Possible applications

The solar charger has very low maintenance costs and can provide charging services with low running costs. The solar charger can be used to easily charge mobile phones and radios, which are in high demand in rural areas.

When you use our rechargeable LED lanterns, children can easily study at night, which will help to fill the education gap. For those who rely on kerosene lamps for nighttime lighting, LED lanterns provide not only sufficient lights, but also help to prevent fires that can be caused by flames and the risk of physical harms.

Competitive advantage

1. Ultra-long life

The solar charger we developed applies a unique energy storage system that hardly deteriorates even after repeating charging. The charging performance does not also change through its use for an extended period and we have achieved an unconventional long product life.

2. Excellent life cycle cost

Since it is intended to be used in developing countries, the initial installation cost is low. This is no need to replace the batteries, and the charger costs almost nothing to maintain and provides an excellent life cycle cost. It can provide affordable electricity to people in unelectrified areas in the developing countries.

3. Eco-Friendly Specifications

Conventional solar power generation systems require periodic replacement of storage batteries, such as lead-acid and lithium-ion batteries. These batteries are not suitable for the environment because they contain heavy metals. The products we have developed do not require batteries and are environmentally friendly.

Performance

Technical features

1. Expected life expectancy is over 10 years.
2. Simultaneous charging from 8 USB ports.
3. Input: 12V, 100W (recommendation).
4. Outputs : 5V, 5A / 8USB ports.

Technical Maturity / Past record of introduction

This solar charger is a brand-new product launched in August 2019.

Thus, it has only been tested and introduced in Uganda. However, other products which have similar power systems have been sold for more than 20 years in Japan.

We have received a purchase order from Senegal. We are going to ship our brand-new products to Senegal in September 2020.
