Until now, when measuring solar radiation and temperature with solar power generation equipment, signals were sent through converters while considering sensor noise. The PV scanner uses a noise-resistant A/D converter, allowing for direct signal input. This enables the simplification of the solar power generation system and cost reduction. To launch the measurement program, you can easily start measuring by simply clicking the measurement start icon.

The sensing part uses a special film with excellent temperature characteristics and mechanical properties as a substrate, and is equipped with a thermopile that has multiple contacts to detect the temperature difference between the center of the sensing part and the diameter direction. The outer circumference of the sensing part is bonded to a metal holder with an appropriate thermal capacity, which responds to changes in solar radiation intensity, resulting in a temperature difference between the center of the sensing part and the diameter direction. The solar radiation amount is determined by measuring the direct current voltage proportional to that temperature difference. The sensing part has no wavelength dependence and is coated with a special black paint that has good absorption properties.

The solar tracking system has two operating modes: sun sensor mode and calculation mode, which switch automatically. In sun sensor mode, a sun sensor equipped with a four-segment silicon photodiode captures the position of the sun in real-time with high accuracy. In calculation mode, when the output from the sun sensor cannot be obtained due to overcast conditions, automatic tracking is performed based on solar trajectory calculations by the CPU. The threshold for switching based on solar radiation intensity is calculated based on solar altitude (air mass) and latitude, ensuring appropriate switching at all times. The difference between the solar tracking position in calculation mode and the solar tracking position in sun sensor mode is learned in real-time. If the sun sensor captures the sun within ±15 degrees of the calculated position, the tracking learning function is activated, allowing for more precise solar tracking.

The output from the diode array is converted by the built-in CPU and then output via RS-232C. The measurement results are displayed on a PC. This device measures in a short time (measurement time for one scan: 5ms to 5s), and there are no mechanical movements. Additionally, the unit of measurement can be set not only to radiation (W/m2) but also to photon flux (μmol/m2/s).

This device measures the current-voltage characteristics (I-V curve), which is important for evaluating the performance of solar cells, and is ideal for assessing the performance of solar power systems ranging from large solar cell modules over 100W to 10kW. Compared to previous I-V curve tracers, it is compact and lightweight (A4 size, 2.8kg), and does not require a computer for measurements; you can simply operate the built-in keyboard, and the LCD display shows the I-V curve, Voc, Isc, Pm, etc., allowing for immediate performance evaluation, making it extremely convenient for field measurements. The measured data can be stored in the internal memory for up to 70 readings, and you can freely read or delete them, so you can use it with confidence even when a lot of data is required. The solar cell input terminals adopt a four-terminal input method, ensuring high measurement accuracy while also implementing sufficient safety measures for human beings. By using the optional Windows 98-compatible measurement and analysis software, it can also support text saving, standard state conversion, and automatic continuous measurements.

This device measures the total solar radiation incident from the sky onto a horizontal surface and is a pyranometer that corresponds to First Class as defined by ISO 9060. The sensing element has no wavelength dependency and is coated with a special black paint that has good absorption properties. Additionally, by adopting a double glass dome structure, it is designed to be less affected by variable factors other than solar radiation (such as wind and temperature changes). Similar to the MS-802, the adoption of a new thermopile has significantly improved the response speed and temperature characteristics compared to the old model (MS-401). There is also a version with forced convection for protection against frost and snow during winter (MS-402F).

This device measures the total solar radiation entering from the sky and is a high-precision all-weather solarimeter that complies with the Secondary Standard as defined by ISO 9060. The sensing element uses a thermopile with uniform spectral sensitivity across the entire wavelength range of solar radiation and stable performance. The MS-802 model features a new thermopile that has approximately doubled the response speed compared to the previous model (MS-801), and the temperature characteristics have been improved by about 40% through changes in the thermal structure. Additionally, the sensing surface is protected from variations in factors other than solar radiation (such as wind) by being covered with a double dome. The MS-802F has a fan installed at the bottom of the sensing surface holder, which blows air to the outside of the glass dome, preventing the accumulation of frost, snow, dust, and other debris.

At Eihon Seiki, as a pioneer with over 10 years of experience in solar cell measurement, we have successfully developed an I-V curve tracer capable of measuring silicon-based solar cells to next-generation solar cells. This next-generation I-V curve tracer, "MP-160," is a solar cell evaluation device with a wide measurement range and high resolution that can meet all requirements, from ultra-low output cells to high-output modules, based on a newly designed electronic load method. In outdoor measurements, the automatic measurement mode allows for long-term continuous data acquisition, and by connecting an optional module scanner, simultaneous evaluation of up to 48 modules is possible, making it suitable for exposure degradation tests. In indoor measurements, high-speed simultaneous sampling of voltage, current, and light intensity (such as reference cells) is enabled, and the fluctuation correction function of the lamp light source allows for more precise measurements. Additionally, it supports steady-state and flash light solar simulators, and by combining it with a cooling constant temperature plate for cell temperature control and an automatic transport device, it can be introduced from research facilities to the latest production lines.
