And yet sometimes I wonder. In the Uk you need most of your energy in the cold dark winter. So if you require enough non solar renewables to get you through the winter with net zero and those renewables are still available in the summer time are large scale solar not a bit redundant? Sunnier countries that have high electricity demand for air conditioning during the sunny periods would seem to have a better match mind.

To be honest, peaker plants that sit offline for most of the year but can spin up in unfavorable conditions seems like an ideal application for fossil fuels. They're basically grid-scale emergency generators. Building an oversized battery farm that can store 3 weeks of energy and gets used once every other year probably won't make economic sense anytime soon.
