1. Solar‑panel prices are collapsing
"100W 18V for $37 and change." – dhosek
"I bought 30 × 375 W Canadian Solar panels … paid $0.41 / W (~$4,536 total)." – horsawlarway
"We use these newly compiled and delineated solar arrays ... to estimate value‑added attributes …" – abstract (open‑access paper)
2. DIY rooftop/balcony solar is now economically viable
"Power is 13 c /kWh, guaranteed to go up ≥ 5 % / yr. … The loan will be gone in 7 yr, giving 20 yr of free electricity." – testing22321
"I got $7.6 kW installed in BC, Canada … fully installed for $13 k … after a $5 k grant and a 10‑yr interest‑free loan." – testing22321
3. Policy, tariffs and cultural resistance shape adoption
"The people who gleefully mock the issues with renewables do it because they have been trained to want renewables to fail, and to see active support for renewables as a signal for softness and liberalism." – enraged_camel
"American solar installer companies do seem to charge way more than European or British ones." – ragebol
"US policy is actively suppressing renewable efforts; adoption is hampered by regulatory capture and cultural stigma." – parpfish (summary)
