About Tigo

Tigo is an American based solar panel optimiser company that was founded in 2007. Combining a unique systems-level approach with expertise in semiconductors, power electronics, and solar energy, they developed the first-generation Module Optimizer technology for the solar industry in 2007.


Today, Tigo offers a full platform of integrated and retrofitted (mounted on an existing installed PV system) communications technology. By partnering with Tier 1 panel and inverter manufacturers in the industry, they are able to focus on its key innovation through the TS4 Platform.


Selective Deployment of Optimization: When using a single string per MPPT, optimization can be selectively deployed on the shaded modules.  By using optimization only where needed, the user can optimize system performance at a lower cost.

Tigo Case Studies

36% Energy Boost with the Retrofitted Optimization

A Greek residential PV system significantly improves energy harvest over 6 months with TS4-R-O.

First Full Mega Solar PV system in Japan


Without the Tigo optimizers on the array, the plant would be producing 5-10% less than a traditional array.
