Patent ID: 8190385

Claim:
A system for testing a first solar panel, the system comprising: an apparatus adapted to be electrically coupled to the first solar panel and a second solar panel, the apparatus comprising: a processor; a memory comprising a plurality of instructions stored therein and executable by the processor, the plurality of instructions comprising instructions for calculating a ratio of respective operating parameters of the first and second solar panels; an output device configured to display the ratio of the respective operating parameters of the first and second solar panels; a first load electrically coupled to the processor and adapted to be electrically coupled to the first solar panel; and a second load electrically coupled to the processor and adapted to be electrically coupled to the second solar panel; and wherein the instructions for calculating the ratio of the respective operating parameters of the first and second solar panels comprise: instructions for detecting an operating parameter of the first load; instructions for detecting an operating parameter of the second load; and instructions for calculating a ratio of the respective operating parameters of the first and second loads, wherein the ratio of the respective operating parameters of the first and second loads corresponds to the ratio of the respective operating parameters of the first and second solar panels.
