Even after the price per kilowatt hour for solar reaches grid parity it isn't worth installing, because you need to pay for the capital cost of the backup power supply to meet the same demand, but producing power over less of the year. Solar with storage to have grid parity you need to reduce generation costs by a fair bit again.
