Solar Panels

Though the technology has been around for over thirty years, solar panels are really heating up as a growth industry. The demand for efficient panels is currently far outpacing supply and anyone who has money to invest in these or any other renewable energy source is sure to make some quick returns on their investment.

In just the last 15 years, solar panel technology has become far more efficient – nearly doubling in that time. At the same time, as production has ramped up and even respectable homes are now sporting collection panels, the price per kilowatt-hour has steadily dropped, even before figuring for inflation. Companies that make solar panel systems can hardly keep up.

Generally, residential solar panels fall into two types of designs in North America. There are those that directly heat water through a series of tubes behind a glass panel. These solar heating panels are relatively inexpensive, though they usually require professional help with the plumbing so as to avoid leaks. These are by far the most common and have been extensively used since the 1980s.

You may also build your own solar panel at home with some ingenuity and rubber tubing. These nearly free solar panels can even be made from found materials and cast-off building materials. With even a simple solar panel diagram, you can how to make a solar panel and design a system that can heat a surprising volume of water. For those who wonder just how do solar panels work, there is a wealth of information available online for those who wish to make a small solar panel.

The other sorts are the photovoltaic or solar power panels that actually generate electricity. These tend to be a bit less effective in cloudy weather than those that simply heat up water however, with the accompanying gear; you can store the electricity for use when it’s dark outside. These are far more expensive than the solar hot water heaters, but have the ability to make you a residual income from the sale of the power back to the power company.

As the price of oil has risen steadily in the last few years, and European countries are struggling to meet their obligations to reduce carbon emissions under the Kyoto and Montreal Protocols, solar panels are being snatched up as fast as they can be produced. For instance, a common 180-watt solar panel is nearly impossible to get in North America today because all those produced in China are being preferentially shipped to Germany and Austria because their governments are subsidizing those who build solar panel systems.

The shortage in the US has led many to utilize RV solar panels and even used solar panels in their designs, in part because the price has gone up in North America because of worldwide increase in demand since 2000. If panels are unavailable, you may have to build your own solar panel system.
