PV Balance of System Award
HaoSolar Solar Tracking System
HaoSolar was the single source provider of Solar Trackers and CGNPC/Enfinity provided the complete solar solution to the National Energy Adminstration in the winning bid, which utilized all solar tracking technology from HaoSolar. The National Energy Administrations focus was to deliver the FIT Tariff standard that would be used to provide guidelines for future solar subsidies in China. From a technology standpoint, there was no uniform technology that would enable dual use of solar technology.

The technological issues stemmed from either being able to facilitate optical or time tracking, but not both. This becomes an issue as Hybrid technology is necessary so that when solar energy is blocked because of environmental issues such as cloud coverage, snow or other elements, it becomes important to enable optical tracking. Tracking technology allows for 40% greater output with solar. So when energy consumption is encumbered, it has a dramatic effect on the overall output. There are many constraints as to why optical and timing technology cannot be integrated starting with the integration between Oracle Middleware and Java.
Challenge
CGNPC/Enfinity is a central corporation under the leadership of the SASAC with nuclear power as its core business. It is the only clean energy corporation in China which has solar power. HaoSolar developed the Hybrid solar tracking system, which resulted in Chinas largest and first Photovotaic power station. This is the largest solar tracking system to have ever been implemented in Asia. The challenge addressed was the National Energy Administration embarked on establishing the FIT Tariff for PR China.
Problem Solved
HaoSolars Hybrid tracking technology has allowed for 70% greater throughput of clean energy in Solar investments. This
project was the largest clean energy project in Asia from a solar perspective and the only project to use Hybrid technology. By being able to shift from carbon emission production to solar energy production, the benefit is net gain of cleaner environment both for the current and future generation. HaoSolars integration and technological development of the optical and time tracking system will allow greater reliance on solar technology in the future because of the associated return on investment.
Noteworthy The SETT project was the catalyst for solar growth in not just Dunghaung, but for greater PR China. This project is the largest solar project in the country as well as the APAC region. By showing that both the project is doable but also that it is financially viable, it opens the doors for future clean energy projects of similar magnitude. HaoSolar was instrumental in both the design and implementation of the project. By integrating optical and timing technology, which have not been integrated until now, there is a much greater business case to be made for solar technology and tracking. HaoSolars research and design of the Hybrid tracker was the tip of the spear that drove this project. HaoSolar is the only tracking company to build and implement this solution to the market.
Innovation
The other element is the proprietary Siemens PLC software which does not natively have PIPS or AIAs into the other platforms. Technology Solution: One of the major business drivers for this project was related to a limited architecture that did not support CGNPC/Enfinitys future growth. Implementation of SOA provided the scalable foundation required to create and maintain improved product master data without impacting the current solar architecture. Flexible and Scalable Architecture Implementation of Oracle SOA provided CGNPC/Enfinity with the option of integrating most of their spoke systems with the PDH (SOR) in real-time, enabling the organization to execute transactions at a faster pace. This ability to execute environmental transactions allowed for quick response on the Hybrid technology that was implemented. Energy Quality Improved the solar output rate to 74% for all newly-created Hybrid Tracking
SUNNY BOY 3000TL / 4000TL / 5000TL
Communicative, user-friendly and efficient, Sunny Boy sets the standard. A modern graphic display, simplified installation, delivery of daily yield values and wireless communication via Bluetooth fulfill almost any wish.
Systems by using a business-driven rules engine. Prior to go live, SKU data was inaccurate and as a result, many downstream systems, processes and customer-satisfaction issues were present. With the Siemens PLC integration, timing and optical integration, solar output and tracking were increased dramatically. The Hybrid system also allowed for an override of the timing element so that all external factors ranging from snow and wind to the cloud halo effect would be optimized. Efficiency Activities related to managing the new Hybrid system was also minimized as all manual processes of checking and validating solar tracking positioning were now not necessary.
Customer Benefits
This project benefits society in 2 ways. The first it increases overall clean energy output, thereby reducing reliance on carbon producing energy. The second is that with the Hybrid technology in this project, it provides greater incentives and ROI so that clean energy will be financially viable for future investors.
