This represents the change in voltage output for degrees difference above or below the standard test conditions (25° C, 1000w/m2) The hotter it is the efficiency drops leading to lower voltage Colder is more efficient so higher voltage. A cold clear day can be the highest output.

With 8 kWh of stored energy and nearly 1,000W of real-world power in direct sun (and often 600-800W in less-than-ideal conditions), this is a seriously powerful system for just charging up all my EVs. This could power a tiny home or other small off-grid setup like a hunting cabin.
