begun and they are expected to be delivered around January of next year. The scheme will benefit about 5,000 people.

TECHNICAL - INTRODUCTION
General functioning principle
The Solar Defender system is based on a network of optical surface sensors,
directly applied on the single panels and connected, via owner BUS, to a net of concentrator
modules able to communicate, via BUS RS485, with a management/control panel.
Each sensor incorporates a microprocessor for the measurement and detection of same specific
features on the panel’s surface and an advanced communication protocol able to detect and
communicate to the management/control panel, via concentrator modules, any attempt to tear,
remove and tamper both the single panel and the whole system.
The management/control panel signalizes punctually every event type and the exact indication of
the panel and concentrator interested by the event. It can be interfaced with any communication
and alarm system, therefore the way to receive the events is related with the system chosen by
the user.
The operation of Solar Defender is independent from the activation or less of the solar or
photovoltaic system: it can be applied on the first widened panel and in work course, to
guarantee the protection of the system already to open yard. (“Funzione Cantiere Aperto)
