Clearly a sarcastic question, but as solar panels become vastly cheaper, the battery storage requirements to effectively guarantee power on demand become much less onerous. The kWh of backup required for a solar PV system sized to maximum demand is much more than (e.g.) a PV system sized to 2x maximum demand.
