Solar Market for Base of Pyramid Not So Pico

Dexter Gauntlett — April 14, 2014

In an upcoming report on pico solar lighting products (<10W) and solar home systems (<200W) sold primarily to rural communities in Africa and Asia, I cover the unit sales, revenue, and capacity of these small solar photovoltaic systems globally.  One of the most important trends covered in the report is that pico solar has transitioned from a humanitarian aspiration to big business – more than $100 million in 2014.  Corporate involvement in rural electrification has traditionally come in the form of corporate social responsibility initiatives, but real money is now flowing to solar companies serving the base of the pyramid market.  The success of a number of off-grid solar lighting companies and social enterprises has attracted interest from major corporations such as Panasonic, Schneider Electric, and Philips, as well as funding from investors.  Some of the more notable investments include:

  • In early 2014, d.light raised $11 million in Series C funding from DFJ, Omidyar Network, Nexus India Capital, Gray Ghost Ventures, Acumen Fund, and Garage Technology Ventures.  The company is one of the leading pico solar manufacturers, and has now raised $40 million and sold an estimated 6 million pico solar systems reaching 30 million people.
  • In early 2014, Persistent Energy Partners acquired Impact Energies, a pay-as-you-go, off-grid solar service provider working in West Africa that has reached 30,000 customers since 2011.  The renamed company, Persistent Energy Ghana, installs village solar microgrids and solar home systems.
  • In late 2013, Khosla Impact invested $1.8 million in a Series A round with BBOXX, a U.K.-based company that sells portable solar kits ranging from 7W to 185W and plug-and-play solar systems that range between 2 kW and 4 kW.  The company also provides a mobile pay-as-you-go service enabled by remote battery monitoring, which was the primary interest of Khosla.
  • In 2012, Greenlight Planet, one of the leading designers and distributors of solar light-emitting diode home lights, raised $4 million from Bamboo Finance and Dr. P.K. Sinha, co-founder of ZS Associates.  The investment followed previous financing by Dr. Sinha.  Greenlight Planet has sold more than 1.8 million solar lamps since the company was founded in 2008.
  • In 2012, Barefoot Power, one of the largest pico solar manufacturers, raised $5.3 million from three social investment funds (d.o.b. Foundation, ennovent, and Insitor Fund), existing shareholders (The Grace Foundation and Oikocredit Ecumenical Development Cooperative), and a number of private angel investors.

The full report will be released in the next few weeks.  It will discuss industry market drivers and challenges, and includes more than 20 company profiles and country-specific forecasts from 2014 to 2024.
