All-out Irradiation Sensor
It is a breakthrough device that measures all components of the solar radiation 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 different versions
- CaptPro measures global normal, direct normal, and diffuse solar irradiation.
- CaptPro+ measures global normal and horizontal, direct normal and horizontal, and diffuse solar irradiation. It also provides GPS coordinates, the optimal PV panel inclination and the ETPR (Effective Tracked Panel Radiation) output data spectral-weighted on the PV modules technology and therefore it furnishes in real time the optimal production curve of the PV plant for PV modules.
- The most advanced version, CaptPro++, measures, in addition to all the quantities of CaptPro+, also the ground reflected solar irradiation and therefore it provides in real time the optimal production curve of the PV plant also for bifacial PV modules. It also furnishes the measurements of the all solar irradiation components divided in four different spectral bands (IR, green, red, 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.
