If you’re new here, you may want to subscribe to my RSS feed. Thanks for visiting!Solar power in some form has been around for millions of years. Even the earliest humans benefited from the sun, since it makes plants grow and animals thrive. Early man soon learned to direct the sun to provide warmth. [...]
To implement solar power to heat and power your home requires a number of relatively expensive items. But those items can be cost effective over the long run. Still, going solar the right way requires the right technology and some planning.
First, you need to estimate how much electricity you require to run your home. If [...]
Using the energy from the sun to generate electricity gets a lot of press. But there are many other applications for solar power. One of the most important is for treating water.
Many countries around the world have impure water that causes diarrhea, typhus and other medical problems. The same is true of certain areas of [...]
Human use of the sun’s energy may seem like a recent phenomenon. But, in fact, solar energy has been in use in various forms for thousands of years.
Apart from the obvious fact that the sun provides the energy for plants to grow that feed us, there are more technological uses that go back millennia.
The ancient [...]
When most people think of solar power they imagine large, dark blue panels supplying electricity to a home or business. And that’s certainly one very popular application. But there are other ways to harness the energy of the sun. Solar heating is one, and its roots actually go much further back than the use of [...]
Though the claims of enthusiasts are sometimes overstated, it’s still true that solar power and alternative energy forms are viable and valuable. They’re low-pollution generating, even accounting for manufacturing effects to make the components. They are, in principle, inexhaustible sources of energy. And, those forms of energy don’t require looking to unstable countries to supply [...]
Solar power technology has been around in some form or another for thousands of years. Even many modern solar device designs are now decades old. Yet, they have not fulfilled the promise that many hoped. Why? Two reasons: efficiency and cost.
Of the approximately 1,000 watts per square meter of sunlight power falling on the surface [...]
The image of a large, dark-blue panel atop a rooftop supplying solar-powered electricity is now familiar. Though relatively few homes have them, thousands of magazine stories have been written over the past 30 years accompanied by photos depicting them. Because of their relative rarity, such systems have become regarded as ‘the wave of the future’, [...]
Using solar cell arrays to produce electricity is a now-familiar application. Most applications that use PV (photovoltaic) modules are still small scale, except for certain experimental stations trying to generate power at the level of utility companies. Still, everything from lawn lights to full power supply systems for homes are available.
But there’s another way of [...]
The cost of a solar system to power or heat your home can run anywhere from a few thousand dollars to $50,000 or more. The wide range of investment required is the result of many factors.
The amount of sunlight received in different areas varies considerably. Some places like Santa Fe, New Mexico get sunshine an [...]
