"...environmental effects ... associated with the manufacturing of solar PV panels and the required batteries to make that technology compatible with a modern society..."
Yeah, let's talk about those.

TLDR: "Most estimates of life-cycle emissions for photovoltaic systems are between 0.07 and 0.18 pounds of carbon dioxide equivalent per kWh"
and:

TLDR: "Enhanced geothermal systems, which require energy to drill and pump water into hot rock reservoirs, have life-cycle global warming emission of approximately 0.2 pounds of carbon dioxide equivalent per kWh."
So, PV is slightly better. Yes, there are some hazardous chemicals used in PV cell manufacture. Can you claim that none are used in fabricating a geothermal plant ?
