How does it compare to South Australia? SA reaches from 38-26 degrees of latitude, with empty scorching desert in the north (towards the equator) suitable for mass solar generation.
Puerto Rich is just north of 18 degrees of latitude with a predominantly tropical climate, meaning lots of clouds and rain. San Juan, for example, gets just under 3000 hours of sunshine a year, which is similar to places like Memphis or Oklahoma City (vs. Las Vegas, for example, at 3800 hours).
My parents have batteries as well for the solar power. Sorry not super helpful...
Renewable energy ought to be a no-brainer for PR, though. I just wish the utility wasn’t stuck in a spot where it has to triage the basic delivery of electricity and a minimally functioning grid, and instead could focus on investing on rebuilding the overall generation and distribution system.
