Onsite solar and storage is the big issue. That's why most solar plants come with a peaker gas plant. It's cheaper to provide additional demand via fossil fuel

It's cheaper to provide additional demand via fossil fuels than to rely on storage solutions. You need a huge amount of storage.
- Retric 4y agoMany solar power plants come with 3-4h of battery simply to time shift output to peak demand. Because solar is DC you effectively skip inefficiency from DC>AC (Solar to grid) and DC>AC (Grid to battery) conversion. On top of this you can use the same DC>AC equipment for both the batteries and solar plus being able to convert DC>AC to charge batteries from the grid becomes optional.
