I'm all for solar & I'm planning on investing $10k in a small setup myself - but solar has some significant issues. solar panels generally dont get 100% of the advertised rate, are really only about 24% efficient with bleeding-edge tech, and degrade over time which requires constant upkeep in very large installations. they're also somewhat susceptible to environmental hazards like hail or sandstorms. additionally, you have to store the power somewhere so it can be used during the times it isnt sunny (generally more than 50% of any given day). battery tech has come a long, long way in recent years but we need long-term energy storage solutions that can be built at scale.
