Depends

Homeowners with shaded roofs or mixed panel orientations buy Tigo optimizers through an installer. DIY buyers, unshaded-roof owners chasing the lowest quote, and anyone wary of the active TYGO securities class action look elsewhere.

Gotchas - check before you buy

Guess: Tigo monitoring ties you to Tigo gear; Enphase and SolarEdge ecosystems do not mix.

Support signal is thin: Trustpilot lists 4 reviews total.
