If you have no source of electricity, no availability of fuel for a generator, or are very rich and don't mind spending a lot of money with no return on your investment, it's an option. Wind and water power are much cheaper, but you need to have a source of almost constant wind or water. Solar electricity is expensive not only because it requires very expensive equipment to generate the electricity, it requires a large investment in batteries to store it. The batteries must be protected from heat and cold, have relatively short lives, etc. You also need the Sun which is not easy to get. The farther north (or south) of the equator you are, the shorter the days are in the winter, which means less charging time and longer battery drain. You also loose power on cloudy days, solar heaters don't work well when it rains, and so on. The collectors need to be cleaned often, a small amount of dust reduces efficency dramaticaly. The Sun travels across the sky from east to west at the equator. This means that fixed arrays only get exposed for a relatively short time. The farther away from the equator, the path becomes south-east to south-west (or if you are below the equator, north-east to north-west), but unless you are very near a pole, it's still a wide transit. Self positioning solar cell arrays are available, but they are far more expensive, far more complex and far more prone to damage. Solar heating is far cheaper and easier than electricity.
