Why Monitor Renewable Energy Plants?

Ground Mounted Solar Plant

Rooftop Solar Plant

Wind Farm

Renewable energy sources are inexhaustible and abundant unlike coal and natural gas which have limited reserves. Renewable sources of energy also provide security to countries of all size from global geopolitics. Finally, renewable is a clean source of energy, a much-needed relief our planet needs on an urgent basis.  
 
The wide adoption of renewable energy depends on the commercial viability of solar and wind projects. Utility-scale projects require major capital investment. The return on this investment can be ensured with continuous monitoring of plant performance.
 

The energy generation from Solar and Wind power plants is dependent on the atmospheric conditions. Aeron’s Weather Monitoring System is a perfect product for real-time monitoring of environmental conditions and thereby for keeping track of plant efficiency on a real-time basis.

Weather Monitoring System for Renewable Energy Plants
Aeron offers a highly versatile, scalable, and reliable Weather Monitoring System (WMS) for Solar and Wind power projects. The WMS uses high accuracy sensors for the measurement of radiation, albedo, wind speed, wind direction, air temperature, humidity, module temperature, soiling, and other parameters. There is a wide range of sensors available with us for selection from global sensor manufacturers.
 
We are aware that the projects of different sizes have different requirements and one size fits all approach does not work. Therefore, we research and test a large number of sensors before recommending you the most optimum combination from the performance as well as the cost point of view.  
 
The weather sensors connect with a high-reliability data logger manufactured by Aeron for precision and reliable data collection from the sensors. The logger applies intelligent software filters on the collected data to remove noise and errors. The data is stored in the logger and communicated on wired and wireless mediums.
 
The logger offers 4G and Wi-Fi for wireless data communication and Ethernet, RS485 MODBUS options for wired communication to SCADA and RTU. There is a range of data loggers and gateways available from Aeron suitable for your project from KW to MW size. 
 
Aeron’s Weather Monitoring Systems have been installed in over 16 GW of Solar and Wind power projects globally and it is a preferred choice of major developers and EPC companies.

Sensors In Weather Monitoring System
Custom Image

Pyranometer

The pyranometer measures solar radiation available at the project site. The irradiance measured by the pyranometer is an indicator of the solar energy available for generation.  Generally, a minimum of two pyranometers are used in every project, first is installed at a horizontal level to measure Global Horizontal Irradiance and the second at an inclination, the same as the solar panel inclination for the measurement of Global Tilt Irradiance. The ground-mounted, also called Utility-scale solar power plants use a thermopile based secondary standard pyranometer for accurate measurement.   

Custom Image

Soiling Station

Solar panel's energy output reduces because of the accumulation of the dust on the panel surface. This loss of energy due to soiling is measured using Soiling Station.
Custom Image

Module Temperature

The energy output from a solar panel depends on its temperature. Therefore, the measurement of module temperature is important for the estimation of the plant performance ratio. The module temperature is measured at multiple locations in the plants, typically at every block level or more.  
Custom Image

Barometric Pressure

The barometric sensor is used to measure the atmospheric pressure at the location of the solar and wind energy plant. 
Custom Image

Wind Speed and Wind Direction 

The wind data is very critical for the wind farms because the energy output is dependent on the wind speed. The wind at the solar project site affects the temperature of the solar modules which in turn affects the energy output. Therefore wind data is useful for solar as well as wind energy plants.

Custom Image

Rain Gauge

The rain gauge measures the rainfall at the project site. The rainfall data helps in better estimation of the annual energy generation. This data is also sometimes used for the insurance of the power plant.  
Custom Image

Air Temperature & Humidity

The ambient temperature and humidity affect the heating of the solar panel and thus affects the energy generation. In wind farms, the heating of the wind turbines is dependent on the ambient conditions. Hence this data is important for renewable energy plants. 

Custom Image

Cloud Cover Sensor

The cloud cover sensor measures the cloud height and cloud base. The presence of the cloud at a solar project site adversely affects the energy generation. The cloud cover data helps in the better estimation of energy generation. There are different types of cloud cover sensors available for use in solar power plants.

Irradiance Sensor

Rooftop solar projects, owing to their small size generally use a silicon-based irradiance sensor to measure the solar radiation but unlike Pyranometer the reference cell needs to be matched with solar panel material for accurate results. Also, it is cost-effective in comparison to Pyranometer. The rooftop solar projects also deploy second class pyranometer in some cases.

Module Temperature

The energy output from a solar panel depends on its temperature. Therefore, the measurement of module temperature is important for the estimation of the plant performance ratio. The rooftop solar projects generally use one module temperature with the weather station.

Wind Speed and Wind Direction 

Wind data is very critical because the energy output in a wind energy plant depends on wind speed. Also, the wind turbine operation is permitted within a specified range of wind speeds. The anemometers for Wind Farms are generally installed at 3 different altitudes on the wind turbine tower.

What Are Bi-facial Solar Modules?

July 10, 2019

The energy output of a photo-voltaic solar plant is closely linked to the efficiency of the solar modules using which the solar panels are made. It is needless to mention that numerous designs and configurations are being developed and tried out to further enhance the output of the modules.

Floating Solar Power Plants

April 30, 2019

As we all would agree, solar power, especially the installation of floating solar power plants have gained significant popularity and acceptance in the energy sector. PV installations have proved to be cost efficient and carbon-light way of producing every from the solar radiation. Excluding the high initial investment, another big challenge for making PV installations more abundant is the need for land. While in large countries like Australia, the USA, or India availability of land is not a constraint, in many small countries, or islands like Japan, Malaysia, etc. availability of land is a major constraint.

Weather conditions, including the temperature in which the solar panels are operating, have a considerable effect on the performance of the solar panels. It might sound counter-intuitive to many of us, but low temperature actually boosts the performance of the solar panels. Solar panels, like any other electronic device, are more productive at low temperatures.
