In 2008, solar panels were a relatively new innovation usually reserved for use in large buildings and businesses with a large amount of scientific funding or excess revenue. Although some homeowners had installed them, it was primarily a luxury. They are now regarded as one of the most environmentally and economically beneficial home improvements.
That changed in 2009 when the technology allowed solar panel providers to produce more solar panels at a lower cost, making them easier for consumers to access. Even so, they were still out of reach for most families.
The most popular size of solar panels for homeowners is four kilowatts. In 2008, the solar panels would cost the average homeowner about $ 32,000. Local incentives for clean energy that would publicly that the costs to be as low as $ 23,000. Electricity companies charge per kilowatt-hour. With the aid of 1,000 watts of electricity for one hour is the equivalent of this measurement. Having a 4 kilowatt panel running at capacity would save just one hour four kilowatt hours of electricity costs.
If the materials and technology needed to build solar panels became more affordable for businesses, the savings were passed on to the consumer. By 2009 would be a 4 kilowatt panel costs as low as $ 10,000. There prices are still beyond the reach of most consumers today, but there are cheaper alternatives.
Some solar wholesalers offer cheap solar panels, which is still running in the vicinity of several thousand dollars. Recently a number of do-it-yourself guides for the construction of solar panels have become popular. This solar panel building guides can build an effective panel for $ 100-200.
This is by far the cheapest option, with the result that many homeowners are looking to build their own solar panels at home. The cost of these homemade solar panels are easily offset by electricity savings resulting from them. The average home will increase the cost of building solar panels at home in a period of one to three months, compared with almost 10 years with the traditional solar panels have been restored.
