Using the data in Table 1, explain how there are economies of scale in the global production of commercial solar panels.
Table 1: Global production of commercial solar panels
- 2019: Output of 12 GW, Average Cost of $220 per kWp
- 2024 (estimate): Output of 45 GW, Average Cost of $130 per kWp
- 2029 (estimate): Output of 65 GW, Average Cost of $95 per kWp
