Research on Testing Technology of High-Power Photovoltaic Arrays

With the test on the characteristics of photovoltaic arrays, we can assess the performance of photovoltaic arrays effectively. Its help to the research and development of photovoltaic system. The paper introduces the testing technology of photovoltaic arrays and proposes an algorithm to predict the characteristics of photovoltaic arrays. Using this algorithm method the curve which shows the characteristics of photovoltaic arrays can be established according to the field-testing data under arbitrary temperature and irradiation. The testing technology helps to reflect the actual condition of the photovoltaic arrays.
