Novice with a project
I'm very much a novice, but I'm here to learn and grow. I am designing a system using solar cells and lights. I would store the power in a battery off the grid and it would be outdoors at all times. I live in Wisconsin, so the shortest day of the year yields likely 9 hours of light (best to measure from the worst scenario). I'm looking at lights rated at 50W. Can I assume that is a watt used over an hour? On the shortest day of the year, there would be 15 hours of darkness. With a 50 watt bulb, that would be (15x50) 750 watts used over the course of the night (then scaled linearly for as many lights as I'd want). Correct? A solar panel would need to generate a minimum of 750 watts during the day to power this since no lights run during the 9 hours for this example (theoretically). This does not account for the decreased power generated during cloudy days. The max load I'm estimating for my project is about 2300 watts in a 24 hour period. Any thoughts on sizing batteries? I'm looking at 120v batteries due to the lighting requiring it. Another concern I have is insulating the battery against very cold and very warm temperatures. Any thoughts there? Thanks for any help you guys give.
