you need to look at the panels and the relative amount of direct sunlight they get then you find the effective rate.. they may even just break it down like with full sun light this unit will produce X amount of watts.. from there it goes threw a computer and then into a battery bank. you need to find the amount of watts you want to run.. ie find out exactly what you need for the fans and pumps plus the 1000w. also you need to find your consumption rates. are you going from 12/12 or 18/6 or 24/0 .. once you find all these things out look online for solar companies and do your own independent research on it. There will be quite the investment right off the bat. when people use them on their houses they get a break and actually can give electricity back to the power company when not in use. because you are off the grid this would not be the case. if your going to be lazy you can just post your consumption rates here and somone may help you out.. but if you are lazy enough to not look your own i highly doubt you will ever install them
