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 as low temperatures typically occur before sunrise.
