PV needs physical resources that aren't for free or unlimited. PV needs space. Most energy used has still an high negative impact on the atmosphere. Low efficiency somewhere is energy potentially wasted that could reduce carbon emissions somewhere else.
Heating is waaay more efficient with heat pumps. Aviation... Well who can still afford it...
There are other forms of storage as well, e.g. hydro, heat storage, and many more
I'm not saying it doesn't have it's uses, but efficiency is important
