This study is an attempt to identify probable markets for distributed solar lighting systems in International Solar Alliance countries The study looks at parameters such as level of energy access, household income, household expenditure on energy and leverages business data and decisions like relative product pricing, threshold market potential, and the likes to arrive at a list of nations which could be focussed on. The study found nations of Ghana, Kenya, Uganda, Philippines, Mozambique, and a few more as the biggest possible markets for standalone solar lighting systems. Much of this could be attributed to the existence of a fast evolving financial eco system, PayG model, which allows consumers to purchase lighting essentials on an instalment basis. While Asian markets like India, Bangladesh and Cambodia also have huge potential, the lack of financial model along with heavy subsidy on the fuels like Kerosene deter Organisations to invest in setting up retail shops. With increasing focus on climate change as well as energy access for empowerment, governments, private bodies, CSO’s and many other stakeholders are heavily invested in solar energy systems. The study is an attempt to add to the existing knowledge bank.
