SEVEN Soiling Sensors for an Accurate Soiling Monitoring in PV Plants
Measure, Monitor, and Maximize PV Performance with SEVEN Soiling Sensors
Soiling is one of the most underestimated threats to solar plant performance, with dust, sand, or pollen gradually forming a layer that blocks sunlight and reduces energy generation — sometimes by as much as 20% in dusty or arid regions. SEVEN’s advanced soiling sensors help operators take control of this silent efficiency killer by providing accurate, real-time data on how dirty the panels are getting. By comparing irradiance measurements from a clean reference cell with a soiled cell, these sensors calculate the soiling ratio and give operators a clear picture of energy losses due to dirt. Armed with this information, maintenance teams can schedule cleanings exactly when needed, saving water and labor while maximizing energy output. SEVEN offers a complete lineup of soiling sensors to suit different needs: manual models for cost-effective, hands-on monitoring; automatic sensors for continuous, maintenance-free tracking ideal for large or remote PV plants; and portable units perfect for inspections or temporary setups across multiple sites. By integrating SEVEN’s soiling sensors into your monitoring strategy, you can optimize performance, reduce operating costs, prevent unexpected output drops, and protect the long-term health of your solar investment — no matter where your installation is located.
