Checking the peak sun hours for Florida here, you can see that annual average peak sun hours in Florida come to 6.16 h/day. That means that a 6 kW solar system in Florida can generate (on average) 27.72 kWh per day, 831.60 kWh …
In 2023, solar power generated 5.5% (1,631 TWh) of global electricity and over 1% of primary energy, adding twice as much new electricity as coal. [4][5] Along with onshore wind power, utility-scale solar is the source with the cheapest levelised cost of electricity for new installations in most countries.
