Sunnyvale, California Nov. 25, 2007 Wattminder, an energy &utilities monitoring service provider, launches today a free, public serviceReal-Time PV Performance bench mark website. It offers a sorely needed performancereference checkpoint for all solar electric system owners, available globally atwww.pvperformance.com. Any solar system owner and operators can now obtain mathematical model derivedperformance bench marks on line, and stop wondering about how their system isperforming. After assessing or observing hundreds of solar installations, I concluded a largeproportion of PV installations is not performing properly, and is un-noticed bytheir owners and operators, due to a lack of monitoring system. I decided to dosomething about it. continued Steve Yang, P.E., president of wattminder-YangAssociates, This condition had been reported in CEC/PUC and National RenewableEnergy Laboratories (NREL) sponsored studies. A visitor to the website, www.wattminder.com, or www.pvperformance.com, simplyenters a brief set of values for 'vital statistics' of a solar system. The freeperformance predictor will output a look-up table for a number of environmentalconditions, that this visitor's PV system should be producing at that instance giventhe Sun's position and the solar array's location and attitude. The values providedserves 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 displayon 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 isperforming reasonably well. We hope, by providing this free bench mark service,under-performing systems can be identified, and brought to the attention of itsinstall contractor, who would then correct any performance issue, thus restoring anunder-performing system to its full capacity. About Wattminder's Wattminder's, Inc, www.wattminder.com, is a Silicon Valleystartup company with a mission to leverage the convergence of internet, wirelesscommunications, software technologies, and artificial intelligence methodologies tobring positive and meaningful impacts to the global warming crisis and getreal-time, visibility over energy usage and generation.
