I think you should first figure out how much power you will need for any given task. For lighting I would go with low voltage lights like LEDs, they are extremely energy efficient. I would also try to stay away from devices that require 110-volts AC, an inverter takes a lot of power to do it’s job. Also look into reducing your electrical needs before you build a solar / battery pack. Every watt you can save, is a watt you don’t have to generate. Solar panels are expensive and produce little for the money you put into them. And they take all day to do their job.
