Table 2 Latent variable scales in the PV projects Technical audit with their respective reliability and component items

From: Whistleblowing on photovoltaic operations in Nigeria: panacea for sustainable development

Latent variable scales Cronbach's alpha (reliability test) Component items
Appropriateness for energy need 0.82 1. Solar project is initiated at the appropriate time. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
2. Location of the solar project is appropriate and feasible. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
3. Area coverage of the solar project is appropriate. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
4. Solar project serves the purpose for which it is provided. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
Adequacy in energy efficiency 0.74 1. Energy output of the solar project satisfies the purpose for installation. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
2. Solar project functions efficiently and when it fails repairs come immediately. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
3. Solar project performance is the same with conventional energy powered options. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
4. Experts should mount and maintain such solar projects. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
Sustainability of PV project 0.70 1. There is adequate security provided for the solar project. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
2. There have been varying discomforts associated with the installed solar project. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
3. Solar project is expected to have a long life span. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
4. More installations of such solar project are encouraged. (4-point Likert scale from “Strongly agree” to “Strongly disagree”)
