There is a small misconception amongst many homeowners when it comes to solar. Many believe that converting to solar means that they will no longer be able to rely on the grid. This however is not quite true in the majority of cases. Arizona solar experts state that the vast majority of small-scale photovoltaic systems are actually grid connected. Not only this, but they say that grid-tied systems are also considered to be the efficient systems for homes.

You may have heard phrases like free yourself from the grid, or even things like disconnect from the dirty grid system. However, Arizona solar companies state that grid-connected solar panels actually have positive benefits for America's overall energy infrastructure and for the homeowners who own them. One of the main reasons that they are considered to be the most effective solar systems is that they eliminate worry for homeowners.

The systems can still draw power by traditional means--through utility lines. Arizona solar officials state that this is a big benefit to homeowners because it means that when solar panels are not creating quite enough energy to power a home energy can still be drawn in through the utility lines. Along with this, grid-connected solar systems sometimes produce excess energy--on very sunny days, for example. In this case, Arizona solar authorities say that the energy is fed back to the utility companies for a credit. This potentially means that you could eliminate your electric bills entirely.

One of the most significant things about grid-tied solar panels is that they have an impact on the grid itself and on America's overall energy infrastructure. There is a term called "peak shaving" that Arizona solar experts use to define the way that grid-connected solar panels help to reduce congestion on the grid at times of peak energy usage. Peak shaving is important because it helps to decrease the risk of blackouts, brownouts, and other system failures that occur when the grid is overly congested.

The American Society of Civil Engineers gave America's energy infrastructure a D+ on its last report card. The nation's energy demands have increased by 25 percent since 1990 but the nation's energy infrastructure is not quite equipped to handle the increase, according to the ASCE. Not being equipped to handle new demands has been quite costly for the country, and Arizona solar experts state that while grid-connected solar panels can help combat problems there is still a long way to go. Upon the ASCE's last review of America's energy infrastructure they stated in their reports that "system wide failures" such as "power outages and power quality disturbances" have cost the nation between $25 and $180 billion a year.
