Knowledge, Understandings and Attitude in Management of Expired Solar Cell

Abstract

This work aims to study the public knowledge, understandings, and attitudes in management of expired solar cells. The respondents consist of 389 people from Thammasat University and 47 personnel in the solar cells management field. The result shows that most of the respondents from Thammasat University have good understandings of how to manage expired solar cells (82.01 %) and agree with the proposed method of managing expired solar cells (83.80 %). The respondents agree that mishandling of the unused or expired solar cell panels affects environment and human health. Therefore, it is necessary to focus on manage of expired solar cells and the government should also set up the clearly laws regarding the discard of solar cells. Results from the study show a moderate level and statistically significant positive correlation between knowledge, understandings, and attitudes (r = 0.419, p< 0.001). In case of respondents whose background are in the solar cells management field, high attitude level was 85.11%. The management of expired solar cell panels should start from the point of origin to the end point. In addition, the management of expired solar cell panels should be governed by the electrical and electronic equipment regulations (WEEE).
