The 2050 Net Zero carbon emission has now become an international consensus; the National Development Council also published the “Net Zero carbon emission roadmap” recently; energy transition in Taiwan is imperative. Compared to other renewable energies, the development of solar photoelectricity technology started earlier and is relatively more mature by now. To achieve the target of cumulative 20GW solar photoelectricity by 2025 set by the government within a short period of time, it relies on the active deployment of different types of solar farms across Taiwan. In addition to large-scale ground-type farms, construction of solar photovoltaic systems on the rooftops of agricultural facilities is also a target that the government is actively promoting.

The constructions of solar systems on farmlands nowadays are mostly on the rooftops of poultry houses. Take Taiwan’s largest source of poultry and livestock mean production, Yunlin County, for example, the Hua Yin Solar Photovoltaic Power Plant located at Gancuo, Citong Township is a typical poultry rooftop type farm. The capacity of the panel devices at Gancuo is 475. 2kW, which all use PrimeVOLT smart three phase on-grid PV inverters. The annual power generation of the farm is as high as 540,000 KWH, which can be provided for the electricity usage by 150 households for a year, and it can even reduce the carbon emission by approximately 270 tons per year, which is more than the annual carbon intake of one Daan Forest Park.

The owner stated that the Gancuo farm itself built the solar systems on the rooftops of its poultry houses; not only was it because they were interested in the revenue from 20 years of electricity sales, having solar systems built on the rooftops of poultry houses can also isolate the scorching sun and reduce the temperature of the poultry houses effectively. It also prolongs the usage life of the metal corrugated roofing sheets and reduces the chances of water leakage. These are additional advantages for installing solar photovoltaic systems on the poultry houses.

The Gancuo poultry house farm adopted PrimeVOLT’s 30kW/60kW series three phase inverters, in which the 60kW upgraded versions of inverters (PV-60000T-U) are equipped with four sets of MPPT that are able to convert the power generation of the solar modules efficiently; the IP66 and salt-proof designs can also exert their performances under various environments. The 30kW inverters (PV-30000T-U) are products that won the “Taiwan Excellent PV” award from the Bureau of Energy in 2021; their PF 0.9 real power output with no derating can increase the income from power generation effectively, and also increase the overall cost-effectiveness of the product. All series of PrimeVOLT products have built-in DC junction box functions that provide comprehensive protection, and can reduce the construction cost of the farm directly, and shorten the investment payback period of solar farms.

PrimeVOLT a new energy brand of a major energy manufacturer in Taiwan – Asian Power Devices; it has been developing and selling solar photovoltaic converters (inverters) at home and abroad, and its products have won the “Taiwan Excellent PV” awarded by the Bureau of Energy, Ministry of Economic Affairs. PrimeVOLT specializes in string inverters; compared to centralized inverters, centralized inverters may have lower construction costs during the earlier periods, but in terms of benefits from long-term investments, which owners cares most about, string inverters have advantages including flexible configurations, easy construction and maintenance, and low assembly cost. When malfunctions occur at the farm, the failure points are easier to identify, allowing repairs and maintenance to be more efficient, and saves maintenance cost significantly. The advantages and disadvantages of investment benefits for the long term can be seen immediately; string inverters are still the best choice for the investment in different types of farms.

The Taiwan Excellent PV award held by the Bureau of Energy has entered the ninth year this year, and this year, inverters were included in the competition for the first time; it is the highest quality award for the inverter industry. The major inverter manufacturer, PrimeVOLT, participated in the competition with its three phase inverter series and won the award. The award was presented by the President Ing-Wen Tsai on the 8th, and the General Manager of PrimeVOLT, Chin-Ming Chuang, received the award.

The “2021 Taiwan Excellent PV” award was reviewed according to the national standard (CNS) of the Republic of China (Taiwan); the review contents include the parallel verifications of the inverters, the verification of safety specifications, and the verification of electromagnetic compatibilities, etc. In addition, it was confirmed that the products can adapt to rigorous environments according to the US ASTM B368-09 Copper Accelerated Acetic Acid Salt Spray (CASS) high corrosive test item, and the inverter that is most suitable for the island-type special environment of Taiwan was selected. Most large-scale solar power plants are constructed on salt flat lands in recent years; the high salt environment and the intertidal impacts are rigorous tests to power electronic equipment; general salt spray tests could no longer verify its adaptability.

The PrimeVOLT inverter that won the award is a one-piece aluminum casting box with IP66 dust-proof and waterproof levels, and passed IEC 60068-2-52: 2017 severity 5 salt spray test; it is suitable for use in Taiwan’s island-type humid and rigorous environments. The two sets of MPPT can input independently or in parallel; the built-in DC junction box function has features including PF 0.9 real power output without derating. The design of the appearance also won the Golden Pin Design Award awarded by the Industrial Development Bureau, Ministry of Economic Affairs.

Energy Taiwan will be exhibited at Taipei Nangang Exhibition Center, Hall 2 from 12/8-10, PrimeVOLT will also showcase its latest smart solar photovoltaic inverter series. Chin-Ming Chuang stated that PrimeVOLT inverters won the Taiwan Excellent PV award, which shows its product strengths, and they comply with industry trends. The new inverter products displayed this time are equipped with AFCI (Arc-fault circuit interrupter) arc detection functions that can detect abnormal statuses of the solar power plants automatically, reducing fire and electrical shock hazards and improving safety. The input current is increased to 12. 5A to satisfy high-performance module configurations, and are equipped with nighttime reactive power compensation, meeting the needs of Taipower’s large scale solar power farms. They also support 380V three phase three wire and three phase four wire power systems, which makes wiring more flexible, in which the 22kW inverter is equipped with fan-less natural cooling design, making it more suitable for poultry and livestock house farms.

The new 75kW function upgraded version even leads the industry and is the first to obtain 440/460/480Vac output voltage VPC certificates, suitable for different power environments; it can reduce construction costs of solar power farms, and are more suitable for applications at large-scale power plants, factories and other special power environments.

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)
