The short answer on 500w vs 600w solar panel: pick 500W when the job is fast-charging a power station with one portable panel, and pick 600W when the job is a permanent roof or deck array across multiple panels. The 500W example folds with a kickstand for camping; the 600W example bends for curved RV and boat surfaces.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. Safety here means a stated weather code: IP67 on the BLUETTI, nothing stated on the DOKIO. Warranty goes to the DOKIO at 1 year; the BLUETTI states no term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
