A decent solar-based system can cost about $11,500 to build and install. So, while this solar option is economically competitive with a generator without the negative environmental impact, and far cheaper than installing an extension line from a utility company for some, the cost is still expensive, and for those with easy access to traditional power, the cost does not seem justified, despite the environmental impact.
However, other drawbacks that limit the popularity of solar powered homes is the fact that most solar-based power systems must be custom-designed to fit the specific requirements of each site. This only increases the cost widening the gap of price with the solar-based systems ending up a long way off from being economically competitive with power from a utility company.
New technology is being developed daily, and with new government regulations on thermal power, etc. the popularity of solar powered homes is beginning to rise. Also, not having to count on a company to provide your power is attractive. The self reliance, self sufficient aspect is great, however, often the cost outweighs this attractive feature. Many have found that using a partially solar powered home, and partially utility company powered is a viable alternative, and the middle road. This alternative leaves room for upgrading later, or expanding your solar powered system as the need arises, or as funds become available.

One thing to realize is that solar powered homes are not just for sunny areas like Southern California, in fact, some solar powered systems can still generate power under 7 or 8 inches of snow. So, do not dismiss the idea of solar powered energy systems because of your climate. Solar energy is a tricky thing, so speak with a professional to determine what the costs and abilities are for your area.
