About Little Sun

Little Sun is at once an inclusive social business, a global project, and a way of connecting the world through sharing light and energy. Founded in 2012 by artist Olafur Eliasson and engineer Frederik Ottesen, Little Sun is invested in delivering clean solar products as well as raising awareness about the importance of sustainable energy for all through special projects and events around the world. The Berlin-based company’s eponymous first product, the Little Sun Original solar LED lamp, was developed to get clean, reliable, affordable light to the 1.2 billion people worldwide without access to electricity living in ‘off-grid’ areas, with a particular focus on Sub-Saharan Africa. In 2016 the second product, Little Sun Charge – a solar phone charger and lamp, was launched. It is being followed in 2017 by the Little Sun Diamond, a sparkling and beautiful smaller solar lamp.

The Little Sun product’s unique designs have made the units popular across the globe – in addition to a growing number of African countries, Little Sun is sold in Europe, Canada, Australia, Japan, and the USA. Little Sun’s innovative business model utilizes revenue from sales of Little Suns in on-grid areas to subsidize the delivery of Little Sun products to areas beyond the grid at reduced, locally affordable prices.

Little Sun addresses the need for light in sustainable way that benefits off-grid communities, creates local jobs, and generates local profits. Rather than a short-term fix of donating lamps to an off-grid area, Little Sun works with and trains local entrepreneurs to build profitable local businesses that distribute Little Sun light.

In April 2014 Little Sun received a ground-breaking $5 million impact investment from Bloomberg Philanthropies, making it possible for the company to dramatically scale its operations across the African continent.

As a social business, we are inspired by B Corp’s high standard of recognising companies who are not only affecting positive change worldwide, but also revolutionising the type of impact businesses can make while transforming their innovative ideas into action.

The Change We Seek®

Little Sun is a social business and global project with two key objectives:

1. Bringing sustainable solar energy to the 1.2 billion people in the world without electricity.

2. Raising awareness of the importance of sustainable energy for all, by activating and inspiring people all over the world to join Little Sun’s campaign for worldwide sustainable energy access.

Little Sun’s vision for the future is a world where the vital resource of clean, affordable energy is available to everyone. In the words of Little Sun founder, artist Olafur Eliasson, ‘Access to energy and light allows you to determine the direction of your life.’

Use of Little Sun products in off-grid areas eliminates the indoor air pollution, breathing-related problems, burns, and house fires caused by kerosene lanterns and candles, while supplying light and energy. With Little Sun, people can work, study, socialize, and extend their daily activities into the night – safely.

This increased access to solar light and energy is making off-grid poverty reduction strategies more effective, as businesses can extend their hours, thereby increasing their revenue. Students are now studying without the smoke of kerosene lanterns hurting their eyes. Cooking and socializing have become more enjoyable. The structure of off-grid communities is being strengthened from within by local entrepreneurs as they deliver sustainable Little Sun solar products.

Solar energy is bringing wide-reaching opportunities for safer, healthier, more productive, and more sustainable living to the world. Little Sun is helping bring about this positive shift, as ultimately, the company is set to become a large-scale solar energy provider, with the Little Sun Original, Little Sun Charge and Little Sun Diamond being the first three products in a long line of solar products, functioning as the important first and second step – of many – up the sustainable energy ladder.
