Cost-effective tools to optimize photovoltaic systems
Beeservices India offers cost-effective tools, including a PV monitoring package, to monitor solar energy resources, optimize panel placement for maximum efficiency, monitor photovoltaic system performance, and determine site location.
PV-100 PV Monitoring Package
Beeservices PV monitoring package is designed to work with an SMA cluster controller and includes a silicon-cell pyranometer, Class A PRT back-of-panel temperature sensor, fan-aspirated radiation shield, and Class A PRT air temperature sensor.

Silicon-cell Pyranometers
Beeservices silicon-cell pyranometers feature a monocrystalline silicon-cell detector that has the same spectral response as a PV module. The sensors quantify shortwave radiation being harnessed as electricity.
Same Characteristics as a PV Module
Beeservices silicon-cell pyranometers feature a monocrystalline silicon-cell detector that has the same spectral response as a PV module.
Rugged, Self-cleaning Head
Patented domed shaped sensor head (diffuser and body) facilitate runoff of dew and rain to keep the diffuser clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodize aluminum body and electronics are fully potted.
Output Options
Multiple analog output options are available including: 4 to 20 mA, 0 to 2.5 V, 0 to 5.0 V, and 0 to 350 mV ranges. The silicon-cell pyranometer is also available attached to a hand-held meter with digital readout, and as a digital ‘smart’ sensor that uses USB communication and custom software to interface directly to a computer.
Thermopile Pyranometers
Beeservices thermopile pyranometers are cost-effect and feature a blackbody thermopile detector that provides a broader and more uniform spectral response for better performance in all atmospheric conditions, particularly under cloudy conditions.
Fan-aspirated Radiation Shield
Did you know that traditional multi-plate radiation shields cause ambient air temperature measurement errors up to 10 C in high solar, low wind conditions? With many performance monitoring standards calling for a measurement uncertainty of less than 1 C, this is a large and frequently overlooked problem. The TS-100 is the solution. The unique shape and ultra-low-power fan ensure an uncertainty of only 0.2 C in all conditions.
