Integrated solar device qualifies as a solar power generating system where the core module converts energy and other parts regulate use.

The Dusk Dawn System was treated as a solar power generating system eligible for exemption under the notifications for non-conventional energy devices and systems. The Tribunal found that the solar photovoltaic module converted solar energy into electrical energy, while the controller and housing only applied or regulated the generated power for automatic street-light control. As the module was not an isolated part but formed an integrated system functioning on solar energy, the product fell within the notified category. The denial of exemption was therefore unsustainable, and the assessee was entitled to the benefit of the notifications.

Issues: Whether the Dusk Dawn System was classifiable as a solar power generating system covered by the exemption notifications for non-conventional energy devices and systems.

Analysis: The exemption covered non-conventional energy devices/systems specified in the relevant list, including solar power generating systems. The system comprised a solar photovoltaic module that converted solar energy into electrical energy and an electronic controller and housing used for application of the generated power. The Tribunal held that the solar photovoltaic module was not an isolated part in the facts of the case, but formed part of the integrated system designed to work on solar energy for automatic street-light control. On that basis, the whole system was treated as a solar power generating system for exemption purposes.

Conclusion: The denial of exemption was unsustainable, and the assessee was entitled to the benefit of the notifications.

Final Conclusion: The exemption claim succeeded because the product was held to fall within the notified category of solar power generating systems.

Ratio Decidendi: Where the essential functional component of an integrated device converts solar energy into electrical energy and the remaining components merely apply or regulate that power, the device may be regarded as a solar power generating system for exemption under the relevant notification.
