We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon.
edit: Also, this would capture a very trivial percentage of the Sun's power. A few trillionths per year.
China made 1.8 TW of solar cells in 2025.
The raw materials required to make these are incredibly abundant, we make as much as we need.
