摘要
A quantitative analysis of the long-term field performance of a photovoltaic (PV) array has been made considering such field variables as solar insolation, temperature and long-term degradation of a solar cell. It deals with (i) the numerical analysis of two degradation factors of a single crystal solar cell, namely, increased lumped series resistance R(s) and decreased short circuit current I(sc), (ii) the field condition V(m) - I(m) relation, and (iii) the ratio of I(m) and I(sc) for a PV array. The value of I(m) has been computed from the solution of a transcendental equation using Newton-Raphson approximation technique. This approach has been verified by field data obtained in Delhi, India, over a period of four years for the single crystal silicon PV modules (manufactured by CEL, India). It can be used for the study of the long-term field performance of a polycrystalline and amorphous silicon PV module.
