Recent data from the National Renewable Energy Laboratory (NREL) shows solar arrays can reach temperatures up to 65°C (149°F) – that's hotter than your morning coffee and roughly equivalent to frying an egg on your rooftop!.

🔹 What It Means: This is the highest voltage (in volts, V) the panel can generate when no current is flowing (i., when it's not connected to anything).

This, along with the use of new types of lightweight materials, including aluminum alloys, composite materials, and thin metal foils, in solar panel construction, allowed engineers to equip spacecraft with even larger solar panels.
