According to Stephen Lacey
We are starting to realize grid parity in solar – all with technologies available today.
In solar PV manufacturing, costs have fallen about 18% for every doubling of production.
This modular technology can be produced and installed at a pace far faster than most energy technologies. And businesses are getting amazingly efficient at doing so.
and compared with nuclear
solar brings a different kind of value to the grid. Not only can it be quickly deployed on existing infrastructure (warehouses, commercial buildings, residences) at rates that are orders of magnitude faster than nuclear, it offsets the most expensive peaking power plants – providing immediate economic value.
