Solar power system exemption extends to essential substation and grid equipment integral to operational generation and evacuation.

A solar power generating system was construed to include not only the generating unit but also connected substation equipment and grid arrangements necessary for transmission, evacuation, and operational functioning. Applying a component-part approach, the HC held that a narrow reading excluding essential auxiliary equipment would defeat the exemption's purpose of promoting solar projects. Because the substation equipment was integral rather than separable or non-essential, it fell within the exempted system under the Madhya Pradesh VAT schedule. The rejection order was therefore unsustainable, the tax determination was set aside, and exemption was directed for the disputed equipment.

Issues: Whether substation equipment and grid used for evacuation and upliftment of power generated in a solar power project are integral parts of a "solar power generating system" and therefore entitled to exemption under Entry No. 71(10) of Schedule I of the Madhya Pradesh Value Added Tax Act, 2002.

Analysis: The expression "system" was understood as a set of interconnected parts functioning together as a whole. On that basis, the Court held that a solar power generating system is not confined to the generating unit alone but includes all connected devices and equipment necessary for its operation, including substation and grid arrangements required for transmission and evacuation of power. The exemption policy was framed to promote solar projects, and a narrow reading that excluded essential components would defeat that object. Applying the component-part approach, the Court found that the substation equipment was not a separable or non-essential item but formed an integral part of the complete solar power generating system.

Conclusion: The substation equipment and grid were held to fall within the exempted solar power generating system, and the rejection order was unsustainable.

Final Conclusion: The writ petition succeeded, the tax determination was set aside, and exemption was directed to be granted for the disputed equipment as part of the solar power project.

Ratio Decidendi: Where a statutory exemption covers a complete system, all equipment that is essential and integral to making that system operational must be treated as part of the exempted system.
