Why We Need Solar Systems As Standard Home Options

Solar photovoltaic and solar thermal systems are gaining in popularity, especially in the South West United States where, according to SolarBuzz.Com, growth rates for new solar system installations by 2014 will increase by as much as 10 times that of the market size in 2009. One would think that with such phenomenal growth rates, more home manufacturers, factor built builders especially, would add solar pv and solar thermal systems as standard options.

So why don't more manufacturers do this since the solar market seems to be taking off? The answer lies primarily in the development cost of associated with providing new options of any kind to consumers. Developing new home options that require complex engineering plans and designs is not cheap. A home builder that want to add energy efficiency options in to the mix of what they offer consumers can look at having to bankroll a development project for years before they may see any real return on investment. This, primarily, is the reason most installations of solar systems happen on existing homes and not be developers themselves.

Some home builders do offer these systems as options but, quite frankly, these companies are few and far between. We project that as the industry continues to increase in terms of demand, more home builders in the South West will look to add these options in to their regular product offerings to not only meet consumer demand, but also as a new profit center. Why should these systems be offered only after market?

California comprises almost 50% of all new solar system installations annually. Even though the housing market may be in a downward spiral, new home sales, especially in the manufactured home market, are doing well due mostly to the reduced overall cost as compared to site built homes. While consumers may turn to the factory built variety of homes to save their hard earned dollars, they still want high end options available to them.

Cost savings is one of the driving forces that makes consumers want to invest in solar systems. I predict that home builders that offer homes in the South West United States will begin offering more options to meet people's needs in the solar arena, not because its good to do so necessarily, but more so because of demand and the ability to create a new profit center within existing businesses. Energy efficient home options that include PV and solar thermal systems should be standard options in the near future.

Home Systems: Active Vs Passive Solar Heating Systems

Are you interested in using a solar heating system? If so, then you will have several options. One of the main ones is whether to choose an active or passive system.

What are Active Solar Heating Systems?

This type of system involves harnessing and storing (in the form of heat) solar energy. It uses fans and other objects to dispense heat that has been harnessed. Solar cells constructed of silicon are the most common type of solar heat collectors. Typically, the cells are contained on solar panels, which are located on the roof of a home.

What are its main types?

There are two primary types. Their difference lies in the material that captures and moves the heat that is located in the solar collector. Usually the material is a gas or a liquid. For instance, an air-based system usually involves transpired air collectors or air room heaters. On the other hand, liquid-based systems usually involve water (or antifreeze) to capture and move heat.

How much power does it provide?

Usually the goal of such systems is to heat up to three-fourths of a home's interior. When more solar energy than a house needs is produced, the homeowner could then sell excess power back to his or her local utility company. Also, it is advisable to heat both the air and water in your home, so your system can function throughout the entire year.

What Are Passive Solar Heating Systems?

This type of system is a low-technology method of capturing solar energy. It functions by directly capturing the sun's warmth, and then retaining it within the house for the function of heating. This is mainly achieved through methods such as quality insulation and windows. This type of system can lower your current heating costs, or even replace your home's current system.

What are its components?

Windows are the primary components of such systems. The goal is to maximize the amount of sunlight and heat that one can collect during the daytime. Typically, the windows consist of a special variety of glass that absorbs as much heat as possible-and then keeps it indoors for a maximum amount of time.

Besides windows, another common component of Passive Solar Heating Systems are trombes, which are a special type of wall. There is a pane of glass in front of the wall. The mission is for the space between the glass and wall to collect heat. Another method is to paint the concrete walls black, so they will absorb sunlight more.

What are its benefits?

This is generally an ideal option when you are looking for a solar heating system for a new home. The reason is that Passive Solar Heating systems are based on factors such as the location of the windows in the home, the location of the building itself, the amount of insulation in the building, and so on. These issues can be quite challenging to change within existing homes-and especially the location of the home!

After learning the basics of Active and Passive Solar Heating Systems, it is time to determine which one is best for you.
