Being a photovoltaic enthusiast, I am making an effort to address the problem of prevalent, unknown, or undetected under-performance of many solar generation systems.

It is largely unknown because most solar systems do not come with monitoring system/service. With this free service, we hope to make a difference in the fight against global warming.

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, Welcome to the Solar Performance Website, 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 instance, ­given 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 track 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 would then correct any performance issue, thus restoring an under-performing system to its full capacity.

We are committed to continually refining this service, with our own resources, or any outside contribution.

Thanks for visiting and critiquing, and please give it a good try in its initial rendition. MORE POWER TO YOU!
