For PV source and charge controller sizing and selection it is necessary to have a minimum ambient temperature value in °C that these components are likely to be exposed to. It is not necessary to use the lowest temperature ever recorded - the lowest value during a multi-year period will suffice. The lowest recorded temperature can be used, but it is unlikely that the PV modules would see this temperature and be exposed to sunlight.
