About This Product
■Summary
The SPN1 pyranometer uses an array of seven miniature thermopile sensors and a shading pattern to measure direct and scattered incoming solar radiation.
SPN1 can monitor the efficiency of solar power generation equipment. It is particularly useful when choosing a location for concentrator photovoltaic (CPV) installations, as it measures direct and scattered solar radiation without the need for complex adjustments, shading rings, or other moving parts.
■Features
・Precision frosted glass dome
・Broadband thermopile sensor
・Ideal spectral response and cosine response
・Standard output sensitivity
・Direct/scattered solar radiation
-No moving parts, no adjustment required
・Direct solar radiation intensity (DNI) calculation
・Sunshine condition
■Measurable units
・Total solar radiation
・Scattered solar radiation
Purpose
■Solar energy
Reliable solar radiation data is the lifeblood of solar energy equipment development, installation, and observation. The SPN1's high quality, versatility and ease of use are reflected in its superior functionality and value for money in these measurements. It is particularly suited for site selection, testing and evaluation of concentrator photovoltaic (CPV) installations, as well as thermal systems that collect energy from direct solar radiation.
■Weather observation
SPN1 obtains the solar radiation status using an advanced algorithm that matches values close to the WMO standard threshold for direct solar radiation (120W.m^-2). Easy-to-understand all-sky/scattered solar radiation analog output (1mV=1W.m^-2) and solar radiation conditions can be easily recorded as part of long-term climate/environmental studies, reducing maintenance control compared to traditional instruments You can significantly reduce costs.
■Advantages
SPN1's unique combination of features makes it an excellent choice for weather observation and solar energy observation.
■Innovative design
The patented design consists of 7 mini thermopile sensors and a unique blackout pattern.
■No moving parts
SPN1 requires no adjustment after installation. Unlike shadow band or rotating ring pyranometers, the SPN1 has no moving parts.
■Multiple outputs
SPN1 provides all-sky/scattered solar radiation analog output and solar radiation status. From your saved data, you can calculate both Direct Insolation Intensity (DNI) and Sunshine Duration.
