Homeowners will have to consider a number of factors to determine which home solar power system is the ideal choice for them. Some of the crucial factors that you will need to consider are the availability of sunlight, size of the system, and the local permits you might need to collect from the local authorities.
In addition to that, you will also need to check whether your site is receiving an adequate amount of solar energy to meet the electricity needs of your home. You can contact a professional home insulation services provider for guidance if you feel that installing a solar power system is not an economically viable option.
It is recommended to consider the tilt of the solar panels and its geographic orientation, as both of these factors can have a huge impact on the performance of the Photovoltaic (PV) system. If you have already considered the above-mentioned factors, then you will need to thoroughly compare the difference between the popular residential systems, as it would help you to make an informed buying decision. Below are the 3 types of residential solar power systems to choose from.
Off-Grid Solar Power Systems
Most of the off-grid solar residential power systems are usually entirely disconnected from traditional power grids. These systems incorporate the use of batteries, which efficiently balances the periods of excess demands and production. Off-grid solar residential power systems are usually equipped with a generator, which offers extra protection to the system against shortfalls. If you are living in a remote area, then it is best to invest in an off-grid solar residential power system.
Grid Inter-Tied Systems
Grid inter-tied solar power systems are usually connected to a traditional electric utility grid and to the home of the user. This allows the system to draw power from the utility grids or from home electric systems. The best thing about grid inter-tied solar power systems is that they are highly efficient in balancing the energy production of the system and the power requirements of homes. Since this solar power system contains fewer components, it is relatively easy on the pocket as well.
Grid Inter-Tied Systems with Battery Back-Up
Just like normal grid inter-tied solar power systems, grid inter-tied systems with battery backup are also connected to a traditional utility power grid. However, the difference is that the latter system is equipped with additional battery backup. This solar power system offers greater protection against power outages as well as efficiently balances demand and production at the very same time.
