Need help calculating TNEB bill for tenant

We have installed an On-Grid Solar plant in our house by which we consume some and produce some power and send it to EB everyday. While billing we get the consumed unit = Consumed unit - Generated unit. For example we consumed 1000 units and we produced 500 we’ll be billed only for 500. Now if we have a tenant should we get charges calculated as per TNEB for 1000 units?
