Hi guys
Looking for some advice for a school project. We're looking to see if we can design a solar system that could power sport field floodlights that have a draw of 19.4KwH.
These floodlights would rarely be used during the summer, but during the winter could be three times a week for 3 hours at a time.
During the winter we get around 6.5 hours of daylight.
What size off grid solar system would we need to ensure we had enough power to run these floodlights, including batteries?
The challenge we have is all calculators we have found say to find out the power requirements of something and then multiply it by the number of hours used per day and then by days in the week, but these floodlights would be the only draw on this power supply and are only used for 3 hours at a time, so if used Saturday then potentially no more power needed until Tuesday evening, so for 3 full days the batteries could recharge.
The other information I have about the floodlights is: 16 floodlights with 1.2kW per fixture and around 3.3Amps assuming 3phase.
Any advice, help?
