Abstract

Energy plays a vital role in the socio-economic development of any nation. Nevertheless, many people do not have access to modern energy services for lighting or other applications. Solar lamps are an innovation of modern lighting services for low-income households. In spite of the benefits associated with the adoption of solar lamps there have been few attempts for the diffusion of this technology among South Africa residences. The objective of this study was to assess perceived characteristics of solar lamps from persons in non-electrified households in Khayelitsha, Cape Town (South Africa). Such households rely predominantly on paraffin lamps and candles for lighting. The authors wished to assess public perceived characteristics of solar lamps (relative advantage, compatibility, complexity and affordability in a preliminary persuasive stage). Primary data was collected through use of a structured questionnaire (respondents completed 26). Each response - from `strongly disagree' to `strongly agree' received an integer score of 1 to 5. In addition, data reliability was determined by using Cronbach's Alpha. Results indicated most respondents perceived solar lamps as more advantageous, compatible and affordable than paraffin lamps and candles. Answers swayed more towards `disagree' on the complexity of the technology. The values of alpha ranged from 0.46 (for affordability) to 0.84 (for relative advantage, indicating solar lamps had a significant perceived relative advantage over paraffin lamps and candles.

卡耶利察太阳能灯感知特性的评估

能源在任何国家的社会经济发展中都起着至关重要的作用。然而，许多人无法获得照明或其他用途的现代能源服务。太阳能灯是为低收入家庭提供现代照明服务的一项创新。尽管采用太阳能灯有很多好处，但在南非住宅中推广这项技术的尝试很少。本研究的目的是评估开普敦(南非)Khayelitsha非通电家庭中人们对太阳能灯的感知特征。这些家庭主要依靠石蜡灯和蜡烛照明。作者希望评估公众对太阳能灯的认知特征(在初步说服阶段的相对优势、兼容性、复杂性和可负担性)。主要数据是通过使用结构化问卷收集的(受访者填写了26份)。从“非常不同意”到“非常同意”的每个回答都得到1到5的整数分。此外，采用Cronbach’s Alpha法确定数据的信度。结果表明，大多数受访者认为太阳能灯比石蜡灯和蜡烛更有利、更兼容、更实惠。对于这项技术的复杂性，回答更倾向于“不同意”。alpha值的范围从0.46(可负担性)到0.84(相对优势)，表明太阳能灯比石蜡灯和蜡烛有明显的相对优势。
