The cost of many of the more traditional energy sources that we use, such as natural gas, gasoline and electricity are right there in front of us. Determining the overall cost of solar power, on the other hand, is not quite as simple. To make this process even more difficult, many of us have a hard time seeing not only the cost of solar panels, but the overall value. Unlike gasoline and other easily measured energy sources, solar panels provide their value over several years, rather than a few trips in the car.

How Much Do Solar Panels Cost?

In most cases, photovoltaic panels are priced by dollars per watt. Although many places will label things differently, this is the basis for most calculations. Whenever you purchase a solar panel system, you are essentially paying for the ability, or capacity to generate a certain amount of electricity, rather than a certain amount of energy to use until it is gone.

The overall cost of your solar panels will vary, depending on your individual project. Because each home is different, each project is different, making general quotes difficult. Furthermore, special tax programs that provide rebates and incentives can play a huge role in the cost of your panels. For an accurate cost, get in touch with solar installers in your area.

In addition to the varying costs of solar installation, are the various methods of purchase. The traditional form of buying panels outright and having them installed is less popular than it used to be. Many homeowners are now taking advantage of special financing for their solar panels. There are also many solar leasing programs out there, that we discuss at Solar panel Info. These programs allow you to lease a set of solar panels, and keep all of the energy that you generate. With all of these different options, generating solar power is much easier than ever before.

Electricians have been using copper for electrical wiring since the 1820s. It may surprise you to know that since then, we’ve never found, or needed, a replacement! Copper has numerous properties that make it ideal for electrical wiring. In fact, we can likely expect copper to continue to be used far into the future.

Ductile and Malleable—ductility and malleability are two very useful properties of metals. Something that is ductile can be hammered into a thin wire easily, and something malleable can be manipulated and bent into shapes easily. These properties make copper wires inexpensive to produce and easy to install.

Excellent conductivity—copper’s electrical conductivity is far superior to other types of non-precious metals, which allows it to carry greater amounts of current with a smaller diameter wire.

Non-corrosive—one of the biggest benefits of copper wiring is that it is non-corrosive, able to survive in harsh environments with almost no risk of wear and tear. It’s not uncommon to see copper wires last for 40 years or more!

All of these properties make copper the gold (or should we say copper!) standard in the electrical industry. For both commercial and domestic purposes, copper is considered the go-to material for wiring. In fact, most modern buildings being constructed today are designed to accept copper wiring. The prevalence of copper wiring makes rewiring a lot easier as well.

During the 1960s and 70s, aluminum wiring was used in many homes as a cheaper alternative to copper. Unfortunately, problems were discovered with aluminum wiring. The biggest danger associated with aluminum wiring is that it can react to materials used in outlets, light fixtures, and splices, where it can oxidize, deteriorate, overheat, and catch fire. The CPSC estimates that about 2 million homes were built with aluminum wiring between 1965 and 1973—and many of these homes are located in the MD, VA, and DC area.

The other problem with aluminum wiring is its high electrical resistance, which makes it more difficult for current to flow. As a result, you experience greater losses with aluminum wiring than you would with copper.

More than any other material, copper has stood the test of time for use in residential and commercial applications. If you’ve been thinking about rewiring your home and want to use the best materials possible, call Kolb Electric today!

What is Radiant Floor Heating and what are the advantages of it?? We get asked that often.

Radiant floor heating is the best heating system a house can have and one that you don’t realize it is there! Just imagine: no radiators clanking in the night and no vents whooshing like a jet preparing for take off!! No dust – collecting ductwork that runs up your allergist”s bills. That’s the advantage of radiant floor heating. It is an even blanket of heat, right where you want it. It’s also a highly efficient way to heat a house, increasing comfort as it reduces energy costs.

This is how radiant heat works – In a radiant setup, the warmth is supplied by hot-water tubes or electric wires buried underneath the floor. As the invisible waves of thermal radiation rise from below, they warm up any objects they strike, which radiate that captured heat in turn. Though the air temperature remains relatively constant, you stay comfortable because the surrounding surfaces aren’t stealing warmth from your body.

Contrast that with what happens in a conventional forced-air heating system, the kind found in most homes. Air blows out of the registers at a well-baked 120 degrees, rises to the top of the room where it quickly sheds heat, then drops back down as it cools. The air in the room becomes uncomfortably stratified: Your head can be bathed in warmth while your toes lie in the frozen zone. Then there’s the problem of cycling. “You turn on the furnace, it quickly takes you to 68 or 70, and then shuts off. The result is a phenomenon he calls “the cold 70,” which is what you feel right after the hot air stops pumping from the registers. Those jarring ups and downs are absent with radiant floors, which may reach 85 degrees, tops, on a frigid day. The warm air still rises, but it does so evenly over the entire floor, so the coolest air stays up at the ceiling.
