On PV price drops, they are pretty much on trend, using Wright's Law. There's about a 16% reduction in cost per doubling of cumulative production.[1] If announced capacity expansions and renewables commitments come true, we can expect four cumulative doublings of installed PV modules in the next decade, which drops their price by half. However perovskites could gazump that. If their calendar lifetime can be made acceptable (currently around 10 years), they offer capital PV module costs about a tenth of today's. Also a version of Amdahl's law applies. Modules are now under 20% of total system cost: cost like the inverters, the connection to the grid, earthworks, structures and wires, installation labor, and so on, add up. Putting batteries on the PV farm means most of these costs are only incurred once, for much more electricity produced. 1. https://www.cell.com/joule/fulltext/S2542-4351(22)00410-X https://www.cell.com/joule/fulltext/S2542-4351(22)00410-X
