Solar power generation solar radiation monitor

basic information

In measuring solar power generation, conventional pyranometers show an error of about 2%. One reason for this is that, traditionally, there have been no instruments other than meteorological pyranometers to measure solar radiation, and there has been a lack of rigorous measurement in evaluating power generation. Even a slight error can accumulate over the years, resulting in significant losses. The solar power radiation monitor addresses this issue and supports high-precision business operations.

Detailed information

• 

  Elimination of measurement errors of about 2% that occurred with conventional methods In measuring solar power generation, conventional solar radiation meters have shown an error of approximately 2%. This is attributed to the fact that, until now, there were no instruments other than meteorological solar radiation meters to measure solar radiation, and that rigorous measurements for evaluating power generation had not been conducted. Even a slight error can lead to significant losses when compounded over years of power generation. The solar radiation monitor for photovoltaic systems addresses this issue and supports high-precision business operations.

• 

  High response speed and excellent spectral sensitivity characteristics. Conventional pyranometers, even those with high precision, have slow response times, leading to significant errors in evaluating solar power generation. Solar power monitoring devices have the same output characteristics as solar panels, allowing for high-speed response and accurate measurement of generated power. The response characteristics of conventional pyranometers have flat spectral sensitivity across all wavelengths, resulting in output even in wavelength ranges where solar modules do not generate power. However, due to having the same spectral sensitivity characteristics as solar panels, accurate power generation can be captured.

• 

  No need for installation and management of a thermometer. The solar power radiation monitor is also equipped with a temperature sensor. With this single device, solar radiation and the temperature directly beneath the panel can be measured simultaneously in the same location, allowing for more accurate weather data and significantly improving the accuracy of power generation data aggregation. Additionally, there is no need for the costs and effort associated with separately installing and managing a radiation meter and thermometer as in the past.
