 PWM are cheap enough that it is common to start with PWM and upgrade to MPPT later only if necessary. ​ After one upgrades from the PWM unit it can be kept as a spare/​emergency part.  PWM are cheap enough that it is common to start with PWM and upgrade to MPPT later only if necessary. ​ After one upgrades from the PWM unit it can be kept as a spare/​emergency part.
