About the Company

Sterling and Wilson Solar, the Solar EPC Division of Sterling and Wilson Private Limited, commenced operations in 2011 and was subsequently demerged in 2017. This division was formed to tap into the growing renewable energy market. The company is the leading solar EPC solutions provider in the world, with a presence across many countries. An impressive portfolio of several solar power projects with an aggregate capacity of 10.6 GWp across geographies has positioned Sterling and Wilson Solar as the leading solar EPC solutions provider in the world. Sterling and Wilson Solar strategically focuses on markets that have conducive solar power policies and high solar resources as well as invests in geographies with long-term solar opportunities.

The inception of Sterling and Wilson is deep-rooted in the legendary friendship between Shapoorji Mistry Sr. and Mehervan Daruvala which later evolved into a powerful business partnership. In 1971, Wilson Electric Works merged with Sterling Investments, a group company of the Shapoorji Pallonji Group, to form an EPC powerhouse called Sterling and Wilson. The decision empowered the company to ride on global opportunities and emerge as a leading market player in due course. The new entity Sterling and Wilson Private Limited commenced its operations in the 1970s with a few large-scale projects in the Middle East, further venturing into the Asian subcontinent and various other countries. Within a short span it created a strong presence in regions such as the Middle East, Africa, Europe, the Americas, and Australia. Sterling and Wilson currently has operations in many countries.
