All-out Irradiation Sensor
It is a breakthrough sensing device that measures Global Normal, Direct Normal and Diffuse Horizontal solar Irradiance without sun trackers or other moving parts.
Irradiation monitoring made simple, accurate, affordable!
- Small, rugged, portable and ligthweigth
- Extremely easy to install and to maintain
- Polar alignment and tilt-plane independent (only CaptPro version)
- Usable under any weather conditions
- Natively designed to be configured in wireless distributed sensing networks delivering highly accurate irradiation assessment and no need for routine calibration
Three versions
Its game-changing design and proprietary algorithm summarize in a single self-standing device the output of pyranometers and pyrheliometers, while eliminating the need for extra equipment, such as solar trackers.
In its more advanced versions, it also calculates the Optimal Inclination of the tracked PV panel, the Maximum Irradiation Angle based on the current measurements of direct and diffuse irradiance. It also delivers measurements of the Global Horizontal, the Direct Beam Horizontal, the Global Tilted Irradiance, spectral-weighted on the PV panel technology too, the Ground Reflected Irradiance, and all solar irradiation components divided in four different spectral bands (IR, Red Green, Blue).
Cut costs, grow profits
By dramatically boosting the fine-grained localization of system failures, inefficiencies and production drops with unmatched, pin-point detail, All-out Irradiation Sensor allows to maximize energy production, reduce O&M costs, and to increase profitability for investors, owners, and managers of PV plants.
At a cost sensibly lower than a single monitoring station featuring pyranometers, pyrheliometers and sun trackers, and with dramatically lower maintenance cost, a wireless network of All-out Irradiation Sensor nodes provides +300% more accurate information about plant performance, 10x more precise localization of faults, and the detection of production drops of the order of 1%, thus enabling an increase of up to +5% in energy yield.
