Solar power for residential service is becoming a more common occurrence all the time. More and more people are beginning to see the advantages of harnessing the energy of the sun to power everyday things. Not only does it make sense from money saving stand point, but it makes good ecological sense as well.
There are basically three different types of solar power residential service types available and in use today. They are utility-tie, utility-interactive and stand alone systems
A Utility-tie system is probably the most popular type solar system. This system has no batteries to worry about replacing, and costs in most cases considerably less than either of the other solar systems available today. The system usually consists of a multi panel solar array connected to a synchronous utility-grade inverter replacing power you normally would purchase from the power company with electricity produced from the solar panels Air Conditioning Installation and Repair.
These types of systems have the ability to slow, stop or even reverse the flow of power through your utility connected meter depending on conditions and the sunlight available for production of electricity. As you might imagine this is a system that is used in daylight hours only and returns your electrical system to normal grid usage during the night times hours. If you live in an area with fairly reliable, meaning few interruptions in electrical service this type of system is generally your best bet. Or if you already have a backup generator installed for night time usage when there might be a need for emergency use because of grid service interruption.
The Utility-interactive system has a battery and additional controls that allow switching between the normal grid system and a battery backup system. Under normal power connection conditions the system works very much like the standard utility-tied system above, allowing it to slow or reverse the flow of electricity at the incoming grid connected meter. During power failure the system switches to the battery backup side of the system allowing for uninterrupted power. Depending on the size of the battery storage system, it can supply power to an entire house or just a select few power controlled items that the user deems most important. The greater the battery storage, the longer time and more sources that can be supplied with electricity from the battery backup system. Equally, the more electrical storage the system has, the more expensive the system is to purchase and install.
The stand alone system is typically used when there is no public utility grid available. These systems are suited for remote areas and light electrical usage. Normally either a large amount of battery storage is required to use these systems during night time hours for any length of time. Normally a backup fuel run generator makes a more logical option in these instances.
