There is little doubt, however, that in the long run the average consumer would save more money by purchasing solar-powered products. Appliances powered by solar energy are likely to reduce utility bills overall, and yet consumers, for the most part, are still not showing any signs of acceptance. The fact that it can currently cost thousands of dollars to install any solar-powered product is presumably one of the biggest deterrents. As of now, statistics show that on average solar energy would cost $10-12 per watt to power a household. These costs can often be reduced, however, through state incentives.
Another factor impeding the widespread use of solar power is the simple inconsistency of the weather in many areas. Weather changes can have a direct impact on any solar-energy-based system. Imagine one of those grey days when the sun is not out — a solar panel is rendered useless on such days, something that would not be greatly appreciated by a consumer. And if you happen to be in a region where sunny days are a luxury, then using solar energy would obviously not be a wise move.
Clearly, before companies can start marketing solar-powered products, they need to spread a general awareness about the nitty-gritty involved in the typical installation process and provide a clear understanding of how solar power works and why it should rightly be considered a more economical source of energy.
In other words, companies still have a long way to go before they can take a full plunge into solar energy and convince consumers to take the plunge with them.
