The advantage of using solar is that it is a method of harnessing renewable energy that is clean. The disadvantage of using solar is that there is initially a sizable investment to purchase and install solar panels. That being said, solar panels can pay for themselves in a matter of months or years. Today more than ever, people are becoming very interested in both saving money and saving the planet with eco-friendly solar panels.
Burning oil releases carbon dioxide and other greenhouse gases into the atmosphere, and if that isn't bad enough, obtaining oil destroys the environment and the risks of devastating oil spills when oil is transported are just not worth it. The green advantages of solar panels are that solar energy, unlike oil, is a renewable resource. Solar energy is also non-polluting.
The money saving advantages for individuals and businesses are that by using energy from the sun, it is easy to reduce the ongoing and increasingly more and more expensive costs of lighting, cooking, working, entertaining, heating and cooling. With solar panels you can greatly decrease or even eliminate monthly electric bills.
That's what everyone already knows.
So -- What's New in Solar Panels?
A lot.
If you looked into solar panels in the past and thought they were too expensive, difficult to install or maintain - then it is time to look again. If you're considering solar panels for the first time as a way to adopt more green and economical practices, you'll be pleasantly surprised. Due to lower prices, more user-friendly options, new technologies and laws, it is now a great time to invest in solar panels.
In the past, solar panels were expensive, and silicon, which is used as a semi-conductor in solar panels, was in short supply as well. As interest in solar energy and solar panels increased, (mainly due to the demand for computer chips) the price of silicon rose over drastically. Things are leveling out today as silicon production has increased to over 25,000 tons in 2007. It is predicted that by 2010, silicon manufacture will reach over 75,000 tons.
Even though there is a heavier demand for solar panels these days, new technologies are being developed that are cutting back some of the cost on both solar panels and on gathering the sun's energy. A new solar panel technology uses heliotubes as a conductor to track the sun and gather sunlight. These panels are larger but they are much less expensive than typical solar panels and positioning them is considerably more flexible.
In addition to the lower costs and increased efficiency of solar panels, tax credits are also making solar panels more attractive and affordable. Tax credits are generally more valuable than an equivalent tax deduction because a tax credit reduces tax dollar for dollar while a deduction only reduces the amount of income on which you are taxed. In addition to helpful federal tax credits, there are additional options in certain cities or states. Pittsburgh, Portland and Denver are working hard to make it easier to go green using solar panels. In these cities and a few others, it is possible to recoup part of the initial investment in solar panels through credits.
