I am terrible at math and cannot figure out what size of panel I would need. It's driving me nuts. I would like to build a grow room for vegetables in my home and use it during the winter (I'm in Canada) I would love it if I could get the lights to run off solar. I'm estimating a 600w light running for 16h/day. What size or wattage of panel would I need? I don't know how to do all these conversions. I've tried Google but keep getting confused LOL!
