Many people talk like solar energy is the answer to our future energy supply. Since the Earth is constantly being bombarded with free energy, whether we use it or not, it would seem like a no brainer. So why aren’t we attaching solar panels to every roof if solar power is so great? As good as solar energy may sound, there are both pros and cons to solar.
If you are planning to build a new house, it would be better to install solar panels together with the house so that it will be easier to mount it to the roof. This can also lessen the cost of the installation. Plus, the panels can be secured well in the roofs to minimize its leaking. It is important that the panels should be done right so that it will work efficiently. el paso solar panels need to be secured to the rafters using stainless steel lag bolts. The rafters are still easy to find when there is no roof yet.
On the other side of the country, in the Southwestern United States, payback periods between the two technologies tend to converge more closely. As mentioned above, the extra days of sunlight make the solar panels more efficient, and the heating bills are also much smaller.
Spain was the world leader in newly installed PV solar energy (2,605 MW) in 2008 but has been overtaken by Germany as its new installed capacity decreased tremendously (to just 69 MW) in 2009.
From a relatively low starting point solar energy use is expected to rise rapidly in the US over the next few years,due to the large number of solar projects already in the pipeline. These were aided not only by supportive state level policies but also by the lifting of the Federal solar tax credit cap in 2009.
1) Wholesale solar panels will not work in cloudy places! UV light is all that is needed and even cloudy places have excelled when it comes to solar! Germany is currently the solar power capital of the entire world and they rank low when it comes to sunny days.
Installing residential solar power by building your own cheap solar panels is definitely a great financial investment and an excellent contribution to the environment for a greener world.
