As experience with other renewable technologies show, lack of social acceptance and incongruity with cultural values and norms are common barriers during the implementation phase. Therefore, it is important to investigate in users needs and behavior patterns. Additionally, experience show, that laboratory test have to be complemented with fied tests in order to test the solar lanterns under real-life conditions. Due to the fact, that many bad quality products exists, it is important to test selected products in a field test.



GIZ Energising Development has conducted various tests in different countries, such as Bangladesh, Bolivia, Ethiopia, Mozambique, Nicaragua, Peru, Senegal and Uganda. Approaches of these tests differ, results and outlook are presented within this articles.

The GTZ PicoPV country survey results underpin that an ‘all-size-fits-one’ lamp model does not exist. The lamp models were rated differently by users across different continents, and they were liked and disliked for different reasons. However, there are some aspects that turned out to be important for consumers in all the test countries.

Above all, light quality, including the size of the light cone and light intensity, mattered most to the majority of respondents. Apart from that, in Latin America it was the radio function that made people like certain lanterns, whereas for African consumers the phone charging function was considered more important. Another selling point for lamps in Uganda was visual resemblance of the kerosene lanterns that are conventionally used there. For these reasons, people felt that the solar lamp could directly replace the traditional model and therefore perceived it as particularly useful and relevant.

Another result that emerged from the research was that consumers are highly suspicious of poor quality products that have only a short lifetime. Even among poor households there is a willingness to pay for quality, and there is evidence that the target consumer groups do think ahead and are not interested in products that may be relatively cheap but have to be replaced after a short time. There is also concern among all potential retailers that maintenance and repair services may be a major hurdle towards the development of PicoPV markets in rural areas, where there is no local expertise on these new kinds of products.

The field survey also revealed certain reservations by different consumer groups against some visual design features that will have to be taken into account for any successful PicoPV marketing strategy. For example, people had very particular positive or negative associations with certain colors or forms which might have an impact on their purchasing decision even though they said that these product features were not decisive factors. One lantern, for example, reminded Ugandan women of a camera, which limited its attractiveness, while in Nicaragua people particularly liked the handy format of the lamp.

Result from Lighting Africa Market Research - Monthly average running costs per household for different lighting devices (US$)
kerosene candles batteries
Ethiopia 4.2 0.3 0.9
Ghana 5.6 1.4 2.3
Kenya 10.9 0.8 1.4
Tanzania 7.5 1.5 2.3
Zambia 8.2 4.7 2.3


As part of the baseline analysis of the GTZ field surveys, households were asked to specify their monthly expenditures for conventional lighting devices, whereas the ex-pot survey assessed to which degree the PicoPV lamps had replaced the use of these traditional lighting devices. The finding across countries was that PicoPV lamps have a true potential to substitute conventional lighting sources to a large degree. The associated substantial savings (and poverty alleviation)potential through the use of PicoPV lamps is underpinned by both the GTZ field survey data on lighting costs and the respective Lighting Africa Market Research results from the large-scale household survey in part II of the research project (n=1000 for each country).

Besides the studies mentioned above, market research on PicoPV systems is limited and has so far focused on lighting appliances such as solar lanterns. As rural customers expect more than only light but also other energy services as mobile phone charging or radio, existing studies could be seen as somewhat one-sided.

Kenya (ITC) In a study conducted by ITC in Kenya in 1998 people in urbanand rural areas were asked for what purpose they would use solar lanterns: The main priority was given to (1) ambient lighting in households. This was followed by the desire for (2) studying and reading, using the light to (3) conducting housework during the dark hours and improving the (4)perceived security by having bright light in or in front of their houses. The least importance was given to (5) business. If only rural areas had been taken into account security would have had the lowest ranking (ITC, 1998). The ITC survey was the first step to discover what customers would expect from their solar lantern. Out of these findings the “Glowstar”-lantern was developed.

India (Stanford University) A survey (Stanford University 2003) which summarises experience from various states of India indicates that the rural population uses kerosene to a large extent for lighting of approximately 2-4 hours per day. Given that 60% of India’s population live in rural areas, there is a vast market potential for PicoPV, which can cut household energy expenses by replacing fuel-based lighting. The survey also found indication of demand for PicoPV among those parts of the Indian population which have access to the grid, as power supply in most rural areas is highly unreliable. PicoPV may serve as a back-up during power outages for this consumer group which is marked by higher income levels and has a demand for higher quality energy services. The survey also brought to light that most target customers would not be willing to pay 100% up front in cash for purchasing a system. However, these results vary extremely between various regions. Some of the interviewed groups would prefer some form of microfinance option through retailer financing, village co-operatives or saving groups.

Tanzania (GTZ) From GTZ experiences in Tanzania, it has been observed that customers prefer to have a switch installed in the house rather than a portable system. Even if it provides only very basic services, there was a preference for small solar home systems at least if they are affordable. Furthermore, a disadvantage of portable systems has been that they can be stolen easily in comparison to a fixed system in the house. A crucial point has also been the recharging of solar lanterns. As they are usually placed outside and oriented to the sun in the morning and remain in the same position throughout the day, the full charging potential cannot be achieved.

 

Worldbank's Lighting Africa has accomplished as well a field test with PicoPV systems. A summary of their report is given in this article.
