What Solar Professionals need to know: Use site-level weather data to solve power loss problems.

Typical utility-scale PV installation.

An improved power forecast can be achieved when performance analysis of a PV plant starts to account for losses due to localised weather conditions. Elements such as air temperature, wind speed, humidity and rainfall are all known to affect solar plant efficiency.

Our offer: 
National or regional weather predictions cannot be solely relied on for site specific solar tracking power forecasts or high wind safety settings. We offer a MetPak Pro weather platform and MaxiMet compact weather stations for monitoring in real-time the weather parameters that are known to affect PV performance.

Next week we will be exhibiting at Solar Power international 2019, join us on our booth #5450 from 23-26th September 2019.  Dan Armistead, our Technical Support Engineer and our Business Development Managers, John Crilly and Shaun Mason, will be presenting our MetPak Pro multi-sensor weather platform,  MaxiMet GMX541, along with ultrasonic wind measurement products and accessories.

If you are not able to make the show or would like to find out more about our solar product range beforehand, visit our new solar microsite

Gill's WindSonic range of 2-axis wind sensors are popular because of their high accuracy, low cost and excellent reliability. WindSonic now offers even more with WMO-compliant gust measurement.


MaxiMet Marine GMX260 has been added to Gill's latest range of high performing marine weather stations.


Latest generation anemometer demonstrates high performance under extreme conditions


WindUltra, Gill's latest high performance wind sensors, are proving to be market leading on a number of fronts:


MaxiMet now has extended performance in freezing conditions due to the new heated option.


Fantastic achievement by Saildrone to gain a Guiness World Record for the highest wind speed recorded by a USV. We're very proud to say they chose a Gill WindMaster 3-axis ultrasonic anemometer as part of their Saildrone platform to measure wind speed and direction.


We are very pleased to announce that Gill Group has been shortlisted in the Supply Chain Excellence category of the Manufacturer MX Awards 2023!
