    These panels are not certified, so would be illegal for grid-tie installation. They will deliver the numbers published, but you incur additional expenses (MPPT controller) in order to direct their full output power. With a Vmp of 23.7, these 24Volt panels are unable to charge a 24V battery bank. The more expensive type of MPPT controller must be used to either down-convert, or regulate a series of panels to the charging voltage you need.
