Thank you! Do you have any specific "less obvious" keywords that you don't think someone outside the space would be aware of?
That's because my interest and work primarily skew retail (B2C), installer-facing, and mapping, though.
If you're more interested in the field as an investment opportunity for near-future tech, maybe academia would be more the place the look, at upcoming cell chemistries, balance of system costs, manufacturer consolidation and bankruptcies, storage (battery) developments, non-battery storage technologies, etc.?
In my experience, there's been a lot of vaporware in the industry, with new discoveries every year but very little of it ever making it to market. Mostly just year over year improvements in module efficiency, more companies making microinverters or power optimizers, and exciting stuff on the software front for remote site assessments. And of course storage is huge these days.
My read as a grunt in the field is that it's a relatively mature trade that's becoming like plumbing or electrical work, just another infrastructure job that everyone needs. I don't see it as an industry particularly ripe for disruption, but I could easily be wrong lol. If I knew where it was headed, I'd be CEO and not a lowly web dev :)
Sorry I can't be of more help! Happy to chat, but my knowledge is limited to peon level stuff.
