Market Research on PicoPV Systems of Lighting Africa

From energypedia

Overview

Lighting Africa is a joint IFC and World Bank program. Its objective is to provide up to 250 million people in sub-Saharan Africa with access to light generated by alternative energy sources by 2030.



Methodology

The research was accomplished by Research International East Africa.

It includes:


  • five products: a table lamp and two flexibly mountable lamps powered by means of small, portable solar panels; one flashlight powered by solar panels; and a second flashlight powered by common batteries.[1]
  • two key market segments: households and micro-businesses in rural and urban areas [2]
  • five countries: Ethiopia, Ghana, Kenya, Tanzania, Zambia


The research collection, which was accomplished in 2008, consists of:


  • Exploratory Qualitative Study. Objective is to gain a first insight on user demands and preferences. As usual in case of qualitative data, results can not be generalized, but provide an in-depth understanding of consumer needs and motivation. This phase includes 55 interviews. Simultaneously each respondent tested an off-grid product. Interviews were accomplished in each of the two market segments.
  • Quantitative Usage and Attitudes Study. This phase aims to quantify users habits and attitudes. Additional questions, which were of keen interest: current expenditures for energy supply, willingness to pay. This phase consits of interviews with 1000 households and 400 small business owners in each country. Interviews were accomplished through structured questionnaires.
  • Product and Concept Testing Study. Objective is to find out new additional product types. Strenght and weaknesses of products are explored. Key questions in interviews were: Who is the Consumer? How does the Consumer use light? How do consumers perceive the products? What does the consumer want? Which products do consumers prefer? How much is the consumer willing to pay? In order to explore success of product launch the following measure was applied: WHAT? Find out, if the consumer understand the product and its use makes a noticeable difference. WHY? Is the perceived difference desirable? WOW? Is the benefit big enough to get over barriers? [3]



Results

Main findings, which overlap in all studies, are presented in the following part:


  • Most people are not connected to the grid, even if it is often within 5 km. If they are connected, grid is often not a reliable source.
  • Better lighting is a wish of first priority in order to improve household, business and their facilities. Most respondents stated, that their current used lighting device is not their preferred one, but that they can not afford an alternative energy source.
  • Light is used for about 4 hours at night. It should last for 6 hours per day minimum (sometimes used in the morning as well)
  • Main living area and bed room are mostly enlightened, while dining area, place for cooking and outside area are often neglected.
  • Due to a lack of awareness of consequences of kerosene and paraffin, most people don't worry about environmental effects of kerosene/paraffin. Additionally, only few people worry about health effects.
  • Businesses mostly use their lighting device only in their businesses and not at home.
  • Kitchen and bathing facilicites are often outside the houses.
  • Lighting devices used most are: kerosene, tin and paraffin lamps.
  • solar lanterns are mostly perceived as product of high quality, but in terms of ease of operation common lamps rank mostly much higher.
  • User of different countries prefer different colors, shapes and designs. Familiar designs or new designs, which are associated with objects with positive images, seem to be preferred.
  • Hours of use as well as recharging process depend more on habits of usage, than on actual battery life.
  • People prefer: long-lasting material, brightness of light, affordability, portability, ease of operation, illumination of large area, a device to stand the lamp on a surface or hang it on the wall, indicator for charging process, a slot for additional applications (radio, TV), safety of charging process (theft).
  • Nearly all people fear the rainy season due to a lack of sunlight to recharge their lamps.

Below are specific findings of each study of the five countries.

Quantitative Study[5]

Households:


  • The majority of Ethiopian consumers are farmers (81%), living in rural area (79%), with an average income of households about USD 115.79. 91% of consumers and 89% of traders are not connected to the grid. Both connected to the grid, experience cut offs at least once a week.
  • 26% of consumers state, that the most urgent improvement is better lighting. Main consequence of better lighting is an improvement for children in order to make their homework (43%). Because this is the first activity, which is stopped due to a lack of lighting in all Ethiopian regions.
  • Kerosene is the major energy source. Preferred type of lighting device are paraffin lamps with glass cover (25%). Solar powered lanterns are preferred by 15%. Quality of paraffin lamps is rated lower than of solar lanterns. Light bulb in socket are rates best in terms of quality. On the other hand ease of use of solar lanterns is rated lower than of paraffin lamps. Flashlight are easiest to handle.
  • The average time light is used is about 3-4 hours. Light is used mainly for the living room, most people need to enlighten two rooms. Lighting device is mainly hung from a hook on the wall (47%).
  • Chatting / socialising (78%) ist the most common activity at night.
  • 39% are limited in their outdoor activites, mainly taking care of livestock (71%) or visiting neighbors (34%).
  • Head of household decides about purchasing and money.
  • However, 96% of respondents don't worry about impacts on health or environment (99%) using paraffin or kerosene.

Micro-Business:


  • Most businessess are rural based (78%), traders are between 25 and 44 years.

Product and Concept Testing Study[3]

Products were evaluated before and after a test phase by consumers.


  • Nearly all products were used for 3 until 5 hours. The average number of hours the product is charged daily is about 1 to 3 hours.
  • Interviewees seem to measure brightness by comparing the new lighting device with their own one. Hence, depending on their lighting device, evaluation of adequacy of light turn out differently: consumers using kerosene lamps evaluate the light intensity good, whereas consumers using home made devices, such as light bulb connected to dry cells, evaluate the light as being weak and inadequate. Thus, last mentioned users even prefer their own lighting devices.
  • users appreciate solar charging systems ("WOW" no running costs, no smoke) , but they worry about the rainy season.
  • portability and light intensity are important features.
  • size of lantern should not be too small.
  • illuminance in different directions is appreciated.
