IF you provide information on the sort of solar panels you have in mind, I'm sure someone here can guide you as to a system with batteries, and use it to power an inverter. Solar panels (I'm assuming you mean photvoltaic - ones that produce electricity) do not always have to be expensive, although many commerical companies manufacturing them are only concerned with area efficiency, and so, do not produce the cheaper ones. So us westerners only have the high quality (read: expensive) types available to us.
