(Wels, 06/03/2018) A regulated feed-in tariff for solar power has been in place in Vietnam since the end of 2017. For many private individuals and companies, this is an incentive to invest in renewable energies. As a specialist in solar technology, Fronius Solar Energy is supporting system operators in the country with high-quality, easy-to-install inverters and a unique service plan with local partners in the region. Fronius recently supplied inverters for a PV system in Ho-Chi-Minh City, which will generate up to 120 megawatt hours of electricity per year.
The photovoltaics market in Vietnam has enormous potential, with extremely high levels of insolation all year round in the central and southern areas of the country. Despite this, the topic of solar energy is relatively new here; a regulated feed-in tariff was only introduced at the end of 2017. The government has set itself the goal of installing PV systems with a total output of twelve gigawatts within the next twelve years. Fronius Solar Energy has also recognised this potential and is supporting private and commercial system operators with its vision of 24 hours of sun, a future in which 100% of the world’s energy needs are covered by renewable sources. The company’s portfolio comprises innovative inverters and targeted on-site services thanks to the unique Fronius Service Partner programme. “Our Fronius Service Partners have to complete special training courses in which they learn everything about the correct installation, commissioning and maintenance of the components”, explains Hans-Georg Einwagner, Area Sales Manager at Fronius Solar Energy. “This means that we can offer our customers maximum service quality.” As our Fronius Service Partners can perform PC board replacement on the device itself, all systems can be serviced with just one visit. This helps the system operator to significantly reduce the costs of generating electricity using the PV system over its entire service life.
Active Cooling Technology increases the service life of inverters
In addition to smaller systems for private households, Fronius has also supplied the first inverters for a major project in Ho-Chi-Minh City in Vietnam. The roof-mounted system has an output of 76.6 kWp and will generate up to 120 megawatt hours of electricity per year. The main challenge for this project is that the average temperature at the site is over 30 degrees Celsius. In conventional inverters, these high temperatures can lead to overheating of the electronic parts; an increase of just ten degrees Celsius can halve the service life of the devices. To avoid this eventuality, the operators in Vietnam opted for three Fronius Eco inverters. “These inverters have Active Cooling Technology. Fans fitted to the exterior constantly cool the device which extends its service life”, explains Einwagner. Even in regions with high ambient temperatures, the inverters deliver their full output power and maximum yields. What’s more, there are no restrictions when it comes to installing the inverters. They can be fitted flat, vertically or horizontally and are therefore suitable for a range of application areas.
