About SPI
SPI Solar (SPI) is a global turnkey developer and EPC contractor for large-scale solar energy facilities (SEF).  We offer a unique approach to designing, engineering and constructing very high-quality, efficient and sustainable photovoltaic (PV) solar systems for commercial and utility applications.

SPI produces its world-class SEFs from concept through creation, and beyond. Our SPIGuardianTM operations and managment ("O&M") services are derived from our commitment to quality and experience designing and building world-class systems to ensure a lifetime of world-class performance.

SPI Solar develops distributed generation SEFs to provide onsite electricity production for industrial and commercial enterprises. It also develops utility-scale SEFs to provide electricity to power grids serving vast areas. In February 2011, LDK Solar, a vertically integrated solar wafer, cell and solar module manufacturer, purchased 70% of SPI’s stock.  The transaction complemented LDK’s vertical integration, effectively making SPI its downstream development platform. SPI leverages LDK’s supply chain and economies of scale to work as a vertically integrated solar developer and EPC contractor to design, engineer and construct high-quality, low-cost turnkey photovoltaic SEFs for both distributed generation and utility-scale applications around the world.

SPI engineers and builds PV SEFs that are designed to meet the financial goals and energy requirements of customers ranging from large-scale commercial /industrial facilities to multi-megawatt utility-scale installations feeding electricity to power grids serving vast geographical areas.

Vertically Integrated Developer


SPI controls its supply chain from procurement to post-installation operation and management of the systems it designs and builds. Critical to today’s development environment, SPI also provides project financing. This level of control and support enables SPI to design, build and deliver world-class solar system configurations with components that have been validated to work optimally together. SPI’s value-engineered system approach allows SPI to meet system design requirements while delivering highly efficient electric power output with a lifetime of reliable performance. To ensure a lifetime of peak performance, SPI Solar’s SPIGuardianTM O&M services are available for completed power plants through long-term O&M agreements.
