虽然以前的研究涉及住宅光伏系统的可靠性，以改善系统在个人用户和社会中的传播，但很少有人研究用户对自己的光伏系统的看法，这可能包含解决方案，使系统牢固地融入社会。首先，本文考察了住宅光伏系统用户对其自身系统的规格、可靠性和故障风险的了解程度。其次，考察了影响用户对光伏系统满意度的因果因素。通过对鹿儿川市收集的数据进行分析，发现用户对其住宅光伏系统的基本规范了解不足，特别是系统有时会出现故障，因此需要适当的维护。此外，用户对系统财务回报的期望与他们的满意度之间存在很强的因果关系，这在经验上得到了证实。这些结果表明，应该更多地解决过度关注盈利能力和相对较低的对系统可靠性和故障风险的兴趣，以避免可能阻碍这项技术进入社会的问题。
Although previous studies have addressed the reliability of residential PV systems in order to improve the dissemination of the systems among individual users and societies, few have examined users' perception of their own PV systems, which might contain solutions to firmly establish the system into society. First, the present paper examined the extent to which residential PV system users understand specification, reliability, and failure risk of their own systems. Second, causal factors affecting users' satisfaction with PV systems were examined. By analyzing data collected in Kakegawa City, this paper revealed that users did not appropriately understand the basic specifications of their residential PV systems, and in particular, the fact that the systems sometimes failed and therefore needed proper maintenance. Furthermore, a strong causal relationship between users' expectations of financial return from the system and their level of satisfaction was confirmed empirically. These results suggested that excessive focus on profitability and relatively low interest in the systems' reliability and failure risk should be addressed more to avoid problems that could potentially hamper the establishment of this technology into society.
