This book provides a comprehensive overview of the technology behind the pico-solar revolution and offers guidance on how to test and choose quality products. The book also discusses how pioneering companies and initiatives are overcoming challenges to reach scale in the marketplace, from innovative distribution strategies to reach customers in rural India and Tanzania, to product development in Cambodia, product assembly in Mozambique and the introduction of ‘pay as you go’ technology in Kenya.
Pico-solar is a new category of solar electric system which has the potential to transform the lives of over 1.6 billion people who live without access to electricity. Pico-solar systems are smaller and more affordable than traditional solar systems and have the power to provide useful amounts of electricity to charge the increasing number of low power consuming appliances from mobile phones, e-readers and parking metres, to LED lights which have the power to light up millions of homes in the same way the mobile phone has connected and empowered communities across the planet.
The book explains the important role pico-solar has in reducing reliance on fossil fuels while at the same time tackling world poverty and includes useful recommendations for entrepreneurs, charities and governments who want to participate in developing this exciting and rapidly expanding market.
'John Keane is one of the world's pre-eminent authorities on pico-solar, both the technologies involved, and the marketing of them. This book is a wonderful encapsulation of his expertise. I have been priviledged to be a colleague of his in the most successful enterprise yet in selling pico-solar in Africa, SolarAid's retail brand SunnyMoney. I know first hand how much social good John Keane's vocational life, and now his book based on it, are doing and will do for the world.' - Jeremy Leggett, Founder and Chairman of SolarCentury and SolarAid
'It’s a very good book which covers an important topic. Pico-solar products have the potential to help rural communities which do not have access to electricity in many ways, such as helping farmers charge their phones to stay connected and students to study at night.' - Alex Nana Yaw Brako, Logistics Operations Manager, West & Central Africa, Barefoot Power Africa Limited
'An inspiring, accessible and useful book which gives a good overview of how small solar solutions are helping light up parts of Africa.' - Fredrick Ouko, Executive Director, Action Network for the Disabled, Kenya
'Young people are leaving rural farming communities for urban lifestyles, resulting in an ageing countryside, globally, with a dearth of people to take up agriculture and feed the growing population. Pico-solar provides one innovative means by which rural lifestyles can be improved, enticing more people to stay in and contribute to the development of rural areas. This book provides an excellent overview of the sector and an improved understanding on how pico-solar products can improve rural, agricultural communities'. - Courtney Paisley, Director of Young Professionals for Agricultural Development (YPARD)
'I found the book really useful and interesting. It provides a great introduction and overview to the new and exciting pico-solar sector, covering a wide range of issues, including the technology, the challenges facing last mile distributors and the positive social impact pico-solar lighting in particular can have. It's clear that pico-solar energy solutions promise to help rural Africa gain access to clean, renewable energy and have a big social impact on rural communities. Furthermore, with the relatively non-existent empirical literature and documented successful distribution models of pico-solar products in Africa, this book is timely and provides suitable case studies and guides for those interested in the pico-solar industry in Africa.' - Emmanuel Aziebor, Associate Advisor, Renewable Energy, SNV Netherlands Development Organisation, Ghana
'Congratulations on the book. I think it will allow for a lot of information flow on the technical aspects of solar and the solar market in general. Many people working in the pico-solar sector will identify with the wins and challenges discussed in the book. The book is also good for non-technical people and as an introduction for people new to the field.' - Anne Kayiwa, Country Manager, Barefoot Power, Uganda
