WOWsolar 100 is a solar home system with integrated Pay-as-you-go functionality designed by Amped Innovation in partnership with Driven Innovation and Angaza. This product provides home lighting through an energy system composed of a solar panel, a combined control unit with battery and 3 – 4 LED lamps. A portable radio is also included with the system. Users can upgrade their system by adding solar panels, battery packs, lamps and even a TV to climb the energy ladder. This system is part of Amped Innovation’s WOWsolar Family product which is a verified product of the Lighting Global Quality Standards.
The system is mass produced. Each part of the system is manufactured individually. The main component which contains the software-enabled Pay-As-You-Go interface has a housing that consists of two injection molded parts. At the bottom inside the housing all the internal components are loaded and secured from the back. Additionally, the main housing provides features to allow access to external connectors and to support the internal components. For the status LED's, a custom light pipe is manufactured. Both the housing of the main component and the housing of the external lights lens use high gloss surfaces. This external lights create a diffused light through a domed lens which is attached to its top housing with two screws and four pins.

Distributions to Date Status
Amped Innovation completed initial field trials of their WOWsolar Family product in the summer of 2016 with distribution partners in East and West Africa. As a result the company secured Memorandums of Understanding for 170,000 units in 2017. Amped Innovation has been tasked to deliver over 1.6 million solar power centers during the next five years through partnerships with NGO's and social ventures serving smallholder farmers. As of 2019, Amped Innovation's solar products have reached over 50,000 households.

If pressure is applied on the photovoltaic panel by sitting or stepping on it, the device might break and cause bodily injury or electrical shock. Precaution must be taken regarding electrical contacts or wiring, the person handling them must use adequate safety gear. To avoid electrical shock, the photovoltaic panel must be earth grounded. A minor risk of burns exists due to the heating of the photovoltaic panel's surface by the sun.
Complementary Technical Systems
The system is upgradeable; additional solar panels, battery packs and appliances (including a fan, hair trimmer and extra lamps) may be connected to the system.
