Do you want to know whether your PV system is working as expected? A very useful way to assess the overall quality of your system is the performance ratio. Every system owner should know about it since the performance ratio gives you a much needed reality check. The performance ratio, abbreviated as PR, specifies the difference between what you paid for and what you actually get. PV systems are sold in terms of kilowatt peak system size, but their output is always reduced by an additional factor - and this factor is just the performance ratio. Often generic values are used for the performance ratio neglecting the fact that performance varies widely from system to system. An actual system can have a PR as low as 50% or as high as 90%. Our estimate gives you the specific number for your PV system. Just follow these easy steps and get your Yield Check.
