The Brazilian power grid reaches approximately 99% of the country’s population. To connect the remaining 1% has been challenging – often located in isolated communities of regions that are difficult to reach. With increasing global adoption of solar+storage, and significant price drops across the two technologies over the past decade, the solution is showing promise for the remote Brazilian market. Solar+storage is becoming a more competitive solution than its most popular alternative – diesel – to supply the needed power for off-grid communities. And now, even grid-connected residential properties are opting for independence.
The new president of Huawei’s Smart PV Business Unit, Chen Guoguang, talks to pv magazine about his new role in the company and the future of his division. Increased investment in smart PV R&D and technological innovation are at the top of the agenda. The intelligentization of energy products is also a priority, with much to be gained from the integration of information and communications technologies (ICT) and energy.
Set out on a path to make a difference in the world’s energy future, young entrepreneur David Ding started Growatt a decade ago at the age of 30. Since then, his company has moved quickly to become one of the largest rooftop inverter manufacturers in the world. High in energy and swift to make bold moves, Ding is on a mission to shift the role of user-side solar generators – to become active participants of the new energy future.
Over the next five to 10 years, renewables will assume a larger role as a main power source for electric grids, and PV has a particularly bright future. Considering the latest trends in power electronics technology, PV is quickly evolving down the path to intelligence. Given the rapid development of emerging information and communication technologies (ICT) – such as AI, cloud computing, big data, and 5G – Huawei has an idea of what’s in store for the future of solar PV.
U.S.-owned business intelligence firm Wood Mackenzie has attempted to evaluate the market opportunities offered by the repowering of solar projects around the world which feature inverters which are 10 years old – as well as those which will expire ahead of time.
Seven PV module manufacturers – including JinkoSolar, Longi and JA Solar – won supply contracts this week in a 3 GW procurement round held by China National Nuclear Corp. Flat Glass revealed plans to raise $282.6 million to expand production, while the National Energy Administration reported growth in the residential PV segment.
The 1500V inverter solution has an efficiency of 99.0% and a European efficiency of 98.7%. The inverter relies on temperature controlled forced air cooling technology, integrated zone monitoring, and MV parameters monitoring function for online analysis and trouble shooting.
