In the previous Meet & Greet, we discussed integrating barometers into renewable energy projects and measurement campaigns. Since air pressure, temperature (T), and relative humidity (RH) impact each other, we usually recommend installing T/RH sensors in combination with barometers to better characterize the local conditions. In today’s post, we will be introducing the advantages of installing T/RH sensors, such as our Galltec TP/KP models.

Why does it matter?

For renewable energy projects, temperature and humidity information have a wide range of influences during the developmental and operational phases. For example, during the development of a wind project, icing conditions and temperature-based curtailment can have a significant impact on energy predictions and turbine suitability. Meanwhile, humidity in the air can be a double-edged sword for solar projects. Acquiring more detail on site conditions during the development stage enables better projections of what the asset experiences during its operational life. In response to this additional data, project design can ensure correct management, optimized productivity, and ultimately, improved ROI.

Location, location, location!

It’s true in real estate, and it’s true with sensors. For T/RH sensors used for renewable energy project design and operation, we recommend these sensors to be measuring near the operating height of the asset and preferably out of direct sunlight, as we aim to remove uncertainty and unrealistic variance that can be induced with long duration full-sun conditions. That said, sometimes we want to know the impact of full-sun conditions, and therefore suggest that you keep this in mind when designing the measurement campaign and sensor setup.

Improve data accuracy with weather shields

Weather and Radiation Shield for Air Temperature / Humidity Sensor

Since direct exposure to sunlight, wind and physical impact from various weather conditions can cause inaccurate readings in temperature sensors or even equipment damage (imagine if it was hailing!), we tend to recommend pairing them with weather and radiation shields. These are designed to protect the sensors from producing faulty measurements and act as a physical barrier while supporting proper ventilation. Since temperature sensors can be installed as high as 120+ metres off the ground, using protective shields can save on replacement and maintenance costs.
