Solar rooftops installed on temples and industrial parks in Vietnam have realised a 30 per cent reduction in energy costs compared to a traditional wired solution.

It follows a partnership between analogue and mixed-signal semiconductors and advanced algorithms specialist Semtech and Cloud Energy, an Internet of Things (IoT) solution provider in Vietnam.

LoRaWAN network

The companies have joined forces to develop and deploy a network running on the LoRaWAN standard for a wireless solar power system installed on facility rooftops.

A wired energy solution did not fit a rooftop solar power system due to more expensive hardware and installation costs as well as a higher level of ongoing required maintenance, particularly in rural areas of Vietnam where rodent damage to cabling is a particular issue.

Cloud Energy’s wireless solar power system, featuring Semtech’s LoRa devices and LoRaWAN connectivity, claims to provide comprehensive, accurate and independent data management from inverters, electricity meters and sensors to inform site owners.

According to Cloud Energy, the solar power system solutions saved its customers more than 30 per cent on initial investment for a monitoring system.

“We believe that the future of monitoring solutions will largely adapt to LoRaWAN wireless technology, which is highly scalable, simple to deploy and provides a reliable wireless connection,” said Tuan Anh Pham, Cloud Energy founder.

“Solar power monitoring solutions that use LoRaWAN technology may be a new future trend that not only solves the problem of reliable wireless connectivity, but also provides additional benefits of IoT standardisation, scalability, data analytics, and interoperability.”

The Cloud Energy wireless solar power system is a plug-and-play solution consisting of multiple wireless modules, a Kerlink gateway using LoRaWAN and a Cloud Energy web app to monitor real-time data to review and forecast performance independently across meters, inverters and sensors.

Through the integration of LoRaWAN, Cloud Energy said its solar power system is a true wireless solution offering stable data transmission for end users to manage energy usage across wide areas.

“Cloud Energy’s successful implementation of the LoRaWAN standard for its wireless solar power systems showcases the versatility of the Internet of Things technology to adapt to nearly any setting and budget,” said Marc Pégulu, vice president of IoT product marketing and strategy for Semtech’s wireless and sensing products group.

He added: “The robust connectivity from LoRaWAN is creating smarter buildings for more informed business decisions.”
