Omniflow has developed a line of hybrid solar street lights. It offers optional solutions to integrate for security, phone charging and Internet of Things applications.
Portugal-based outdoor lighting technology specialist Omniflow has launched a flexible street lighting system that integrates wind-solar energy generation. In addition to providing lighting, the system, which is typically connected to the electrical grid, can be adapted to provide wireless internet connectivity, surveillance systems, Internet of Things applications or even electric vehicle (EV) charging.
Its flagship street lighting product line, Omniled, is a hybrid solar PV and wind turbine system. It is equipped with 22% efficient Sunpower Maxeon interdigitated back contact (IBC) solar cells, a maximum power point tracking charge controller, a wind generator, a fixture embedded with light-emitting diodes (LEDs) and batteries.
The street lights are programmed to use renewable energy first before switching to the electricity grid. The company says this feature reduces grid power consumption, especially when configured with its own energy-efficient LED arrays. Integrated motion sensors can automatically adjust light intensity to further reduce energy consumption.
“Typically, our projects range from a small parking lot with 10 to 20 posts to areas with more than 200 units,” says Pedro Ruão, founder and CEO of Omniflow. pv magazine. Typical installation locations include public parks, parking lots, marinas, recreation centers and hiking trails. The company has also completed off-grid lighting projects.
The Omniled 7 measures 1.20 m x 0.30 m with a mast height ranging from 6 m to 12 m. It has a 60 W solar power and a 100 W wind power and a 500 Wh battery.
The batteries are charged by wind and solar energy. They have a temperature range of -20 to 60 C. When fully charged, the unit controller stops the wind turbine system. The entire system has a 2-year product warranty with optional extended warranties.
The smaller model, Omniled 35, measures 0.60 x 0.15 m and varies in height from 3 to 5 meters. It has 15 W solar energy, 15 W wind and a 172 Wh battery.
The Omniled 7 fixture delivers 5,100 lm to 25,260 lm, while the smaller model has a range of 2124 to 7368 lm. The system has an IP55 housing.
The systems are equipped with adaptive protection response circuits for storms and high winds, as well as operational data loggers for monitoring and management.
Founded in 2012, Ominiflow has 32 patents granted and one pending for EV charging applications, according to Ruão.
Other features that can be added to the basic lighting systems include air quality monitoring, traffic analysis, monitored parking, security and perimeter monitoring, as well as wireless internet connectivity and EV charging. Retrofit sets are available for existing masts.
