Solar power is not limited to supplying electricity to homes. Depending on the kinds of solar energy systems which can be being used, it is also capable of powering commercial buildings as well as RVs. In certain cases there is a choice to be made, yet, in some applications the choice is totally obvious. Take for example a solar power system to be being used for an RV, a portable energy system or a remote vacation cabin. The most effective solar power system to be being used should be the small stand-alone system. With fewer solar panels, these system is more cost effective than those of larger stand-alone system. With stand-alone system, all the energy that the solar panels collect during the day will be stored in batteries. An inverter is then utilized to turn the 12-volt DC energy of the batteries into the 120-volt AC energy of most house appliances. Many people whose homes are already connected to the utility grid will opt for a grid-tie solar power system. This gives them the most suitable of both worlds - the savings of the solar energy as well as the reliability of the utility’s power. They may also get tax breaks or rebates as incentives to purchase such systems. A special inverter is used for the grid-tie system to change the DC current into the purest sine-wave AC electricity in order that it will mesh with the utility grid for the electricity to be being used even on cloudy days as well as at nighttime. These system do not store up energy on batteries, though batteries are essential to be sure that owners will still enjoy electricity if there is a power failure on the grid. For people who want to be free of the utility grid, a complete stand-alone system is certainly recommended. This system is considered as the most environmentally-friendly among thermodynamic system since it doesn't use fossil fuels not like any other. The complete stand-alone system is much more complicated than the small stand-alone system. The complete system will contain much inverters, typically two, to ensure that there will be sufficient current to run large items like air conditioners. Another reason for the second inverter becomes clear when one needs maintenance. One can supply basic needs while the other one is down. Because of the high cost of installing a complete stand-alone system with its numerous solar panels and batteries to hold enough energy for any contingency, people just resort to buying it if their location is out of utility grid area as well as having electricity is impossible aside from getting it from an alternative source. Hybrid systems include the use of solar power with a generator of some kind as backup. The generator maybe diesel, gasoline, or propane. Fewer solar panels are needed for hybrid systems than for complete stand-alone systems. This is because the generator can begin working when the solar panels don't produce enough electricity. Given the different variations of solar power systems, it should be easy to find one that works perfect for any application. Its just a matter of assessing the requires and determining which system will do the trick. Also, considering the budget is one thing that matters in choosing a system.
