The initial number of 1 square kilometer of PV panels produced per year doesn't pass the sniff test. An average home installation is already 10 square meters, and a lot more than 100,000 installations are added in a year. The global production of solar panels was 180 GW in 2020. Assuming around 200 W per square meter, you get 1 billion square meters of solar panels. So their initial number is off by a factor of 1000.
