Requirements for Solar Radiation Measurement Systems

Planning for solar projects is becoming increasingly dependent on the radiation data available before the installations are performed. Any minor inaccuracy of the data might impact the calculations regarding the expected energy generation and affect assumptions about the system size and future reviews of its performance. As a result, solar radiation measurement systems become an important part of planning for development teams, rather than just monitoring equipment.

First of all, the role of such systems starts with the initial analysis of the project. Solar irradiance measurement gives an insight into the amount of the resource at a certain location and allows the developers to estimate the expected generation at the given site. If the information is limited or inconsistent, calculations of financial models and engineering decisions might be affected.

At the same time, measurement requirements depend on the conditions at the given location. Assessment of a large-scale installation will need a detailed long-term study of radiation at the location. Smaller projects might be interested only in local radiation conditions. Seasonal variations, atmospheric and weather conditions can impact the amount of sunlight that reaches the panels.

Therefore, the ability of measurement systems to provide the data that will reflect the changing condition becomes very important. Instruments that measure solar radiation should be capable of reflecting the changes that happen due to the movement of clouds, atmospheric conditions, and daily fluctuations.

Moreover, the need for accurate measurement is crucial for further operations as well. Solar power plant operators will need to compare the actual generation with the expected output. In case the output falls below the projections, measurement of the solar conditions will allow finding the reasons for such a discrepancy.

For technical teams, this step requires the ability to refer to dependable data. Without the knowledge of the available sunlight, a performance review will become difficult since there will be no baseline for such a review.

Market demand for solar radiation measurement equipment is based on the need for easy deployment of the device. Field teams are working at locations that have limited access. Therefore, it is important for the instrument to provide consistent performance with limited maintenance and data collection requirements.

As solar adoption increases in a variety of conditions, measurement systems become a part of the planning process, rather than just the monitoring devices. Their role is in reducing the uncertainty that exists before the decision-making and increasing the visibility after the systems start functioning.

The key requirement for buyers is not just the capability of the measurement system to collect information about sunlight. Instead, it is related to the ability of collected data to make accurate decisions at all stages of the project lifecycle.
