The Wekraft Irradiance Sensor is part of Wekraft’s professional sensor range, developed for intelligent environmental data collection in small-scale renewable energy systems. This PV pyranometer, based on a photovoltaic reference cell, is specifically designed for residential rooftops and compact solar installations—especially when used alongside wind turbines.
It measures solar irradiance in watts per square metre (W/m²), enabling accurate calculation of the performance ratio (PR) of PV systems. The design focuses on simplicity and affordability, avoiding unnecessary complexity while ensuring dependable measurement accuracy.
The measuring range is from 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 sensor operates with a 5V DC power supply. It is fully compatible with the Wekraft Atlas Wind Turbine and Wekraft Wizard, making it ideal for rooftop solar, hybrid PV-wind systems, and off-grid applications.
The unit measures 118 x 84 x 55 mm and weighs only 0.2 kg. Installation is quick and straightforward, and integration with Wekraft systems is seamless.
Monitor your energy production with confidence using the Wekraft Irradiance Sensor – purpose-built for small-scale solar setups.

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!
