Nov 19, 2007 -- /prbuzz/ --Sunnyvale, California – Nov. 19, 2007 – Wattminder, an energy & utilities monitoring service provider, launches today a free, public service Real-Time PV Performance bench mark website. It offers a sorely needed performance reference checkpoint for all solar electric system owners, available globally at www.pvperformance.com.
Any solar system owner and operators can now obtain mathematical model derived performance bench marks on line, and stop wondering about how their system is performing.
“After assessing or observing hundreds of solar installations, I concluded a large proportion of PV installations is not performing properly, and is un-noticed by their owners and operators, due to a lack of monitoring system. I decided to do something about it.” continued Steve Yang, P.E., president of wattminder-Yang Associates, “This condition had been reported in CEC/PUC and National Renewable Energy Laboratories (NREL) sponsored studies.”
A visitor to the website, also reachable by www.pvmonitor.net, or www.pvcheckup.com, simply enters a brief set of values for 'vital statistics' of a solar system. The free performance predictor will output a look-up table for a number of environmental conditions, that this visitor's PV system should be producing at that instance—given the Sun's position and the solar array's location and attitude, as well as temperature of the solar panel(usually 10 to 20 degrees higher than the ambient). The values provided serves as a checkpoint for a PV system owner who does not have a monitoring system, or if monitoring system does not indicate how well his/her system is performing. He/She may then manually check on his system's power meter reading, or from display on the inverter readout. If the numbers match, or co-relate well with each other, under somewhat different operating conditions, it would indicate his PV system is performing reasonably well. “We hope, by providing this free bench mark service, under-performing systems can be identified, and brought to the attention of its install contractor, who should then correct any performance issue, thus restoring an under-performing system to its full capacity.” asserted by Yang.
About Wattminder – Wattminder, Inc, www.wattminder.com, is a Silicon Valley startup enterprise with a mission to leverage the convergence of internet, wireless communications, software technologies, and artificial intelligence methodologies to bring positive and meaningful impacts to the global warming crisis and get real-time, visibility over natural resources usage and generation.
