Please read this before using these numbers
These figures are indicative estimates generated from the assumptions shown above, not a guarantee of savings. Actual generation and savings depend on your roof orientation and shadow, local weather, DISCOM tariff revisions, net-metering policy and your own consumption pattern. A written proposal is issued only after a physical site survey.
