WASHINGTON, DC -
In a move condemned by many solar companies in Arizona, the state's largest utility, APS, has announced that it will begin installing rooftop solar on customers' homes. After learning of the news, Ken Johnson, vice president of communications for the Solar Energy Industries Association (SEIA), issued the following statement:
"After attacking rooftop solar companies in Arizona relentlessly for more than a year, this latest tactic by APS has a ‘Trojan Horse' smell to it. Our member companies welcome fair and equal competition, but this move would stack the deck in favor of a company which can rate base solar with a guaranteed rate of return. How is that fair? The Arizona Corporation Commission (ACC) needs to think this through very carefully."
In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
