Reply:- As per Section 16. Eligibility and conditions for taking input tax credit.

(1) Every registered person shall, subject to such conditions and restrictions as may be prescribed and in the manner specified in section 49, be entitled to take credit of input tax charged on any supply of goods or services or both to him which are used or intended to be used in the course or furtherance of his business and the said amount shall be credited to the electronic credit ledger of such person.

(2) Notwithstanding anything contained in this section, no registered person shall be entitled to the credit of any input tax in respect of any supply of goods or services or both to him unless,––

(a) he is in possession of a tax invoice or debit note issued by a supplier registered under this Act, or such other tax paying documents as may be prescribed;

(b) he has received the goods or services or both.

Further, as per Section 17(5) (d), the ITC is not admissible on such goods or services or both received by a taxable person for construction of an immovable property (other than plant or machinery) on his own account including when such goods or services or both are used in the course or furtherance of business.

Since it is not an immovable property, in our opinion ITC on solar water heater installed for hot waters to rooms, will be admissible.Solar power heater is an equipment.
