This looks like about 300W load, similar to a small cottage. I'm going to assume the fan runs almost all day, and laptops, perhaps 4 hours, and light, 8 hours. We ended up with about a requirement of 3-4 kWh / day. That is an array of 800 W in a place like southern California, Nevada, or Arizona, taking into account losses including battery and inverter. $ 4-5k, assuming you do the work yourself. And it's a pain to maintain batteries. It is hard to make system of this size pay for itself if the electrical grid is already available. But it could be a fun thing to do.
