There is a common misconception about solar energy: A lot of people seem to think that the technology is not developed enough to make it a viable alternative to conventional power. In fact, nothing could be further from the truth. Solar panels today are incredibly efficient, with the best operating at around 35 percent efficiency — that is a lot when you consider that more energy reaches the surface of the Earth every single day than will be harvested from fossil fuels over their entire limited life span.
Solar energy is not the future. It is the present. All over the United States and all over the world, people are either taking the initiative themselves and installing solar power systems for their homes or businesses, or they are pushing their governments at all levels to fund solar projects through tax incentives. Yes indeed, it is an exciting time to be in the sustainable energy business.
Speaking of which, what could be more sustainable than solar? It’s not as if the sun is going to burn out any time soon. The average photovoltaic (PV) array has a life expectancy of 40 years now (their warranties are usually 25 years) and pays for itself after only 8-10 years, depending on the location. Very few investments will pay that kind of guaranteed return. After ten years, you’re getting free electricity for the next 15-30 years. Not bad. Actually, if energy prices keep rising as seems likely with billions of new consumers online in China and India, your PV array could turn out to be quite the bonanza from an investment standpoint.
The wide-angle-lens, big picture view makes more sense when thinking about solar power systems. In the short term, the cost of installing a solar system can be high, especially if you hire someone else to do it for you. The return is guaranteed, though, unless the sun burns out, in which case we will have bigger concerns than our investments.
There is an opportunity here, though, if you care to see it: Why not be that other guy whom people pay to install their solar systems? This is a business that is growing in leaps and bounds all over the country, even during this recession. Not only are homeowners installing systems, but large franchise businesses are as well. A large restaurant chain announced recently that it is undertaking a major solar project on many of its rooftops. I bought stock in that company when I heard the news — this is a company that takes the long view and expects to be around for a while.
People and businesses taking advantage of this technology today are the people and businesses of the future. But solar power is here now, and it is here to stay.

From the operators of www.GreenLivingRocks.com — providing education regarding how to build a solar panel, panels solar, and solar water heater.
Building your own solar swimming pool heater is a fantastic do-it-yourself project if you desire to add solar to your home. You will not need to buy a lot of expensive equipment or tools. And you will not need highly specialized skills. Here is a basic explanation of the procedure and benefits so you can decide if you want to tackle it.
The project payback time can be as short as 2 years in terms of energy savings. This is because you will be saving the cost of gas to heat your pool. And the cost of materials for constructing a solar pool heater is lower than with most other solar projects. You will also be saving the cost of installation if you decide to go ahead and do that yourself.
You will need to buy only a few simple components: solar collectors, piping, a controller and a diverter valve. You will not need to build or buy a storage tank, since your pool already stores the water. And you will not need to buy, build or install a circulating pump, since your solar pool heater will use your pool’s circulating pump.
Here’s a simple explanation of how the system works. The water from the pool gets pumped into the solar collector, gets heated by the sun and gets pumped back into the pool. This is called an open loop design. The controller allows you to select the warmest temperature you want the pool to reach. And the diverter valve either sends water back to the pool if it is already warm enough, or over to the collector to be heated as needed.
The solar collector is a simple system of black polypropylene UV-resistant tubing. The choice of supplies is important so that the tubing doesn’t break down from exposure to the sun or from exposure from the chlorine in the pool. The right materials will last up to 20 years.
Although it is appealing to think of doing it all yourself, including making the solar collector, it is really easier and more cost effective to purchase ready made collectors for your project. The reason is that adhesives will not stick to polypropylene, and the equipment you would need to thermal weld it would cost more than buying the ready-made collectors. Additionally, experts advise against using a cheaper rubber or plastic tubing that will break down too quickly because of exposure to the sun and chlorine.
If you choose that you really want to install your solar pool heating system yourself, the easiest way is to purchase a kit. You will still need to design measure and install your system. And you will be able to enjoy the fruits of your efforts for years afterwards.
With this ominous economy the make certain to is simply in saving money however, along with that we are all involved on preserving the earth, which usually comes along appropriate all the way down to saving electrical power along with water preservation. Solar powered energy subject . We tend to know we will be able to help save electrical power with taking solar power driven electrical power into each of our houses, although a lot of individuals may be still hesitant about it. However, most of us therefore need solar driven water heaters to help you support along with the conservation of water as well as cost effectiveness.
In case an individual have invested in a particular geothermal energy product and then the solar power warm water device is actually appropriate in order to be able to establish your own solar power product investment a lot more expense efficient. Solar driven water heaters minimize carbon wastes as well as these reduce our reliance referring to new electrical power as well as to be decreased price.
This solar power driven water heater applies solar power energy electricity somewhat rather than solar power electric (photovoltaic or pv) electrical power to help you heat up this water together with solar power uses longer wave as well as short wave energy. The solar power collector have to be postioned for ones own your home as well as close to your own house facing to the south. When the sun rays hits this glass this will probably likewise hit a good steel as well as rubber materials it are going to take up that sun rays. This material may convert the sun rays to help the long wave heat. This glass could continue to keep the heat by running released, working much for instance a greenhouse. The temperature of this solar cells might attain three hundred degrees Fahrenheit. As these are very simple, expense helpful and increased effectiveness the collectors utilized in solar heaters are a glass ripped plate. These types of tend to be created of a good shallow box, generally rectangular in shape, with the help of the translucent glass window protecting a good black plate as well as one with the help of a good stainless layer. This sheet is connected in order to no matter what form of tubing this water passes through. Regardless of whether it is a good series of tubes as well as the serpentine tube, the sheet is actually attached in order to this. Heat is actually therefore collected along with moved to this storage tank and this water is therefore heated. The solar heated water is therefore stored in a particular storage tank right up until an individual want it again. This storage tank of the solar power water heater to help accommodate more heated water as heat is only collected during this day.
