Description
Product Overview
SEVEN Snow Sensor is designed to measure the loss in energy production caused by snowfall on photovoltaic modules. Suitable for both ground-mounted and rooftop PV projects, the sensor notifies operators of production losses due to snow accumulation. A snow ratio reading of 10% corresponds to an estimated 10% energy loss for the facility.
How it works
Snow Ratio = Energy Loss. The SEVEN Snow Sensor calculates the snow ratio for the PV plant by comparing irradiance data from two reference cells: one affected by snow and one snow-free. This comparison yields a direct indicator of production loss caused by snow coverage.
Tracker integration
The SEVEN Snow Sensor provides a dedicated solution for PV installations with solar tracker systems. By analyzing irradiance from the snow-covered and snow-free reference cells, the sensor computes the snow ratio and communicates this value to the tracker control center to adjust module positions according to snow accumulation, avoiding unnecessary tracker movements.
