<p>In solar power systems, irradiance value data are among the most important parameters. Such can be used in installing photovoltaic (PV) modules, such as determining exact location, tilt angle, and required area, for optimal efficiency. In this study, comprehensive simulation implementation of a radiation meter with PV cell temperature sensor presented. The measurement is based on readi...

This study examines the association between firms’ environmental, social, and governance (ESG) performance cost of capital for largest European firms listed on STOXX Euro 600 in a large panel from 2002 to 2018. We find that ESG is priced by both debt equity markets, although different directions. While better associated with lower equity, relationship positive regarding debt. also account indus...
