As the global movement towards net-zero emissions gains momentum and the European Union introduces its Carbon Border Adjustment Mechanism (CBAM), Taiwan is leading the way in combating climate change by passing the Climate Change Response Act. This act accelerates the transition to net-zero and renewable energy for both public and private sectors. The Taichung City Government is taking active steps to promote green energy and build a low-carbon city. To this end, the Taichung Jianguo Market, the largest public retail market in Taiwan, has built a rooftop solar power system by repurposing the top floor parking lot. The system, which was officially connected to the grid on March 6, is expected to supply electricity to 461 households annually and reduce carbon dioxide emissions by 991.822 metric tons. This is equivalent to the annual carbon absorption of 2.6 Da’an Forest Parks. The initiative is set to inject new life into green energy development and the revitalization of public spaces, creating a nationwide benchmark for public green rooftop projects.

The solar power generation system at Taichung Jianguo Market, designed and constructed by Mingjun Energy, has a total capacity of 1,948,570 kW per year. The innovative rain shelter design, combining H-steel structure and C-beam, allows for the installation of solar modules above it. This design not only improves the building’s service life but also maximizes the usage rate of the top floor parking lot. The project features PrimeVOLT intelligent solar inverters, which are compliant with IP66 waterproof and dustproof standards and pass the salt spray test of the international regulation standard IEC 60068-2-52:2017 severity 5. Even with Taiwan’s diverse climate, the system provides stable operation and excellent power conversion performance. The PrimeVOLT inverter is equipped with four sets of MPPT that can be flexibly configured to optimize power generation according to the different configurations and orientations of the solar panels. Its PF 0.9 real power output without load shedding function can enhance the overall power generation revenue. Additionally, the optional AFCI function can detect arc abnormalities in time, reducing the risk of fire for the system.

FAN Mingchung, Senior Sales Manager from PrimeVOLT, emphasized the crucial role of solar inverters in ensuring the safety and efficiency of solar systems. He also mentioned that at the Taichung Jianguo Market, 22 three-phase on-grid inverters of 60kW have been installed, each embedded with maximum power point tracking technology that can achieve a remarkable conversion efficiency up to 98.6%. The cutting-edge technology fully maximizes the power generation efficiency of the system, ensuring that the rooftop solar power system provides reliable and efficient clean energy to the community.

Heat waves are striking globally, and it is imperative to curb the speed of global warning with the use of renewable energy; how to implement the applications of renewable energy and Net Zero carbon reduction have become important issues that governments and enterprises around the world are now focusing on. Taiwan is on the Tropic of Cancer and has sufficient sunshine all year long, which makes it very suitable for solar photoelectricity development; however, it also often faces the challenge of difficult land acquisition. As a matter of fact, many lands in coastal areas of Taiwan are often abandoned due to subsidence or severe salt damages, which caused them to be geologically unfavorable for farming. The construction of solar farms not only can bring a ray of life to the revitalization of barren lands, neither will it affect the development of normal agriculture; the considerable carbon reduction effects that it can bring due to the renewable energy are also extremely meaningful nowadays when global warming is intensifying.

The Sen Ju Green Energy Solar Farm located at Fangyuan Township, Changhua County is a ground-based solar farm built on such barren lands. The capacity of the devices of this farm is 2MW, and they all use PrimeVOLT’s 60kW three phase on-grid PV inverters. The owner stated that Changhua County has sufficient sunlight, and according to the data from Taipower, the average daily power generation per 1 kW of solar power is as high as 3. 55KWH, which is the highest average power generation among all counties and cities in Taiwan. It is estimated that its investment payback period will be the shortest in all counties and cities in Taiwan; it is extremely economical. More importantly, the annual power generation of the farm is as high as 2. 6 million KWH. According to the statistics of Taipower, the average power usage per household for 2021 was 352KWH, which means that this farm can provide electricity for over 600 households for a year; it can even reduce carbon emission by approximately 1300 tons per year, which is the annual carbon intake of over 3 Daan Forest Park. Because of the construction of the solar energy system on the barren lands that are unfavorable for farming, its actual carbon reduction contribution to the global environment cannot be underestimated.

*Sen Ju Green Energy – Changhua Fangyuan solar farm fully adopts PrimeVOLT’s 60kW smart on-grid PV inverters

This farm is close to the Changhua Wanggong coastal area, where there are strong sea breeze and severe salt damages; the owner specifically chose PrimeVOLT 60kW string solar PV inverters that comply with IP66 waterproof and dust-proof standards and passed IEC 60068-2-52: 2017 severity 5 international salt spray tests. Its salt-proof design can adapt to the special geographical environment of high salt damage in the coastal areas, and fully exert the maximum performances of the inverters. In addition, PrimeVOLT 60kW three phase on-grid PV inverters are equipped with four sets of MPPT that can be flexibly configured according to the different terrains and orientations of the farm, converting the power generation of the solar module more efficiently. The PF 0. 9 real power output with no derating can improve the overall power generation revenue, and the AFCI arc detection function can detect arc anomalies in real-time, reducing the risk of fire for the farm.

That’s worth mentioning is that PrimeVOLT inverters are string type with the features of flexible configuration and easy construction/maintenance. The difficulty for its operation and maintenance is much lower than the more centralized inverters. Whenever there are malfunctions, it is easier to identify the failure point of string inverters; this improves the efficiency for operation/maintenance and saves the cost for maintenance manpower significantly. In addition, the entire series of PrimeVOLT inverter products all have built-in DC junction box functions, there is no need to purchase additional DC junction boxes; it can reduce the construction cost for the farm directly, and shorten the investment payback period of the solar farm, in which the AC/DC surge protector can provide comprehensive protection for the farm to improve the safety of the farm.

PrimeVOLT inverters have won the “Taiwan Excellent PV” award repeatedly from the Ministry of Economic Affairs with their outstanding and high-performance product qualities; higher power and energy-storage models will continually be launched in the future based on market trends and needs. PrimeVOLT will work hand in hand with its various large farm customers across Taiwan to implement energy transition and achieve the government’s goal of Net Zero carbon emission by 2050.

PrimeVOLT is a local PV inverter manufacturer and the company has set a goal of 30% growth each year. Despite the COVID-19 pandemic, customer delays and other variables this year, PrimeVOLT still managed to far exceed its goal of a 30% growth in shipment volumes in the first half of the year. While COVID-19, part shortages and rising part prices are set to bring new risks and challenges in the second half of the year, PrimeVOLT is still optimistic that its total shipments for the year will surpass its annual target.

A battle for supremacy is now taking place between string inverters and central inverters in the inverter market. Jimmy Chuang, General Manager of PrimeVOLT, states that while string inverters suffered from higher initial construction costs, central inverters have one fatal weakness: Any failure results in large-scale outages. Repairs are also difficult and may take anywhere from several weeks to two months to complete.

The development of solar power in Taiwan is now moving from roof-mounted systems to ground-based systems. Initially, some ground-based projects used the centralized model, but there has been a gradual shift to string inverters in line with international practice. PrimeVOLT is continuing to communicate with customers about the need to also look at material requirements, construction costs, future failure rates and operation & maintenance in addition to maximizing the power output of their system.

More and more projects are now turning away from central inverters to optimize overall generating performance and return on investment. Large, medium and small projects are now increasingly dominated by the string type. The full range of string inverter products offered by PrimeVOLT helped the company consolidate its position in the small and medium-sized market, making it the undisputed No. 1 in the rooftop market. Significant inroads have also been made in the large project market, giving PrimeVOLT a clear edge.

In the past, large projects may be enough to move a company several places up the market rankings, and vice versa. The increasing number of ground-based projects means that individual projects will have an even greater impact in the future. PrimeVOLT has been cultivating customers of all types over the years. Having accumulated up to 500 customers over the last decade, it does not rely on a single project site to keep up its numbers. The decision by many large ground-based projects to make PrimeVOLT their preferred supplier in recent years is of tremendous significance as well. (Yung-Chuan, Weng)
