ovSolar Home Power
ovSolar (Omnivoltaic Power Company Limited)
A solar home system with a solar panel and a battery that can light up to 5 lanterns, mobile phones, smartphones, radios and a TV.
Launched in 2017, ovSolar Home Power system provides home lighting through an energy system composed of a solar panel, a lithium-ion battery and lumen lamps. Designed by ovSolar, this system powers multiple lamps (up to 5) with three-level brightness (200/100/10 lumens) for over 76 hours of lightning. It has 2 integrated USB ports that enable universal charging of mobile phones, smartphones, radios and a TV system. Pay-As-You-Go functionality is also available.
ovSolar operation and production center is located in Shenzhen and Guangzhou in Hong Kong, China.
Africa and South Asia. Over 30 countries and regions.
Goal 7: Affordable and clean energy
Mass customization in the ovSolar operation and production centers in Shenzhen and Guangzhou in Hong Kong, China.
Users can purchase the product from the manufacturer.
There is no information about this specific product, however, according to ovSolar over 2 million people in areas without electricity have benefited from their products that include various model (ovPilot, ovBeacon and TD100) solar lanterns.

Design specifications include the solar panel, battery and solar lamps. The solar module is a polycrystalline silicon panel with 8 Wp of maximum power point. The battery is lithium-ion type with 3,7 V of nominal voltage and 8000 mAh capacity. Fosera lamps are LED type and have various light outputs: 200 lumens/100 lumens/10 lumens.
Technical support is provided by the manufacturer.
The product has a 2-year warranty covering manufacturing defects, however, according to Lightning Global the battery is not easily replaceable with common tools.
The product warranty is two-years, including the TV. The expected lifecycle is unknown.
ovSolar works to promote solar energy lighting in regions lacking electricity in a safe, environmentally friendly and sustainable manner. The company has actively taken part in the Lighting Global Quality Assurance Programme launched by the World Bank and IFC, designing products that aim to keep the balance between quality, performance, features, usability, and affordability.
A Solar Home System composed of a 49 Wp maximum power polycrystalline silicon panel and 10,8 V and 20 Ah capacity lithium-ion battery connected to 5 light points, the Fosera TV, a basic mobile phone and a smartphone has the following running hours after a typical day of solar charging (5 kWh/m2/day):
When used separately: The 4 lights of 2000 lumens in total are powered for 12h, the 500 mA torch for 450h, the 24” Fosera TV for 12h, the basic mobile phone (3,7 Wh) for 34 h and the smartphone (5,7 Wh) for 22h.
When used in combination: The 4 lights of 2000 lumens in total are powered for 7,5h, the 500 mA torch for 7,7 h, the 24” Fosera TV for 3,7h and the basic mobile phone (3,7 Wh) for 2 h. The smartphone is not specified.

The Solar Home power is a “plug and play” device, however, electrical installation and control guidelines provided by ovSolar must be followed to avoid electrical shocks.
ovSolar commercializes a 24-inch TV screen that can be connected to the Solar Home Power system.
There is no academic research on this specific product, however, the this paper gives a review on solar home systems for rural electrification:
