Skip to the content Solar Radiation Sensors are used to measure the power of the light from the sun. We offer four primary types of solar radiation sensors; PAR Sensors, Pyranometers, Quantum sensors and general purpose Solar Radiation sensors.
Solar radiation sensors measure solar energy and provide outputs corresponding to the level of radiation being monitored. Combined with a display or control device, the user can receive an alert when solar intensity reaches a predetermined threshold level. This can be useful for controlling solar powered equipment and systems such as solar lighting and solar panels.
Solar Radiation Sensors are commonly used in climatology, meteorology, building physics and solar energy studies. They are also used in weather stations and are often installed in a horizontal manner near solar panels. Additionally, solar panel sensors play a crucial role in monitoring the performance of solar energy systems, ensuring efficiency and optimal energy production.
Experts in the fields of meteorology, building physics, climatology, and solar energy generally rely on state-of-the-art solar sensors the most. However, these sensors also aid weather stations.
Solar radiation sensors detect sunlight and measure its intensity using either:
When light strikes the sensor, it generates an electrical signal proportional to the sunlight intensity. This signal can be displayed in real-time, logged for analysis, or used to control devices such as automated blinds, irrigation systems, or solar tracking systems.
Comparison of Solar Sensor Types
| Sensor Type | Measurement Range | Best For | Advantages | Limitations |
| PAR Sensor | 400–700 nm | Agriculture, plant studies | Measures plant-useful light | Not suitable for full-spectrum solar studies |
| Pyranometer | 285–3000 nm | Meteorology, solar energy | Measures total solar irradiance | Higher cost |
| Quantum Sensor | 400–700 nm | Scientific research | High precision, stable readings | Limited spectral range |
| General Purpose Solar Radiation Sensor | Varies | General monitoring | Versatile, cost-effective | Less specialized |

If you want to track performance, detect issues, and maximize output, a solar sensor is highly recommended.
Our models are designed for professional and research-grade accuracy, with tolerances typically within ±5%
With proper maintenance, Comptus solar sensors can operate reliably for many years in outdoor environments.
Solar radiation is typically measured in watts per square meter (W/m²) or micromoles per square meter per second (µmol·m⁻²·s⁻¹) for PAR measurements.
Calibration frequency depends on usage and environmental conditions, but most professional applications recommend recalibration every 12–24 months to maintain accuracy.
Yes. Comptus solar radiation sensors are compatible with most data loggers, controllers, and automated weather station systems.
Most models are passive and generate an electrical signal from sunlight. Some advanced models with digital outputs may require a small external power supply.
Cloud cover, dust, snow, and shading can lower readings. However, high-quality sensors can accurately measure both direct and diffuse sunlight.
While designed for outdoor sunlight measurement, certain applications (e.g., indoor plant lighting studies) may benefit from PAR or quantum sensors indoors.
Yes, all our solar radiation sensors are built for outdoor use and have weather-resistant housings to protect against rain, snow, and humidity.
Absolutely. By comparing solar irradiance readings with panel output, you can identify efficiency losses due to dirt, degradation, or shading.
Regular cleaning of the optical surface, occasional calibration checks, and inspection for cable or mount damage are typically sufficient.
