EcoZoom’s solar products are mass customized.
Users can obtain it directly from the manufacturer by purchase online.
There is no information about this specific product, however, according to EcoZoom, in 2016 over 40,000 Kenyan families in areas without electricity have benefited from their solar lighting products through a crowdfunding campaign with TRINE. For 2017, they parnered again to reach 30,000 households living off-grid, resulting in a total of 70,000 beneficiaries.
Design specifications include the solar panel, battery and solar lamps. The solar module is a polycrystalline silicon panel with 6 Wp of maximum power point and with an aluminium frame. The battery is Lithium-Ion type with 3,7 V of nominal voltage and 2600 mAh capacity. EcoZoom lamps are LED type and have various light outputs: 150 and 75 lumens. All orange bulbs have red LED lights that indicate when bulbs are charging.
The product is designed for user-customization. For example, additional modules, bulbs, or power banks can be purchased from the manufacturer.Interview with the representative
Replacement components are available.
Most of the modules are independent in the sense that they don’t need to be connected to a central battery source to be operational. The light points have a battery installed within the unit and need to be connected to the solar module for charging purposes only. Once the battery is full the component can be disconnected from the solar panel and be used as the customer wills; either as a torch or can be hung from the ceiling as a bulb. The same is the case for the power banks and the small radio. The battery for the light point can easily be replaced by use of a star screw driver. The batteries are however not available off the shelf but can be acquired from the manufacturer as an after sales service. Interview with the representative
This product has a 2-year warranty and an estimated battery lifecycle of 3 years.
EcoZoom aims to meet the energy needs of Kenyan off-grid families with solar-powered solutions that combine a variety of portable components (solar panels, power bank and orange bulbs) to meet the needs of specific families. From smaller combinations (one light and a panel) to family size combinations with 4 bulbs, two power banks and a radio.
This Solar Home System composed of a 6 Wp maximum power polycrystalline silicon panel and 3,7V and 2200 mAh capacity lithium-ion battery connected to the 3 light points offers 30 hours of lightning after a day of solar charging. This results in a total of 95 lm/W for the brightest lamp of 150 lm and 110 lm/W for the 75 lumens bright setting.
