What sort of problems do you hope to detect?
It may not be as easy as you think - even with the correct equipment and program.
Also, solar panels are pretty reliable. I would not be inclined to spend much time or money checking for faults. Bird poo or autumn leaves might be the biggest problems.
Measure the ambient light level and the output of the solar panel (in watts). Record those measurements for a while (week, month, year). Develop a table of the expected range of power (watts) output for each ambient light level. Then, if the power output goes out of range, signal an error.
