The Wekraft Irradiance Sensor is part of Wekraft’s professional-grade sensor range, developed for accurate environmental data collection in small-scale renewable energy systems. This photovoltaic pyranometer, based on a reference cell, is ideal for rooftop solar systems and compact installations—especially when used in tandem with wind turbines.
It measures solar irradiance in watts per square metre (W/m²), allowing for precise calculation of the performance ratio (PR) of photovoltaic systems. Designed with simplicity and affordability in mind, it avoids unnecessary complexity while delivering reliable performance.
The sensor features a measuring range of 0 to 1600 W/m². Each unit is tested in natural sunlight using a reference cell certified by the Fraunhofer ISE Institute in Germany. Data is transmitted via a digital RS485 interface using the MODBUS RTU protocol, and the device requires a 5V DC power supply. It integrates seamlessly with the Wekraft Atlas Wind Turbine and Wekraft Wizard, making it perfect for rooftop PV setups, hybrid solar-wind systems, and off-grid applications.
Compact and lightweight, the device measures 118 x 84 x 55 mm and weighs only 0.2 kg. Installation is quick and easy, with full compatibility across Wekraft systems.
Monitor your energy generation with confidence using the Wekraft Irradiance Sensor—purpose-built for the demands of small-scale solar systems across Australia’s diverse climates.

Verified reviews from real Wekraft owners
Your system seems to be user friendly and well made with a good track record.
Now that I have the Chinese turbine on the mast, it's generating interest. One neighbor would also be interested — they have 3 solar panels and only oil heating, and would like wind production for autumn and winter. Germans have also bought 2 houses in this neighborhood as summer cottages and would like wind power too if it works. If I get production, there will be more orders for you.
The Atlas has been running beautifully at our place — quiet, steady output even in light wind, and the MyWekraft app makes it easy to keep an eye on. Really impressed with the build quality.
Hello, I purchased the Atlas 10 kW wind turbine along with the blade set, and it's working perfectly. Assembling the blade set was a bit of a challenge, and a few screws were missing, but everything came together in the end. Delivery took slightly longer than expected, but I’m very happy with the final result. Many thanks to the Wekraft team. You have my full rating — 5 out of 5. I’m already considering buying an inverter as I plan to move fully off-grid. Wishing you all a great day. — Carina Magnus
ordered the first versions of the Wekraft Magnum wind turbines in 2018 for Northern Pole research missions, and they have been generating electricity reliably in some of the roughest conditions on Earth.
I have set up 1 Wekraft vertical 5 kW turbine, 2 small 12V turbines (from China), and a water turbine in my little creek that provides 200W constantly. All were set up by myself. I am satisfied and not planning to sell the Wekraft.
Amazing product, working very efficiently. Impossible to find a similar alternative at this price point. Thank you Wekraft!
