Electrical and thermographic characterization of a photovoltaic generator of 1,3 MWp

Abstract

This article is about the experience of the solar energy research center, Santiago de Cuba, in the field of characterization of photovoltaic generators. The results of electrical and thermographic evaluation are presented in a sample of 101 photovoltaic modules Si- polycrystalline, power 240 Wp, installed in the photovoltaic array of 1,3 MWp, after a year in the operation. The real value of the evaluated power presents a deviation of average power at standard test conditions of 7,57%, below its nominal value, the most significant being that the electrical power of 7 of these photovoltaic modules, which represents 6,93% of the total assessed is below 90% of its nominal value. The thermographic study yielded 28 modules with problems, including 11 in minor condition, 13 in serious condition and four in critical condition. Aim and approach used: Electrical and thermographic characterization of a photovoltaic generator of 1,3 MWp.
Scientific innovation and relevance: From the measurements performed, the actual value of the selected sample's power is 22,40 kWp, with this value being 7,57% lower than its nominal value. Results or preliminary results and conclusions
