Solar PV arrays are relatively simple and straightforward systems – there are next-to-zero moving parts and they operate on a daily basis without any human assistance.

Additionally, because most solar systems are installed in parallel with the grid, disturbances on the wider network can also cause problems with your solar array.
With this in mind, unless you have the time/resource
