3 Pixel View We offer the Billion Watts Pixel View, a professional solar monitoring system, for users to manage and monitor solar farm by providing detailed string-level information on the universal management platform. We assist solar farm administrator, asset manager and investors to identify places to decrease failure and improve the overall power generation and equipment operation efficiency. High Accuracy Resolution String-Level Monitoring Real-Time Cloud Management Data-Oriented System A Strategic Tool to Optimize Solar PV Productivity Efficiency and Asset Management. With the technology advancement, the PV solar has increasingly become the most cost-effective long-term investment. Like any equipment, solar power system needs to be well managed to maintain the optimal electricity productivity efficiency. Therefore, we provide Pixel View, a data-driven, Web-based intelligent PV monitoring software system, which can transform the PV O&M (Operation & Maintenance) from a manual, complicated procedure into a simple, scalable, and effortless enjoyment to ensure the best solar yield at all times. 3

4 Prevent the Damage of Shading Effect The general solar generating system is combined with various solar modules in different series in parallels to accumulate the sufficient voltage and current. A partially shaded solar module by dust, snow, leaves, adjacent building shadow or even bird dropping may result in significant decline in power generation down to 25%. Pixel View can display the most up-to-date performance data of each PV combiner boxes and inverters, providing power plant owner, project developer, utility, and independent power producer (IPP) a user-defined platform for monitoring power generation status in real-time and to further prevent permanent damages, such as hot spot and cell-crack. High Compatibility, String-Level Monitoring Pixel View is compatible with all brands of inverters and solar modules that can collect and analyze detailed PV generation data down to string level and AC power converted by inverters. Through Pixel View monitoring portal, the administrator can remotely monitor solar energy collection and convergence process effortlessly. 50% 50% 50% 50% 50% 50% Unable to identify abnormal string location 97% 97% 97% 97% 97% 97% Pixel View Inverter Solar Management System Traditional solar monitoring system Pixel View solar monitoring system 4

5 Embrace Our Prosperous Solar Future The traditional solar monitoring system can only indicate the underperformance of solar system. The central console needs to send the professional technicians on site and inspect solar modules individually, which is time-consuming and costly. By utilizing Pixel View, the administrator can identify the particular solar module series that can dramatically decrease the cost of maintenance & operation personnel.

9 Traditional Solar Monitoring System VS Pixel View Safety Pixel View can not only monitor the voltage and current of each string, but also send out alarm notifications when the system detects any underperformance, failure, or malfunction, which significantly reduces the danger of electricity leakage and electric fire due to short circuit incidents. Monitoring The robust software system can immediately diagnose the cause of any unusual electricity event to minimize the traditional manual inspection costs by increasing the O&M efficiency of power plants maintenance. Operation & Maintenance Pixel View features floor plan functionality that can clearly locate and display the abnormal solar modules to accelerate the intelligent diagnostic analysis. Technicians and maintenance personnel only need to repair or clean a particular region of modules to catch the golden 30-minute system repair time. Immediate Judgement for Shading Effects The output of cells declines when the panel is shaded by a tree branch, snow, dust, or building shadow. Since solar cells are connected in series, the shaded cell will cause a decrease in current output on a particular region of solar panels, which directly influence the current output of the entire series and drop the serial productivity. Pixel View can help users to determine when shading effect occurs and react promptly, effectively preventing permanent overheat damages to the system. 9
