The 'best' kit depends on your sun, electric rate, and what your utility allows. Use this framework to filter the noise.

Certifications

UL 1741 inverter, UL 61730 panels, NEC-compliant cabling. No exceptions.

Wattage right-sizing

Match output to your daytime baseload. Producing more than you use just spins your meter — sometimes against you.

Mounting and outdoor rating

IP-rated connectors, UV-rated cables, and brackets sized for local wind.

Warranty

10+ years on panels, 5+ on inverters is a reasonable floor.

Support and US presence

Email-only overseas support is a red flag when something goes wrong in two years.

Educational only — not legal, electrical, or financial advice. Verify rules with your utility, local building department, and a licensed electrician. Last updated: 2025-01-01.
