Better Education

Better lighting impacts significantly the time children spend for studying, reading and homework. "In Bangladesh, a study revealed that when solar-powered lighting was introduced, children from the newly solar powered homes remained awake longer each day and used 38% of their additional time for studying and reading. Similarly, a study of portable solar lighting impact in India found that the introduction of solar lighting raised average study hours of students per household from 1.5 hours to 2.7 hours, with a correlative effect on school performance."

Better Health & Safety

"The health implications of fuel-based lighting are two-fold: chronic illness due to indoor air pollution and risk of injury due to the flammable nature of the fuels used. Kerosene lamps emit fine particles that are a major source of air pollution because they quickly become lodged in the bronchial system and can result in chronic disease and death...In India alone, 2.5 million people suffer severe burns due to overturned kerosene lamps annually...in Benin between 2002 and 2006 ... more than 50% of burn victims brought into hospitals were victims of fires caused by overturned kerosene lamps.

Daily Savings

For consumers with reduced income the opportunity to save daily running cost remain the main driver for investing into solar products. Depending on the type of product return on investment can be realized in 3-6 months already. With a product life-cycle of more than 5 years significant cost savings emerge after this period.




"Kerosene costs vary across the world, but even in countries where kerosene is heavily subsidized by the government, like India and Sri Lanka, the cost of a month’s worth of kerosene can equal between three to five days of income. In Africa this cost burden is often more substantial, with Lighting Africa research and other estimates showing that BOP African households face recurring expenditures on fuels ranging between 10 and 25% of their monthly household budgets."

Economic Growth

Especially in Africa the majority of our end-customers purchase Niwa products for their small businesses first of all. The reasons range from cost savings, ability to stay open longer hours to competitive advantages.

"Several studies in developing countries show that access to proper lighting (of high enough illumination to enable reading and doing household and business-related activities) has significant positive impact on productivity broadly and income-generating activity specifically. For many rural households, for instance, obtaining fuel for lighting can be a time-consuming task that requires traveling long distances and is often undertaken by women and children, reducing women’s available time for income-generating activities... In a recent Malawi study of a solar lantern project, ten percent of lantern buyers – many in very low income brackets – noted that the lantern had provided expanded business opportunities by allowing more time to work at night.



Similarly, recent Dalberg and SEWA research in rural Bihar and Gujarat in India suggests that solar lanterns contribute to longer working hours for occupational groups ranging from traditional handicraft artisans, to textile workers, and livestock herders....Lighting Africa research in Kenya provides further anecdotal evidence for the business impact of improved lighting, though more research on solar-enabled SME retailers and small kiosks is needed: A small non-electrified enterprise near Lake Victoria which received solar lighting saw its revenues increase 60% as a result of being able to better illuminate its wares at night. Vendors of shoes, detergent, and food products at a major Kenyan night market reported upon seeing LED-solar prototypes that they would be able to extend their operating hours by 30 to 50% if this form of lighting became available. They also universally believed that their sales volumes per hour would increase as a result of their wares being more easily seen and more attractive due to better color rendering by white LED sources compared to kerosene lanterns."
