Example of SunMath PV Comparison

PV Comparison showed me my solar installation was underperforming by 30%. A quick review by the installer showed they accidentally installed the wrong size inverter - a costly mistake I couldn't have known about without your service. Thanks!

SunMath (, a leading developer of innovative, web-based tools for the solar industry has recently launched its newest software tool, PV Comparison. This free tool uses crowd-sourced data to help solar installation owners diagnose solar system inefficiencies.    

This free tool allows solar installation owners to determine if their installation is performing optimally by comparing the electricity production of their system to other nearby systems. In order to make the comparisons apples to apples, SunMath uses proprietary algorithms to adjust for differences in system specifications, including system size, orientation, tilt and age.

Currently, homeowners and businesses interested in optimizing their solar installations either have to (1) pay for a solar professional to do an electrical diagnostic test, or (2) compare their electric production to long-term weather datasets. Paying a solar professional to come out regularly is costly and comparing real-time production to historically-derived production can result in misleading results due to up to 50% variations in weather patterns. SunMath’s tool is completely free, real-time, and uses comparable systems as close as a mile away, meaning variations in weather do not affect the validity of results.

Increased Accountability
SunMath believes the PV Comparison tool introduces additional accountability for solar installations engaged in the solar installation process. This accountability should lead to higher quality installations and quicker diagnosis of system issues, even if those issues result in only diminished power production.
