India’s largest and most influential energy expo, Renewable Energy India Expo (REI India), will open its doors on 23 September. This year’s venue will be the India Exposition Mart in Greater Noida. Being a solar resource-rich country, India is on the ambitious path to implementing the world’s largest renewable energy expansion program. Reason enough for the OTT HydroMet Meteorological Division, represented by Kipp & Zonen and Lufft, to seize the opportunity to participate in this key event. We hope to see y

About Renewable Energy India

Over the years, REI has been established as the most comprehensive, reputed and Asia’s largest expo in this domain where the green community congregates to discuss the trends, addresses challenges and showcases the best and most innovative technological solutions available to overcome them. This year the event will once more bring together decision makers and influencers as well as technical experts and professionals from leading companies involved in the renewable energy generation, transmission and distribution to regulatory framework and its challenges.

OTT HydroMet represented by Kipp & Zonen and Lufft

At REI India Kipp & Zonen will represent OTT HydroMet together with Lufft. Kipp & Zonen is known as the market leader and expert in solar irradiance measurement thanks to the well-known CMP and SMP pyranometers. Lufft was the first manufacturer of compact weather stations that can measure all weather parameters using one single housing. Our combined know-how and experience enables us to offer complete solutions for your applications. At REI India our expertise will be at your disposal and our high quality measuring instruments will be on display.

By way of illustration a selection from our measurement solutions is described below.

All weather conditions and soiling monitored

The combination of Kipp & Zonen and Lufft products has resulted in the ‘perfect set-up’ for determining the actual impact of environmental conditions on solar power generation. This perfect set-up combines instruments for the measurement of GHI and POA irradiance, wind speed and direction, air temperature, module temperature and soiling. 

We offer measuring instruments for all weather parameters that effect your plant’s performance ratio. Our smart pyranometers, compact weather stations and DustIQ soiling monitoring system can send all data directly to your site management system, using the Modbus® communication protocol.

WS600-UMB Smart Weather Sensor

WS600-UMB Smart Weather Sensor is a compact all-in-one weather sensor with integrated ventilated radiation protection for measuring air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, air pressure, wind direction and wind speed.

Highlights of this Smart Weather Sensor are: all-in-one weather sensor, low power, heater, aspirated radiation shield, maintenance-free operation and an open communication protocol. WS600 has various interfaces, i.e. RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, XDR and SDI-12.

DustIQ, the revolutionary soiling alert system

As you are no doubt aware, soiling is a big problem for solar plants as it has a great impact on the plant’s performance. Cleaning all the arrays of PV panels of an average solar plant is a labor intensive and costly exercise, even if you use an automated robot system. Until now you had no other option than to clean your panels at regular intervals. But now there is DustIQ!

DustIQ enables you to schedule a cleaning run when it is most beneficial and cost-effective. DustIQ is a smart solution, especially in comparison with traditional systems with a reference PV panel that needs to be kept clean all the time. A clear benefit of DustIQ is that it does not require any maintenance; just clean DustIQ when you clean the arrays of solar panels it is monitoring.

GHI and POA pyranometers

Knowing the solar irradiance, both horizontal and tilted, is key to decision making in asset management and O&M. Our Smart pyranometers are a perfect match for solar energy systems as these instruments have digital signal processing and interfaces optimized for industrial data acquisition and control systems. 


Last but not least we would like to draw your attention to our innovative, user-friendly and affordable all-in-one measuring solution, RaZON+. It's a turnkey solution providing all components of solar irradiance, such as Direct Normal (DNI), Diffuse Horizontal (DHI) and calculated Global Horizontal (GHI), as well as sunshine duration. Particularly interesting features of RaZON+ are the maintenance free Gear Drive sun tracker and the anti-soiling Smart pyrheliometer design. For more details please check: 

The Kipp & Zonen portfolio also includes solutions such as the SOLYS sun tracker equipped with CHP1 or SHP1 pyrheliometers , constituting a rugged all-in one solar radiation monitoring system.

Particularly for commercial rooftops we designed the RT1 PV monitoring system. Find out more at REI Expo.

Welcome to the OTT HydroMet booth!

We hope you’ll come along and visit our booth. We are open to your questions and we would be happy to help you select the best possible measurement solution for your particular application. We’d highly appreciate it if you would share your insights on solar radiation measurement and on any other weather parameters with us. Your feedback is what we need to meet your present and future requirements and the expectations of the renewable energy industry.
