Abstract :
In this study, to be able to measure 900 Wp solar panels in partial shading using cardboard media with intervals on solar irradiation which is very much needed in measuring solar panels and also measuring partial shading and knowing how to retrieve data in real-time in analog form when measuring 900 solar panels Wp. This research also aims to create a 900 Wp solar panel monitoring system for the partial shading effect with cardboard media and implement it on cardboard media so that you get results from partial voltages when it takes place. In this research it is necessary to conduct a Literature Study by gathering information related to the topics taken in this study. Learn basic theory about monitoring and controlling 900 Wp solar panels on partial shading with cardboard media and Tool Analysis Testing. Conducting an assessment of the 900 Wp solar panel monitoring system on partial shading with cardboard media to determine analog parameters and numbers when measuring using an avometer. Therefore it can be concluded in this study to be able to evaluate the final stage of synchronization in the program and the results of monitoring testing of 900 Wp solar panels on partial
shading with cardboard media. This is also the need for electricity through solar energy in accordance with what is needed in the home industry for the production of hand-drawn batik in Tanjung Bumi in the village of Peseseh, Bangkalan-Madura.
