Want to know what your PV system should be producing?

To address the problem of prevalent, un-detected, under-performance in many solar installations. We launched 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.

A visitor to the website, www.wattminder.com, or www.pvperformance.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 instance­g iven the Sun's position and the solar array's location and attitude. 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.
