About Us

Derived from the combination of the Hebrew words for Green and Technology – Yarotek was established over seven years ago to bring clean-tech to the Americas. Based in Miami, with a regional team in San Juan, Yarotek’s major emphasis is solar energy generation – particularly in the Caribbean where we are harvesting abundant sunshine to reduce electricity costs. Whether as a developer, system owner or equity investor, Yarotek’s pipeline has a collective capacity exceeding 145 Megawatts, of which over 75 Megawatts are fully built and operational.
