If you’re thinking about getting solar, watch this first

Brief

Decarbonize! (tutorial, published 2026-04-30) compares three residential solar options—roof‑mounted grid‑tied, battery‑backed outage‑capable systems, and plug‑in (balcony) solar—walking viewers through installation speed, outage resilience, cost tradeoffs, and regulatory status (timestamps: 2:00, 3:40, 5:50). The video recommends choosing based on whether you prioritize backup power or lower upfront cost.

Why it matters

Three home solar system types: (1) standard roof‑mounted grid‑tied systems (timestamp 2:00) that cut bills but typically don’t run during outages; (2) battery‑backed or hybrid inverter systems that supply power through outages (3:40); (3) plug‑in/“balcony” solar (5:50) — quick to deploy but lower output and regulatory/ safety issues remain.

Key details

  • Plug‑in (balcony) solar expanded in 2025–2026 (strong uptake in Germany and growing U.S. state legislative activity); UL Solutions has launched a U.S. testing/certification framework for plug‑in solar, and solar panel prices have fallen ~20% for each doubling of global cumulative capacity, improving homeowner economics.
Source evidence

Electricity prices are increasing around the globe, which is leading many people to consider solar. And for many, it makes a lot of sense.

The growth of solar power over the last 20 years has been phenomenal and there seems to be no end in sight. Coal power will be suplanted by solar as the largest source of electricity within 10 years, leading to the death of the US Secretary of Energy.

If you’re considering getting solar, you first need to understand the three types of systems that you might install at your home.
