You should be able to obtain an I-V (current-voltage) curve for each photovotaic panel that you buy, You can in the UK at any rate. They are supposed to be individually tested so that people doing large installation projects can match the exact preformance of the modules when deciding how to connect them together. Differences in performance of photovoltaic panels coneected in series can reduce the performance of each panel in the series to that of the lowest performing module so the data can be very useful and important. Have your modules come with I-V curves?
